# Miller v. California (1973) — AP Gov Definition & Exam Guide

## Definition

Miller v. California (1973) is the Supreme Court case that created the three-part "Miller test" for obscenity, holding that sexually explicit material loses First Amendment protection if it appeals to prurient interest by community standards, is patently offensive, and lacks serious literary, artistic, political, or scientific value.

## What It Is

Miller v. California (1973) answered a question the [First Amendment](/ap-gov/unit-3/first-amendment-freedom-religion/study-guide/lXt4frT3AX1P2eooW5ha "fv-autolink") doesn't settle on its own. Where does [protected speech](/ap-gov/key-terms/protected-speech "fv-autolink") end and unprotected obscenity begin? The Court's answer was the **Miller test**, a three-part standard. Material is obscene, and therefore not protected speech, if (1) the average person, applying *contemporary community standards*, would find it appeals to prurient interest, (2) it depicts sexual conduct in a patently offensive way, and (3) taken as a whole, it lacks serious literary, artistic, political, or scientific value (the "SLAPS" test, as teachers often call it).

The big move in Miller was handing power to *local* communities. Instead of one national standard for obscenity, what counts as obscene in a small rural town can differ from what counts in a major city. That makes Miller a clean example of how the Court balances individual liberty against government power to regulate, the central tension running through all of [Unit 3](/ap-gov/unit-3 "fv-autolink").

## Why It Matters

Miller lives in **Topic 3.2 (First Amendment)** within **Unit 3: Civil Liberties and Civil Rights**. The whole unit is built around one tension, and the CED's essential knowledge for 3.2 states it directly. There's an ongoing pull between government power to make law and [individual rights](/ap-gov/key-terms/individual-rights "fv-autolink"). Miller shows you exactly where that line gets drawn for speech. Free expression is broad but not absolute, and obscenity is one of the few categories the Court has placed entirely outside First Amendment protection (along with things like defamation and incitement). Miller is *not* one of the 15 required Supreme Court cases for [AP Gov](/ap-gov "fv-autolink"), so you won't be asked to brief it in a SCOTUS comparison FRQ. But it's the standard example of an unprotected speech category, which makes it perfect supporting evidence whenever a question asks about limits on free expression.

## Connections

### [Cohen v. California (1971) (Unit 3)](/ap-gov/key-terms/cohen-v-california-1971)

These two cases mark opposite sides of the line. Cohen protected a jacket reading "F*** the Draft" because offensive *political* speech is protected, while Miller carved out obscenity as unprotected. Together they show the Court distinguishing speech that's merely offensive from speech with no protected value at all.

### Lemon Test / Lemon v. Kurtzman (1971) (Unit 3)

Same era, same Burger Court, same move. When First Amendment lines get blurry, the Court invents a multi-part test. Lemon's three prongs handle the [establishment clause](/ap-gov/key-terms/establishment-clause "fv-autolink"); Miller's three prongs handle obscenity. Knowing which test goes with which clause is an easy MCQ point.

### [Clear and Present Danger (Unit 3)](/ap-gov/key-terms/clear-and-present-danger)

The [clear and present danger test](/ap-gov/key-terms/clear-and-present-danger-test "fv-autolink") (from Schenck) and the Miller test do the same job for different speech categories. Each one is a judicial formula for deciding when speech loses protection, one for dangerous speech, one for obscene material.

### [Censorship (Unit 3)](/ap-gov/key-terms/censorship)

Miller defines the narrow zone where government [censorship](/ap-gov/key-terms/censorship "fv-autolink") of expression is constitutional. Because the test uses local community standards, it also raises a federalism-flavored question of whether speech rights should vary by zip code.

## On the AP Exam

No released FRQ has used Miller v. California verbatim, and it's not on the required cases list, so don't expect a question built entirely around it. Where it shows up is in multiple-choice stems and scenario questions about the limits of free speech. A typical setup describes a local government banning explicit material and asks which standard a court would apply, or asks which category of speech is *not* protected by the First Amendment. Your job is to recognize obscenity as an unprotected category, recall the three prongs (prurient interest by community standards, patently offensive depiction, lacks serious value), and note that Miller lets standards vary community to community. On an Argument Essay about free expression, Miller works as evidence that First Amendment rights are broad but not unlimited.

## Miller v. California (1973) vs Lemon Test (Lemon v. Kurtzman, 1971)

Both are three-part First Amendment tests from the early 1970s, which is exactly why they get swapped on multiple choice. The Lemon test applies to the *establishment clause* and asks whether a law has a secular purpose, neither advances nor inhibits religion, and avoids excessive entanglement. The Miller test applies to *free speech* and decides whether sexually explicit material is obscene. Quick anchor for memory. Lemon is religion, Miller is obscenity.

## Key Takeaways

- Miller v. California (1973) created the three-part Miller test that decides when sexually explicit material is legally obscene and unprotected by the First Amendment.
- The three prongs are appeal to prurient interest under contemporary community standards, patently offensive depiction of sexual conduct, and lack of serious literary, artistic, political, or scientific value.
- Miller uses local community standards rather than a single national standard, so what counts as obscene can vary from place to place.
- Obscenity joins defamation and incitement as a category of expression the Supreme Court has placed entirely outside First Amendment protection.
- Miller is not one of the 15 required AP Gov cases, but it's the go-to example when a question asks about limits on free speech in Topic 3.2.

## FAQs

### What did Miller v. California decide?

In 1973, the Supreme Court held that obscene material is not protected by the First Amendment and created a three-part test for identifying it. Material is obscene if it appeals to prurient interest by community standards, depicts sexual conduct in a patently offensive way, and lacks serious literary, artistic, political, or scientific value.

### Is Miller v. California one of the required Supreme Court cases for AP Gov?

No. It's not on the list of 15 required cases, so you won't get a SCOTUS comparison FRQ about it. It still appears in multiple-choice questions about unprotected speech and works well as evidence in an Argument Essay on First Amendment limits.

### How is Miller v. California different from Cohen v. California?

Cohen (1971) protected offensive political speech, ruling that a jacket reading "F*** the Draft" was protected expression. Miller (1973) went the other way for obscenity, holding that sexually explicit material failing the three-part test gets no First Amendment protection at all. Offensive is protected; obscene is not.

### Did Miller v. California ban all sexually explicit material?

No. Miller only removed protection from material that fails all three prongs of the test. Explicit material with serious literary, artistic, political, or scientific value stays protected, which is why the third prong is often the deciding factor.

### What are 'contemporary community standards' in the Miller test?

It means juries judge the material by the values of their own local community rather than a single national standard. That's the part of Miller that gave local governments more room to regulate obscenity, and it's why the same material can be legal in one place and obscene in another.
