In Vance et al. v. Universal Amusement Co., Inc., et al, the Supreme Court of the United States ruled that a Texas statute allowing for state courts to issue injunctions against movie theaters showing films deemed "obscene" was unconstitutional. The court held that this law violated First Amendment rights as it constituted prior restraint on speech and did not provide adequate procedural safeguards to protect these rights. The decision emphasized that any system of prior restraints bears a heavy presumption against its constitutional validity due to potential abuse in suppressing disfavored speech or ideas, and thus requires stringent procedural safeguards which were lacking in this case.

The dissenting opinion in the case of Vance et al. v. Universal Amusement Co., Inc., et al. argued that the majority's decision was an overreach and a violation of First Amendment rights, as it allowed for prior restraint on speech without requiring proof that such material would incite violence or pose a clear and present danger to society. The dissenters believed this ruling could lead to censorship based purely on content rather than any potential harm caused by said content, which they saw as contrary to established constitutional principles protecting freedom of expression. They also expressed concern about the broad powers granted to judges under this ruling, arguing that it left too much room for subjective interpretation and potential abuse.
