A person lawfully deprived of liberty who is detained in a place not authorised by the relevant court order or statute has a claim in false imprisonment. The distinction between the 'nature' and 'conditions' of imprisonment is maintained: detention in an unauthorised type of place (e.g., a prison instead of a hospital) goes to the nature of imprisonment and grounds a false imprisonment claim, whereas complaints about treatment within an authorised place of detention go only to conditions. The word 'may' in s 24(1)(b) and s 27 of the Mental Health (Criminal Procedure) Act 1990 (NSW) confers power to make orders as to the terms and place of custody, but does not confer a discretion to decline to order detention at all.
