Section 17 leave is a provision under the Mental Health Act 1983 (MHA) in England and Wales that permits patients detained in hospitals under certain sections of the Act to be granted leave of absence. Not all leave of absence is provided for by S17. Throughout this article S17 means S17(1) to S17(5) with particular emphasis on S17(3). Other parts of S17 are not explored. To many S17 appears ‘simple’: the Responsible Clinician signs a ‘form’, and that’s the leave. S17 leave is often seen as ‘the Section 17 form’ or as ‘the form written up’. The writing up of the form is useless and baseless if the regulatory requirements underpinning the RC’s grant of leave have not been carried out.

S17 leave is not for a jaunt. It does not suspend detention. Its primary purpose arises from the need for treatment as defined in S145.

Section 17 leave is normally only available to patients who are detained under certain sections of the Mental Health Act 1983. These are – among others:
- Section 2: Detention for assessment.
- Section 3: Detention for treatment.
- Section 37: A hospital order made by a court (only if not restricted by a S41)
The RC has no power to grant leave of absence to patients who have been remanded to hospital by a court under ss.35 or 36, or who are subject to an interim hospital made under s.38. But the situation is far more complex in law.
The RC’s power to grant Section 17 leave is limited by the Secretary of State via S41(3)(c)i.
Section 17 leave is not leave for a jaunt. It is a powerful tool that is aligned to the purposes of habilitation and rehabilitation; anchored in the definition of treatment in Section 145 of the MHA 1983 (Amended 2007).
What does leave mean?
For detained patients
In England & Wales the legal meaning of the word ‘leave’ is permission. There are different kinds of ‘leave’ in UK law. For example, the words ‘leave to remain‘ in immigration law seems confusing to many i.e. “How can you be having leave and remaining?” What ‘leave to remain’ means, is ‘permission to remain’. Similarly the concept of leave in S17, is not about ‘leaving hospital detention permanently’ – though the patient leaves the hospital to some external destination.
According to the MHA Reference Guide (p215), “Responsible clinicians may give part 2 and unrestricted part 3 patients leave to be absent from the hospital in which they are detained, subject to any conditions they think are necessary in the interests of the patient, or for the protection of other people. Responsible clinicians may not delegate this power to anyone else.” But it is not that simple, because not all patients on detained on every section which under Part 2, engages S17.
CONCEPTUAL ANCHOR: Leave in the context of the Mental Health Act 1983 essentially signifies a relax limitations imposed by detention in hospital. It allows patients, under specific conditions and safeguards, to experience a degree of freedom and re-integration into the community while remaining detained under the overall framework of the Act. Detention means that certain Human Rights such as Article 5 (liberty) and Article 8 (family life etc) are limited by law. [Article 9 and 10 rights may be limited to some extent]. The point is that when on S17 leave Rights are already limited by the original section because the patient is still detained. The RC is given a discretion to relax limitations on those Rights for treatment purposes, not for a jaunt.
The extent of the ‘relaxation’ of detention varies depending on the type of leave granted, the patient’s legal status, and the assessment of their risks. Leave can range from short escorted trips within the hospital grounds to unescorted leave in the community, including overnight stays. The words ‘escort’, ‘escorted’ and cognate words, are euphemisms. The so-called escorts are exercising important duties of custody in law. Sometimes leave can be without custody and that is the so-called ‘unescorted leave’.
There is no provision in law for a relative to be given duties of custody, despite the CQC thinking that it is possible. The CQC does not make law nor has powers to change Parliament’s laws via S118 of the MHA 1983 (Amended 2007). Unbeknownst to many under S19(b) Delegation of hospital managers’ functions under the Act: The functions of the managers of a hospital in respect of the following— “authorising persons under section 17(3) (leave of absence from hospital) to keep in custody patients who are on leave of absence who are subject to a condition that they remain in custody;“. The reality is that this happens automatically because it is impracticable for the managers to specify that each S17(3) leave authorises nurse for example to keep custody of the patient on leave. Furthermore para 27.27 of MHCOP states. “A responsible clinician may direct that their patient remains in custody while on leave of absence, either in the patient’s own interests or for the protection of other people. Patients may be kept in the custody of any officer on the staff of the hospital or any person authorised in writing by the hospital managers. Such an arrangement is often useful, eg to enable patients to participate in escorted trips or to have compassionate home leave.” The ‘any person authorised in writing by the hospital managers‘ means that if an RC is to delegate a duty of custody to a relative, then such authorisation ought to be confirmed by the hospital managers in writing.
The Secretary of State for Justice can grant leave for patients detained under certain sections under Part 3 of the MHA which may or may not include permission for the Responsible Clinician to grant specified Section 17 leave. Leave is not discharge. The patient remains legally detained under the MHA, and the Responsible Clinician or other relevant authority retains the power to revoke the leave and recall the patient to hospital if necessary.
For Responsible Clinicians
Certain sections in the MHA 1983 (Amended 2007) do not afford powers to RCs to grant leave. That will be explored in depth later.
When patients are granted S17 leave they are still detained. RC’ duties of care are no less than when the patient is ‘in the hospital’. This means that for many patient’s RCs are still responsible for the Statutory duties:
- The interests of their patient’s health or safety [S2(2)(b), S3(2)(c)]
- Protection of others against risk arising from their patients [S2(2)(b), S3(2)(c)]
‘Recreational Leave’
Some NHS Trusts have in their electronic records platform, a S17 form for RCs to complete. One section is headed “Recreational Leave”. The inclusion of a “Recreational Leave” category on S17 forms is legally and clinically problematic. This terminology fundamentally mischaracterises the purpose of Section 17 leave under the Mental Health Act 1983. Section 17 leave is a therapeutic intervention within a treatment framework, not a recreational privilege or entitlement. The statutory basis for leave is rooted in treatment considerations, risk management, and rehabilitation for eventual discharge (as per definition of treatment in S145).
Creating tensions
This terminology risks undermining the clinical authority of Responsible Clinicians by implicitly suggesting that ‘recreation’ is a priority and it is ‘therapeutic’ for patient comfort or preference rather than treatment purpose. It weakens RCs’ positions when making difficult decisions to restrict leave based on clinical factors, as the very documentation suggests leave serves recreational rather than treatment purposes. Smoking tobacco easily falls within recreation.
From a governance perspective, such categorisation may create confusion about the standards that should be applied when granting or refusing leave. If leave is framed as “recreational,” this might suggest a lower threshold for approval than would be appropriate for a clinical intervention within a detention framework. This could inadvertently establish expectations that are inconsistent with the RC’s statutory duties regarding patient health, safety, and public protection.
The labelling under ‘recreation’ also raises questions about how such forms were developed and approved. It suggests a misalignment between operational systems and the legal framework of the Mental Health Act, highlighting a need for greater involvement of clinicians and legal advisors in the design of documentation that operationalises statutory powers. Trusts would be well-advised to review such terminology to ensure it accurately reflects the therapeutic purpose of Section 17 leave and reinforces rather than undermines the clinical decision-making that the Act places in the hands of Responsible Clinicians.
