Arizona Gov. Jan Brewer has responded in federal court to a friend-of-the-court brief filed by Mexico and 10 other Latin American countries regarding the state's new immigration law.
In the filing Wednesday, Brewer says Mexico is interfering with a dispute in the U.S. and has other forums to issue political opinions than federal U.S. court.
The 9th U.S. Circuit Court of Appeals gave the foreign countries permission to present their viewpoints.
Brewer's lawyers told the appeals court that the opinions of foreign countries have no bearing on whether the law is constitutional.
Mexico was joined in its brief by Argentina, Bolivia, Brazil, Chile, Costa Rica, Ecuador, El Salvador, Nicaragua, Paraguay and Peru.
