Lawmakers supporting the constitutional amendment that ended same-sex marriage in California are urging the state's Supreme Court to uphold the ban.

Several cases challenging Proposition 8 were put before the California Supreme Court since the ballot measure was passed in November.

"The fact is that the voters of California took appropriate and constitutional action when they approved a valid amendment codifying marriage as an institution between one man and one woman," Vincent McCarthy of the American Center for Law and Justice said.

The legal group submitted a brief to the High Court Friday, on behalf of several members of California's Congressional delegation.

Opponents say Prop 8 was unfairly enacted and violates basic constitutional rights. But the ACLJ says otherwise.

"The challenge to this amendment is legally flawed and improperly rejects the will of California voters. We're hopeful the California Supreme Court will take the action necessary to uphold this amendment and clear the way for its implementation," McCarthy added.

Other Prop 8 supporters recently filed suit against the state for releasing a list of names and locations of those who contributed money to support the gay marriage ban.

They are asking that their financial records be kept anonymous after receiving threats and being harassed when the information was posted online without their consent.
