Which case is cited as the business purpose doctrine: Gregory v. Helvering or Ableman v. Booth?
Ableman v. Booth Ableman v. Booth, 62 U.S. 506 (1859) , was a United States Supreme Court case in which the Court held that State courts cannot issue rulings on federal law that contradict the decisions of federal courts, overturning a decision by the Supreme Court of Wisconsin. The Supreme Court held that under the Constitution, the federal courts have the final power to decide cases arising under the Constitution and federal statutes, and that the States do not have the power to overturn those decisions. Thus, Wisconsin did not have the authority to nullify federal judgments or statutes.
FTC v. Actavis, Inc. FTC v. Actavis, Inc., 570 U.S. ___, 133 S. Ct. 2223 (2013), was a United States Supreme Court decision in which the Court held that the FTC could make an antitrust challenge under the rule of reason against a so-called pay-for-delay agreement, also referred to as a reverse payment patent settlement. Such an agreement is one in which a drug patentee pays another company, ordinarily a generic drug manufacturer, to stay out of the market, thus avoiding generic competition and a challenge to patent validity. The FTC sought to establish a rule that such agreements were presumptively illegal, but the Court ruled only that the FTC could bring a case under more general antitrust principles permitting a defendant to assert justifications for its actions under the rule of reason.
