Larkin v. Grendel's Den, Inc., 459 U.S. 116 (1982), was a United States Supreme Court case dealing with the enforcement of liquor laws by a non-government entity.[1] Grendel's Den, a restaurant in Cambridge, Massachusetts, opened in 1971 and became a popular spot for students and professors of nearby Harvard University.[2] The owners appealed to the ABCC, addressing that numerous other establishments within the 500-ft range of Holy Cross Church had successfully received licenses.The judge used a three-pronged test that the Supreme Court had previously established in Everson v. Board of Education (330 U.S. 1 (1947)) and later enumerated in Lemon v. Kurtzman (403 U.S. 602 (1971)).The restaurant owners requested an en banc hearing at the First Circuit, and the full panel of judges reversed the three-panel decision, again ruling that Section 13C violated the Establishment Clause.
