A federal judge has refused to temporarily block the state of Louisiana from enforcing a new law that limits sex offenders’ access to social networking websites and other online forums.

The American Civil Liberties Union of Louisiana had asked U.S. District Judge Brian Jackson for a temporary restraining order that would prevent Gov. Bobby Jindal and Attorney General James “Buddy” Caldwell from enforcing the law that took effect on Monday.

But the judge ruled Friday that Jindal and Caldwell don’t have the authority to take the action that the ACLU is seeking.

The ACLU claims the law is overly broad and unconstitutional. The group says the law may have targeted sites like Facebook and MySpace but also blocks access to newspaper sites, job databases and other websites.
