Article III vests all federal judicial power in one Supreme Court and inferior courts that Congress may create. This simple sentence establishes two things: the Supreme Court is the only court the Constitution requires, and Congress has discretion to build the federal judiciary beneath it. The result is a three-tier system: district courts for trials, courts of appeals for review, and the Supreme Court for final resolution.
Federal judges serve lifetime tenure and cannot have their salaries reduced while in office. Judicial power covers cases involving the Constitution, federal laws, treaties, disputes between states, and maritime matters. Within this jurisdiction, federal courts apply law to facts and issue enforceable judgments. The Supreme Court controls most of its docket through the certiorari process: it receives roughly 7,000 petitions annually but accepts about 70 cases, allowing it to focus on questions of national importance and circuit splits. Lower court decisions become final law if the Supreme Court denies certiorari.
The vesting clause shapes federalism and separation of powers. Because Article III grants federal courts authority over federal questions and certain categories of cases, state courts can't monopolize interpretation of federal law. Conversely, Congress hasn't created federal courts with jurisdiction over all law; state courts handle most disputes. And because federal judges have lifetime tenure, presidents can't control federal courts through replacement, though retirement vacancies become major political battles. These structural protections allow courts to develop law independently—sometimes defying political pressure.
Judicial power vesting determines whether federal or state courts decide vast categories of disputes and shapes whether courts can constrain political branches. It's the constitutional foundation for an independent judiciary.
People sometimes confuse the vesting clause with judicial review. Vesting just establishes the federal court system and grants it authority; it doesn't spell out judicial review. That power courts inferred from Article III structure.
