Marquez v. Screen Actors Guild Inc.  Marquez v. Screen Actors Guild Inc., 525 U.S. 33 (1998), was a United States Supreme Court decision involving the validity of a union shop contract. The petitioner Naomi Marquez is a part-time actress who successfully auditioned for a one-line role in "Medicine Ball", a television series produced by Lakeside Productions. Pursuant to the union agreement Lakeside Productions had with the Screen Actors Guild (SAG), Lakeside contacted the SAG to verify that Marquez met the requirements of the union security clause. It turns out that Marquez had previously worked in the motion picture industry for more than 30 days, thus the union security clause was triggered and Marquez was required to pay union fees before she could work at Lakeside. The petitioner tried to negotiate with the SAG which would allow her to pay the union fees after she completed her work with Lakeside. The negotiations did not result in any compromise. On the day the part was supposed to be filmed, Marquez still had not paid her union dues and fees. Lakeside hired a different actress to fill in the part. At some point afterwards, the SAG faxed a letter to Lakeside that it had no objections to the petitioner working in the production, but it was too late for filming had already started on schedule with the replacement actress. The petitioner filed a suit against the SAG and Lakeside claiming that they had breached its duty of fair representation by negotiating and enforcing a union security clause that used language from NLRA § 8(a)(3) but did not include the Court's rulings and explanation of rights in the terms of the agreement to intentionally mislead the workers within the union. At issue was whether a union breaches its duty of fair representation by negotiating a union security clause that uses statutory language without articulating the Court's interpretation of that language. The Court unanimously denied Marquez's claim. The Court said that the statutory language incorporates all the refinements associated with the language, is a shorthand description of the worker's legal rights. The Court explained that if the petitioner's logic was used, there would be no stopping point because all contracts would have to spell out every intricacy of every term in the contract. Contracts would thus become massive, and yet there would be no real benefit from the increase in mass. The Court decided that it was perfectly reasonable for the union to use terms of art in a contract. "NLRB v. General Motors Corp.":
