Presumption of Innocence

Criminal Law and Procedure Doctrine
Origin Traceable in principle to Roman law; articulated as a modern civil right in Article 9 of the French Declaration of the Rights of Man and of the Citizen (1789).

The presumption of innocence is the principle that a person accused of a crime is considered innocent until proven guilty, placing the burden of proof on the prosecution rather than requiring the accused to prove their own innocence. It is traceable in principle to a Roman law maxim that the burden of proof rests on the one who asserts, not the one who denies, and it was articulated as a modern civil right in Article 9 of the French Declaration of the Rights of Man and of the Citizen (1789). It is now recognized across common law, civil law and most mixed legal systems, and is enshrined in international instruments including Article 11 of the Universal Declaration of Human Rights (1948) and Article 14 of the International Covenant on Civil and Political Rights (1966).

  • Lead section, definition
    The presumption of innocence is a legal principle that every person accused of any crime is considered innocent until proven guilty. Under the presumption of innocence, the legal burden of proof is thus on the prosecution, which must present compelling evidence to the trier of fact (a judge or a jury).
