[JURIST] Three plaintiffs supported by the Kentucky Fairness Alliance have filed a lawsuit against Kentucky's recently-approved constitutional ban on same-sex marriage on the grounds that it applies both to marriage and civil unions. The suit says that by not allowing voters to vote on the two aspects separately, the proposed ban violated constitutional provisions on how amendments are to be placed on ballots and also confused voters with misleading language. Civil rights groups in other states have plans for similar challenges. AP has more. JURIST's Paper Chase has more on challenges nationally and has continuing coverage of same-sex marriage.
