I Doctrinal Framework

The Constitution operates in two major ways. First, it empowers government. It creates Congress, the President, and the federal judiciary; gives each branch certain powers; and establishes the relationship between the federal government and the states. Second, it limits government. Some limits are structural, such as separation of powers and federalism. Others protect individual rights, such as free speech, due process, equal protection, and protections against certain criminal procedures.

At the foundation of this system is judicial review, the power of courts to decide whether government action is consistent with the Constitution. Judicial review does not mean courts are superior to the political branches in every respect. It means that when a proper case is before a court, the court must apply the Constitution as supreme law and refuse to enforce government action that violates it.

II. Judicial Review

Judicial review is the doctrine that courts may determine the constitutionality of acts by Congress, executive officials, states, and other government actors. The Constitution is treated as higher law. Ordinary statutes, regulations, and executive actions must conform to it. When they do not, courts may declare them invalid or refuse to give them effect.

The power of judicial review is essential because a written constitution would have limited practical force if each branch could conclusively determine the scope of its own power. If Congress alone could decide whether its statutes were constitutional, constitutional limits on Congress would depend on Congress’s willingness to obey them. Judicial review supplies an independent legal check.

At the same time, judicial review is limited. Courts do not issue constitutional opinions whenever they believe government has acted unwisely. They decide actual legal disputes. They generally avoid abstract disagreements, political debates, and generalized grievances shared by the public at large. Courts also often presume that statutes are constitutional unless the challenger shows a constitutional defect.

The judicial role is therefore both powerful and restrained. Courts may invalidate democratically enacted laws, but only in the context of a proper case and under established constitutional doctrine.

III. Rule Statements and Elements

A useful rule statement for judicial review is:

That rule contains several important components.

• First, there must be government action. Constitutional limits generally restrict governmental conduct, not purely private conduct. A private employer’s decision, for example, usually does not raise a constitutional issue unless the employer is acting as the government, is performing a function traditionally reserved to the state, or is sufficiently connected to government action under state action doctrine.
• Second, there must be a constitutional conflict. It is not enough that the law is unfair, inefficient, or bad policy. The challenger must identify a constitutional provision, principle, or doctrine that the government action allegedly violates.
• Third, there must be a proper judicial setting. Courts require a live dispute between parties with concrete interests. This requirement is captured by the phrase “case or controversy.” The case-or-controversy requirement helps preserve separation of powers by preventing courts from acting like general policy supervisors.
• Fourth, the court must apply the correct constitutional standard. Some constitutional challenges are reviewed deferentially. Others receive strict scrutiny or a heightened form of review. The result often depends on the applicable standard.

IV Constitutional Structure

Constitutional law is deeply structural. The Constitution does not merely announce rights; it organizes power. Two organizing principles dominate: separation of powers and federalism.

Structural doctrines often appear in individual-rights problems. For example, a federal civil rights statute may raise questions about Congress’s enforcement powers. A state regulation affecting interstate commerce may raise dormant commerce concerns. A presidential action may raise separation-of-powers issues. Good constitutional analysis recognizes that rights and structure often overlap.

V. Separation of Powers

Separation of powers prevents concentration of governmental authority. The core concern is that one branch should not exercise the essential functions of another branch or interfere too severely with another branch’s constitutional role.

• Congress has legislative power. It may enact generally applicable rules within the scope of its enumerated powers. It may investigate, appropriate funds, regulate federal offices, and create statutory schemes. But Congress may not exercise executive power by directly controlling the execution of law outside constitutionally permitted mechanisms. Nor may Congress decide individual cases in the manner of a court.
• The President has executive power. The President enforces federal law, supervises executive officers, conducts foreign affairs within constitutional limits, and serves as Commander in Chief. But the President generally may not make domestic law unilaterally. Executive action must usually rest on constitutional authority, statutory authorization, or both.
• The judiciary has judicial power. Courts decide cases and controversies. They interpret law in the course of resolving disputes. But courts do not initiate policy programs, issue abstract advice, or supervise government merely because constitutional questions exist.

VI. Federalism

Federalism concerns the relationship between federal and state power. The federal government has only the powers granted to it by the Constitution. Congress must point to an enumerated power, such as the power to regulate interstate commerce, tax and spend, enforce certain constitutional amendments, or regulate matters connected to national governance.

States do not need an enumerated power in the same way. They possess broad police powers. A state may regulate contracts, property, criminal law, public health, zoning, education, family law, and many other matters unless the Constitution or federal law prevents it.

Federalism limits operate in several ways. Congress may exceed its enumerated powers. Federal law may preempt conflicting state law under the Supremacy Clause. State laws may improperly burden interstate commerce. States may violate individual rights protected by the Constitution. The federal government may also be restricted from commandeering state legislatures or executive officers to administer federal regulatory programs.

A strong federalism answer keeps the direction of the challenge clear. If the challenge is to a federal statute, ask whether Congress had constitutional authority. If the challenge is to a state statute, ask whether federal law or the Constitution limits the state’s otherwise broad police power.

VII. The Supremacy Principle

The Constitution is supreme law. Valid federal law is also supreme over conflicting state law. This means that when federal and state law conflict, federal law controls, provided the federal law itself is constitutional.

This principle is especially important because not every federal statute automatically defeats state law. Federal law must be validly enacted. If Congress lacks constitutional authority to enact the federal law, the federal law cannot preempt state law. But when Congress acts within its constitutional powers, states may not interfere with or contradict the federal scheme.

Preemption can be express or implied. Express preemption occurs when federal law explicitly states that it displaces state law. Implied preemption may occur when federal regulation is so pervasive that it occupies the field, or when state law conflicts with federal law by making compliance with both impossible or by obstructing federal objectives.

