A Section 12 Approved Psychiatric Expert is a medical professional who has received specific training and approval under Section 12 of the Mental Health Act 1983 in the UK. This approval authorises them to carry out mental health assessments and make recommendations for compulsory admission to hospital when necessary. Typically, these experts are consultant psychiatrists or experienced doctors with specialised knowledge in diagnosing and treating mental health disorders. Their role is crucial in safeguarding patients' rights while ensuring that individuals in mental health crises receive appropriate care and treatment under the law. They work closely with other mental health professionals, including Approved Mental Health Professionals (AMHPs), to assess risk and make balanced, legally compliant decisions regarding detention and treatment.
