Obscenity is a constitutionally unprotected form of speech. The test for determining whether something is ‘‘obscene’’ was established by the Supreme Court in 1973 in Miller v. California. The Miller obscenity test asks:

  • Whether the average person, applying contemporary community standards, would find that material, taken as a whole, appeals to the prurient interest,
  • whether the material depicts or describes, in a patently offensive way, sexual conduct specifically defined by law; and,
  • whether the material, taken as a whole, lacks serious literary, artistic, political, or scientific value. (This part of the test is governed by national, not community, standards.)

Pornography is not the same as obscenity. Pornography has no legal meaning; it is normally used to refer to sexually explicit material that may or may not qualify as obscene. Similarly, obscenity and indecency are not co-extensive. Decency is a standard used in the regulation of broadcast media to protect minors, and is not part of the Miller test.

The nude has historically been one of the central subjects of art, but it remains a subject of controversy and censorship in the United States. The beauty of the human body has inspired painters, photographers, sculptors and choreographers for many centuries. For hundreds of years there have been sculptures of nudes in many public spaces from Washington, D.C. to the capitals of Europe. Nevertheless, exhibition spaces frequently decide to censor artwork containing nudity so as to “protect children” from what some might think is “indecent,” or simply to avoid controversy. 

The U.S. Supreme Court has stated multiple times that simple nudity (i.e., representations of the nude body in a non-sexualized manner) is constitutionally protected expression. The cases below are a non-exhaustive list.
