The U.S. Supreme Court declined to hear an appeal by the California Trucking Association over the employment classification of truck drivers contracted by motor carriers. The court’s announcement was issued March 18 in the case of California Trucking Association v. Julie A. Su. The case was among numerous others labeled “Certiorari Denied” by the high court without further explanation. Under Supreme Court rules, four of the nine justices must vote to accept a case. It accepts 100-150 of the more than 7,000 cases that it is asked to review each year, according to the Administrative Office of the U.S. Courts.