The challenge lies in the specific legal context of the Mental Health Act. When Parliament granted Responsible Clinicians the power to authorise leave, it did so within a framework of detention for ‘appropriate treatment.’ That anchor implies a more structured, clinical understanding of what constitutes “treatment purpose” as against simply anything with potential therapeutic benefit. If “recreation” is subsumed within “treatment” because it has therapeutic elements, the distinction becomes either meaningless or hard to find. There are no ‘X-rays’ in psychiatry to delineate the boundaries of concepts. Hence the practice of psychiatry ought to remain close to the original legal concepts.
Effect of semantic drift
The semantic drift to ‘recreation’ has practical consequences. Documentation that explicitly categorises leave as “recreational” stands to erode the clinical authority of RCs by repositioning leave decisions within a framework of patient privileges rather than its true anchor in ‘treatment’. The language we use shapes understanding and expectation—both for patients and for the professionals and administrators involved in their care.
For a patient with addiction issues or impulse control problems, certain “recreational” activities could directly counter therapeutic aims. Yet the terminology on these sorts of forms provides no framework for making these crucial distinctions. This further illustrates why administrative systems should align more precisely with the clinical and legal purpose of leave under the Mental Health Act.
What seems at first glance like mere terminology actually reflects deeper tensions in mental health practice: between clinical authority and patient autonomy, between legal frameworks and everyday language, and between different conceptions of what constitutes treatment within a detention setting. These tensions become particularly significant when leave decisions are contested or when different stakeholders bring varying interpretations to the table. The imprecision of language in this context is not merely academic (or pedantic) —it has tangible impacts on how powers are exercised, decisions justified, and conflicts resolved within mental health services.
What no one is saying
No one is saying that ‘recreation’ may not be ‘therapeutic’ but this acknowledgment masks a more fundamental legal distinction. The Mental Health Act establishes a framework where detention is justified specifically for the provision of “appropriate treatment,” not merely for activities that might have any old therapeutic benefit. The distinction matters because the law demands that restrictions on liberty be justified by necessity, and therefore relaxation of conditions not merely for recreational benefit.
Recreation may indeed have broad therapeutic elements—improving mood, reducing stress, providing social connection—but those ideas would be de-anchored from the original legal purposes of “appropriate treatment” within the meaning of the Act. The legal threshold is more stringent, requiring a direct connection to the patient’s mental disorder, its manifestations and associated disabilities. If we collapse all potentially ‘beneficial therapeutic’ activities – such as skateboarding or snorkelling – into the category of “treatment,” we risk diluting the specific legal test that justifies the significant restriction of rights involved in detention. The issue extends beyond semantics into the realm of legal authority and clinical governance. When documentation incorporates terminology that lacks clear legal definition, it creates a parallel system that may operate according to different principles than those established in law. This divergence between the language of practice and the language of law creates space for confusion, conflict, and potentially inappropriate exercise of powers under the Act.
Moreover, labelling leave as “recreational” suggests some part of leave is mainly for the patient’s enjoyment rather than as an essential component of their care plan. No one is saying that leave cannot or should not be enjoyable. The framing of S17 leave as ‘recreational’ subtly shifts leave from being a calibrated clinical intervention to being an easy discretionary privilege. Such a shift undermines the RC’s position when making difficult decisions based on clinical judgment, as it implies leave decisions should prioritise patient preferences rather than treatment needs.
Treatment affording recreation
Leave to purchase a pizza or to go to a cinema are indeed ‘recreational’ – but that does not mean that treatment objectives such as ‘money management’, ‘improved social competence’, ‘navigation to a venue’, ‘planning and organisation’ etc cannot be primary rehabilitation targets on the way to ‘recreation’. Yes – patients can and should have that recreation but whilst ensuring foremost that ‘rehabilitation’ is the central focus of the leave plan and leave evaluation.
Confusion
There is a confused situation requiring legal clarification about the nature of Section 17 leave authority.
Section 17 leave is explicitly granted by a specific Responsible Clinician to a specific patient under their care. The authority to grant leave is personally vested in the individual RC by Parliament through the S34 MHA 1983 (Amended 2007). Employers via an employment contract, may assign consultant responsibilities and duties. When when an employer names a consultant as RC for a patient, Parliament assigns power to the RC for various things including power to grant or withhold leave. An employer has no power to direct or supervise the RC what to do where/when Parliamentary power directs what the RC ought to do. If that was the case, then employers would have more power than Parliament – which would clearly be ridiculous. The most that an employer can do if it does not ‘like the RC’ for any reason, is to remove the assignment of the RC.
When RC responsibility transfers from one practitioner to another, previously granted leave does not automatically transfer with it.
This is because:
- The legal power is given by Parliament to a named individual (the RC) rather than to the role in abstract terms.
- A patient cannot have two RCs at the same time, nor can authority of one RC legally bind another RC at a different time.
- Leave decisions are based on clinical assessment and judgment made by a specific RC.
- The RC granting leave takes professional and legal responsibility for that decision.
Therefore previous leave authorisations become legally void when a new RC takes up those duties. Such as statement appears shocking to many psychiatrists and non-medical persons. Why? Because systems operate on cultures predominantly – not understanding of the law. When a new RC who does not know patients decides not to sign renewal of S17 or day 1 to 5 (for example), that is not “stopping leave for everybody“. The law says that the legal basis for previous leave authorisations (the judgment and authority of the previous RC) no longer exist. The leave ended automatically by operation of law rather than by a new RC taking an a decision to terminate it. The decision is Parliament’s. Some do not like to hear about that, though Parliament represents democracy. Parliament, through the Mental Health Act 1983, has structured Section 17 leave authority in a way that automatically terminates previously granted leave when RC responsibility transfers. This isn’t a discretionary decision made by the incoming RC but a direct consequence of how the statutory power is constructed.
This is not merely a technicality but reflects the core principle that detention powers and associated leave decisions must be exercised by identifiable clinicians who take legal responsibility for those decisions. Each RC must make their own assessment and exercise their own judgment rather than simply inheriting the decisions of their predecessors.
The Act vests the authority to grant leave specifically in the patient’s current Responsible Clinician as an individual professional power. When a new RC is appointed, the legal connection between the previous RC and the patient is severed, and with it, the legal basis for any leave they had authorised. It may be shocking – but that is what the law says – not what I say.

