The usual composition of the panel varies by jurisdiction but may consist of a legal member, a medical member and a community/specialist member. The legal member may be a senior lawyer or judge (often senior counsel) and acts as the chair; the medical member may be a senior (e.g. consultant) psychiatrist and has often held clinical responsibility for detained patients before; and the community/specialist/'non-legal' member is neither a lawyer or medical doctor but has relevant qualifications (often at postgraduate level) and/or specialist experience in mental health, either as a mental health professional or a specialist layperson.
