This paper explores some of the controversies in the debate regarding the j
ustification of civil commitment. The sometimes conflicting values reflecte
d in the mental health legislation, human rights principles, moral philosop
hy and psychiatric professional standards are discussed. In spite of the of
ten substantial use of civil commitment in many countries, there are almost
no scientifically sound studies addressing the outcome of coercive treatme
nt. The paper establishes that the traditional arguments in favour of civil
commitment, like lack of insight and competence as well as the effectivene
ss of civil commitment, are poorly founded. The paper concludes that there
seems to be a general agreement that civil commitment of patients who are d
angerous to themselves or others should be the responsibility of the mental
health care system, while civil commitment for treatment purposes is more
controversial and hard to justify.