Implications for Responsible Clinicians
Statutory Duties During Leave
The RC’s statutory duties under the Mental Health Act 1983 continue unabated during periods of Section 17 leave, specifically:
- The duty regarding “the interests of the patient’s health or safety” as stipulated in Sections 2(2)(b) and 3(2)(c)
- The duty regarding “the protection of other persons” as equally stipulated in Sections 2(2)(b) and 3(2)(c)
Human Rights Obligations and Case Law
The case of Savage v South Essex Partnership NHS Foundation Trust [2009] is indeed significant. The Supreme Court established that Article 2 (Right to Life) of the European Convention on Human Rights places operational duties on healthcare organisations to take reasonable steps to protect patients from a real and immediate risk of suicide. This duty naturally extends to RCs when making decisions about Section 17 leave. An RC would be foolish to think or say, for example, “That’s for the Trust. This patient is at no real and immediate risk to life – nothing to do with me.” And that’s not going to be explained further.
Additionally, the case of Rabone v Pennine Care NHS Trust [2012] extended this duty to informal patients, reinforcing the scope of these obligations.
The Barrett Inquiry and Lessons Forgotten
The Barrett Inquiry – a homicide inquiry – took a deep dive into S17. It told everyone about systemic failures that contributed to homicide. It highlighted how organisational culture, systems failures and individual professional judgements can interact to create circumstances where preventable harm occurs. This underscores the importance of robust risk assessment before granting leave.
Enhanced Duty During Leave
Duties of care should be applied more diligently when granting Section 17 leave has considerable merit. The following factors support this position:
- Reduced protective factors The patient is removed from the structured, supervised environment of the ward where risks can be more readily monitored and managed.
- Exposure to risk factors Patients on leave may encounter situations or substances (including legal ones such as alcohol) that could destabilise their mental state or trigger relapse.
- Reduced monitoring Particularly for unescorted leave, the ability to observe changes in mental state is significantly diminished. The patient is freely exposed to a range of biopsychosocial factors.
- Delayed intervention Should a crisis develop, the ability to intervene promptly is compromised compared to an inpatient setting.
Legal Implications for Practice
This analysis suggests that RCs should:
- Conduct thorough risk assessments specifically addressing the circumstances of leave.
- Consider graduated approaches to leave (escorted before unescorted, brief periods before extended periods).
- Impose clear, proportionate conditions on leave when necessary.
- Engage with leave candidates on factors that may destabilise their mental state and provide appropriate advice.
- Ensure robust monitoring arrangements are in place.
- Document decision-making processes comprehensively, with particular attention to how identified risks will be managed.
- Review the outcomes of periods of leave before granting subsequent leave.
The courts would likely consider the RC’s adherence to these principles when determining whether duties of care have been properly discharged in the event of adverse incidents during Section 17 leave.
Additional Legal Implications for Responsible Clinicians
Proactive Risk Management
Pre-Leave Engagement and Advice
RCs should engage meaningfully with patients before granting leave to:
- Identify potential risk factors or triggers in the community environment
- Provide specific advice regarding substances or activities that may affect mental state
- Ensure patients understand how certain behaviours might impact their medication efficacy
- Document these discussions as evidence of discharge of duty
Responsive Withdrawal of Leave
The RC’s authority to revoke leave under Section 17(4) carries with it an implicit duty to exercise this power when appropriate. This means:
- RCs should establish consider thresholds for leave withdrawal. In practice it is very difficult to establish a clear threshold. The obvious ‘patient trying to jump of a bridge’ is not the sort of everyday ‘clear threshold’.
- Information channels should be in place to ensure timely awareness of destabilisation.
- A proportionate approach must balance therapeutic benefit against risk.
- Decision-making regarding revocation should be documented with clear rationale.
An RC normally would consult with a multi-disciplinary team when making decisions. However, the RC is not bound by a vote or ‘democratic process’ in making decisions.
Substance Use Considerations
When the word ‘substance’ is used mental health professionals usually think about cannabis, cocaine, other ‘street drugs’ and alcohol. Almost never is tobacco considered as a substance that can adversely impact mental condition, even though the science is clear:
- Smoking can indeed affect medication metabolism through induction of cytochrome P450 enzymes
- This may lead to reduced serum concentrations of certain psychotropic medications.
- Consequent sub-therapeutic medication levels could contribute to relapse.
- The RC may have a duty to consider this when setting leave conditions.
Proportionality in Practice
The legal standard of “reasonableness” would likely apply to decisions about leave conditions and revocation. This requires:
- Linkage between the identified risk and the imposed condition
- Evidence-based decision-making regarding interactions between substances and mental state
- Consideration of less restrictive alternatives where available
- Balance between autonomy and protection
Legal Accountability
In the event of scrutiny following an adverse incident, the RC would be expected to demonstrate:
- Awareness of specific risks pertinent to the individual patient
- Proactive steps taken to mitigate identified risks
- Responsiveness to new information indicating increased risk
- Proper consideration of the balance between therapeutic benefit and risk management.
The Practical Reality of Risk Assessment During Section 17 Leave
The Challenge of Clear Linkage
“Clear linkage” between relationship between risk factors and imposed conditions is indeed more theoretical than practical in psychiatric settings.
The clinical reality is characterised by:
- Complex causality: Mental state changes rarely have single, easily identifiable causes.
- Temporal disconnection: With smoking of tobacco, the impact on medication levels and subsequent mental state may take weeks to materialise.
- Information gaps: RCs often work with incomplete information about patients’ activities while on leave.
- Multi-factorial interactions: Various biological, psychological and social factors interact in ways that defy simple causal analysis.
- The patient may not disclose changes in smoking habits.
Smoking as an Exemplar
It is known that smoking has an impact on mental health. See: Nicotine Addiction: A Killing Mental Disorder
- Even if known, the precise impact of smoking on medication metabolism varies between individuals.
- The resulting reduction in medication efficacy may be gradual and subtle.
- Smoking has separate mechanisms that may impact people with mental disorders – but the absence of fully worked out mechanisms does not change the validity of the research.
- Other factors may compensate for or exacerbate the effects.
It is almost impossible for a RC to know exactly the impact on mental health for any individual patient. This should not be surprising because in like manner, no RC could possibly know exactly how beneficial a proposed medication for any individual patient. So – be it negative or positive impact, the expected impact is a probability estimate.
Nonetheless the projective negative impact of smoking on mental health is clearer than the beneficial effects of a medication for mentally unwell patients. Is that true? Yes it is. Antidepressants for example – according to recent research are much less effective for milder forms of depression than was thought of many years ago. Today antidepressants should be reserved for patients with moderate to severe depression. Whilst antipsychotics are tested for efficacy before being put on the market, no psychiatrist can say with great certainty that a particular antipsychotic will work for ‘a patient’. The flip-side of this is that no psychiatrist can say that smoking will be bad for ‘a patient’s mental health’ with any good degree of certainty. The issues are about clinical judgement and probabilities.
Legal Framework vs Clinical Reality
There is a tension between the legal expectation of evidence-based practice, clearly justified decisions, and the clinical reality of decision-making under uncertainty. Courts and inquiries may retrospectively identify “obvious” warning signs that were, in practice, obscured by the complexity and “noise” of real-world psychiatric assessment.
