So what we regularly call the mental health Act is actually this law which outlines how and when we can detain people who are experiencing mental distress. So how does that happen? Well, the Mental Health (Compulsory Assessment and Treatment) Act 1992—which I note Dr Shane Reti mentioned is substantially an outdated piece of legislation—describes itself as, "An Act to redefine the circumstances in which and the conditions under which persons may be subjected to compulsory psychiatric assessment and treatment," The Act then goes on to define—fast forward a bit—that mental disorder occurs when someone "(a) poses a serious danger to the health or safety of that person or of others; or (b) seriously diminishes the capacity of that person to take care of himself or herself;—and mentally disordered, in relation to any such person, has a corresponding meaning."
