A case filed in federal court in San Antonio by two same-sex couples may ultimately be heard by the U.S. Supreme Court, according to Barry Chasnoff, the couples' attorney.

“This case may be the one that makes it to the Supreme Court,” said Chasnoff. “The issue is going to have to be decided by the Supreme Court and I think our chances are very good.”

Chasnoff has filed a motion in federal court seeking an injunction against the state of Texas claiming that the couples' constitutional rights are being violated.

The couples are identified as Cleopatra DeLeon and Nicole Dimetman, of Austin, and Victor Holmes and Mark Phariss, of Plano.

The motion alleges that the Texas' ban on same-sex marriage violates the due process and equal protection clauses of the Fourteenth Amendment of the U.S. constitution.

Chasnoff said he is hoping that oral arguments on the motion will be heard in federal court here in February of next year or March at the latest.
