Heart of England NHS Foundation Trust v JB

Factual and Procedural Background

This case concerns a 62-year-old female patient ("Plaintiff") diagnosed with paranoid schizophrenia and multiple chronic physical health issues, including diabetic complications and peripheral vascular disease. The Plaintiff developed gangrene in her right foot, leading to medical advice recommending amputation to prevent life-threatening infection. The Plaintiff refused consent to amputation, raising concerns about her capacity to make this decision. Conflicting medical opinions emerged regarding her mental capacity to consent or refuse treatment. The healthcare Trust ("Defendant") applied to the Court of Protection for a declaration that the Plaintiff lacked capacity to decide on the amputation and sought authorization to proceed with surgery, including sedation if resisted. The Official Solicitor was appointed to represent the Plaintiff. The hearing was conducted in public over two days with evidence on capacity and submissions presented before judgment was delivered.

Legal Issues Presented

1. Whether the Plaintiff has the mental capacity to make a decision regarding consent to amputation of her right leg, considering her mental illness and physical condition.
2. Whether the Plaintiff's refusal of medical treatment constitutes a lack of capacity or an unwise decision protected by the law.
3. The appropriate application of the Mental Capacity Act 2005 principles to the Plaintiff's case.

Arguments of the Parties

Defendant's Arguments

• The Plaintiff lacks capacity to make the decision about amputation, based primarily on evidence from the community psychiatrist, Dr O.
• The Plaintiff’s mental illness (paranoid schizophrenia) impairs her ability to weigh information and make an informed decision.
• The amputation is in the Plaintiff’s best interests, and the court should authorize the procedure and sedation if necessary.
• Capacity concerns are justified by the Plaintiff’s inconsistent decisions and minimization of medical risks.

Official Solicitor's Arguments

• The Plaintiff retains capacity to make decisions about her medical treatment, supported by evidence from consultant psychiatrist Dr Pravin Prabhakaran and consultant surgeon Mr Collin.
• The Plaintiff is able to understand, retain, use, and weigh relevant information regarding the proposed surgery.
• The Plaintiff’s refusal of surgery is an expression of her autonomy and not indicative of incapacity.
• The assessment of capacity must focus on the broad understanding of the nature, purpose, and effects of treatment, not on the wisdom of the decision.

Table of Precedents Cited

Precedent	Rule or Principle Cited For	Application by the Court
In Re C (Adult: Refusal of Treatment) [1994] 1 WLR 290	Established criteria for assessing capacity to refuse medical treatment; emphasized that capacity involves understanding nature, purpose, and effects of treatment.	Used as a comparative case to illustrate that even persons with serious mental illness may retain capacity to refuse treatment; highlighted that capacity must be judged on statutory criteria, not on the perceived wisdom of the decision.

Court's Reasoning and Analysis

The court began by reaffirming the fundamental right of individuals to consent to or refuse medical treatment, emphasizing that capacity must be presumed unless proven otherwise on the balance of probabilities under the Mental Capacity Act 2005. The court outlined the statutory test for incapacity, focusing on the ability to understand, retain, use or weigh relevant information, and communicate a decision.

The court considered conflicting medical evidence regarding the Plaintiff's capacity. It noted that some clinicians viewed the Plaintiff as lacking capacity due to her mental illness and tendency to minimize risks, while others found her capable of understanding and reasoning about her treatment options despite her schizophrenia.

The court rejected assessments that equated unwise decisions or refusal of medical advice with incapacity. It emphasized that capacity assessments must not be influenced by whether a decision aligns with medical recommendations. The court found that the Plaintiff’s cognitive impairments related to schizophrenia affected how she made decisions but did not negate her capacity to decide on surgery.

The court gave significant weight to the evidence of the consultant psychiatrist and surgeon who found the Plaintiff capable of making an informed decision after detailed discussions. It held that the Plaintiff's tendency to avoid or minimize risks was a normal coping mechanism rather than evidence of incapacity.

Finally, the court concluded that the Plaintiff has capacity to decide on amputation of her leg, considering the treatment as a whole rather than focusing narrowly on specific types of amputation, thus avoiding unnecessary repeated assessments due to changing medical opinions.

Holding and Implications

The court held that the Plaintiff retains the capacity to make decisions regarding consent to amputation of her right leg, despite her diagnosis of paranoid schizophrenia and physical health challenges.

The direct effect of this decision is that the Plaintiff’s autonomy in deciding whether to undergo surgical treatment must be respected. The Plaintiff may choose to consent to or refuse the recommended below-knee amputation, and no court order authorizing the procedure without her consent will be made. No new legal precedent was established; rather, the decision reaffirmed the established principles protecting the autonomy of persons with mental illness in medical decision-making.
