# Litigation — AP Gov Definition & Exam Guide

## Definition

In AP Gov, litigation means using lawsuits and the courts to challenge government actions, laws, or regulations, potentially getting them overturned. Because federal judges have life tenure, litigation lets individuals and interest groups change policy without winning an election or a vote in Congress.

## What It Is

Litigation is the strategy of taking the government to court. Instead of trying to change a law by electing new lawmakers or [lobbying](/ap-gov/key-terms/lobbying "fv-autolink") [Congress](/ap-gov/unit-1/principles-american-government/study-guide/BXlQvFOiaKwhntWYhgKP "fv-autolink"), you file a lawsuit arguing that an action, statute, or regulation is unconstitutional or otherwise illegal, and you ask a judge to strike it down.

This matters in [Topic 2.10](/ap-gov/unit-2/court-action/study-guide/1gI0LsgGzM2XSs3is8lT "fv-autolink") (The Court in Action) because of how the judiciary is built. Federal judges serve for life, so the courts can rule against popular opinion and against the elected branches without fearing the next election. That independence is exactly why litigation works as a strategy. The NAACP couldn't get segregation outlawed through Southern legislatures, but it could win *Brown v. Board of Education* in court. One successful case can set a judicial precedent that binds courts nationwide, which makes litigation a small-input, big-output way to make policy.

## Why It Matters

Litigation lives in [Unit 2](/ap-gov/unit-2 "fv-autolink") (Interactions Among Branches of Government), Topic 2.10, and connects directly to learning objective [AP Gov](/ap-gov "fv-autolink") 2.10.A, which asks you to explain how life tenure leads to debate about the Supreme Court's power. Here's the link. Life tenure makes the Court independent of the current political climate, so it can deliver controversial or unpopular decisions. That independence is what makes litigation attractive to groups who keep losing in the elected branches. But it also fuels the debate the CED highlights, because unelected judges overturning democratically passed laws raises the question of how much power the Court should have. Litigation also reaches forward into Unit 5, where it shows up as one of the main strategies interest groups use to influence policy.

## Connections

### [Life Tenure (Unit 2)](/ap-gov/key-terms/life-tenure)

[Life tenure](/ap-gov/key-terms/life-tenure "fv-autolink") is the reason litigation works. Judges who never face voters can rule against majority opinion, so a group with an unpopular cause can still win in court. That same independence is what sparks debates over whether the Court has too much power.

### [Brown v. Board of Education (Units 2-3)](/ap-gov/key-terms/brown-v-board-of-education)

Brown is the classic litigation success story. The NAACP couldn't beat segregation in Southern legislatures, so it sued instead and won a ruling that overturned Plessy. It's also a required case for equal protection in [Unit 3](/ap-gov/unit-3 "fv-autolink"), so it does double duty on the exam.

### [Amicus Curiae Briefs (Unit 2)](/ap-gov/key-terms/amicus-curiae-briefs)

Not every group has to file its own lawsuit. An amicus brief lets an outside group weigh in on someone else's litigation, telling the Court why the case matters beyond the two parties. Think of it as litigation's cheaper sidekick.

### [Judicial Precedent (Unit 2)](/ap-gov/key-terms/judicial-precedent)

[Precedent](/ap-gov/key-terms/precedent "fv-autolink") is the payoff of litigation. Win one case and the ruling binds future courts under stare decisis, so a single lawsuit can reshape policy nationwide instead of fixing one person's problem.

## On the AP Exam

Multiple-choice questions usually test litigation as a strategy. A stem describes a group or person who can't get what they want from Congress or a state legislature, then asks which action would best achieve their goal, and the answer involves going to court. You should also be ready for the limits of litigation. One Fiveable-style practice question describes a state refusing to enforce a Supreme Court decision and reenacting the same statute, testing whether you understand that a Court ruling doesn't automatically resolve a conflict, since the Court depends on other actors for enforcement. On the FRQ side, the 2021 SAQ built its scenario around Facebook testifying before Senate committees facing possible regulation, the kind of prompt where challenging regulation through litigation is the move you're asked to identify or explain. In a Unit 5 context, be ready to explain why a group would choose litigation over lobbying or electioneering.

## litigation vs Lobbying

Both are ways to influence policy, but they target different branches. Lobbying means persuading legislators or executive officials directly, and it works best when you have access and allies in power. Litigation means suing in court, and it works best when you've lost in the elected branches, because life-tenured judges don't answer to voters or donors. The NAACP turned to litigation precisely because lobbying segregationist legislatures was hopeless.

## Key Takeaways

- Litigation means using the courts to challenge government actions, laws, or regulations and potentially get them overturned.
- Litigation works as a strategy because life tenure makes federal judges independent of the political climate, so courts can issue unpopular rulings (LO AP Gov 2.10.A).
- Groups that lose in the elected branches turn to litigation, which is exactly how the NAACP won Brown v. Board of Education.
- A litigation win creates judicial precedent, so one case can change policy nationwide, but the Court still relies on the other branches and the states to enforce its rulings.
- On the exam, litigation appears both as a Unit 2 concept about judicial power and as a Unit 5 interest group strategy, so know it from both angles.

## FAQs

### What is litigation in AP Gov?

Litigation is the strategy of using lawsuits and the courts to challenge government actions or regulations, with the goal of getting them overturned. It's covered in Topic 2.10 (The Court in Action) and reappears in Unit 5 as an interest group tactic.

### How is litigation different from lobbying?

Lobbying targets lawmakers and executive officials through persuasion and access, while litigation targets the courts through lawsuits. Litigation is the go-to move when a group keeps losing in the elected branches, since life-tenured judges aren't swayed by elections.

### Does winning a lawsuit automatically change policy?

No. The Court has no enforcement power of its own, so its rulings depend on the executive branch, Congress, and the states to carry them out. A state can drag its feet or even reenact similar language, which is why Brown v. Board (1954) took years of follow-up enforcement to take effect.

### Why would an interest group use litigation instead of elections?

Because courts don't run on majority rule. A group too small or too unpopular to win elections can still win a constitutional argument before life-tenured judges, and one favorable precedent applies nationwide.

### Is litigation the same thing as an amicus curiae brief?

Not quite. Litigation means actually filing or fighting the lawsuit as a party. An amicus curiae ('friend of the court') brief is how an outside group influences someone else's case without being a party to it. Both are court-focused strategies, but only one puts you in the lawsuit.
