A push by the NSW Bar Association to relax sexual consent laws in the state so that a person who had an unreasonable belief their victim was consenting to sex would no longer be guilty of a crime has been branded a "dangerous" step by the peak body representing community legal centres.

The Berejiklian government commissioned a review of sexual consent laws in May following the high-profile acquittal of Luke Lazarus, who was accused of raping an 18-year old woman, Saxon Mullins, in an alleyway behind his father's Kings Cross nightclub in 2013.

"In the wake of the Lazarus case and the #MeToo movement, there have been calls for significant reform of both [sexual consent laws] ... and the criminal justice system’s treatment of sexual assault cases more broadly," the NSW Law Reform Commission said in a consultation paper released in October.

In a submission to the commission's review, the NSW Bar Association said a person "should not be liable to conviction for sexual assault in circumstances where he or she honestly believes that there is consent", even if that belief is unreasonable.
