A Utah law requiring adult websites to verify the age of their users will remain in effect after a federal judge dismissed a lawsuit challenging its constitutionality. The judge said Tuesday that an industry group representing adult entertainers couldn’t sue Utah officials over the law because of how it's designed. The dismissal poses a setback for First Amendment and digital privacy advocates, who argue the law unfairly discriminates against certain kinds of speech, violates the First Amendment rights of porn providers and intrudes on the privacy of individuals who want to view sexually explicit materials.
