In Rosen v. United States, the U.S. Supreme Court rules that a defendant’s Sixth Amendment right to “be informed of the nature and cause of the accusation” was not violated when the charge against him – sending obscene material through the mail – did not include a description of each image that was alleged to be obscene. The Court rules that it was not critical to helping with his defense at the lower court and also notes that he never raised the issue in his original trial. As long as he and the lower court were clear on the charges, then his rights were not violated.
