I am fully aware that the UTT was seized of an issue stated as “This case is about the issue of “equality of arms” in terms of expert evidence at mental health tribunals, and in what circumstances fairness might necessitate adjourning to give a patient an effective opportunity to challenge the detaining authority’s case. ” That was a specific point of law. The case of OO is valuable from other perspectives: clinical and risk evaluation. The full judgement is at OO v Central and North West London NHS Foundation Trust & Anor (Mental health) [2024] UKUT 190 (AAC) (28 June 2024)
Caution: Complex case with specific legal context. No criticism of doctors or the Tribunals is made or implied.

Introduction to the Case
OO, a man with paranoid schizophrenia and a history of sexual offences, found himself entangled in a complex legal and medical battle after reoffending in November 2021 while on conditional discharge—a form of supervised release. His case, now before the Upper Tribunal, exposed critical tensions between procedural fairness in mental health tribunals and the clinical realities of risk assessment.
Initially, OO’s discharge seemed imminent. His care team, including his responsible clinician Dr Padayatchi and forensic psychiatrist Dr Kottalgi, supported conditional discharge, citing his clinical stability and confidence in community safeguards. Trusting this consensus, OO chose not to involve an independent expert, a decision the Upper Tribunal later deemed reasonable. However, days before a pivotal hearing, the care team reversed its stance. Dr Nyein, OO’s new responsible clinician, abruptly opposed discharge after reviewing reports from forensic psychiatrists Dr Brown and Dr Baruah, who deemed OO “unsuitable for community placement.”
The timing of this reversal left OO in a precarious position. With no opportunity to secure his own expert or cross-examine Dr Brown and Dr Baruah—whose evidence heavily influenced the decision—OO faced a stark imbalance. The First-tier Tribunal upheld his detention, relying on unchallenged forensic opinions that lacked clear clinical rationale. The Upper Tribunal later ruled this process unfair, emphasising the “equality of arms” principle: OO was denied a meaningful chance to contest evidence central to his loss of liberty.
Clinically, the case raises salient issues for reflective practice. OO’s 2021 reoffending —a sexual assault committed while conditionally discharged – would normally have been a focal point for risk evaluation. It probably was but that was not a focal point for the Tribunals’ legal consideration on a narrow point of law. We are left unaware as to why did Dr Brown and Dr Baruah conclude OO posed an elevated risk (due to the nature of the case before the UTT). It would be interesting to learn if assessments addressed his mental state, treatment adherence, or the specifics of the Nov 2021 offence. This does not mean that clinicians or the Tribunals were at fault.
The proposed “community care package” was cited as “pending” but never finalised. No unescorted leave had been trialed to test OO’s readiness, and the forensic team’s late objections highlighted unresolved concerns about community supervision.
This case underscores the fragility of clinical consensus in high-stakes decisions.
Understanding the Upper Tribunal’s Focus
The Upper Tribunal’s decision centred on procedural fairness, specifically the principle of “equality of arms,” which ensures both parties have a fair chance to present their case. The Tribunal did not scrutinise the specifics of OO’s November 2021 offence. Instead, it focused on whether OO was denied a fair opportunity to challenge expert evidence used to justify his continued detention. The First-tier Tribunal (FTT) had refused multiple adjournment requests, even after OO’s care team reversed its position on his discharge days before the hearing. This left OO unable to secure independent expert evidence or cross-examine key witnesses, creating an imbalance that violated procedural fairness.
The Illusion of Consensus Among Clinicians
Initially, OO’s discharge seemed supported by his care team. Dr Kottalgi (forensic psychiatrist) and Dr Padayatchi (responsible clinician) recommended conditional discharge, citing manageable risks. However, days before the November 2022 hearing, Dr Nyein (new responsible clinician) reversed this stance after reviewing reports from Dr Brown and Dr Baruah, who opposed discharge. The community forensic team also raised concerns. This shift left OO unprepared, as he had relied on the initial consensus and opted not to hire an independent expert. The Upper Tribunal noted this reversal was based on forensic expertise OO could not challenge, thus violating fairness.
