Module 1: Judicial Review & Justiciability

Marbury v. Madison established the foundational power of federal courts: judicial review — the authority to review the constitutionality of legislative and executive acts, and to refuse to enforce those found unconstitutional. Nothing in this module means anything without this starting premise: courts genuinely have the power to say what a statute or executive action fails to comply with the Constitution.

Marbury v. Madison, 5 U.S. (1 Cranch) 137 (1803), arose from an unusually mundane dispute: outgoing President John Adams had signed William Marbury’s commission as a justice of the peace, but it was never delivered before Thomas Jefferson took office, and Jefferson’s administration simply withheld it. Marbury sued directly in the Supreme Court for an order compelling delivery. Chief Justice Marshall’s opinion is remembered less for who won (Marbury didn’t) than for how the Court got there: it held that the specific statute letting Marbury sue directly in the Supreme Court was itself unconstitutional, and in reaching that conclusion, the Court asserted — for the first time — that it has the real power to declare an act of Congress void when it conflicts with the Constitution.

Example. If Congress passes a law that a court determines conflicts with the Constitution, the court can simply refuse to enforce that law in the case before it — this is judicial review in action, the bedrock power every other doctrine in this course ultimately rests on.

Article III limits federal judicial power to actual cases and controversies — real, live disputes between real parties. Federal courts cannot issue advisory opinions on hypothetical future laws or abstract legal questions, however important or interesting.

Example. Peter asks a federal court to simply weigh in on whether a proposed (not yet enacted) bill would be constitutional if passed, with no actual dispute or real parties involved — the court has to decline. There’s no case or controversy here, just an abstract legal question, which Article III doesn’t empower federal courts to answer in the abstract.

The rule’s origin predates even Marbury. In 1793, President Washington, through Secretary of State Thomas Jefferson, asked the Supreme Court’s own Justices for their legal opinion on a set of questions about U.S. neutrality obligations during the war between Britain and France. Chief Justice Jay and the other Justices formally declined — pointing to the Constitution’s own separation of the three branches, and the fact that they sit as “a court in the last resort” meant to decide real litigation, not to advise the executive. That 1793 refusal, though never an official court opinion, is still cited today as the real historical source of the rule against advisory opinions.

Standing requires three things: injury in fact (a concrete, particularized harm, actual or imminent — not a generalized grievance shared by the public), causation (fairly traceable to this defendant’s conduct), and redressability (a favorable decision would likely address the injury).

Example. Peter sues John’s factory claiming its pollution harms “the environment generally” — too generalized, likely no standing. Now compare: Peter shows the pollution has specifically reduced fish populations exactly where he personally fishes every week — a concrete, particularized harm to his own actual use of the resource, satisfying injury in fact. If a court order stopping the discharges would likely let the fish population recover, causation and redressability are satisfied too.

Lujan v. Defenders of Wildlife, 504 U.S. 555 (1992), is the modern source of this exact three-part test. Environmental groups challenged a federal regulation limiting the Endangered Species Act’s reach to actions inside the U.S., arguing their members intended to travel abroad again “someday” to observe endangered species that might be harmed. The Court, in an opinion by Justice Scalia, held that was not enough — a vague, undated intent to return at some point in the future is exactly the kind of speculative, non-imminent harm injury in fact is meant to screen out, regardless of how genuinely the members meant it.

A claim isn’t ready for review if the harm is too speculative — courts weigh the fitness of the issue for decision against the hardship to the parties of withholding review. Genuine, immediate hardship (like a costly compliance dilemma right now) can make a pre-enforcement claim ripe even before actual enforcement occurs.

Example. Peter wants to challenge a new regulation based purely on speculation it might someday apply to him — not ripe, too speculative. Now compare: the regulation requires Peter to make an expensive, difficult business decision right now, with real consequences either way — that concrete, present hardship can make the claim ripe even though formal enforcement is still years away.

This is exactly the real test from Abbott Laboratories v. Gardner, 387 U.S. 136 (1967) — drug manufacturers sued to block an FDA rule requiring a drug’s generic name on all printed material, before the rule ever took effect. The Court held the claim was ripe: the legal issue was fit for decision (a clean question of the agency’s authority, not needing more facts to develop), and forcing the companies to wait would mean either an expensive, immediate overhaul of their labeling and marketing, or risking real penalties for noncompliance later — a genuine present dilemma, not a hypothetical future one.

A case becomes moot when the live controversy resolves itself, leaving no meaningful relief for a court to grant. Real exceptions exist: voluntary cessation (a defendant’s voluntary stop doesn’t automatically moot a case unless the conduct clearly won’t recur) and capable of repetition, yet evading review (for harms inherently too short-lived to be fully litigated before recurring).

Example. Mid-lawsuit, John’s factory voluntarily stops its discharges and asks the court to dismiss as moot. The court shouldn’t automatically agree — under voluntary cessation, a strategic pause designed to defeat the lawsuit, followed by a likely resumption, doesn’t moot the case just because the challenged conduct has technically stopped for now.

The “capable of repetition, yet evading review” exception has its own classic real illustration: Roe v. Wade, 410 U.S. 113 (1973), was already technically moot by the time it reached the Supreme Court, since the plaintiff was no longer pregnant. The Court refused to dismiss it anyway — a normal pregnancy simply doesn’t last long enough for a case to work through the full trial-and-appeal process before it naturally ends, so any pregnancy-related claim would always become moot before real appellate review could happen, unless courts recognized an exception exactly like this one.

Some issues are non-justiciable political questions, committed to Congress and the President rather than suitable for judicial resolution. Classic factors include a textually demonstrable constitutional commitment to another branch, and a lack of judicially manageable standards to apply.

Baker v. Carr, 369 U.S. 186 (1962), is the real source of the modern six-factor test (this module focuses on the two most heavily tested factors above). A Tennessee voter argued the state’s legislative districts, unchanged for decades despite real population shifts, diluted his vote in violation of equal protection — Tennessee argued redistricting was a political question courts couldn’t touch. The Court disagreed: an equal protection challenge to malapportioned districts had real, judicially manageable legal standards to apply, so it wasn’t committed to the political branches after all — opening the door to federal court review of redistricting for the first time.

Example. A plaintiff asks a federal court to decide whether the President’s decision to recognize a particular foreign government was wise — an area the Constitution commits to the political branches, with no clear legal standard for a court to apply. A court would likely dismiss this as a non-justiciable political question, not because the issue doesn’t matter, but because it’s not the kind of dispute courts are equipped or authorized to resolve.

The Supremacy Clause establishes that validly enacted federal law is supreme over conflicting state law — the constitutional foundation for federal preemption doctrine, and part of why judicial review over both federal and state action matters.

Cooper v. Aaron, 358 U.S. 1 (1958), shows how far this really reaches. After Brown v. Board of Education, Arkansas’s governor and legislature resisted desegregating Little Rock’s Central High School, arguing they were never actually parties to Brown and so weren’t bound by it. A unanimous Court — every Justice individually signing the opinion, a genuinely rare step — rejected that outright: under the Supremacy Clause, the Constitution as the Supreme Court interprets it is the supreme law of the land, binding on every state official, whether or not that official was ever a party to the specific case that established the rule.

Example. A state law directly conflicts with a validly enacted federal law addressing the exact same subject. Under the Supremacy Clause, the federal law controls — the state law must yield to the extent of the actual conflict.
