The Conference is over for today; that was some time ago. What's going on now is composing orders, if any are to be released today. Simple grants are easier to write than, say, consolidated grants among several picked cases....UPDATE: "Prop. 8 is grant[d]. So is Windsor. Those are the only two marriage cases granted."
I expect the Court to act today on the gay-marriage petitions for two reasons. First, it has to rule on the petitions at this Conference if they are going to be argued in March. Otherwise, it has to wait until April. And the Court would prefer to have more time between the argument and when the Court ends the Term in late-June.
Prop. 8 is granted on the petition question -- whether 14th Am. bars Calif. from defining marriage in traditional way. Plus an added question: Whether the backers of Prop. 8 have standing in the case under Art. III.
In Windsor, the government petition (12-307) is the one granted. In addition to the petition question -- whether Sec. 3 of DOMA violates equal protection under 5th Amendment, there are two other questions: does the fact that government agreed with the 2d CA decision deprive the Court of jurisdiction to hear and decide the case, and whether BLAG (House GOP leaders) has Art. III standing in this case.AND: "The Court... has agreed to take up virtually all of the key issues about same-sex marriage, but has given itself a way to avoid final decisions on the merits issues."
