[JURIST] After 11 states voted Tuesday for bans on gay marriage, civil rights groups wasted no time Wednesday preparing legal challenges. Karl Olson, executive director of the gay-rights group PRIDE in Montana, said that this vote was only a "blip" in history, adding that the Constitution "isn’t going to be able to sustain this kind of restriction on civil rights.” Lambda Legal Defense Fund has already announced plans to file lawsuits challenging the states' new amendments, saying that these states have in fact written anti-gay discrimination into their laws. Gay marriage proponents are not, however, optimistic on the suits' success. AP has more.
