The purpose of this chapter is to protect the rights of forensic disability clients by regulating the use of behaviour control medication, restraint and seclusion (each a regulated behaviour control) under this Act so that the regulated behaviour control is only used—
(a) if considered necessary and the least restrictive way to protect the health and safety of clients or to protect others; and
(b) in a way that—
(i) has regard to the human rights of clients; and
(ii) aims to reduce or eliminate the need for its use; and
(iii) ensures transparency and accountability in its use.
