On Wednesday, October 6th, the NAACP Legal Defense and Educational Fund (LDF) filed a friend-of-the-court brief in the U.S. Supreme Court arguing that federal law does not prevent states from applying ordinary legal principles to invalidate contracts that ban consumers and employees from pursuing class actions.  If the Court prevents courts from reviewing class-action bans under generally applicable state law, it could severely jeopardize vigorous enforcement of our nation’s civil rights laws.
