New Britain Superior Court Judge Stephen Frazzini has enjoined the Connecticut Law Tribune from publishing an article based on a court document that had previously been posted on the state Judicial Branch website.

Daniel J. Klau, the newspaper’s lawyer, has filed an appeal to the judge’s Nov. 24 decision. He and other media law attorneys say this appears to be an extraordinarily rare case of prior restraint on free expression guaranteed by the First Amendment. They say that prepublication court orders normally have been deemed constitutional only in matters of extreme threats to public safety, on the level of national security.
