The presumption of innocence is a foundational legal principle that holds individuals accused of crimes to be regarded as not guilty until proven otherwise, placing the onus of proof firmly on the prosecution. Originating in Roman law, Talmudic teachings, and Islamic legal traditions, this idea highlights the need for strong evidence to achieve a conviction. Authors like R. Austin Freeman questioned its practical implementation, pointing out the gap between legal theory and the actual treatment of the accused, while Edward Douglass White upheld its significance as a fundamental pillar of criminal law, stressing that guilt must be determined beyond a reasonable doubt.
Henry M. Hunt demonstrated its procedural role as a safeguard that guides jurors until the evidence clearly contradicts the initial belief in innocence. Internationally acknowledged as a human right in the Universal Declaration of Human Rights, the presumption of innocence continues to serve as a crucial element of justice systems, ensuring procedural fairness while protecting individual freedoms.
