SCOTUSblog is reporting that the Supreme Court has granted certiorari to both Hollingsworth v. Perry, the California Proposition 8 case, and United States v. Windsor, a Defense of Marriage Act challenge. The Court will hear arguments in the two cases when it reconvenes in 2013.

Lyle Denniston has a preliminary breakdown of the order on SCOTUSblog’s live blog:

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.

[With regards to United States v. Windsor]: 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 [Second Circuit] 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.

There is a good deal of complexity in the marriage orders, but the bottom line is this: the Court has offered to rule on Prop. 8 and on DOMA Section 3, but it also has given itself a way not to decide either case. That probably depends upon how eager the Justices are to get to the merits; if they are having trouble getting to 5 [justices] on the merits, they may just opt out through one of the procedural devices they have offered up as potentials.
