The Supreme Court agreed on Tuesday to hear a challenge to a Texas law that seeks to limit minors’ access to pornography on the internet by requiring age verification measures like the submission of government-issued IDs.

A trade group, companies that produce sexual materials and a performer challenged the law, saying that it violates the First Amendment right of adults.

The law does not allow companies to retain information their users submit. But the challengers said adults would be wary of supplying personal information for fear of identity theft, tracking and extortion.

Judge David Alan Ezra, of the Federal District Court in Austin, blocked the law, saying it would have a chilling effect on speech protected by the First Amendment.

“By verifying information through government identification, the law will allow the government to peer into the most intimate and personal aspects of people’s lives,” wrote Judge Ezra, who was appointed by President Ronald Reagan.

“It runs the risk that the state can monitor when an adult views sexually explicit materials and what kind of websites they visit,” he continued. “In effect, the law risks forcing individuals to divulge specific details of their sexuality to the state government to gain access to certain speech.”
