Business organizations, civil rights groups, and labor interests have signed on to support the U.S. Chamber of Commerce in its case against employment provisions in Oklahoma's new immigration law.

Twenty-eight different organizations filed amicus briefs in support of the Chamber in its ongoing case before the U.S. Court of Appeals for the Tenth Circuit. The organizations include the American Civil Liberties Union, Change to Win, various civil rights groups, business groups, and thirteen chambers of commerce. 

The Chamber is challenging Oklahoma's requirement that employers doing business with the state use the federal government's experimental Basic Pilot Program to verify their own workers' eligibility and that of individual independent contractors. The lawsuit also takes aim at a provision that allows discharged employees to bring discrimination claims against their employers if they can show that the employer knew or "should have known" that another employee was unauthorized.
