title: Supreme Court of the United States text: Supreme Court of the United States The Supreme Court of the United States (sometimes colloquially referred to by the acronym SCOTUS) is the highest court in the federal judiciary of the United States. Established pursuant to Article III of the U.S. Constitution in 1789, it has original jurisdiction over a small range of cases, such as suits between two or more states, and those involving ambassadors. It also has ultimate (and largely discretionary) appellate jurisdiction over all federal court and state court cases that involve a point of federal constitutional or statutory law.

The High Court of Australia is sometimes said to have federal common law, but because all state and territorial courts are directly appealable title: Criminal law of the United States text: Criminal law of the United States Responsibility for criminal law and criminal justice in the United States is shared between the states and the federal government. The federal government and all the states rely on the following. Common law is law developed by judges through legal opinions, as opposed to statutes adopted through the legislative process or regulations issued by the executive branch. A common law crime is thus a crime which was originally defined by judges. Common law crimes no longer exist at the federal level, because of the U.S. Supreme Court's decision in "United States v.
