Definition
A statutory provision that places the burden of proof (or some element of it) on the accused rather than the prosecution — the accused must prove their innocence or the absence of guilt on a specific element, once the prosecution establishes a prima facie case.
Reverse onus clauses in Indian law are found in special statutes dealing with serious economic crime, narcotics, and terrorism: (a) Prevention of Money Laundering Act (PMLA), 2002 (Section 24) — once the prosecution proves money laundering, the accused bears the burden of proving the proceeds are not derived from crime; (b) Narcotic Drugs and Psychotropic Substances (NDPS) Act, 1985 (Section 35) — once the prosecution proves possession, the accused bears the burden of proving they lacked the requisite knowledge and intent; (c) UAPA, 2019 — burden on accused to prove they are not members of a terrorist organisation. The constitutionality of reverse onus clauses has been upheld by the Supreme Court as a reasonable restriction, subject to the condition that the accused only needs to raise a reasonable doubt (not prove innocence beyond reasonable doubt).
Statutory Definition
Section 24, Prevention of Money Laundering Act (PMLA), 2002: 'When a person is accused of having committed the offence of money-laundering, the burden of proving that the proceeds of crime are untainted property shall be on the accused.' Section 35, NDPS Act, 1985: 'In any prosecution for an offence under this Act which requires a culpable mental state of the accused, the court shall presume the existence of such mental state but it shall be a defence for the accused to prove the fact that he had no such mental state with respect to the act charged as an offence in that prosecution.'
Etymology & Origin
From Latin 'reversio' (a turning back) + 'onus' (burden). A 'reverse' onus 'turns back' the normal allocation — instead of the prosecution proving every element, the accused must prove (or disprove) a specific element.

Reverse Onus: When the Accused Must Prove
The presumption of innocence — that the accused need not prove anything — is a foundational principle of criminal law. But some special statutes reverse this for specific elements: once the prosecution proves the accused possessed drugs, or that money passed through their accounts, the accused must prove they lacked criminal knowledge or intent. These reverse onus clauses represent legislative judgments that the normal allocation of proof is inappropriate for certain categories of serious crime.
Constitutional Validity: Article 20(3) and Article 21
Reverse onus clauses have been challenged as violating Article 20(3) (right against self-incrimination) and Article 21 (fair trial). The Supreme Court in Noor Aga v. State of Punjab (2008) 16 SCC 417 upheld the NDPS reverse onus but held: (a) the accused only needs to prove the exculpatory fact on the balance of probabilities — not beyond reasonable doubt; (b) the prosecution must first establish the primary fact (possession) before the reverse onus is triggered; (c) the reverse onus cannot extend to every element of the offence — it can only cover specific elements where the accused has special knowledge. Blanket reversal of the entire burden would be unconstitutional.
PMLA Reverse Onus: The Serious Challenge
The PMLA (Section 24) has been widely criticised for its extremely broad reverse onus — it effectively requires accused persons to prove that any money in their possession is clean money (not proceeds of crime), once the prosecution alleges money laundering. This creates serious due process concerns: the accused must disprove a negative. The Supreme Court in Vijay Madanlal Choudhary v. Union of India (2022) 7 SCC 1 upheld the PMLA framework including Section 24, holding that the reverse onus was reasonable given the nature of money laundering as a transnational, sophisticated crime.
“Reverse onus clauses are not unconstitutional per se — but they must respect limits. The accused bears the lesser burden (balance of probabilities); the prosecution must first establish a prima facie case; and the reversal must be limited to elements within the accused's special knowledge. Beyond these limits, reverse onus becomes presumption of guilt.”
