5.3 The Judicial Branch: Federal Courts & Judicial Review
Key Takeaways
- The federal court system has three main tiers: U.S. District Courts (94 trial courts with original jurisdiction), U.S. Courts of Appeals (13 circuits that review district court decisions), and the U.S. Supreme Court (9 justices, mostly appellate jurisdiction).
- Judicial review — the power to declare a law or executive action unconstitutional — is not written in the Constitution's text; it was established by the Supreme Court itself in Marbury v. Madison (1803).
- Federal judges, including Supreme Court justices, are nominated by the President and confirmed by a Senate majority vote, then serve lifetime appointments "during good Behaviour" under Article III.
- Original jurisdiction means a court hears a case for the first time; appellate jurisdiction means a court reviews a lower court's decision — the Supreme Court has limited original jurisdiction and mostly exercises appellate jurisdiction.
- Congress and the President check the judiciary through impeachment of judges, Senate confirmation of nominees, and the option to propose a constitutional amendment overriding a Supreme Court ruling.
Why the Judicial Branch Matters on the GED
The judicial branch completes the three-branch civics sequence and is tested through a specific, high-value concept: judicial review. GED passages frequently describe a law being challenged in court or a Supreme Court ruling striking down a statute, then ask you to name the power being exercised or to explain why the judiciary can override a law that Congress passed and the President signed. Understanding the federal court structure and where judicial review comes from — since it is not literally written in the Constitution — is essential for these items.
The Three-Tier Federal Court System
Article III of the Constitution establishes the Supreme Court and gives Congress the power to create lower federal courts. The resulting system has three main levels:
| Level | Number | Role | Jurisdiction |
|---|---|---|---|
| U.S. District Courts | 94 courts | Trial courts — hear evidence, witnesses, and testimony | Original jurisdiction (cases start here) |
| U.S. Courts of Appeals | 13 circuits | Review district court decisions for legal errors — no juries or witnesses | Appellate jurisdiction (reviews lower court rulings) |
| U.S. Supreme Court | 9 justices (1 Chief Justice, 8 Associate Justices) | Highest court in the nation; final word on federal constitutional questions | Mostly appellate; limited original jurisdiction (e.g., disputes between states) |
Original jurisdiction means a court is the first to hear a case — evidence and testimony are presented there. Appellate jurisdiction means a court reviews whether the law was applied correctly in a lower court's decision — no new evidence, just legal argument. A GED item might describe a case moving "from a trial court, to a circuit court, to the Supreme Court" and ask which court exercised original jurisdiction (the trial-level district court) versus appellate jurisdiction (the circuit court and Supreme Court).
Most cases that reach the Supreme Court arrive through a writ of certiorari — the Court's discretionary choice to hear an appeal, meaning the Supreme Court selects which cases it wants to review out of thousands of petitions each year, rather than being required to hear every case.
Judicial Review: A Power the Court Claimed for Itself
Judicial review is the power of federal courts — ultimately the Supreme Court — to declare a law passed by Congress, an action taken by the President, or a state law unconstitutional, making it unenforceable. This is one of the most commonly tested facts on the GED Social Studies Test:
Judicial review is not explicitly granted by the text of the Constitution. It was established by the Supreme Court's own ruling in Marbury v. Madison (1803), written by Chief Justice John Marshall. In that case, the Court ruled that a section of the Judiciary Act of 1789 conflicted with the Constitution and was therefore void — and in doing so, established that the judiciary has the authority to strike down laws that conflict with the Constitution.
This is a classic exam trap: many test-takers assume every major power of government must be spelled out word-for-word in the Constitution. Judicial review is the textbook counterexample — a power the judiciary exercises today that comes from case-law precedent (a court's own decision), not from constitutional text. If a GED passage asks "which case established the principle that courts can declare a law unconstitutional," the answer is Marbury v. Madison, not the Constitution itself.
Lifetime Appointments and Judicial Independence
Federal judges, including Supreme Court justices, are nominated by the President and confirmed by a simple majority vote of the Senate — the same confirmation process used for Cabinet secretaries. Once confirmed, Article III judges serve lifetime appointments, holding office "during good Behaviour," meaning they serve until death, retirement, or removal through impeachment — there is no fixed term and no mandatory retirement age. The purpose of lifetime tenure is judicial independence: insulating judges from short-term political pressure so they can rule on the law without fear of losing their job over an unpopular decision. GED passages sometimes ask why judges have lifetime appointments while presidents and members of Congress face regular elections — the answer centers on protecting judicial independence from political and electoral pressure.
Checks on the Judicial Branch
The judiciary is powerful but not unchecked, which reinforces the exam's core checks-and-balances theme:
- The President nominates all federal judges, shaping the judiciary's long-term composition.
- The Senate must confirm every federal judicial nominee by majority vote and can reject a nominee.
- Congress can impeach and remove federal judges (House impeaches by majority, Senate convicts by 2/3 vote) for serious misconduct — this is rare but constitutionally available.
- Congress and the states can effectively override a Supreme Court constitutional ruling only by passing a constitutional amendment (a high bar: 2/3 of both chambers of Congress, then ratification by 3/4 of the states) — courts cannot be overruled by an ordinary statute when the ruling rests on constitutional grounds.
Taken together, Sections 5.1 through 5.3 show the same structural logic from three different angles: each branch has its own defined powers (separation of powers), and each branch has specific tools to restrain the other two (checks and balances). Expect the GED to test all three branches both individually and in combination — for example, asking you to trace how a single controversial law could be challenged by all three branches in sequence: passed by Congress, enforced or vetoed by the President, and ultimately reviewed by the courts.
A Supreme Court ruling strikes down a federal law because the Court finds it conflicts with the Constitution. Which case established this power for the judiciary, and in what year?
A case is heard for the first time in a U.S. District Court, where witnesses testify and evidence is presented. What type of jurisdiction is the district court exercising?
Why do federal judges receive lifetime appointments rather than serving fixed elected terms like members of Congress?
