Miller v. California

The basic guidelines for the trier of fact must be: (a) whether "the average person, applying contemporary community standards" would find that the work, taken as a whole, appeals to the prurient interest, (b) whether the work depicts or describes, in a patently offensive way, sexual conduct specifically defined by the applicable state law; and (c) whether the work, taken as a whole, lacks serious literary, artistic, political, or scientific value.

We emphasize that it is not our function to propose regulatory schemes for the States. That must await their concrete legislative efforts. It is possible, however, to give a few plain examples of what a state statute could define for regulation under part (b) of the standard announced in this opinion, supra: (a) Patently offensive representations or descriptions of ultimate sexual acts, normal or perverted, actual or simulated; (b) Patently offensive representations or descriptions of masturbation, excretory functions, and lewd exhibition of the genitals.
