The US Supreme Court on Friday upheld a Texas law requiring pornographic websites to verify visitors’ ages, rejecting arguments that this violates free speech and boosting efforts to protect children from online sexual content, reported AFP.

The court’s decision will impact a raft of similar laws nationwide and could set the direction for internet speech regulation as concerns about the impact of digital life on society grow.

Texas is one of about 20 US states to institute checks that porn viewers are over 18, which critics argue violates First Amendment free speech rights.

Britain and Germany also enforce age-related access restrictions to adult websites, while a similar policy in France was blocked by the courts a week ago.

US companies like Meta, meanwhile, are lobbying Washington lawmakers for age-based verification to be carried out by smartphone giants Apple and Google on their app stores.

The Texas law was passed in 2023 by the state’s Republican-majority legislature but was initially blocked after a challenge by an adult entertainment industry trade association.

A federal district court sided with the trade group, the Free Speech Coalition, saying the law restricted adults’ access to constitutionally protected content.

But a conservative-dominated appeals court upheld the age verification requirement, prompting the pornography trade group to take its case to the Supreme Court, where conservatives have a 6-3 supermajority.

Under the law, companies that fail to properly verify users’ ages face fines up to $10,000 per day and up to $250,000 if a child is exposed to pornographic content as a result.

To protect privacy, the websites aren’t allowed to retain any identifying information obtained from users when verifying ages, and doing so could cost companies $10,000 daily in fines.

During arguments in January before the Supreme Court, a lawyer representing the Free Speech Coalition said the law was “overly burdensome” and that its goal could be accomplished using content filtering programs.

But Justice Amy Coney Barrett, the mother of seven children, took issue with the efficacy of content filtering, saying that from personal experience as a parent, such programs were difficult to maintain across the many types of devices used by kids.

Barrett also asked the lawyer to explain why requesting age verification online is any different than doing so at a movie theater that displays pornographic movies.
