Marbury v. Madison (1803) is the Supreme Court case in which Chief Justice John Marshall established judicial review, the power of federal courts to strike down laws that violate the Constitution, making the judiciary the final word on what the Constitution means (KC-4.1.I.B).
Marbury v. Madison started as a petty political fight and ended up defining the Supreme Court's job. In his final hours as president, John Adams appointed a batch of Federalist judges (the "midnight judges") to pack the courts before Jefferson's Democratic-Republicans took over. One commission, for William Marbury, never got delivered. When Jefferson's Secretary of State, James Madison, refused to hand it over, Marbury sued, asking the Court to force delivery under the Judiciary Act of 1789.
Chief Justice John Marshall's ruling was a masterpiece of political judo. He said Marbury deserved his commission, but the section of the Judiciary Act that let him sue directly in the Supreme Court was itself unconstitutional, so the Court couldn't help him. Jefferson technically won the case, but Marshall won something far bigger. By striking down an act of Congress for the first time, the Court claimed the power of judicial review. That's the move the CED is pointing at when it says Supreme Court decisions "established the primacy of the judiciary in determining the meaning of the Constitution" (KC-4.1.I.B).
Marbury v. Madison lives primarily in Topic 4.2 (The Rise of Political Parties and the Era of Jefferson) under learning objective APUSH 4.2.A, explaining the causes and effects of policy debates in the early republic. The case is the textbook "effect" of the Federalist vs. Democratic-Republican rivalry, and it's the starting point for KC-4.1.I.B's claim that the judiciary became the final interpreter of the Constitution. It also reaches back to Topic 3.9, because judicial review filled in a gap the Constitution left open. The document created separation of powers among three branches (KC-3.2.II.C.ii) but never explicitly said who decides when a law crosses the constitutional line. Marshall answered that question. For the exam, this case is your go-to evidence for how the federal government's power grew in the early republic, and it underpins every later argument about checks and balances, from the Marshall Court's federalism rulings to 20th-century clashes over government power.

Judicial Review (Units 3-4)
Judicial review is the principle; Marbury is the case that created it. If a question asks where the Court got the power to strike down laws, the answer is Marbury, because the Constitution itself never spells that power out.
Midnight Judges (Unit 4)
Adams's last-minute Federalist appointments are the direct cause of the case. Marbury was one of those midnight judges, and the whole lawsuit exists because the party transition from Adams to Jefferson got messy.
John Marshall and the Marshall Court (Units 3-4)
Marbury was Marshall's opening move in a 35-year project of strengthening federal power. Pair it with McCulloch v. Maryland (1819) and Gibbons v. Ogden (1824) to show the Marshall Court asserting federal supremacy over the states, a favorite MCQ pairing.
Progressive Era and New Deal government power (Unit 7)
When Progressives and later New Deal policymakers called for greater government action (KC-7.1.II and KC-7.1.III), the Supreme Court got to judge whether those laws were constitutional. That gatekeeper role traces straight back to Marbury, which is why the case shows up in long-run continuity arguments about the judiciary.
Marbury v. Madison is a multiple-choice staple. Expect stems asking which case established judicial review during Jefferson's presidency, or which decisions show the Marshall Court building federal power between 1800 and 1835 (where Marbury gets paired with McCulloch v. Maryland or Gibbons v. Ogden). You need to do three things with it. First, identify it as the origin of judicial review. Second, connect it to the cause that produced it, the Federalist vs. Democratic-Republican party conflict after the election of 1800. Third, use it as evidence for the effect described in KC-4.1.I.B, the judiciary becoming the primary interpreter of the Constitution. No released FRQ has required the case by name, but it's strong evidence for LEQs and DBQs about the growth of federal power, the development of political parties, or continuity in checks and balances from the founding era through the 20th century.
Both are Marshall Court decisions that expanded federal power, but they did different jobs. Marbury (1803) established judicial review, the Court's power to strike down unconstitutional laws. McCulloch (1819) established federal supremacy over the states, upholding the national bank under implied powers and blocking Maryland from taxing it. Quick check for the exam: if the question is about the Court vs. Congress, it's Marbury; if it's about the federal government vs. the states, it's McCulloch.
Marbury v. Madison (1803) established judicial review, the Supreme Court's power to declare laws unconstitutional, which the Constitution never explicitly granted.
The case grew out of party conflict, since Adams's midnight judge appointments and Jefferson's refusal to deliver Marbury's commission set up the lawsuit.
John Marshall ruled against Marbury on technical grounds while striking down part of the Judiciary Act of 1789, sacrificing a small Federalist win to claim a huge power for the Court.
The CED frames this as Supreme Court decisions establishing 'the primacy of the judiciary in determining the meaning of the Constitution' (KC-4.1.I.B).
Marbury made the judiciary a real check on Congress and the president, turning the separation of powers created in Topic 3.9 into a working system of checks and balances.
On the exam, distinguish it from McCulloch v. Maryland, since Marbury is about the Court's power over Congress while McCulloch is about federal power over the states.
In 1803, Chief Justice John Marshall ruled that part of the Judiciary Act of 1789 was unconstitutional, the first time the Supreme Court struck down a federal law. This established judicial review, the Court's power to decide whether laws violate the Constitution.
No. Marshall said Marbury was entitled to his commission but that the Court lacked the authority to force its delivery, because the law giving the Court that authority was unconstitutional. Marbury lost his judgeship, but the Court gained judicial review.
Marbury (1803) is about the Court's power over Congress, establishing judicial review. McCulloch (1819) is about federal power over the states, upholding the national bank through implied powers. Both are Marshall Court cases that strengthened the federal government, just in different directions.
No, the Constitution never explicitly grants it. Article III creates the judiciary, but Marshall reasoned in Marbury that interpreting the Constitution is inherently the courts' job. That's why this 1803 case, not the Constitution itself, is the answer when APUSH asks where judicial review comes from.
It's the core evidence for KC-4.1.I.B in Topic 4.2, the idea that the judiciary became the primary interpreter of the Constitution. Multiple-choice questions ask you to identify it as the origin of judicial review and pair it with other Marshall Court cases like McCulloch v. Maryland to show growing federal power.
