BOISE, Idaho (AP) — The federal government cannot force Idaho to change its definition of marriage as the union of one man and one woman. That's according to the conservative Cornerstone Family Council of Idaho in a recent court filing. The council rejected the idea that a recent U.S. Supreme Court decision striking down a portion of the Defense of Marriage Act required Idaho to permit same-sex marriage or recognize same-sex marriages from other states. The council contends in a brief filed last week that the Supreme Court case narrowly involved the issuance of federal benefits to same-sex couples.
