The Sixth Amendment guarantees the right to a speedy trial. This right is considered one of the most important in the Constitution. Without it, criminal defendants could be held indefinitely under a cloud of unproven criminal accusations. The right to a speedy trial also is crucial to ensuring that a criminal defendant receives a fair trial. If too much time elapses between the alleged crime and the trial, witnesses may die or leave the area, their memories may fade, and physical evidence may be lost.