VIII Justiciability

Even when a constitutional issue exists, a federal court may refuse to hear the case if it is not justiciable. Justiciability doctrines enforce the case-or-controversy requirement and help maintain the proper role of courts in a constitutional system.

The major justiciability doctrines are standing, ripeness, mootness, the prohibition on advisory opinions, and the political question doctrine.

These doctrines are frequently tested because they determine whether the court may reach the merits. Students often rush into the substantive constitutional issue without first asking whether the plaintiff is entitled to be in court. On an exam, justiciability can be outcome-determinative.

IX. Standing

Standing asks whether the plaintiff is the proper party to bring the lawsuit. The plaintiff must show a concrete stake in the dispute.

Standing prevents courts from hearing generalized grievances. A citizen usually cannot sue merely because the government is allegedly violating the Constitution in a way that affects all citizens equally. The plaintiff must show a personal, concrete injury.

For example, a taxpayer generally cannot challenge a federal spending program simply because the taxpayer disagrees with how public funds are used. The injury is too generalized. By contrast, a business directly regulated by a statute usually has standing to challenge the statute because it faces concrete legal consequences.

X. Ripeness and Mootness

Ripeness

Ripeness asks whether the dispute has developed enough for judicial review. Courts avoid premature disputes based on uncertain future events. A claim is more likely to be ripe when the legal issue is fit for review and withholding review would cause hardship to the plaintiff.

A pre-enforcement challenge may be ripe if the plaintiff faces a credible threat of enforcement and must choose between complying with an allegedly unconstitutional law or risking penalties. But if the alleged injury depends on speculative future enforcement or uncertain factual developments, the case may be unripe. Ripeness often appears when a statute has been enacted but not yet enforced. The key question is whether the plaintiff faces a real and immediate dilemma or merely asks the court to predict future possibilities.

Mootness

Mootness asks whether the dispute remains live throughout litigation. A case that was once proper may become moot if events eliminate the plaintiff’s injury or make it impossible for the court to grant effective relief.

For example, if a plaintiff challenges a short-term restriction that expires before the court can decide the case, the defendant may argue that the case is moot. But there are exceptions. A dispute may remain reviewable if the injury is capable of repetition yet evading review, if the defendant voluntarily stops the challenged conduct but could resume it, or if collateral consequences remain.

Mootness is standing viewed over time. Standing asks whether the plaintiff had a sufficient stake at the beginning. Mootness asks whether that stake continues.

XI. Advisory Opinions and Political Questions

Advisory Opinions

Federal courts do not issue advisory opinions. An advisory opinion is a legal answer to an abstract question not tied to a concrete dispute between adverse parties. Courts decide cases; they do not provide general constitutional advice to the political branches or the public.

This doctrine preserves judicial legitimacy and separation of powers. If courts could issue abstract constitutional pronouncements whenever asked, they would become continuing legal advisers to the political branches. The judicial role is narrower: resolve actual disputes through binding judgments.

Political Question Doctrine

The political question doctrine applies when an issue is constitutionally committed to the political branches or lacks judicially manageable standards for resolution. Not every politically controversial issue is a political question. Courts routinely decide cases with political consequences. The doctrine applies only when the Constitution or the nature of the issue makes judicial resolution inappropriate.

Political question analysis requires care. A case is not nonjusticiable merely because it involves foreign affairs, elections, impeachment, war powers, or partisan conflict. The question is whether there is a legal standard the court can apply and whether deciding the case would improperly intrude on a coordinate branch’s constitutional responsibilities.

XIII Standards of Review as a Foundation

Although later chapters develop specific standards in detail, students should understand at the foundation that constitutional law often depends on the level of scrutiny.

A major exam skill is identifying the correct level of scrutiny. The same law may be upheld under rational basis review but invalidated under strict scrutiny. Therefore, always explain why a particular standard applies before evaluating whether the government satisfies it.

XIV. State Action

Most constitutional rights restrict government action, not purely private behavior. This principle is known as the state action requirement. If a private person excludes a speaker from a private dinner, the First Amendment usually is not implicated. If a city excludes a speaker from a public forum, constitutional limits apply.

State action can be obvious when a government agency, public school, police department, legislature, or court acts. It can be more difficult when private parties interact with government. A private party may be treated as a state actor when it performs a function traditionally and exclusively reserved to the state, when the government compels or significantly encourages the conduct, or when there is sufficiently close entwinement between the private party and the government.

On exams, always ask whether the Constitution applies to the defendant. A plaintiff suing a private actor must explain why that actor’s conduct should be attributed to the government.

XV. Bar-Style Analysis Notes

A well-organized constitutional law answer often uses the following structure:

1. Identify the challenged action and actor. State whether the challenged conduct is federal, state, local, or private conduct allegedly attributable to the state.
2. Address justiciability if the facts raise it. Discuss standing, ripeness, mootness, advisory opinions, or political question only when relevant. Do not mechanically recite every doctrine if the facts do not support them.
3. Identify the constitutional provision or structural principle. For federal power, ask what enumerated power supports the action. For state power, ask what constitutional limit applies. For rights claims, identify the protected right and the type of burden.
4. State the governing test. This may be rational basis, intermediate scrutiny, strict scrutiny, a balancing test, an anti-commandeering principle, a preemption analysis, or another doctrinal framework.
5. Apply the facts. Constitutional law rewards fact-sensitive reasoning. Explain both sides, but do not merely list arguments. Connect each fact to the elements of the doctrine.
6. Reach a conclusion. A good conclusion need not be absolute when the issue is close, but it should state the likely result and why.
