Odin Obeng challenges a federal statute criminalizing certain animal depictions. He argues the law reaches some protected artistic expression. The court finds the statute's legitimate applications to unprotected conduct far outweigh any marginal protected speech it might touch. Because Obeng cannot show substantial overbreadth, the law remains enforceable against him.

Odilia Okamura sues to invalidate a provision limiting certain electioneering communications. She points to possible applications that might affect issue advocacy.

Omar Olson challenges a statute restricting indecent material online. The law sweeps in substantial protected speech by adults. The court finds the prohibition reaches far beyond its legitimate goal of protecting minors. Because the overbreadth is substantial, the statute is facially invalid.
Olympia Steel contests a city ban on most outdoor signs. The ordinance prohibits numerous forms of protected commercial and noncommercial speech. The court determines the ban reaches substantially more protected expression than necessary for its traffic safety goals. The law is therefore facially invalid.
Oasis Resorts attacks a zoning ordinance restricting adult theaters. The company argues the rule could chill protected expression in some locations. The court finds the ordinance's legitimate applications to secondary effects predominate. Without evidence of substantial overbreadth, the facial challenge fails.

Overbreadth standing is unavailable for commercial speech restrictions. A challenger must show the law is unconstitutional as applied to the challenger's own speech rather than relying on facial overbreadth.

Overbreadth standing lets a litigant challenge a law even if the litigant's own speech is unprotected. This prevents the chilling of protected speech by others who might self-censor to avoid enforcement.
Supporting sources
