Tax Court. In certain types of cases, Article III courts may exercise appellate jurisdiction over Article I courts. In Murray's Lessee v. Hoboken Land & Improvement Co. (), the Court held that "there are legal matters, involving public rights, which may be presented in such form that the judicial power is capable of acting on them," and which are susceptible to review by an Article III court. Later, in Ex parte Bakelite Corp. (), the Court declared that Article I courts "may be created as special tribunals to examine and determine various matters, arising between the government and others, which from their nature do not require judicial determination and yet are susceptible of it." Other cases, such as bankruptcy cases, have been held not to involve judicial determination, and may therefore go before Article I courts. Similarly, several courts in the District of Columbia, which is under the exclusive jurisdiction of the Congress, are Article I courts rather than Article III courts.

Johnson in 1966. This transformed the article IV United States territorial court in Puerto Rico, created in 1900, to an Article III federal judicial district court. The Judicial Procedures Reform Bill of 1937, frequently called the court-packing plan, was a legislative initiative to add more justices to the Supreme Court proposed by President Franklin D. Roosevelt shortly after his victory in the 1936 presidential election. Although the bill aimed generally to overhaul and modernize the entire federal court system, its central and most controversial provision would have granted the President power to appoint an additional justice to the Supreme Court for every incumbent justice over the age of 70, up to a maximum of six. The Constitution is silent when it comes to judges of courts which have been abolished. The Judiciary Act of 1801 increased the number of courts to permit Federalist President John Adams to appoint a number of Federalist judges before Thomas Jefferson took office. When Jefferson became President, the Congress abolished several of these courts and made no provision for the judges of those courts. The Judicial Code of 1911 abolished circuit riding and transferred the circuit courts authority and jurisdiction to the district courts. Clause 2: Tenure The Constitution provides
