New South Wales Consolidated ActsIf any proceedings (whether criminal or not) are brought against any police officer for anything done or purportedly done by the police officer in pursuance of an authorisation under Part 2, the police officer is not to be convicted or held liable merely because:
(a) there was an irregularity or defect in the giving of the authorisation, or
(b) the person who gave the authorisation lacked the jurisdiction to do so.
