when might a gag order be imposed in a trial
Gag order Gag orders are sometimes used in an attempt to assure a fair trial by preventing prejudicial pre-trial publicity, although their use for this purpose is controversial since they are a potentially unconstitutional prior restraint that can lead to the press's using less reliable sources such as off-the-record statements and second- or third-hand accounts.[3]
Grand juries in the United States Grand jury proceedings are secret. No judge is present; the proceedings are led by a prosecutor;[15] and the defendant has no right to present his case or (in many instances) to be informed of the proceedings at all. While court reporters usually transcribe the proceedings, the records are sealed. The case for such secrecy was unanimously upheld by the Burger Court in Douglas Oil Co. of Cal. v. Petrol Stops Northwest, 441 US 211 (1979).[16][17] The dissenting opinion was joined by Justices Burger and Stewart but concurred with the Court's opinion as to the importance and rationale of grand jury secrecy. Writing for the Court, Justice Powell found that "if preindictment proceedings were made public, many prospective witnesses would be hesitant to come forward voluntarily"; "witnesses who appeared before the grand jury would be less likely to testify fully and frankly"; and "there also would be the risk that those about to be indicted would flee, or would try to influence individual grand jurors". Further, "persons who are accused but exonerated by the grand jury [should] not be held up to public ridicule".[16]
