Abstract
The aim of this chapter is to describe a type of law governing involuntary treatment that is based on decision-making capability and not on risk of harm to self or others. It is consistent with the legal and ethical principles followed in general medicine, and non-discriminatory against people with a mental illness. The rationale behind the proposal is outlined, as well as its principles and main features. It is argued that this type of law could be adapted to the needs of low and middle-income countries without sacrificing its underlying principles, and that it lends itself to such adaptation much better than traditional mental health legislation.
