In Hoyt et al. v. Minnesota, the U.S Supreme Court was asked to consider whether a state law that prohibited the sale of "obscene" materials violated the First Amendment's guarantee of freedom of speech. The case arose when a bookstore owner in Minneapolis was convicted under this law for selling an adult magazine deemed obscene by local authorities. The defendant argued that the law was unconstitutional because it gave too much discretion to individual judges and juries to determine what constituted obscenity, thus creating an undue chilling effect on free expression. The Supreme Court upheld his conviction and ruled that states have broad power to regulate obscene material without violating constitutional rights as long as their laws do not go beyond certain limits defined by previous court decisions on obscenity cases (such as Roth v United States). In particular, they noted that while some may find such material offensive or immoral, others might see them differently; hence it is up to each community (through its elected representatives) rather than courts or bureaucrats at national level -to decide where these boundaries should lie.

In the dissenting opinion for Hoyt et al. v. Minnesota, the justice argued that the state's law prohibiting picketing near a courthouse was unconstitutional as it violated First Amendment rights to free speech and assembly. The justice contended that peaceful picketing is an essential form of political expression in American society and should not be restricted without compelling reasons. They also disagreed with the majority's view that such restrictions were necessary to ensure fair trials, arguing instead that there are other less restrictive means available to protect this interest, such as sequestering juries or moving trials when needed. Furthermore, they expressed concern about potential misuse of this law by authorities seeking to suppress unpopular views or protests against government actions under guise of protecting judicial process.
