DB v Humber Teaching NHS Foundation Trust & Anor (Mental Health) [2026] UKUT 57 (AAC) (05 February 2026)

Executive summary

The Upper Tribunal allowed DB’s appeal in part, held that it was legally permissible for a restricted patient to be conditionally discharged while remaining in hospital on an informal basis, set aside the First-tier Tribunal’s decision, and remitted the case for rehearing by a differently constituted panel. The tribunal decided the case without a hearing after considering the papers and the Secretary of State’s policy on recall of conditionally discharged restricted patients.

Key points

• DB was a restricted patient under sections 37 and 41 of the Mental Health Act 1983, recalled to hospital by the Secretary of State after conditional discharge.
• The First-tier Tribunal had refused discharge, reasoning that DB’s treatment could only be given if he remained detained and that informal hospital residence was not a permissible discharge option.
• Upper Tribunal Judge Jacobs held that conditional discharge while remaining voluntarily in hospital was permissible, relying on section 131 and the explanation of 'discharge' in M v Secretary of State for Justice [2019] AC 712 at [20].
• The Upper Tribunal set aside the First-tier Tribunal’s decision for error of law under section 12(2)(a) and (b)(i) of the Tribunals, Courts and Enforcement Act 2007.
• The decision noted potential implications for the Secretary of State’s policy on the recall of conditionally discharged restricted patients.
• The order was anonymised and public release was expressly directed under Rule 14(7) of the Tribunal Procedure (Upper Tribunal) Rules 2008.

Why it matters

This is a mental health and detention case, not a sanctions case, but it matters for state coercive power and policy-controlled liberty restrictions. It is relevant to sovereign-risk style analysis insofar as it addresses how the UK interprets statutory powers of detention, recall, and informal hospital residence in a sensitive public-law setting.

Implications

For compliance and litigation strategy, the decision weakens any categorical position that a restricted patient must remain formally detained to be conditionally discharged, and it opens room to argue for informal in-hospital arrangements where statutory criteria are met. It also suggests the Secretary of State’s recall policy may need to be read consistently with section 131 and the tribunal’s understanding of 'discharge', making future challenge or review of recall decisions more fact-sensitive and legally structured.
