In 2006, Idaho voters passed an amendment to the state Constitution to define marriage as a union between a man and a woman, though the Supreme Court’s ruling nearly a decade later found that such laws violate the 14th Amendment’s equal protection and due process guarantees.

GOP lawmakers in Idaho are pushing to end same-sex marriage by sending a letter to the U.S. Supreme Court asking it to overturn its landmark decision.

The memorial would call on the Supreme Court to “restore the natural definition of marriage, a union of one man and one woman."

Idaho House representatives voted Monday, 46-24, to advance "House Joint Memorial 1." In it, they write that they reject the U.S. Supreme Court's 2015 decision in "Obergefell v. Hodges" and demand that it be overturned.

Idaho House lawmakers have signed off on a resolution calling for the U.S. Supreme Court to overturn its 2015 decision legalizing same-sex marriage nationwide.
