Lambda Legal today filed a friend-of-the-court brief urging the U.S. Ninth Circuit Court of Appeals to leave in place pending appeal the injunction a federal district court judge issued against enforcement of the U.S. military's "Don't Ask Don't Tell" (DADT) ban on gays serving openly in the armed forces, saying that the policy's impact extends far beyond those in uniform and that continuing it would do irreparable harm to lesbian, gay and bisexual Americans.
