New Mexico Governor Susana Martinez on Monday stated her opposition to a constitutional amendment which would define marriage as a heterosexual union in the state.

Speaking to reporters, Martinez, a Republican, said that she won't endorse the legislation.

“I think what I said before was that yes, the people should have decided on it, but the Supreme Court has decided. And it's now the law of the land,” Martinez said.

State Senator William Sharer, also a Republican and a vocal opponent of marriage equality, introduced Joint Resolution 6 on the day after the New Mexico Supreme Court issued a ruling legalizing gay nuptials in the Land of Enchantment.

When asked specifically about Sharer's proposal, Martinez answered: “It's the law of the land. The Supreme Court has spoken.”

Sharer told outlets that a draft of the amendment was “just sitting there waiting until I said go.”

He pushed for a similar measure unsuccessfully in 2011.
