Presumption of Innocence

Presumption of innocence is a legal right that the accused in criminal trials has in many modern nations. It states that no person shall be considered guilty until finally convicted by a court. The burden of proof is thus on the prosecution, which has to convince the court that the accused is guilty beyond a reasonable doubt. In principle, the defense does not have to 'prove' anything. However, the defense may present evidence tending to show that there is a doubt as to the guilt of the accused.

INNOCENCE, PRESUMPTION OF - The indictment or formal charge against any person is not evidence of guilt. Indeed, the person is presumed by the law to be innocent. The law does not require a person to prove his innocence or produce any evidence at all. The Government has the burden of proving a person guilty beyond a reasonable doubt, and if it fails to do so the person is (so far as the law is concerned) not guilty.
