Retrial

Extracted from the Wikipedia article New trial.
In the United States, if a defendant is acquitted of a crime, the Fifth Amendment generally prohibits a retrial; thus, with few exceptions, a retrial only can occur if the verdict in the first trial was "guilty", or if there was no verdict. In other legal systems, the rules may be different. For example, in Canada, the Crown (prosecution) may seek leave to appeal an acquittal; if such an appeal is successful, a retrial may be ordered.
