The Supreme Court, in a recent ruling, quietly altered the standard of proof for an alibi plea in criminal trials. Traditionally, courts required the accused to prove alibi conclusively. The Court clarified that an accused only needs to raise a reasonable doubt about presence at the crime scene — not establish alibi beyond reasonable doubt. This shifts the evidentiary burden and aligns alibi with the general principle that the prosecution must prove guilt.

An alibi (Latin: 'elsewhere') is a defence where the accused claims to have been at a different location when the offence occurred. Under Section 11 of the Indian Evidence Act, 1872 (now Section 9 of BSA, 2023), facts inconsistent with the facts in issue are relevant — and alibi operates on this logic.

The traditional judicial position, reflected in cases like Dudh Nath Pandey v. State of U.P. (1981), held that the burden of proving alibi lies on the accused and it must be proved like any other fact — meaning a preponderance of probability. Courts often confused this with requiring near-conclusive proof, effectively treating alibi as a special positive defence that had to succeed entirely or fail.

The Supreme Court's latest ruling corrects this by holding that an alibi need not be proved beyond reasonable doubt by the accused. Instead, a successful alibi merely needs to create a reasonable doubt in the prosecution's case. The burden never shifts from the prosecution to prove guilt beyond reasonable doubt — the accused's alibi evidence is simply one tool to create that doubt.

This distinction matters enormously in practice: a weak alibi that cannot be proven conclusively can still succeed if it raises enough doubt. For CLAT PG aspirants, this intersects with Section 103 of the Indian Evidence Act (burden on person asserting a fact), Section 105 (burden of proving exceptions), and the constitutional presumption of innocence under Article 21.
