In law, a conviction is the determination by a court of law that a defendant is guilty of a crime. A conviction may follow a guilty plea that is accepted by the court, a jury trial in which a verdict of guilty is delivered, or a trial by judge in which the defendant is found guilty.
The opposite of a conviction is an acquittal (that is, "not guilty"). In Scotland, there can also be a verdict of "not proven", which is considered an acquittal. Sometimes, despite a defendant being found guilty, the court may order that the defendant not be convicted. This is known as a discharge and is used in countries including England, Wales, Canada, Australia, and New Zealand.
