Illinois’ highest court ruled Thursday that it is unconstitutional to ban convicted sex offenders from social media sites.

Conrad Allen Morger was convicted of sexually abusing a minor and sentenced to four years of probation by a court in McLean County. That came with a binding condition he not use specific internet sites, such as Facebook, Twitter, Instagram and LinkedIn.

During oral arguments, held in September in Godfrey, Morger’s representative said the ban is a violation of the U.S. Constitution’s First Amendment fundamental right to freedom of speech.
