The Supreme Court on Monday will release its first set of cases justices have declined to hear, which could end Proposition 8, California's gay marriage ban.

Should the court decline to hear an appeal in the case, the marriages of gay and lesbian couples taking place before the constitutional amendment was narrowly approved by voters in November 2008 could resume within days as the Ninth Circuit Court of Appeals' upholding of a lower court's decision against Prop 8 would be made permanent.

However, the case, Perry v. Hollingsworth, could also be added to the court's docket later in the 2012-2013 term.

Legal experts believe there is a greater probability that the justices will agree to hear one of the four cases challenging the constitutionality of the Defense of Marriage Act (DOMA), the 1996 law which bars federal agencies from recognizing the legal marriages of gay couples, than Perry.

If the court agrees to hear Perry, oral arguments would be presented in the spring, and a final decision would likely be issued by June 2013, according to the American Foundation for Equal Rights (AFER), the group formed specifically to challenge the ban.