Implications for Accountable Medical Practice
Given this reality, RCs may need to:
- Document awareness of the limitations of risk assessment
- Maintain lower thresholds for caution when there is significant uncertainty
- Explicitly note potential interactions between observed behaviours and mental state, even when causality cannot be definitively established
- Develop staged approaches to leave that build in review points
A court might retrospectively ask why leave wasn’t revoked when smoking increased, without appreciating the genuine difficulty in establishing that this specific behaviour would lead to a specific risk materialising.
Balancing Legal and Clinical Considerations
This suggests that RCs need to maintain a delicate balance between:
- Meeting legal expectations regarding duty of care.
- Acknowledging the inherent uncertainties of psychiatric practice.
- Avoiding overly defensive practices that undermine therapeutic goals.
- Maintaining detailed documentation that reflects clinical reasoning, even when that reasoning necessarily involves uncertainty.
The law tends to seek clarity whereas clinical reality is often characterised by ambiguity—a tension that remains at the heart of mental health practice under Section 17.
Section 17 is law
Not well appreciated among many, is that Section 17 being part of the Mental Health Act 1983, is one of the highest forms of law. Acts of Parliament are primary legislation and under the doctrine of parliamentary sovereignty, are the supreme source of law in England and Wales. This means no other body or institution (such as NHS Trusts), CQC, or the courts, can overrule or invalidate an Act of Parliament.
In the context of Section 17 leave, this principle has some important implications:
- Compliance is mandatory: Health professionals and patients alike are bound by the provisions of Section 17. Any actions or decisions relating to Section 17 leave must adhere to the legal framework established by the Act and the Mental Health Act Code of Practice.
- Interpretation: While clinicians have discretion in exercising their powers under S17, this discretion must be exercised within the boundaries of the Act. The courts have the authority to interpret the provisions of S17 and provide guidance on their proper application.
- Challenges: Decisions made under S17 can be challenged through the legal system, for example, by way of judicial review. However, such challenges will generally focus on the legality of the decision-making process, rather than the merits of the decision itself. The courts will assess whether the decision-maker acted within their powers and followed the correct procedures as laid down by the Act.
However, even for patients detained under the sections listed above, the granting of leave is not automatic. The Responsible Clinician must assess whether granting leave is appropriate in each individual case, taking into account factors such as the patient’s mental state, the risk they pose to themselves or others, and any other potential benefits of leave.
Legal Status During Leave
Repetition is not necessarily a bad thing. It can aid learning. Section 17 leave represents a temporary relaxation of the physical constraints of detention, not a cessation of the detention itself. The patient continues to be “liable to be detained” under their original section. This means:
- The patient remains subject to the legal framework of the Mental Health Act 1983
- The detention order remains active and in force
- The patient has not been discharged from their section
- The Responsible Clinician maintains authority over the patient
Applicability
Leave is not simply for detained patients to have a break from conditions of detention. There is no ‘break’ because detention is still in force. The reason for that is because S145 sets out what treatment means – and that does not include or imply just having a break from detention.
Patients detained under other sections, such as Section 4 (emergency assessment) or Section 5(2), S5(4) (holding powers for inpatients), are not eligible for Section 17 leave. This is because these sections do not assign a Responsible Clinician.
The following sections do not afford the power for the RC to independently grant leave:
- Section 4: Emergency detention.
- Section 5(2): Holding power by medical doctor for 72 hours.
- Section 5(4): Nurses’ holding power for 6 hours.
- Section 35: Remand to hospital for a report on an individual’s mental condition.
- Section 36: Remand to hospital for treatment.
- Section 38: Interim hospital order to be imposed by a court while further information is gathered.
- Section 41: Restriction orders made by a court, then subject to Secretary of State approval of any changes.
- Section 47: Transfer of a prisoner to be detained at a hospital for treatment.
- Section 48: Remand to hospital of a prisoner for a mental condition.
- Section 49: Restriction order on transfer of remand prisoner.
- Section 136 – detention by the police.
Nothing in the MHA 1983 nor the MHACOP explicitly states that S17(3) does not apply to S4, S5(2) and S5(4). However, by virtue of S34 there is a reason why S17 leave is not possible under these sections. These intricacies will be explored later.
What’s happening for most patients held under Part 3 of the Act, is that the RC is afforded no power to grant leave at the outset. Only by special permissions from the Ministry of Justice (MOJ) or the Courts can the RC then be delegated power to grant leave.
Proportionality
The power to grant leave under Section 17 aligns with the principle of proportionality. It enables a graded and flexible approach to care, permitting a shift to a less restrictive environment when clinically appropriate, thus ensuring that the restrictions on a patient’s liberty remain proportionate to their clinical needs and the need to protect themselves or others. The words ‘least restrictive‘ are not part of any law. It was introduced by the CQC into the MHA Code of Practice, and many believe that it is ‘the law’ when it is not. CQC guidance is not law because the CQC has no authority to create new law. Lesser restrictive options were always to be considered as part of the proportionality principle and required no overstatement in terms of ‘least restrictive’.
Objectives of S17 leave
Section 17(3) of the Mental Health Act 1983 specifically relaxes restrictions on patients’ detention.
The granting of Section 17 leave is best characterised as:
- A relaxation of the physical constraints of detention.
- A treatment tool within the treatment plan.
- A controlled means of testing a patient’s ability to function outside hospital.
- A mechanism that remains under the authority of the Responsible Clinician.
The RC is effectively saying: “While you remain detained under the Act, I am authorising you to be absent or away from the hospital under these specific conditions as part of your treatment plan.“
Even when on Section 17 leave, a patient remains legally detained under the relevant section of the MHA. Section 17(3) does not suspend or end the detention; it merely relaxes the restrictions imposed by that detention. The patient is still subject to the authority of the Responsible Clinician and can be recalled to hospital at any time. The leave of absence is a conditional release, not a discharge from detention.
This distinction is crucial because it clarifies the legal status of the patient while on leave. They are not ‘free’ in the full sense of the word, but they are permitted a greater degree of freedom and autonomy than would be possible within the confines of the hospital.
Section 17 of the Mental Health Act 1983 does not explicitly state its purposes. However, the wording of the section, along with relevant case law and professional guidance, provides some insight into the aims and objectives of granting leave under this provision:
- Treatment benefit: Section 17 leave is primarily intended to be a treatment tool. It allows patients to experience life outside the hospital setting in a controlled and supported manner, which can aid in their recovery and rehabilitation. This is reflected in the requirement that leave must be granted “for the benefit of the patient“. The Code of Practice to the MHA further emphasises this, stating that leave should be considered an integral part of a patient’s care plan. The word ‘treatment’ is important because any patient on leave is still detained and under treatment (as defined in S145).
- Reintegration into the community: Section 17 leave can help patients gradually reintegrate into the community and adjust to life outside the hospital, as part of social rehabilitation (arising from S145 definition of treatment). Leave can enable patients to maintain contact with family, friends, and their community, which can be crucial for their overall well-being and recovery. This can involve re-establishing social connections, accessing community resources, and developing coping mechanisms for independent living.
