Factual and Procedural Background
The case concerns an adult female ("Plaintiff") born in 1972 who suffered a hypoxic brain injury following surgery in 2010, resulting in significant amnesia and cognitive impairment. Prior to her injury, the Plaintiff had a history of chaotic lifestyle, including substance abuse and criminal convictions related to prostitution. She has three children, none of whom currently live with her.
Following her injury, the Plaintiff was placed in specialist rehabilitation and later in supported living arrangements. Proceedings before the Court of Protection were initiated by a third party ("Appellant"), who had a prior relationship with the Plaintiff and challenged restrictions imposed on his contact with her. The main issues in the proceedings were the Plaintiff’s residence, care, and contact arrangements, including her capacity to consent to sexual relations.
Declarations were made that the Plaintiff lacked capacity to make decisions concerning residence, care, and contact. The court set out a plan for her care and contact with the Appellant under supervision and safeguarding assessments. The issue of the Plaintiff's capacity to consent to sexual relations was specifically examined through expert psychiatric and neuropsychological reports, which produced differing opinions.
The matter was heard before a judge who concluded that the Plaintiff possessed capacity to consent to sexual relations in a general, issue-specific sense, though with some limitations in understanding the implications of pregnancy. The Appellant’s mother ("Appellant") appealed the decision, challenging the legal test applied and the judge’s findings.
Legal Issues Presented
- What is the appropriate legal test for determining capacity to consent to sexual relations under the Mental Capacity Act 2005?
- Is capacity to consent to sexual relations issue-specific or person/partner-specific?
- How should the ability to use and weigh relevant information be applied in assessing capacity to consent to sexual relations?
- Did the judge err in law or fact in concluding that the Plaintiff had capacity to consent to sexual relations?
- What is the correct approach to balancing personal autonomy and protective intervention in cases involving capacity to consent to sexual relations?
Arguments of the Parties
Appellant's Arguments
- Legal capacity evaluation must focus on the individual's ability to make the specific decision, considering the person’s characteristics.
- Capacity to consent to sexual relations should be person-specific, relating to a particular sexual partner.
- The existing case law on capacity to consent to sexual relations is confused and requires modification.
- On the facts, the Plaintiff lacked capacity to consent to sexual relations when considering person-specific elements.
- The judge erred by applying an incorrect threshold, considering irrelevant factors, and departing from expert evidence without adequate reasoning.
- The hearing was too brief and insufficient to fully explore expert evidence.
- The judge wrongly considered best interests issues at the capacity stage.
Respondent's Arguments (Official Solicitor and Others)
- The correct legal approach is that capacity to consent to sexual relations is issue-specific, not person-specific.
- The Appellant conflates capacity with the exercise of capacity and blurs the line between capacity and best interests.
- The Appellant’s approach demands an unrealistically high level of capacity not required in everyday life.
- The judge’s decision respects personal autonomy and is consistent with the Mental Capacity Act 2005 and relevant case law.
- It is impractical and intrusive to require capacity assessments for each potential sexual partner.
- The element of using and weighing information is of limited relevance in the context of sexual consent, which is often driven by emotion and instinct.
Local Authority's Arguments
- The Act is concerned with enabling the court to make decisions only where the individual lacks capacity.
- Decisions about sexual relations are deeply personal and sensitive; courts should be cautious before declaring incapacity.
- The decision to consent to sexual relations is typically impulsive and emotive, so stringent cognitive requirements are inappropriate.

Court's Reasoning and Analysis
The court began by acknowledging the complex and sensitive nature of assessing capacity to consent to sexual relations, emphasizing the importance of the Mental Capacity Act 2005 ("the Act") as the statutory framework. It noted the Act’s principles, including the presumption of capacity, the requirement to take all practicable steps to support decision-making, and the prohibition on equating unwise decisions with incapacity.
The court reviewed the factual background and expert evidence, noting that while the Plaintiff understood the nature of sexual intercourse and basic risks (pregnancy, sexually transmitted infections), she lacked full understanding of the consequences of pregnancy and was unlikely to take appropriate action in response to health symptoms.
Turning to the legal principles, the court examined the apparent conflict between first instance case law, which generally supports an issue-specific (act-specific) test for capacity to consent to sexual relations, and the observations of Baroness Hale in Regina v Cooper, which emphasized the person- and situation-specific nature of sexual consent in the criminal context.
The court distinguished the civil capacity assessment from criminal law, explaining that the former requires a prospective, general evaluation of capacity to consent to sexual relations, not tied to a specific partner or occasion. It held that the statutory test under s. 3(1) of the Act, which includes the ability to understand, retain, use or weigh information, and communicate a decision, applies fully to capacity to consent to sexual relations.
The court agreed with the line of authority that capacity to consent to sexual relations is issue-specific rather than person-specific and that the ability to use and weigh information, although part of the test, is less prominent in this context given the emotional and instinctual nature of sexual decisions.
The court found that the judge had correctly applied the law and reached a reasoned conclusion based on the evidence. It rejected the appellant’s criticisms that the judge took irrelevant factors into account or failed to properly consider expert evidence. The court also found no procedural unfairness in the hearing process.
Holding and Implications
The appeal is dismissed.
The court upheld the decision that the Plaintiff has capacity to consent to sexual relations on a general, issue-specific basis, despite some limitations in understanding certain consequences. The ruling affirms that capacity assessments under the Mental Capacity Act 2005 must be decision-specific and apply the full statutory test, including the ability to use and weigh information.
The decision clarifies the distinction between civil capacity assessments and criminal law consent analysis, endorsing the practicality and respect for autonomy inherent in the issue-specific approach. No new precedent was set beyond confirming and applying existing legal principles in this sensitive area. The direct effect is to maintain the status quo regarding the Plaintiff’s capacity and the related care and contact arrangements.
