The high-profile challenge brought against the collection of public-sector union fees from non-union members in California ended Tuesday as the U.S. Supreme Court denied a request to rehear the dispute.

Without comment on its final list of orders for the current term, the court denied the rehearing petition in Friedrichs v. California. The high court on March 29 split 4-4 in the case, leaving in place a ruling by the U.S. Court of Appeals for the Ninth Circuit in favor of so-called “fair share” fees paid by nonmembers. “The judgment is affirmed by an equally divided Court,” the court stated in March.
