Calmat

John K. Laws (“Laws”) appeals the district court’s denial of his motion to remand to state court the lawsuit he initiated against his employer, Calmat Corporation (“Calmat”). In addition, he appeals the district court’s grant of summary judgment to Calmat. Laws argues that his right to privacy under the California State Constitution was violated by Calmat’s mandatory drug testing program. Laws argues that reversal is required because the district court erroneously found that his state law claim is preempted by section 301 of the Labor Management Relations Act (“LMRA”), 29 U.S.C. § 185 , section 3102 of the Motor Carrier Safety Act (“MCSA”), 49 U.S.C. § 3102 , and the United States Department of Transportation Regulations (“DOT regulations”) promulgated under the authority of the MCSA. We affirm the district court.
