Ware v. Hylton, 3 U.S. (3 Dall.) 199 (1796), also known as the British Debt Case, is a United States Supreme Court decision holding that treaties take precedence over state law under the U.S. Constitution. Ware was the first major 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. It 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.
