Mexico Allowed to Submit Brief on AZ Immigration Law

A federal judge ruled that Mexico's brief can be considered in the law suit pending against AZ's new immigration law. This is insane...AZ is a state in the United States of America not Mexico, the court case is filed in U.S. Federal Court not Mexico...allowing Mexico to have a say on U.S. law regarding illegal immigration from Mexico into the U.S. is ludicrous. Mexico has no right nor legal standing to be able to voice it's opinion about our laws in our courts! Mexico has tacitly allowed and supported the flow of illegals into the U.S. in violation of our territorial sovereignty.  This is nuts!
