Judicial review is the power of federal courts to declare laws, executive actions, and state actions unconstitutional. Established in Marbury v. Madison (1803) and defended in Federalist No. 78, it makes the judiciary an equal check on the other branches (AP Gov 2.8.A).
Judicial review is the courts' power to look at a law or government action, hold it up against the Constitution, and void it if the two conflict. Here's the twist the AP exam loves: this power isn't actually written in the Constitution. Article III creates the judicial branch, and Federalist No. 78 (a required document) argues for an independent judiciary, but the Supreme Court gave itself the power of judicial review in Marbury v. Madison (1803), a required case. Chief Justice John Marshall reasoned that if the Constitution is the supreme law, somebody has to enforce it against ordinary laws, and that somebody is the courts.
Judicial review is what turns the judiciary from the "least dangerous branch" (Hamilton's phrase in Federalist No. 78, since courts have "neither force nor will, merely judgment") into a real player in checks and balances. It applies to Congress, the president, the bureaucracy, and state governments. But it also sparks a permanent debate covered in Topic 2.11. How aggressively should unelected, life-tenured judges use this power? That tension between judicial activism and judicial restraint is core CED content.
Judicial review is the centerpiece of Topic 2.8 (The Judicial Branch) and learning objective AP Gov 2.8.A, which asks you to explain the principle and how it checks the other branches using Article III and Federalist No. 78. But it doesn't stay in one topic. It's the judiciary's contribution to checks and balances in Topic 1.6 (AP Gov 1.6.A), it drives the activism-vs-restraint debate in Topic 2.11 (AP Gov 2.11.A), it's how courts hold the bureaucracy accountable in Topics 2.13-2.15, and it's the engine behind every required Supreme Court case you study, from federalism rulings in Topic 1.8 to civil rights cases in Unit 3. If you understand judicial review, you understand why Supreme Court cases are policy events, not just legal trivia.

Marbury v. Madison (Unit 2)
This 1803 required case is where judicial review comes from. Marshall declined to give Marbury his commission but, in doing so, claimed the much bigger prize of the Court's power to strike down acts of Congress. Every other required case relies on the power Marbury established.
Federalist No. 78 and Article III (Units 1-2)
The CED pairs these two documents as the foundation of judicial power (AP Gov 2.8.A). Article III sets up the courts with life tenure, and Hamilton's Federalist No. 78 argues that an independent judiciary must be able to void unconstitutional laws. Marbury basically put Hamilton's argument into practice.
Checks on the Judicial Branch (Unit 2)
Judicial review cuts both ways. Topic 2.11 covers how the other branches push back: Congress can rewrite laws or strip appellate jurisdiction, amendments can override rulings, presidents reshape the Court through appointments, and implementation can be delayed. FDR's court-packing plan is the classic illustrative example.
Constitutional Interpretations of Federalism (Unit 1)
Judicial review is the tool the Court uses to redraw the line between national and state power. When the Court interprets the Commerce Clause or the Fourteenth Amendment broadly or narrowly (AP Gov 1.8.A), it's exercising judicial review over the federal balance itself.
Affirmative Action and Civil Rights (Unit 3)
Cases like Bakke (1978) and Grutter v. Bollinger (2003) are judicial review in action on the Equal Protection Clause. Unit 3 is largely a study of how courts use this power to expand, limit, or redefine civil liberties and civil rights.
Multiple choice questions test whether you know where judicial review comes from (Marbury, not the constitutional text), what documents support it (Article III, Federalist No. 78), and how it fits into separation of powers. A question like the one on INS v. Chadha (1983), where the Court struck down the legislative veto, is judicial review enforcing separation of powers on Congress itself. On the FRQ side, judicial review shows up in the SCOTUS Comparison question (Question 3), where you connect a non-required case to a required one like Marbury, and in the Argument Essay, where Federalist No. 78 is a usable required document. The 2018 SAQ on majority opinion and policy is a good model too, since judicial review is the textbook example of a counter-majoritarian check. You should be able to define the power, name its source, give an example of the Court using it, and explain one way another branch can respond.
Judicial review is the power itself; judicial activism is one philosophy about how to use it. Activism says courts should be willing to overturn precedent and strike down legislative or executive acts, while judicial restraint says courts should stick closely to existing precedent and defer to elected branches. Both activist and restrained judges exercise judicial review. The AP Gov 2.11.A learning objective tests this exact distinction, so don't say a court 'used judicial activism' when you mean it 'exercised judicial review.'
Judicial review is the power of courts to declare laws and executive actions unconstitutional, established by Marbury v. Madison in 1803, not by the text of the Constitution.
Article III of the Constitution and Federalist No. 78 are the two documents the CED names as the foundation for judicial power and judicial independence (AP Gov 2.8.A).
Judicial review makes the courts a real check on Congress, the president, the bureaucracy, and the states, completing the system of checks and balances from Topic 1.6.
Judicial activism and judicial restraint are competing views on how boldly courts should use judicial review, not separate powers (AP Gov 2.11.A).
The other branches can limit judicial review through new legislation, constitutional amendments, judicial appointments, slow implementation, and jurisdiction stripping (AP Gov 2.11.B).
Judicial review is counter-majoritarian by design, which is why unelected, life-tenured judges can block policies that majorities support.
Judicial review is the power of federal courts to examine laws and government actions and strike them down if they violate the Constitution. It was established in Marbury v. Madison (1803) and is the core of Topic 2.8 and learning objective AP Gov 2.8.A.
No, not explicitly. Article III creates the federal judiciary but never mentions judicial review. Chief Justice John Marshall established the power in Marbury v. Madison (1803), building on the logic Hamilton laid out in Federalist No. 78. The exam loves testing this distinction.
Judicial review is the power to strike down unconstitutional acts; judicial activism is a philosophy that judges should use that power boldly, even overturning precedent. Its opposite, judicial restraint, says judges should defer to precedent and elected branches. Both philosophies still use judicial review.
Because it's where the power came from. In 1803, the Court struck down part of the Judiciary Act of 1789, marking the first time it voided an act of Congress. Marbury is a required Supreme Court case, and it's the go-to comparison case for the SCOTUS FRQ when judicial power is the issue.
Not the power itself, but they can respond to specific rulings. The CED (AP Gov 2.11.B) lists new legislation, constitutional amendments, judicial appointments that shift the Court's ideology, delayed implementation, and stripping the Court's appellate jurisdiction. FDR's 1937 court-packing plan is the famous attempted check.
