“We’re standing at the crossroads of some pretty significant internet law right now,” says Christopher Terry, associate professor of media law at the University of Minnesota.

The case brought by the porn industry over a Texas age-verification law could determine the fate of more than a dozen similar laws in other states.

A majority of the Supreme Court signaled Wednesday that Texas may be permitted to require some form of age verification for pornographic sites, but left open the possibility that deeper First Amendment questions may not be resolved immediately.