- Assessment: Leave can be used to assess a patient’s progress and their ability to manage their mental health in a less restrictive environment. This is part of habilitation and rehabilitation (arising from S145 definition of treatment). It allows clinicians to evaluate the patient’s behaviour and functioning outside the hospital, which can inform decisions about future treatment and discharge planning.
It is important to note that this relaxation of detention is not absolute. The Responsible Clinician who grants the leave, can attach conditions to the leave, which may restrict the patient’s movements or activities. These conditions must be necessary for the patient’s welfare or for the protection of others, and they must be proportionate.
Furthermore, the patient remains liable to be recalled to hospital if their mental state deteriorates or if they breach the conditions of their leave. This ensures that the patient’s safety and well-being, as well as the safety of others, are protected.
In essence, Section 17(3) strikes a balance between providing patients with an opportunity to experience greater freedom and autonomy while ensuring that appropriate safeguards remain in place. It allows for a graded and flexible approach to care, enabling patients to gradually transition back into the community while still receiving the necessary support and treatment.
Types of leave
Not all leave is S17 leave. Some types of leave can only be allowed with the Courts’ permission or the Ministry of Justice.
| Section of MHA | Authority | Applicable to | Procedure | Purpose |
|---|---|---|---|---|
| Section 17 Leave | Responsible Clinician (RC) | Patients detained under Sections 3, 37, or 38, excluding those subject to a restriction order (S 41, S49) | The RC assesses the patient’s mental state, risk of absconding, and potential harm to self or others. They can impose conditions on the leave, such as time limits, designated areas, and supervision requirements. | Therapeutic and rehabilitative; allows patients to gradually reintegrate into the community while maintaining necessary safeguards. |
| Leave for Restricted Patients (Section 37/41) | Secretary of State for Justice | Patients detained under both Section 37 (hospital order) and Section 41 (restriction order) | The RC assesses the patient and makes a recommendation to the Secretary of State, who considers the RC’s report, the patient’s history, and public protection concerns before making a decision. | Carefully controlled and monitored reintegration into the community, with a strong emphasis on public safety. |
| Leave for Patients Transferred from Prison (Section 47) | Varies depending on the circumstances. May be granted by the RC, the Ministry of Justice, or the Parole Board. | Patients detained in hospital under Section 47 following transfer from prison for treatment. | Complex and depends on the length of the sentence, the nature of the offence, and the patient’s risk level. | To provide necessary medical treatment while ensuring public safety and maintaining the integrity of the criminal justice system. |
| Leave for Patients Remanded to Hospital (Section 48) | Generally not permitted, as these patients are remanded for urgent treatment. | Prisoners and those in detention centres transferred into detention in a hospital for treatment of their mental condition. | Leave is highly exceptional and would likely require court authorisation. | Limited to specific circumstances where leave is essential for the assessment process or for compelling compassionate reasons. |
Consent and S17(3) Leave
The responsible clinician has the authority to grant leave to a patient who is detained under the MHA, regardless of whether the patient has capacity or not. Underpinning consent is the concept of capacity, which refers to a person’s ability to make decisions about their own care and treatment. However, there is no capacity test that applies to S17(3) leave under the MHA. This is because leave is considered a grant. Patients who are incapable of deciding about leave conditions may be granted leave.
A patient may agree or disagree with the leave conditions. Compliance with the conditions attached to the grant, is required.
Entitlement to Section 17 leave
It often happens that patients use words suggesting that they are entitled to leave. Section 17 is a grant of leave. Under Section 17, leave is not an entitlement in the sense of an automatic right. It is not a ‘human right’.
The wording of Section 17 empowers the Responsible Clinician (RC) to grant leave “subject to any conditions they think are necessary.” This discretion, afforded to the RC, means that leave is not an inherent right, but a clinical decision based on a thorough assessment of the patient’s individual circumstances.
The Code of Practice to the MHA further clarifies that “leave should be considered an integral part of a patient’s care plan,” but it is not mandatory. The RC must weigh various factors, including the patient’s mental state, the risk they pose to themselves or others, and the potential benefits of leave, before making a decision.
Therefore, for patients detained under certain sections under Part 2 of the MHA are not ‘entitled’ to Section 17 leave in the sense of having an absolute right to it.
In alternative circumstances a patient may seek judicial review of the detaining authority, on a point of law, if a RC in the employ of the detaining authority did not reasonably consider and discharge duties of discretion about granting or withholding leave. The law on judicial review is a separate complex area of law. Not because a patient can take action to have judicial review, means that they have a right to leave.

Intricacies of S17(3) leave
Section 17 leave is relevant only in the following circumstances:
- The detained patient has an appointed Responsible Clinician or Approved Clinician.
- The section under which a patient is detained, allows the RC to grant leave.
The Section 34 effect

This section of the MHA 1983 interprets various parts of Part 2. Many people do no know it exists and will never have read it. For an instant headache try reading it now at your own risk.
The relevant part for our purposes is strangely stuck in from some amendment to the Act, that defines what the Responsible Clinician means.
“ the responsible clinician ” means—
(a) in relation to a patient liable to be detained by virtue of an application for admission for assessment or an application for admission for treatment, or a community patient, the approved clinician with overall responsibility for the patient’s case;
(b) in relation to a patient subject to guardianship, the approved clinician authorised by the responsible local social services authority to act (either generally or in any particular case or for any particular purpose) as the responsible clinician;]
This part of S34 is pure legalese i.e. by virtue of – what does that actually mean? It means ‘because of’ or ‘as a result of’.
Looking at the statutory language, note that:
- S2 requires an “application for admission for assessment”
- S3 requires an “application for admission for treatment”
- S5(2) requires a “report” by the “registered medical practitioner or approved clinician” – it is neither an application nor a recommendation
This difference in terminology is legally significant because:
- Section 34 specifically defines the responsible clinician in relation to patients detained “by virtue of an application”
- It makes no provision for patients held under a “report” mechanism – such as Section 5(2) – even when that section is implemented by a doctor who may be an Approved Clinician or Responsible Clinician.
- The Act creates distinct legal pathways with different procedural requirements
This explains why a patient under S5(2) would not have a responsible clinician as defined by the Act – the holding power operates through a different legal instrument (report) compared to the sections that explicitly establish RC status (via applications). In other words even if a doctor has Responsible Clinician status, that status is not assigned as such in S5(2). This is totally confusing for many patients and relatives. That is the nature of the law – and there is nothing ‘we’ can do about it.
Look at S5(2) again, very carefully this time:
5(2) If, in the case of a patient who is an in-patient in a hospital, it appears to the registered medical practitioner or approved clinician in charge of the treatment of the patient that an application ought to be made under this Part of this Act for the admission of the patient to hospital, he may furnish to the managers a report in writing to that effect; and in any such case the patient may be detained in the hospital for a period of 72 hours from the time when the report is so furnished.
