In Bruton v. United States, the U.S. Supreme Court rules that the Sixth Amendment’s confrontation clause was violated when the prosecution, at a trial of two co-defendants, introduces testimony about the oral confession of one (Mr. Evans) that implicated the other (Mr. Bruton). Mr. Evans decided not to take the stand as a witness – exercising his Fifth Amendment right against self-incrimination – and so Mr. Bruton was not able to cross-examine Mr. Evans about his confession.
