A section of the Treaty of Paris supersedes an otherwise valid Virginia statute under the Supremacy Clause. This case featured the first example of judicial nullification of a state law. Decided March 7, 1796 (argued February 6–12, 1796). Dissenting: Paterson. Topic: Federalism. Ware v. Hylton, 3 U.S. 199 (1796), also known as the British Debt Case, was a decision of the United States Supreme Court holding that treaties take precedence over state law under the U.S. Constitution. It was the first Supreme Court case concerned with treaties, the first to rule that treaty provisions were as binding as domestic U.S. law, and the first to affirm the supremacy of federal law over state law. Ware is also notable for articulating the legal doctrine that would later be known as judicial review, whereby federal courts have the authority to settle conflicts of law. Wiki link