Manipulative behaviour
Some patients believe that if they kick off or threaten to kick off that they will have a better chance of being granted leave. Their belief may well be grounded in a perception among some staff that the balance of risk to benefit is between kicking off and not kicking off. In other words it’s better to grant leave else the patient will be worse off for risk to self or others, for not being granted leave. What that means is that every patient who threatens to kick off or does so, will be granted leave – and there would be little point in Parliament creating S17 at all. The reality is that the grant of leave has no balance to make between kicking off and not kicking off.
When leave decisions become influenced by patients’ threats or actual disruptive behaviour, several serious problems emerge:
First, this approach fundamentally misunderstands the legal purpose of Section 17. Parliament created this provision to allow RCs to make clinical judgments about leave as part of a treatment plan, not as a behavioural management tool or negotiation point. The statutory power becomes undermined when leave is granted to manage ward behaviour rather than to serve therapeutic aims.
Second, this creates an inconsistent application of clinical standards. If patients who “kick off” receive leave while those who follow unit rules do not, the system rewards disruptive behaviour and potentially punishes compliance. This subverts the treatment environment. It could be seen as discrimination against patients who are unable or unwilling to engage in disruptive behaviour.
Third, this approach misconstrues the nature of risk assessment. The proper question is whether leave serves treatment goals and can be managed safely—not whether denying leave will provoke a reaction. When staff frame the question as “Will the patient kick off if denied leave?” rather than “Is leave clinically appropriate?” they’ve already shifted away from the legal framework of Section 17.

Some who got this far may be in of some paracetamol – a bit too late. Note the words ‘that an application ought to be made‘ – that’s not ‘an application‘. Essentially S5(2) is a report to the managers. It is not a recommendation either. Worse yet, the so-called ‘managers’ are not even the actual managers of the hospital. Did you see the words ‘registered medical practitioner’? That is not the RC. Did you see the words ‘approved clinician’ – that’s the clinician in charge but is not the RC. There is no RC when S5(2) is in force – hence no chance in law of a grant of S17 leave. If you are a lay person reading this and it ‘does your head in‘ then you have lots of company because it would ‘do the heads in’ of many mental health professionals too.
Fictional scenario
- A female patient on Section 3 MHA 1983 (Amended 2007) is admitted on an acute general psychiatry ward.
- Chronic history of recurrent episodes of schizophrenia.
- Chronic addiction to smoking – regularly consumed the equivalent of 2 packets (40 cigarettes) per week over last few years.
- Uses vapes and nicotine replacements when on the ward but has repeatedly asked for ‘fag leave’ (which is leave to smoke cigarettes).
- Her symptoms of paranoia and agitated mood are quite prevalent. On some days she paces the ward and has accused other patients of accessing her bank account and stealing money from her account. This is highly improbable on investigation. Reassurance does not assist her.
- Current medication is a small dose of zuclopenthixol 10mg/d (which will be optimised up and may take 4 weeks from steady state before evaluation of efficacy can be reasonably made).
- She is upset that her new RC does not grant her ground leave – which she intends to use for ‘fags’. Her previous RCs over several weeks allowed ‘leave for fags’.
- The RC eventually allowed leave to within the hospital (indoors), where she agreed she would not smoke – and not leave the hospital front door to smoke.
- However, on two occasions she was seen outside the front door of the hospital energetically smoking cigarettes – seemingly in an attempt to dose up on nicotine in order to get back inside the front door quickly.
- She had already been well advised on the deleterious effects of smoking on her mental and physical health.
Legal and Clinical Considerations
This case presents a complex interplay of detention powers, healthcare duties, and patient autonomy considerations. The RC navigated several competing factors:
Current Presentation and Risk Factors
- The patient is experiencing active psychotic symptoms (paranoia, agitation)
- Her medication regime is not yet optimised (zuclopenthixol at sub-therapeutic dose)
- She has demonstrated a willingness to breach the boundaries of her current leave permissions
- Her smoking habit may potentially interfere with medication efficacy
Legal Framework Considerations
- The patient remains detained under Section 3 and thus subject to the RC’s authority regarding leave
- The RC maintains duties regarding both her health/safety and protection of others
- Any leave restrictions must be proportionate and therapeutically justified
Actions by RC
- Maintained current restrictions with clear documentation linking the decision to:
- Active psychotic symptoms indicating current instability
- Need to establish therapeutic medication levels before expanding leave
- The patient’s demonstrated inability to adhere to current leave boundaries
- Considered and a graduated approach documented:
- Escorted non-smoking breaks as an interim measure
- Clear time limitations to manage nicotine-seeking behaviour
- Monitoring of mental state before and after smoking
- Documented a comprehensive rationale addressing:
- The impact of smoking on medication metabolism
- The relationship between current symptomatology and risk
- The balance being struck between restrictiveness and therapeutic needs
- That the patient was informed of the above considerations in non-clinical language.
- Engaged with the patient explaining:
- The specific reasons for current restrictions
- The conditions under which greater freedom might be granted
- Alternative approaches to managing nicotine cravings: vapes and greater use of NRT.
The RC’s decision-making reflected a clear understanding that leave restrictions are not punitive measures for boundary violations but therapeutic decisions based on current mental state, risk assessment, and treatment needs. Any restrictions would be regularly reviewed as the patient’s clinical presentation evolves.
There was a serious shortage of staff. It was not possible to provided an escorting nurse indoors within the hospital. P was granted shorter leave periods of 15 minutes three times per day, but was still spotted outside the front door smoking. Some staff argued that there was no clear evidence that her mental state deteriorated for her level of smoking. However, the RC noted that P’s medications were not yet optimised and she is missing doses (non-compliance).
Actions by the RC
Reassessed leave parameters and documented:
- The patient’s continued boundary violations suggested current leave arrangements are ineffective
- Non-compliance with medication introduces additional instability
- The combined effect of these factors may justify temporarily suspending unescorted leave
Documented a clear risk formulation addressing:
- The interrelationship between medication non-compliance and smoking
- The inability to provide necessary supervision due to staffing constraints
- The significance of boundary violations as potential indicators of impaired judgment
Engaged multidisciplinary perspectives by:
- Formally addressing staff disagreements about the impact of smoking
- Providing educational scientific references about smoking and mental health.
- Documented diverse clinical viewpoints while maintaining clear decision-making authority
- Establishing objective criteria for monitoring the patient’s response
Considered targeted interventions such as:
- A behavioural agreement regarding leave conditions
- Increased monitoring of medication compliance
- Implementation of supervised medication administration
The patient continued to smoke on short periods of leave that were supposed to be indoors in the hospital. The RC had little option but withdraw leave in order to protect the patient’s mental health. The patient has escalated the situation by submitting a complaint against the RC. The patient said that other consultant RCs in the hospital are allowing patients out for fag leave , that it is her Human Right to smoke, and that the RC “cannot stop me from smoking.“
Current Situation Analysis
This development represents a significant escalation with both clinical and procedural implications:
RC’s Position Following Leave Withdrawal
The RC’s decision to withdraw leave appears justified based on:
- Repeated boundary violations despite clear parameters
- Continued smoking despite education about risks
- Ongoing medication non-compliance
- Active psychotic symptoms that remain uncontrolled
The withdrawal of leave is not punitive but represents a necessary clinical response to the patient’s inability to adhere to the conditions of leave, which were established for therapeutic purposes.
