Sixth Amendment to the United States Constitution
If the delay in bringing a defendant to trial exceeds one year following the arrest, this will trigger a presumption that the Sixth Amendment right to a speedy trial may have been violated. The government may counter if they have good or plausible reasons for the delay. Requests by the prosecution for additional time may be granted if plausible. But if none are offered or the court finds the reasons not plausible, they may dismiss the indictment, overturn a conviction or hear other remedies the defense might seek.
