UK Mental Health Law Reform: New Mental Health Act for First Time in 40 Years

Reform of the Mental Health Act 1983 — the legislation that governs the circumstances in which people can be detained and treated for mental illness without their consent — is progressing through Parliament, representing the most significant update to mental health law in England and Wales in four decades. The reforms follow years of campaigning by patient groups, clinicians and civil liberties organisations who argued that the Act was outdated, insufficiently protective of individual rights and applied in ways that reflected and reinforced racial and social inequalities in mental health services.

Among the most significant changes proposed is the removal of autism and learning disability from the grounds for detention under the Act, addressing the longstanding and widely criticised practice of detaining people with these conditions — who are not mentally ill in the psychiatric sense — in mental health facilities where inappropriate care and restrictive practices have caused documented harm. The reform responds to evidence that people with autism and learning disabilities have been disproportionately subject to long-term inpatient detention in circumstances that would not be permitted in other contexts.

The reformed Act strengthens patients’ rights to refuse certain treatments, enhances the role of nominated individuals who can advocate for detained patients, and provides for advance decision documents through which people with mental health conditions can express their preferences about treatment before a crisis occurs. These provisions address criticisms that the current Act gives insufficient weight to patient autonomy and self-determination.

Mental health professionals generally welcomed the direction of reform while raising practical concerns about implementation — particularly the resource implications of the enhanced advocacy and second-opinion requirements, and the need for alternative community-based provision to replace the inpatient beds that would no longer be available for the excluded categories.
