From the piece:
On Friday, the Supreme Court will convene privately to make a highly anticipated decision: Will it weigh in on gay marriage? There are currently seven cases in front of the court, covering issues from whether married gay veterans can be buried together in a military cemetery to whether same-sex couples can once again marry in California. The court can decide to hear all, some, or none of the cases. And merely deciding to take a case or not will have broad implications for the future of gay marriage in the United States.
Which cases are involved?
