This will be very quick because it is just now showing up at SCOTUSblog.com (which is liveblogging the day's conference).
Certiorari has been granted (meaning the Supreme Court will hear the case) on the Prop 8 question as well as on the Windsor challenge to DOMA.
I'll be able to follow this and update for a while; then I have to have lunch and go to the doctor (at neither of which will I have web access).
With respect to Prop 8:
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 respect to Windsor
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.
