Under the Bharatiya Nyaya Sanhita, the definition of consent is stringent: it must be a voluntary agreement of the woman to engage in sexual activity, expressed through words, gestures, or any form of verbal or nonverbal communication. Consent given under fear, misconception of fact, or under the influence of intoxicants is not consent at all. The law also removes the presumption of consent where the act involves a spouse in specified circumstances.
The prosecution generally does not need to prove physical resistance, and the absence of injury is not treated as consent. Courts proceed on the totality of the circumstances, including the relationship between the parties, the age of the woman, the sequence of events, and any conduct immediately surrounding the incident. The burden rests on the defence to establish that consent was free and voluntary, and a mere claim unsupported by credible evidence rarely succeeds.
In practice, the credibility of the complainant and the consistency of her account across the FIR, the recorded statement, and the examination-in-chief matter greatly. The defence will test every inconsistency, so the prosecution must be prepared with corroborating material such as messages, call records, and eyewitness or forensic evidence. An advocate who understands how consent is analysed can advise on whether a matter should proceed to trial or be negotiated at a stage where the law permits.