Complaint Management
The complaint introduces a new dimension that requires careful handling:
- The complaint should be processed according to established trust procedures
- The RC provided comprehensive documentation of:
- The clinical reasoning behind each leave decision
- Evidence of proportionate responses to boundary violations
- Documentation of discussions with the patient about leave conditions
- Multidisciplinary input into decision-making
- The RC’s focus remained connected to clinical justification rather than authority conflicts
Legal and Clinical Accountability
The RC’s position remains defensible if:
- Each decision was based on assessment of the patient’s mental state and risk
- The leave withdrawal followed a reasonable, stepped approach
- Clear links were established between the patient’s behaviour and clinical concerns
- Decisions were documented contemporaneously with clear rationale
- The focus remained on the patient’s health and safety throughout
Moving Forward
The clinical relationship became strained, but the RC must continued to:
- Maintain focus on stabilising the patient’s mental state
- Work toward medication optimisation and compliance
- Consider whether a second opinion might be beneficial
- Continue regular reviews of leave status with clear criteria for reinstatement
The complaint, while challenging, does not alter the RC’s fundamental duties under the Mental Health Act, which are to act in the interests of the patient’s health and safety and the protection of others.
Legal and Ethical Tensions in the Case
Response to Patient’s Arguments
The patient’s arguments present several dimensions that the RC must address:
Comparison to Other RCs’ Decisions
The fact that other consultants may allow “fag leave” is not determinative for this individual case. Each RC must make decisions based on:
- The specific clinical presentation and risk profile of the individual patient
- Their professional judgment regarding this specific patient’s circumstances
- The particular treatment plan and medication regime in place
Other RCs’ decisions for other patients with different presentations cannot override the treating RC’s clinical judgment for this specific patient.
Human Rights Claims
While the patient frames smoking as a “Human Right,” the legal position rather different:
- Smoking is not specifically protected as a human right under the ECHR or Human Rights Act
- Article 8 (right to private life) may be engaged, but is not absolute
- Lawful detention under the Mental Health Act already permits proportionate restrictions on certain rights
- Any restrictions must be proportionate, justified, and clinically appropriate
Authority Regarding Smoking
The patient’s assertion that the RC “cannot stop her from smoking” mischaracterises the situation:
- The RC is not preventing smoking entirely, but rather managing the conditions under which leave is granted
- Section 17 explicitly grants the RC authority to impose conditions on leave
- The decision is based on the RC’s overall clinical management, not solely on smoking
RC’s Position
The RC could address these arguments by:
- Acknowledging the patient’s frustration while maintaining focus on her specific clinical situation
- Explaining that decisions about leave are individualised based on current presentation, treatment stage, and risk assessment
- Clarifying that while smoking itself is permitted when not detained, the conditions of leave are determined by clinical factors including medication compliance
- Documenting that restrictions are proportionate given:
- Current active psychotic symptoms
- Non-optimised medication
- Medication non-compliance
- Previous boundary violations
The RC must strike a balance between addressing the patient’s concerns and maintaining appropriate clinical boundaries, all while fulfilling legal duties of care within the framework of detention under Section 3.
Investigators of the complaint said that there was no evidence that the patient’s smoking adversely affected her mental health. The RC relied on a wide body of research some from the WHO (previously shared) which showed a clear link between poor responsivity to treatment with greater relapse rates and more serious symptoms when patients relapse. The RC stated that P’s mental health is not well controlled as yet. RC acknowledged that there appeared to be no impact on her mental health so far – which was his main concern. However, the RC remained concerned about poor responsivity to treatment, poor compliance, continued smoking and foreseeably a longer stay in hospital. The RC contended that it was both in the patient’s interests and the Trust’s interests to reduce bed-occupancy durations.
Commentary
The investigation highlighted a key tension in psychiatric practice: the gap between population-level evidence and individual clinical manifestations. This presents several considerations:
Evidentiary Standards
The investigators appear to be applying a standard requiring:
- Direct, observable evidence of smoking’s adverse effect on this specific patient
- Temporal proximity between smoking and symptom exacerbation
Meanwhile, the RC has relied on:
- Population-level evidence from research literature and WHO guidance
- Preventative reasoning based on potential rather than actual harm
- Concerns about treatment responsivity and long-term outcomes
Clinical Preventative Approach vs Reactive Management
The RC’s approach reflects preventative clinical reasoning:
- Anticipating potential interference with treatment before it manifests
- Considering long-term outcomes rather than immediate effects
- Managing cumulative risks rather than waiting for clear causation
Contextual Factors
The situation involves multiple interacting factors:
- Active psychotic symptoms that remain uncontrolled
- Medication that is not yet optimised
- Medication non-compliance
- Boundary violations regarding leave conditions
Implications for the RC’s Position
The RC’s position remains defensible if framed as:
- A holistic approach to treatment that considers multiple factors in combination
- A preventative measure based on reasonable clinical expectations rather than reactive management
- A temporary measure during the acute treatment phase while working toward medication optimisation
The RC should acknowledge that, while no direct evidence of smoking’s impact on this patient’s mental state has been observed thus far, the decision was based on:
- The broader clinical picture including medication non-compliance
- The established evidence base regarding smoking and treatment outcomes
- The need to establish a stable foundation for treatment during the optimisation phase
This represents the balance between individualised care and evidence-based medicine that characterises good psychiatric practice within the Mental Health Act framework.
During the investigation senior Trust managers got involved and stated that policy allowed patients to smoke when on unescorted leave. The RC contended that their actions seemed to limit the powers given to RCs by parliament via Section 34 of the MHA 1983 (Amended 2007).
Commentary
Statutory Authority vs. Trust Policy
This development introduces a significant legal and governance tension:
RC’s Statutory Powers
Section 17 of the Mental Health Act 1983 explicitly vests the power to grant leave, set conditions, and revoke leave in the Responsible Clinician. This is a statutory power granted by Parliament that cannot be overridden by hospital policy.
Section 34 (as you correctly reference) further clarifies that it is the RC who has authority regarding treatment decisions for detained patients. These powers are intentionally assigned to clinical decision-makers rather than administrative managers.
Trust Policy Limitations
While Trust policies can establish frameworks for implementing the Act:
- They cannot diminish or override the statutory powers explicitly granted to RCs
- They can guide but not dictate clinical decision-making in individual cases
- They must be interpreted in a manner consistent with the primary legislation [Statute law – the MHA 1983 (Amended 2007)]
The Legal Hierarchy
The correct legal position is:
- Primary legislation (Mental Health Act) takes precedence for RC’s duties.
