The United States Court of Appeals for the Third Circuit, in establishing the standards for evaluating Sherman Act jurisdictional prerequisites in denial of staff privileges cases, has rejected the imposition of any specific requirement, holding instead that allegations of a shift of interstate commerce will suffice to obtain jurisdiction, and has indicated that the Third Circuit will examine the activities of both plaintiffs and defendants in ascertaining the presence of interstate commerce.
