Introduction

Chapter VIII of the BSA is now fully covered, and this run turns to Chapter VII ("Of the Burden of Proof"), working backward from its highest section just as the previous chapters were. Section 120 is that starting point, and it is one of the most consequential — and most misunderstood — provisions in the entire Act: the rule that tells a trial court what to presume the moment a rape complainant takes the stand and says, under oath, that she did not consent.

This article explains what Section 120 actually requires, the narrow category of prosecutions it applies to, the 1996 Supreme Court judgment that remains the definitive word on how the presumption operates in practice, and how it is deliberately structured as a rebuttable presumption rather than the stronger "conclusive proof" standard used elsewhere in the Act.

Section 120 BSA vs. Section 114A IEA: A Renumbering, Not a Rewrite

Section 120 carries forward Section 114A of the Indian Evidence Act, 1872 — itself inserted only in 1983, by the Criminal Law (Amendment) Act, in direct response to the Supreme Court's widely criticised acquittal in Tuka Ram v. State of Maharashtra (the "Mathura case"), which had held that the absence of visible injury on the complainant was fatal to a rape conviction. The operative wording is unchanged word for word; what changes is only the cross-references, since the underlying penal code itself has been replaced.

The aggravated categories under Section 64(2) BNS that trigger this presumption include rape by a police officer on a woman in custody, rape by a public servant on a woman in their custody, rape by armed forces personnel deployed in an area, rape by jail or hospital staff on an inmate or patient, rape by a person in a position of trust or authority (a relative, guardian, or teacher), rape during communal or sectarian violence, rape of a pregnant woman, rape of a woman incapable of giving consent, rape of a woman with a mental or physical disability, and repeated rape of the same woman. These are precisely the relationships of institutional or physical power imbalance where Parliament judged that requiring the complainant to affirmatively disprove consent, on top of everything else, was both unrealistic and unjust.

State of Punjab v. Gurmit Singh: Reading the Presumption As Parliament Intended

The leading authority on how this presumption is meant to function is State of Punjab v. Gurmit Singh, (1996) 2 SCC 384, decided by a bench of Dr. A.S. Anand and Saiyad Saghir Ahmad, JJ. A schoolgirl was abducted after an examination and raped by three men, one after another. The trial court acquitted all three, treating minor inconsistencies — her not knowing the make of the car, her not raising an alarm while threatened — as fatal to her credibility.

The Supreme Court reversed, in terms that have since become the standard courts are expected to apply whenever Section 114A IEA (now Section 120 BSA) is in play. The Court held the trial court's appreciation of the evidence was "unreasonable" and "perverse": a rural teenager's unfamiliarity with car models proves nothing, silence under a death threat is natural rather than suspicious, and her conduct afterward — telling her parents first, reluctance to publicise the assault, and leading the police to the scene — was exactly what a genuine victim's conduct looks like. The judgment is as much about how courts should assess a complainant's testimony generally as it is about the presumption itself, and it is routinely cited for both propositions together.

Bhupinder Sharma v. State of Himachal Pradesh: Applying the Presumption to Gang Rape

In Bhupinder Sharma v. State of Himachal Pradesh, (2003) 8 SCC 551, the accused argued he could not be convicted because the victim managed to escape before he personally completed the act of rape, even though his co-accused had already raped her. The Supreme Court held that Explanation 1 to Section 376(2) IPC (which deems every member of a group acting in furtherance of a common intention to have committed gang rape) operates together with Section 114A — once the group's rape of the victim was proved and she testified to non-consent, the presumption of non-consent applied to the prosecution as a whole, and the appellant's individual escape from completing the act did not extract him from that gang-rape liability. The case illustrates that Section 120's presumption is not read in isolation; it interacts with the substantive definitions of the aggravated categories it attaches to.

Worked Example: What the Presumption Does and Does Not Decide

A woman in judicial custody is raped by a member of the jail staff. At trial, the fact that intercourse occurred is not disputed — it is confirmed by medical evidence. The accused's defence is that the encounter was consensual. The woman testifies before the court that she did not consent. Because this is a Section 64(2)(d) BNS prosecution (rape by jail staff on an inmate), Section 120 is triggered: the court must presume she did not consent. The accused now carries the burden of rebutting that presumption with evidence — not mere assertion — that consent was in fact given, bearing in mind that "consent" obtained through the coercive backdrop of custodial power is itself scrutinised heavily under the substantive law of consent in Section 63 BNS.

Contrast this with an ordinary rape prosecution under Section 64(1) BNS, with no custodial or comparable aggravating relationship. There, Section 120 does not apply at all, and the prosecution carries the ordinary burden of proving absence of consent as part of proving the offence — the woman's testimony remains powerful evidence under general principles (a conviction can rest on the sole testimony of the prosecutrix if it is found credible, a separate line of authority from Section 120 itself), but there is no statutory presumption shifting the onus to the defence.

A Rebuttable Presumption, Not "Conclusive Proof"

Section 120 uses the phrase "the Court shall presume" — a category the Act treats as legally distinct from "the Court may presume" (discretionary) and from "conclusive proof" (irrebuttable, and not open to challenge by any evidence to the contrary). A "shall presume" finding under Section 120 is mandatory once its conditions are met, but it remains open to the accused to rebut it with evidence. This places it in the middle of the Act's three-tier presumption framework — stronger than a discretionary presumption the court is free to decline, but weaker than the "conclusive proof" standard the Act reserves for situations like the legitimacy presumption in Section 116, where no contrary evidence is permitted to be led at all once the conditions are satisfied.

Why This Matters in Practice

For prosecutors, Section 120 is a significant tool in exactly the cases where the power imbalance between accused and complainant is greatest — custodial settings, institutional care, positions of trust — precisely because those are the settings where a complainant is least likely to be able to marshal independent corroborating evidence of non-consent beyond her own testimony. For the defence, the section makes clear that once its conditions are met, a bare denial is not enough; rebuttal requires actual evidence. For judges, Gurmit Singh remains the standing instruction that testimonial inconsistencies of the kind natural to trauma and social circumstance are not, by themselves, grounds to disregard a complainant's evidence or to refuse the presumption Parliament has directed the court to draw.

Key Takeaways

1. Section 120 BSA reproduces Section 114A IEA (inserted 1983, post-Mathura) without substantive change, only updating cross-references from the IPC/Section 375-376 to the BNS/Sections 63-64.
2. The presumption applies only to the aggravated rape categories in Section 64(2) BNS (custodial, institutional, gang rape, and similar relationships of power) — not to every rape prosecution.
3. Once sexual intercourse is proved and the woman testifies she did not consent, the court's presumption of non-consent is mandatory ("shall presume"), though rebuttable by evidence from the defence.
4. State of Punjab v. Gurmit Singh, (1996) 2 SCC 384, remains the definitive authority on both the presumption itself and on how courts must evaluate a complainant's credibility without penalising natural inconsistencies born of trauma or circumstance.
5. Bhupinder Sharma v. State of Himachal Pradesh, (2003) 8 SCC 551, confirms the presumption operates alongside the substantive gang-rape provisions, not in isolation from them.

Conclusion

Section 120 opens this project's coverage of Chapter VII, "Of the Burden of Proof," at its highest section number. Unlike Chapter VIII's tightly self-contained three-section structure, Chapter VII runs from Section 120 down to Section 104 and gathers together some of the Act's most frequently litigated presumptions — dowry death, abetment of suicide by a married woman, and legitimacy among them — each addressed as this run continues backward through the chapter one section at a time.
