What is IPC Section 85?
IPC Section 85 sits in Chapter IV of the Indian Penal Code, "General Exceptions," directly following Section 84 (unsoundness of mind). The Code treats involuntary intoxication as functionally similar to genuine unsoundness of mind — in both cases, the person's capacity to understand and control their conduct has been compromised through no fault of their own, and the law recognises that criminal liability should not attach in the same way it would to a person acting with full mental capacity.
The critical, narrowing feature of this section is the requirement that the intoxication be genuinely involuntary — administered "without his knowledge or against his will." This distinguishes Section 85 sharply from the far more limited protection available under Section 86, which addresses voluntary intoxication and generally holds a person to the same standard of knowledge as if they had been sober, even where actual intent may have been affected.
Important Update: IPC to BNS Transition
With effect from 1 July 2024, the Indian Penal Code has been replaced by the Bharatiya Nyaya Sanhita (BNS), 2023 for offences committed on or after that date. Section 85 IPC now corresponds to Section 23 of the BNS, which retains the same substantive scope and requirements.
Legal Provision — Text of Section 85 IPC
This provision must be read together with Section 86, which addresses the separate and more limited scenario of voluntary intoxication — where an offence requires a particular intent or knowledge, a voluntarily intoxicated person is generally held to have had the same knowledge as they would have had if they had not been intoxicated, sharply limiting the defence available in that context compared to Section 85's fuller protection for involuntary intoxication.
Nature of Section 85 & the Burden of Proof
| Nature of Provision | General Exception — defines circumstances in which intoxication negates criminal liability; it does not create or punish any offence itself |
|---|---|
| Who Must Prove It | The accused, on a preponderance of probabilities, that the intoxication was genuinely involuntary and rendered them incapable as described |
| Legal Basis for the Burden | Section 105 of the Indian Evidence Act, 1872 (now Section 109 of the Bharatiya Sakshya Adhiniyam, 2023), which presumes the absence of circumstances bringing a case within a General Exception unless the accused proves otherwise |
| Evidence Typically Relied Upon | Medical reports, witness testimony, and circumstances surrounding how the intoxicating substance came to be consumed |
| Effect if Established | The act is treated as not amounting to an offence, in the same manner as if the accused suffered from genuine unsoundness of mind under Section 84 |
Because voluntary intoxication is so much more common than the genuinely involuntary scenario this section addresses, courts scrutinise claims under Section 85 carefully, generally requiring credible, specific evidence — rather than a bare assertion — that the intoxicating substance was administered without the accused's knowledge or against their will.
Key Ingredients / Essential Elements
Intoxication rendering incapacity
The accused must have been, by reason of intoxication, incapable of knowing the nature of the act, or that it was either wrong or contrary to law, at the time of doing it.
The intoxication must be genuinely involuntary
The intoxicating substance must have been administered to the accused without their knowledge, or against their will — deliberately choosing to consume it, even if the degree of intoxication was unexpected, does not satisfy this requirement.
How Section 85 Relates to Neighbouring Provisions
- Section 84 provides the parallel defence for a person of unsound mind, incapable of knowing the nature of their act or that it was wrong or contrary to law.
- Section 85 (this section) extends similar protection where incapacity arises from genuinely involuntary intoxication.
- Section 86 addresses voluntary intoxication specifically — where an offence requires particular knowledge or intent, a voluntarily intoxicated person is generally held to the same standard as if sober, offering a far more limited defence than Section 85.
Together, these three provisions form a structured framework addressing how the Code treats impaired mental capacity — whether from genuine mental illness, involuntary intoxication, or voluntary intoxication — with the degree of protection calibrated according to whether the impairment arose through the accused's own choice.
Important Cases on Section 85
Mirza Ghani Baig v. State of Andhra Pradesh, (1997) 2 Crimes 19 (AP)
The Court held that voluntary drunkenness is no excuse for the commission of a crime, reaffirming that the protection available under Section 85 is strictly confined to cases of genuinely involuntary intoxication. The Court further clarified that, so far as knowledge is concerned, the same standard applies as in the case of intention — courts must attribute to the intoxicated person the same knowledge as if they had been sober, unless they were entirely deprived of their mental faculties at the relevant time.
