A mistrial in a criminal prosecution may prevent retrial under the Double Jeopardy provision of the Fifth Amendment, which prohibits an individual from being tried twice for the same offense, unless required by the interests of justice and depending on which party moved for the mistrial.
When a judge cancels a trial, she declares a mistrial. In other words, she decides that some mistake has been made and the trial must begin again from the start, with a new jury. There are several reasons that a judge might declare a mistrial, including a hung jury, which is when the jury can't come to a unanimous decision. There might also be misconduct by an attorney, or improperly introduced evidence. A mistrial usually means having to start all over again.
