Log Cabin Republicans v. United States, 658 F.3d 1162 (9th Cir. 2011) was a federal lawsuit challenging the constitutionality of 10 U.S.C. § 654, commonly known as don't ask, don't tell (DADT), which, prior to its repeal, excluded homosexuals from openly serving in the United States military. The Log Cabin Republicans (LCR), an organization composed of lesbian, gay, bisexual, and transgender (LGBT) Republicans, brought the suit on behalf of LCR members who serve or served in the military and were subject to DADT.
