The Supreme Court has agreed to hear a case that will, in effect, decide if the Constitution requires all states to have gay marriage.
From Robert Barnes, Supreme Court agrees to hear gay marriage issue – The Washington Post:
The Supreme Court announced Friday that it will decide a historic question about whether the Constitution requires that same-sex couples be allowed to marry no matter where they live or whether states are free to limit wedlock to its traditional definition as a union only between a man and a woman.
The court accepted cases from Michigan, Ohio, Kentucky and Tennessee, where restrictions about same-sex marriage were upheld by an appeals court in Cincinnati two months ago. The high court will hold 2 1/2 hours of oral arguments in April and decide the issue by the time the current term ends in June.
