Civics GovernmentJudicial Review and the Power of Precedent
Justice stands in a grand marble courtroom holding an open copy of the Constitution, gesturing toward a towering wall of leather-bound case reporters — volumes of past Supreme Court decisions — while a projected diagram on the wall shows a law being weighed against constitutional text.
- Explain how judicial review gives courts the authority to invalidate laws that conflict with the Constitution.
- Identify the landmark case that established judicial review in the United States.
- Define precedent and describe how the doctrine of stare decisis shapes future court decisions.
- Compare situations where courts follow precedent with situations where they may overturn it.
- Predict the likely outcome of a hypothetical case by applying a relevant precedent.
Key terms
- Judicial review
- The power of courts to invalidate laws and government actions that conflict with the Constitution.
- Precedent
- A prior court ruling that guides how courts decide later cases raising the same legal question.
- Stare decisis
- The Latin doctrine of standing by things decided, creating a presumption of following precedent.
- Overruling
- A court's decision to discard its own precedent when it was wrongly decided or conditions changed.
- Separate-but-equal doctrine
- The Plessy-era rule permitting racial segregation, overruled by Brown v. Board of Education.
Two Pillars Working Together
Judicial review and precedent answer different questions that courts ask in tandem. Judicial review asks whether a challenged law squares with the Constitution, the power Marshall grounded in Marbury v. Madison and later extended to executive actions and state laws. Precedent asks what prior courts already decided on the same question, supplying continuity. Together they make courts simultaneously bound by history and responsible for constitutional development, so a sound analysis identifies both the constitutional provision at issue and the most relevant prior ruling before predicting an outcome.
When Courts Depart From Precedent
Stare decisis creates a strong presumption of stability, but it is a principle of policy, not an iron rule. The Supreme Court may overrule its own decisions when it concludes the earlier ruling was wrongly reasoned or that legal and social conditions have fundamentally shifted. Brown v. Board of Education (1954) is the defining example, discarding the separate-but-equal doctrine of Plessy v. Ferguson (1896) as incompatible with the Equal Protection Clause. Knowing both the presumption and its exceptions prevents the error of treating any precedent as permanently frozen.
Worked examples
Predict an outcome by applying precedent.
- Identify the constitutional provision at issue, here student free speech.
- Locate the controlling precedent, Tinker v. Des Moines (1969).
- Confirm the new facts closely match the precedent's protected conduct.
- Apply stare decisis to forecast the same protective result.
Answer: The court will most likely follow Tinker and uphold the student's expression.
Classify Brown overruling Plessy.
- Note Plessy established the separate-but-equal doctrine in 1896.
- Recognize Brown rejected that doctrine in 1954.
- Identify the action as discarding the Court's own prior ruling.
- Match it to overruling precedent rather than ordinary judicial review.
Answer: Brown overruling Plessy is an example of overturning precedent.
Activity
Sort each scenario card into the correct category: 'Applying Precedent,' 'Exercising Judicial Review,' or 'Overturning Precedent.'
Practice
Determine whether a court following Tinker is applying or overturning precedent and why.
Explain when the Supreme Court may legitimately depart from its own precedent.
Common mistakes to avoid
- Stare decisis makes precedent permanentThe Court may overrule precedent when it was wrongly decided or conditions have fundamentally changed.
- Striking a law down is the same as overturning precedentJudicial review voids a conflicting law, while overruling discards the Court's own earlier decision.
Check your understanding
Which case first established the principle of judicial review in the United States?
A state legislature passes a new tax law. A taxpayer argues it violates the Constitution. The court agrees and refuses to enforce the law. This is an example of which judicial power?
A student argues: 'Stare decisis means the Supreme Court can never change its mind — once a precedent is set, it is permanent law.' Which response best evaluates this claim?
A new case reaches the Supreme Court. The facts closely match a prior ruling that held a similar government action unconstitutional. Based on stare decisis, what outcome is most likely?
Recap
Judicial review, established in Marbury v. Madison, lets courts void unconstitutional laws, while stare decisis presses courts to follow precedent for predictability; yet precedent can be overruled, as Brown v. Board did to Plessy, balancing stability against constitutional development.
Reflect
When should stability through precedent give way to correcting a wrong decision?
