WARREN Entsch will cut short his secondment to the United Nations in New York to bring a private member's bill to parliament calling for same-sex marriage, regardless of the postal vote's outcome.
The Leichhardt MP leaves for the US tomorrow for a three-month posting.
But he said he would return before the end of the final sitting week in November to bring forward a Bill that would legalise gay marriage but allow ministers to refuse to marry a couple if it was in conflict with their religion.
Mr Entsch said he would bring the legislation even if the postal survey, which he has called a "Mickey Mouse opinion poll", came out in favour of the "No" vote.
"After the opinion poll comes back, I'm putting up the marriage Bill," he said.
