Munjaz v Mersey Care National Health Service Trust & Ors

Factual and Procedural Background

Two appeals concern the use of seclusion in psychiatric hospitals. The Appellant in the first appeal challenges the lawfulness of the seclusion policy at Company A (Ashworth Special Hospital). The Appellant in the second appeal challenges the lawfulness of seclusion used in his case by Company B (Airedale General Hospital). The Secretary of State for Health was joined as an interested party in both appeals, and a mental health charity was permitted to intervene. The Mental Health Act Commission was also joined as an interested party in the first appeal and submitted evidence.

The appeals revolve around the interpretation and application of the Code of Practice issued under section 118 of the Mental Health Act 1983, particularly regarding seclusion policies and practices at the respective hospitals. The first Appellant challenges the policy’s departure from the Code, especially concerning the frequency of medical reviews. The second Appellant challenges the lawfulness of his seclusion under the Code and human rights law.

The procedural history includes judicial review proceedings and prior rulings, notably a declaration that the policy at Company A was unlawful for insufficient medical reviews and lack of independent nursing reviews. Subsequent policy revisions were made but challenged again. The second appeal arose from a challenge to the lawfulness of seclusion lasting twelve days at Company B, including issues related to transfer to a secure unit and adequacy of seclusion justification.

Legal Issues Presented

1. What is the source of domestic law justification for the use of seclusion in psychiatric hospitals, and is seclusion medical treatment under the Mental Health Act 1983?
2. What criteria determine the lawfulness of decisions to initiate or continue seclusion?
3. Under what circumstances does seclusion amount to a tortious act?
4. When does seclusion breach the patient's rights under Article 3 (prohibition of inhuman or degrading treatment) of the European Convention on Human Rights (ECHR)?
5. When does seclusion breach the patient's rights under Article 8 (right to respect for private life) of the ECHR?
6. Are there circumstances where seclusion breaches Article 5 (right to liberty and security) of the ECHR?
7. What is the status and legal effect of the Code of Practice, and under what circumstances may hospitals depart from it?
8. What remedies are available if a hospital unlawfully departs from the Code of Practice?
9. Does issue estoppel apply to prevent re-litigation of the lawfulness of hospital seclusion policies following prior judicial declarations?

Arguments of the Parties

Appellant in the First Appeal (Company A Policy Challenge)

• The hospital’s seclusion policy departs significantly from the Code, especially by reducing medical reviews after initial seclusion periods.
• The policy unlawfully treats patients as secluded based on arbitrary time periods rather than the Code’s definition, justifying less frequent reviews.
• The Code should have a strong safeguarding role to prevent breaches of patients’ human rights under the ECHR.
• The hospital’s policy fails to provide adequate safeguards consistent with the Code and human rights obligations.
• Issue estoppel should prevent the hospital from defending a new policy that conflicts with a prior judicial declaration of unlawfulness.

Appellant in the Second Appeal (Individual Seclusion Challenge)

• Seclusion was used beyond necessity and proportionate response to the risk posed.
• Seclusion was used as a means of detaining the patient in the absence of secure facilities, not for treatment or safety.
• The hospital failed to justify the continuation of seclusion after initial periods, especially night-time seclusion after 28 July.
• Seclusion interfered with residual liberty rights and should be challengeable under Article 5 of the ECHR.
• Seclusion should comply strictly with the Code of Practice to meet legal and human rights standards.

Respondents (Hospitals and Secretary of State)

• Seclusion is an implied power flowing from the statutory power to detain and can constitute medical treatment.
• The Code of Practice is guidance and hospitals may depart from it if justified by good reasons related to particular patient populations.
• For long-term secluded patients, frequent medical reviews are impractical and unnecessary; policy adjustments reflect clinical realities and resource constraints.
• Seclusion in the second appeal was a responsible and necessary measure given the lack of secure beds and the patient’s behaviour.
• The hospital’s policy and decisions did not breach Articles 3, 5, or 8 of the ECHR.
• The Secretary of State supports local decision-making by hospitals and does not consider departures from the Code inherently unlawful.

Interveners and Interested Parties

• The Mental Health Act Commission maintains that any departure from the Code’s guidance on seclusion is unacceptable and undermines patient safeguards.
• The mental health charity emphasizes the Code’s role in protecting patients’ human rights and ensuring lawful, justified use of seclusion.

Court's Reasoning and Analysis

The court analyzed the statutory and common law basis for seclusion, concluding it is an implied power flowing from the statutory power to detain patients and can constitute medical treatment under the Mental Health Act 1983. The broad statutory definition of medical treatment includes care and nursing under medical supervision, encompassing seclusion in appropriate circumstances.

The court emphasized that seclusion, while a control measure, must meet the criteria of reasonable necessity and proportionality. It rejected the notion that any departure from the Code of Practice is unlawful but held that departures require good reasons related to individual patient circumstances or well-defined patient groups.

Regarding human rights, the court accepted that seclusion can engage Articles 3, 5, and 8 of the ECHR. Article 3 sets a high threshold for inhuman or degrading treatment, requiring an assessment of severity and vulnerability. Article 8 protects private life and personal autonomy, mandating that interference be lawful, legitimate, and necessary. Article 5 concerns lawful deprivation of liberty and does not generally extend to conditions of detention but to the detention itself.

The court found that the Code of Practice serves an important role in ensuring compliance with human rights obligations, providing transparency and predictability. Hospitals must have regard to the Code and adhere to it unless there is a good reason to depart. The court rejected a purely discretionary approach allowing arbitrary departures without justification.

In the first appeal, the court held that Company A’s policy unlawfully departed from the Code by treating patients as secluded on arbitrary time-based criteria and reducing safeguards accordingly. However, the court recognized that individual departures may be justified with good reasons.

In the second appeal, the court found that the seclusion of the individual was initially justified due to risk and lack of secure facilities but that continued seclusion, especially night-time seclusion after 28 July, was not adequately justified and thus unlawful. The court noted the absence of evidence to establish a breach of Article 5 or false imprisonment but acknowledged potential interference with Article 8 rights.

The court also addressed issue estoppel, concluding that it is generally inapplicable in judicial review proceedings due to the public interest in allowing reconsideration of policies. Thus, prior declarations do not prevent hospitals from defending new policies, though good reasons must be shown for departures.

Holding and Implications

The court allowed both appeals.

In the first appeal, the court held that Company A’s seclusion policy was unlawful because it departed from the Code of Practice on an arbitrary basis, failing to apply the Code’s safeguards to all patients meeting the Code’s definition of seclusion. The hospital must apply the Code unless good reasons exist for individual departures.

In the second appeal, the court found that the continuation of the Appellant’s seclusion beyond the period justified by clinical need and risk was unlawful. The hospital failed to justify night-time seclusion after 28 July. However, there was no finding of breach of Article 5 or false imprisonment, and no claim for damages was made or established under Article 8 despite potential interference.

The court emphasized that the Code of Practice carries significant weight in protecting patients’ human rights and that departures must be justified by good reasons, not arbitrary policies. The ruling reinforces the importance of adherence to the Code to safeguard detained psychiatric patients’ rights under domestic and human rights law.

The immediate consequence is that hospitals must review and amend seclusion policies to comply with the Code, ensuring adequate safeguards and medical reviews. No new precedent was set beyond clarifying the legal status of seclusion, the Code, and the application of human rights principles in this context.
