C. Federal constitutional provision

In Letellier, supra, the Maine Supreme Court embraced the First Circuit's analysis in Bruno & Stillman, Inc. v. Globe Newspaper Co., 633 F.2d 583 (1st. Cir. 1980), and held that "The First Amendment thus requires that we balance the competing societal and constitutional interests on a case-by-case basis, weighing any possible injury to the free flow of information against the recognized obligation of all citizens to give relevant evidence regarding criminal conduct."
