NSW Premier Dominic Perrottett will be referred to police after a minor party questioned whether he breached the law by not declaring his Nazi costume incident when he joined the Liberal party.
Mr Perrottet on Sunday sought to draw a line under the controversy and again apologised for his actions, after admitting on Thursday he wore a Nazi costume to his 21st birthday party.
NSW Shooters, Fishers and Farmers party leader Robert Borsak wants to know if Mr Perrottet broke the Oaths Act by declaring on a Liberal Party preselection document around 2010 that he had nothing to disclose that could embarrass the party.
