U.S. Chamber files cert. petition regarding federal preemption of state labor law

January 09, 2008

NCLC challenged a Ninth Circuit decision holding that a California law prohibiting employers who receive more than $10,000 in state funds annually from using those funds “to assist, promote, or deter union organizing” was not preempted by the National Labor Relations Act (NLRA). A federal district court ruled in September 2002 that certain provisions of the California law were preempted by the NLRA; a three judge appeals court panel unanimously agreed in April 2004; the panel again supported preemption in a 2-1 ruling in September 2005, but was reversed by the full Ninth Circuit in September 2006.
