Abstract
The aim of the paper is to propose that special mental health laws be replaced by generic protection and prevention legislation. The arguments used for the detention and compulsory treatment of persons with mental illnesses are analysed, and found not to justify protection and prevention rules which apply only to persons with mental illnesses. Two separate systems of legal intervention should be established to deal with (1) all persons in need of compulsory care and (2) all persons who require to be detained for the prevention of harm to others.