- Case law interpreting the Act provides binding guidance
- The Code of Practice offers statutory guidance
- Trust policies must operate within this framework
Implications for This Case
The Trust managers’ position appears to misunderstand the legal relationship between policy and statutory authority:
- The RC’s authority to make individualised decisions about leave conditions stems directly from Section 17
- Trust smoking policies may establish a general framework but cannot remove the RC’s discretion
- Clinical decisions based on individual patient needs take precedence over blanket policies
The RC could reasonably maintain that:
- The decision was based on individual clinical factors including medication non-compliance and boundary violations
- The restriction was proportionate given the specific circumstances of this case
- The statutory authority of the RC under Section 17 cannot be limited by Trust policy
- The decision represents an exercise of clinical judgment within the RC’s legal remit
This represents a situation where administrative policy appears to be encroaching on statutory clinical authority, raising significant questions about governance within the Trust’s implementation of the Mental Health Act.
The Operational Reality of Contested Clinical Decisions
Time and Resource Implications
The case illustrates the extraordinary time burden that contested clinical decisions can create:
For This Single Case
- Initial clinical assessment and leave planning
- Discussions with the patient about leave conditions
- Responding to boundary violations
- Reassessment and documentation following incidents
- Staff education about the clinical rationale
- Managing the formal complaint process
- Providing evidence and justification to investigators
- Engagement with senior Trust managers
- Navigation of policy vs statutory authority tensions
- Ongoing clinical management despite these distractions
Each of these steps represents hours of professional time that could otherwise be directed toward clinical care.
Multiplied Across a Caseload
A new diligent RC doing their best for patients, applying law and ethics appropriately, could be faced with say four similar cases – only to encounter:
- Potential domino effects as patients observe outcomes of others’ complaints
- Exponential increase in administrative burden
- Significant diversion from core clinical responsibilities
- Risk of defensive rather than optimal decision-making
- Pressure to standardise approaches rather than individualise care
System-Level Implications
This fictional scenario reveals profound systemic issues:
- The tension between resource constraints and clinical needs
- Unclear governance structures regarding clinical authority
- Misalignment between policy and statutory frameworks
- The burden placed on clinicians navigating these contradictions
The RC must somehow balance their professional duty to each patient with the practical reality of time constraints, while also defending their statutory authority against administrative encroachment.
This creates an almost impossible situation where thorough, well-documented, individualised care becomes practically undeliverable across a full caseload—raising serious questions about whether the system surrounding the fictional scenario can support the level of care that the law assumes and requires.
The evidence is robust regarding tobacco’s negative effects on mental health outcomes, including prolonged symptoms, increased relapse rates, and more severe relapses. Facilitating smoking through leave arrangements could inadvertently perpetuate nicotine dependence (ICD-11 code 6C4A.2), potentially worsening patients’ mental health conditions after discharge.
To help evaluate mental stability and health in relation to smoking for detained inpatients, the followng assessment sequence seems reasonable:
- Clinical assessment of current mental state and stability, focusing on primary symptoms of their mental health condition.
- Evaluation of nicotine dependence severity and its relationship to their primary mental health condition.
- Documentation of clinical reasoning that links smoking to the patient’s specific long-term mental health risks, emphasising the cumulative rather than acute effects.
- Assessment of how continued facilitation of smoking through leave arrangements might affect the patient’s overall treatment trajectory and long-term prognosis.
- Consideration of nicotine replacement therapy (NRT) options during Section 17 leave as an alternative that addresses physiological dependence.
- Regular review of the management plan based on changes in clinical presentation and response to the approach taken.
The above framework aligns with GMC standards on providing evidence-based care that serves patients’ needs, recognising nicotine dependence as a mental disorder requiring appropriate management rather than facilitation.
Conclusion
The legal framework of Section 17 leave creates a delicate balance between therapeutic optimism and risk management. While the Mental Health Act grants Responsible Clinicians significant authority to manage leave, this authority exists within a complex system of duties that places them at the nexus of competing obligations. Ultimately the patient’s safety and mental health very high priorities. But RCs must balance clinical judgment with legal responsibilities, patient autonomy with public safety, and evidence-based prevention with observable deterioration. This tension is not merely theoretical but manifests in daily clinical decisions that have profound consequences for both patients and practitioners.
The clinical reality of psychiatric practice frequently diverges from the theoretical clarity of the law. Mental health presentations rarely offer clear causal relationships or predictable trajectories, creating a ‘noisy’ environment where decision-making occurs under conditions of uncertainty. RCs must navigate this uncertainty while maintaining accountable positions regarding their duty of care. The gap between population-level evidence and individual presentations further complicates this terrain, as clinicians attempt to apply research findings to unique cases where direct cause-and-effect relationships remain elusive.
Institutional contexts can create additional layers of complexity. Trust policies, resource constraints, and governance structures may come into tension with the statutory authority vested in RCs by Parliament. When administrative frameworks attempt to standardise approaches to leave, they can inadvertently undermine the individualised assessment that lies at the heart of good psychiatric practice. This creates situations where clinicians must simultaneously defend their clinical decisions and their right to make those decisions, often at significant cost to time and resources that might otherwise be directed toward patient care.
Terms such as “recreational leave” and “therapeutic” lack legal precision. They exist in a more fluid conceptual space without clear statutory definition or judicial interpretation. This vagueness creates a problematic disconnect between the legally defined purpose of detention (providing appropriate treatment) and the less clearly defined purposes for which leave might be granted. This disconnect becomes particularly significant when making and documenting leave decisions and evaluating progress for money spent on leave. While the RC must operate within a framework of “appropriate treatment” to justify detention, the documentation platforms they’re provided may use terminology that sits outside this legal framework. This misalignment potentially undermines the coherence of the entire detention and leave system. Healthcare organisations ought to be invested in delivering the real treatment objectives of detention (and leave) instead of vague pleasurable activities devoid of real treatment purpose.
The law requires precision precisely because it deals with restrictions on liberty. When the terminology used in practice drifts away from these precise legal anchors, it risks creating a parallel system of practice that may not fully align with the legal powers and duties Parliament intended. This exemplifies how administrative systems and documentation can subtly reshape the exercise of statutory powers in ways that may not have been anticipated by legislators.
The cumulative effect of these tensions creates an operational reality that threatens to overwhelm clinical judgment with procedural demands. With multiple complex cases requiring nuanced decision-making, RCs face not only the challenge of making the right decision for each patient but also of justifying, documenting, and defending those decisions across multiple forums. This raises profound questions about whether the current system can realistically support the level of individualised care that both the law and good practice demand. Perhaps the most important conclusion is that the legal framework, while necessary, must be supported by organisational cultures and resources that enable rather than impede the exercise of clinical judgment in service of patient wellbeing.
