Proponents of Proposition 8, California's gay marriage ban, are not headed to the United States Supreme Court just yet.

According to gay weekly Metro Weekly, supporters will ask the full U.S. Court of Appeals for the Ninth Circuit to review the court's ruling that upheld a lower court's ruling declaring the 2008 voter-approved amendment unconstitutional.

Tuesday is the last day for supporters to file an en banc review, which would broaden the number of judges considering the case from 3 to 11.

Earlier this month, a Ninth Circuit panel ruled 2-1 against the ban. Writing for the majority, Judge Stephen Reinhardt said that there was no legitimate reason for the ban. However, the court did not rule on the broader question of whether gay couples have the right to marry.

The move greatly reduces the likelihood that the case will reach the Supreme Court before the November general election.

Analysts believe supporters are attempting to broaden the court's ruling to say that gay couples have a Constitutional right to marry before going to the Supreme Court. The high court is more likely to hear such a case and gay marriage advocates would also have more to lose.
