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.

A state legislative committee has advanced a resolution asking that the power to regulate marriage be returned to the states.

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.
