In the 2018 case, Janus v. AFSCME, the U.S. Supreme Court overturned one of its earlier decisions, the 1977 case, Abood v. Detroit Board of Ed. The 1977 Abood decision held that unions could deduct “agency fees” from union non-members without their consent. The Court in Janus, in a 5-4 decision, ended that practice as an unconstitutional violation of the First Amendment.
