Private Adult Conduct Protected
Sean Steele and Samuel Soto engaged in intimate acts inside Taylor's apartment after work hours with no commercial element or public display. State prosecutors sought to enforce an unused statute against the conduct. The absence of any legitimate governmental objective beyond moral disapproval prevented criminal liability.
Child Pornography Distribution
Sydney Santos created and sold videos depicting minors in explicit physical acts. The materials were not required to meet the Miller obscenity test. The state's compelling interest in preventing actual exploitation of children supported criminal penalties for the sale.

Seth Shapiro displayed signs depicting certain forms of adult physical intimacy while the city ordinance banned only those carrying a disfavored political message. The selective prohibition triggered strict scrutiny. The ordinance fell because it regulated speech on the basis of viewpoint.

Frequently Asked

When does private consensual sexual activity between adults receive constitutional protection?+
The Due Process Clause protects private, noncommercial sexual conduct between fully consenting adults. Moral disapproval alone supplies no legitimate governmental objective. A statute criminalizing such conduct fails rational-basis review.
Why may the government criminalize visual depictions of minors engaged in sexual activity even when the material is not obscene?+
Child pornography constitutes a distinct unprotected category of speech. The government possesses a compelling interest in protecting children from sexual exploitation. This interest justifies bans on sale and distribution regardless of Miller standards.
Under what circumstances may a defendant introduce evidence of a sexual-assault victim's prior sexual activity?+
Rule 412 generally excludes such evidence. Limited exceptions permit proof offered to show an alternative source of semen or injury or when exclusion would violate the defendant's constitutional rights. The court must weigh probative value against prejudice in each instance.
