Registered Medical Practitioner (RMP) We generally use the term Registered Medical Practitioner in this text, in preference to the more common ‘doctor’, in order to avoid confusion with other professionals who may be entitled to use the latter title. Registered Medical Practitioners carrying out duties under the MHA need a licence to practise from the General Medical Council. The only exception is when they are acting solely as Medical Members of the Mental Health Tribunal, for whom registration alone is sufficient. Depending on the task, the MHA may require any Registered Medical Practitioner or a section-12-approved Registered Medical Practitioner or the Registered Medical Practitioner in charge of the case.
