Presumption of Innocence

The presumption of innocence means that a person accused of a crime is treated as innocent unless guilt is proved through a lawful trial. The prosecution must ordinarily prove guilt beyond reasonable doubt; the accused does not have to establish innocence merely because an accusation has been made.

How the presumption operates

It determines the allocation and standard of proof in a criminal trial.

• The prosecution ordinarily bears the legal burden of proving every essential ingredient of the offence.
• If the evidence leaves a genuine reasonable doubt about guilt, the court must acquit the accused.
• The rule does not require proof beyond every imaginary doubt; it requires proof strong enough to exclude reasonable alternatives consistent with innocence.

Constitutional and evidentiary basis

Although not separately expressed in the Constitution, the presumption forms part of fair criminal procedure under Article 21. Article 20(3), which protects an accused from being compelled to testify against oneself, reinforces the accusatorial character of the process.

• The Bharatiya Sakshya Adhiniyam, 2023 governs the burden of proof and contains special rules for facts within particular knowledge and statutory exceptions.
• The Supreme Court has treated the presumption as a foundational principle of criminal jurisprudence and fair trial.

Limits and qualifications

The presumption is rebuttable and does not prevent lawful investigation, arrest, detention or prosecution where statutory conditions are satisfied.

• Legislatures may create reverse-burden clauses for specified offences, requiring the accused to explain or disprove particular facts.
• Courts generally require the prosecution first to establish the necessary foundational facts before a statutory presumption operates.
• Where an evidentiary burden rests on the accused, it is generally discharged on a preponderance of probabilities, a lower standard than the prosecution's burden.
