Section 29(2)(b) of the Criminal Code (NT) requires reasonable grounds for the accused's perception of the circumstances, importing the same requirement as the common law self-defence test in [name withheld] and [name withheld]. The Crown can disprove defensive conduct by negating either the subjective belief requirement or the reasonable perception/response requirement; it need not negative both. There is an unresolved anomaly between s 29 and s 43BD, with the latter applying a less demanding test to more serious offences including murder.
