CHEYENNE, Wyo. (AP) - Wyoming, Florida and eight other states have filed a gay marriage opposition brief to a federal appeals court in California.
      
The amicus brief sent Friday to the 9th Circuit U.S. Court of Appeals says that the Constitution does not require marriage to include same-sex couples. It also says that states, not federal courts, have final say in whether to allow same-sex marriages.
      
A federal judge ruled last month that that California's Proposition 8, a voter-passed ban on same-sex marriage, was unconstitutional. The Perry v. Schwarzenegger case is on appeal.

The Casper Star-Tribune reports that other states joining the brief are Alabama, Florida, Idaho, Indiana, Louisiana, Michigan, South Carolina, Utah and Virginia.