Agreements and Disagreements on Conditional Discharge
| Clinician/Expert | Position on Conditional Discharge | Key Details |
|---|---|---|
| Dr Kottalgi | Agreed(May 2022) | Consultant forensic psychiatrist who supported discharge, citing OO’s stability and manageable risks. |
| Dr Padayatchi | Agreed(July–Sept 2022) | Responsible clinician who initially supported discharge, pending community assessments and funding. |
| Dr Nyein | Initially neutral, later opposed(Nov 2022) | New responsible clinician who initially deferred to Dr Padayatchi but reversed position after reviewing Dr Brown’s report. |
| Dr Brown(Forensic Team) | Opposed(Nov 2022) | Consultant forensic psychiatrist who concluded OO was “not suitable for community placement” (report dated 20 Nov 2022). |
| Dr Baruah(Forensic Team) | Opposed(Nov 2022) | Community forensic psychiatrist whose email (7 Nov 2022) influenced Dr Nyein’s reversal. |
| Community Forensic Team | Opposed(Nov 2022) | Expressed concerns about OO’s suitability for community placement, prompting the responsible authority’s adjournment request. |
Unexplained Shifts in Clinical Opinion
The judgment did not explore clinical rationale for why experts like Dr Brown and Dr Baruah deemed OO unsuitable for discharge (bearing in mind always the UTT’s legal focus). Their reports influenced the care team’s reversal, but the Tribunal did not (or need not) explore whether their conclusions addressed OO’s mental state, risk factors, or offence details (because of their specific legal focus). The Upper Tribunal emphasised the procedural unfairness of relying on unchallenged expert evidence and therefore did not need to dissect clinical merits.
Clinical and Risk Issues arising
Do not confuse or conflate generalities with specifics
The judgment need not be occupied with the critical details about OO’s November 2021 offence, which occurred while he was conditionally discharged, due to focus on a specific point of law.
From a clinical perspective in general, psychiatrists assessing readiness for discharge ought to evaluate:
- Clinical stability: Whether a patient’s mental disorder is well-managed, their adherence to treatment and cooperation with projected community care.
- Risk factors: Static risks (e.g., history of sexual offences) and dynamic risks (e.g., impulsivity, lack of victim empathy).
- Community management: The feasibility of a care plan, including supervision, accommodation, and relapse prevention. In many situations leave is useful mechanism to test a patients willingness to cooperate with community care.
- Forensic context: Sexual violence risk assessments are necessary and must be updated with the latest available information.
The above is not a full ‘prescriptive list’.
CAUTION: The above points are generalities and do not imply failures of care by person’s involved in OO’s care.
Conclusion
The Upper Tribunal’s decision rightly addressed procedural flaws and necessarily sidestepped deeper clinical questions. OO’s case underscores the tension between legal fairness and clinical rigor in mental health tribunals. Without thorough risk assessments and transparency in expert reasoning, discharge decisions risk compromising both patient autonomy and public safety.
While OO was justified in believing there was initial consensus (May–Sept 2022), the forensic team’s intervention (Dr Brown/Baruah) fractured this agreement. The care team’s lack of unified support by November 2022—coupled with the Tribunal’s reliance on unchallenged expert evidence—rendered the process unfair. The case underscores how late-breaking expert opinions can destabilise apparent clinical consensus, particularly when procedural safeguards (e.g., adjournments for rebuttal evidence) are denied.
The judgment needed to be focused instead on the procedural flaws (e.g., lack of adjournment, imbalance in expert evidence). The shift in the care team’s position appears to stem from forensic input (Dr Brown/Baruah). The specific rationale for their conclusions is not disclosed or analysed in the decision.
Takeaway points
This case highlights critical challenges in balancing patient autonomy with public safety in psychiatry, not just forensic psychiatry. At its core, it underscores the tension between clinical judgments and legal processes, revealing systemic vulnerabilities in risk assessment and decision-making.
The Fragility of Clinical Consensus: When managing patients with severe mental disorder and a history of serious offending, clinical teams must integrate forensic expertise with day-to-day care. Discharge decisions often hinge on a fragile consensus among clinicians, which can unravel when new evidence emerges. Late-stage shifts in expert opinions—particularly when based on forensic risk assessments not fully communicated to the patient or their representatives—risk undermining trust in the process. Such reversals highlight the need for transparent, unified evaluations that bridge clinical stability and offence-related risks.
The Unexamined Offence: A Gap in Risk Management: Reoffending while under conditional discharge is a critical indicator of unresolved risks. By dissecting new information clinicians ca further tailor interventions to address dynamic risks like impulsivity or lack of empathy.
Stability vs. Safety: The Limits of Symptom Control
While managing symptoms of mental illness is essential, stability alone does not guarantee safety. Risk assessments must weigh static factors (e.g., prior offences) against dynamic ones (e.g., coping skills, insight). Overemphasising clinical stability without addressing forensic history risks premature discharge decisions, particularly when community safeguards are untested.
The Ethics of Unchallenged Expertise: When expert opinions drive decisions, their conclusions must be open to scrutiny. Reliance on forensic assessments without allowing patients to challenge or contextualise them creates an imbalance.
Community Readiness: Theory vs. Reality – Discharge plans sometimes assume idealised community support, but practical challenges—like securing funding or trialing independence through gradual leave—can be overlooked. Without real-world testing, discharge plans risk being aspirational rather than actionable, leaving patients unprepared for the complexities of reintegration.
Procedural Fairness and Clinical Accountability: The refusal to adjourn hearings or allow patients to secure independent expertise undermines procedural fairness. Clinicians and tribunals must ensure that decisions are both legally sound and legally defensible, with clear rationales for risk assessments and discharge criteria.
