Mitchell v. United States (1999)
Mitchell was told that by making a guilty plea she was waiving her Fifth Amendment right to remain silent during the trial.The District Court ruled that as a result of her guilty plea, Mitchell had forfeited the right to remain silent about the crime's details.The District Court accepted the testimony of her co-defendants' that put her over the five-kilogram threshold and that therefore the 10-year minimum sentence was mandated.It also held that the trial court may not draw adverse inference by the defendant's silence while facts bearing upon the severity of the sentence are considered.In addition, had the court allowed for an inference to be made from silence, suspicions would then inherently supersede and contradict the principle that defendants are innocent until proven guilty.
