Article I, Section 8, Clause 9 of the U.S. Constitution gives Congress the power “to constitute Tribunals inferior to the supreme Court.”1Constitution Annotated. Inferior Federal Courts That one sentence is why every federal court below the Supreme Court exists. The Constitution itself only requires one Supreme Court; every district court, appellate circuit, bankruptcy court, and specialized tribunal in the federal system was built by Congress under this clause, and Congress can reshape or eliminate those courts when it chooses.
What the Clause Does
The Framers deliberately left the shape of the federal judiciary open. Article III vests the judicial power “in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish.”2Constitution Annotated. Overview of Good Behavior Clause They could have written a permanent court system into the document. They didn’t. They handed the job to Congress through what is sometimes called the Tribunals Clause. Without legislation passed under it, no federal trial court and no federal appellate court would exist at all.
What Congress Has Built With It
Congress first used the power in the Judiciary Act of 1789, which split the country into thirteen judicial districts organized into three circuits.3Supreme Court of the United States. The Court as an Institution That early framework has grown. The federal system today includes 94 district courts and 13 courts of appeals.4United States Courts. About Federal Courts Congress continues to add or reallocate judgeships and can redraw geographic divisions based on caseload pressure and regional growth.
How the Clause Fits With Article III
Article I, Section 8, Clause 9 and Article III, Section 1 divide labor in a way that trips people up. Article III defines the scope of the federal judicial power and guarantees that judges of the courts it covers hold their positions during “good Behaviour” with salaries that cannot be reduced.2Constitution Annotated. Overview of Good Behavior Clause But Article III does not build any courts. The Tribunals Clause is what lets Congress actually create the courthouses, decide how many judges sit in each one, set their salaries, and organize the geographic map.
Put simply, Article III says what the federal judiciary can do; Article I, Section 8, Clause 9 lets Congress decide how it is built. Judges stay independent in their rulings, but the institutional existence of every court below the Supreme Court depends on congressional action.1Constitution Annotated. Inferior Federal Courts
Article I Courts and Other Legislative Tribunals
The clause also authorizes courts that sit entirely outside the Article III system. These are commonly called Article I courts or legislative courts. Congress uses them for subject areas that benefit from technical expertise or streamlined procedure, and the judges on them do not receive lifetime tenure. Instead, Congress can set fixed terms, control removal, and adjust their salaries.5Justia. U.S. Constitution Annotated – Legislative Courts
A few examples show the range:
- The U.S. Tax Court resolves disputes between taxpayers and the IRS. Its judges serve 15-year terms and the court has nationwide jurisdiction over matters from income tax deficiencies to estate tax disputes.6Office of the Law Revision Counsel. 26 USC 7443 – Membership7United States Tax Court. United States Tax Court
- The U.S. Court of Federal Claims hears monetary claims against the federal government based on the Constitution, statutes, regulations, or government contracts, along with bid protests and Fifth Amendment takings claims.8Office of the Law Revision Counsel. 28 USC 1491 – Claims Against United States Generally; Actions Involving Tennessee Valley Authority
- Courts-martial and the U.S. Court of Appeals for the Armed Forces operate under congressional authority, with judges on the appeals court serving 15-year terms.
Bankruptcy courts belong in the same family and are among the most heavily used. Every federal judicial district has one attached to it. Bankruptcy judges are appointed by the courts of appeals for 14-year terms and serve as judicial officers of the district court rather than as independent Article III judges.9Office of the Law Revision Counsel. 28 USC 152 – Appointment of Bankruptcy Judges They decide “core proceedings,” which include managing the debtor’s estate, allowing or rejecting creditor claims, avoiding fraudulent transfers, confirming reorganization plans, and ruling on whether specific debts can be discharged.10Office of the Law Revision Counsel. 28 U.S. Code 157 – Procedures For non-core disputes, the bankruptcy judge hears the case but submits proposed findings to the district judge for the final decision.
Even inside the district courts, not every judicial officer is an Article III judge. Magistrate judges, appointed by the district courts, handle a large share of the day-to-day work: preliminary criminal proceedings, most pretrial motions, settlement conferences, and full civil trials when both parties consent. High-stakes motions such as dismissals, summary judgment, injunctions, and criminal suppression motions still require an Article III district judge to make the final call; a magistrate’s ruling on those issues is a recommendation subject to fresh review on objection.11Office of the Law Revision Counsel. 28 USC 636 – Jurisdiction, Powers, and Temporary Assignment
Limits on What Congress Can Route Outside Article III
The power under the Tribunals Clause is broad, but the Supreme Court has drawn clear lines. The central question is whether a dispute involves “public rights” or private ones.
The distinction goes back to 1856. In Murray’s Lessee v. Hoboken Land & Improvement Co., the Court recognized that matters “involving public rights” could be handled outside the regular courts if Congress chose, because they arose from the government’s relationship with people subject to its authority.12Justia. Murrays Lessee v. Hoboken Land and Improvement Co., 59 U.S. 272 (1856) Tax disputes, immigration proceedings, and government contract claims fit that category.
Private disputes between individuals are different. In Stern v. Marshall (2011), the Court held that a bankruptcy court lacked constitutional authority to enter a final judgment on a state-law counterclaim between two private parties, even though a federal statute purported to authorize it. When a case involves “the most prototypical exercise of judicial power,” meaning a binding judgment on a common-law claim between private litigants, Article III requires an Article III judge to decide it.13Justia. Stern v. Marshall, 564 U.S. 462 (2011) The ruling forced bankruptcy courts to route certain claims through district court review that they had previously resolved on their own.
Congress Can Also Abolish Courts It Created
The same authority that lets Congress create lower federal courts lets it dismantle them. This is not theoretical. In 1801, Congress created sixteen new circuit judgeships. The following year, the incoming Jefferson administration pushed through the Judiciary Act of 1802, which repealed the 1801 law and abolished all sixteen positions.14Federal Judicial Center. Landmark Legislation – Judiciary Act of 1802 The ousted judges argued that good-behavior tenure under Article III protected them from removal by statute. Their objections did not prevail, and the episode established a lasting rule: Congress’s power to eliminate inferior courts it previously created is real, and it has been used.
That is the practical reach of the clause. Article III protects individual judges from being fired for their rulings, but Congress can still restructure the courts underneath them, adjust how many judges sit on each one, and decide what kinds of cases those courts are allowed to hear. Every part of the federal judiciary except the Supreme Court sits on that foundation.
