Jefferson Parish Hospital District No. 2 v. Hyde, 466 U.S. 2 (1984), was a United States Supreme Court case in which the Court held the analysis of the tying issue must focus on the hospital's sale of services to its patients, rather than its contractual arrangements with the providers of anesthesiological services. In making that analysis, consideration must be given to whether petitioners are selling two separate products that may be tied together, and, if so, whether they have used their market power to force their patients to accept the tying arrangement. It set a permissive precedent in antitrust law, as some viewed tying as always anticompetitive.
