289. Prevention of infectious diseases and persons of unsound mind, alcoholics, drug addicts and vagrants.

A person may be deprived of his liberty1 if he is lawfully2 detained for the purposes of preventing the spreading of infectious diseases or if he is of unsound mind, an alcoholic or drug addict or a vagrant3. The common thread running through the various circumstances covered by this permitted ground of detention is that deprivation of liberty may be justified on medical and social policy grounds and by considerations of public safety and the detainee's own interests4.
