Forensic Psychiatry, Ethics and Mental Health Law
Legal frameworks
Know the principles of mental health legislation: detention criteria, treatment without consent, appeals and tribunals, and the role of the nearest relative or nominated person. Understand fitness to plead, criminal responsibility, and diminished responsibility concepts, and the interface with capacity law.
Capacity and consent
Assess capacity using a structured approach: understand, retain, weigh, and communicate. Capacity is decision-specific and time-specific. Best interests decision-making applies when capacity is absent.
Ethics
Autonomy, beneficence, non-maleficence, justice, confidentiality and its limits, dual obligations in forensic settings, and the management of risk to others.
Traps
Equating diagnosis with incapacity; assuming detention authorises all treatment; breaching confidentiality without justification; confusing fitness to plead with capacity to consent to treatment.
Worked rule of thumb
A patient may refuse a specific treatment despite detention if they have capacity and the law does not authorise it. Always identify the legal basis for every intervention and record it.
