Introduction
Bestiality — broadly described as sexual intercourse or sexual acts between a human and a non‑human animal — sits at the intersection of criminal law, animal welfare law and evidentiary science. In the Indian legal landscape it is treated not merely as a sexual offence but as cruelty to animals and a public‑order concern. For practitioners, the offence raises distinctive evidentiary, procedural and strategic issues: proving the act (often in the absence of reliable eyewitnesses), preserving perishable biological and animal‑health evidence, and choosing the appropriate charging strategy (IPC, Prevention of Cruelty to Animals Act, ancillary provisions).
Core Legal Framework
- Indian Penal Code, 1860 — Section 377
- Text (key part): “Whoever voluntarily has carnal intercourse against the order of nature with any man, woman or animal shall be punished with imprisonment for life, or with imprisonment of either description for a term which may extend to ten years, and shall also be liable to fine.”
- Practical import: bestiality is captured under Section 377 as “carnal intercourse against the order of nature” with an animal. Section 377 therefore provides the primary criminal penal provision for penalizing sexual intercourse with animals.
- Prevention of Cruelty to Animals Act, 1960 (PCA Act)
- Section 3 (prohibitions) — proscribes causing unnecessary pain or suffering to animals and lists acts of cruelty; various subsections and rules under the PCA Act and subordinate legislation provide mechanisms for prosecution, seizure and penalties.
- Penalty provisions (PCA Act) — the Act imposes punishments and fines for cruelty, which can be pressed in addition to IPC charges.
- Code of Criminal Procedure, 1973
- Procedure for investigation (e.g., FIR under Section 154 CrPC), seizure, examination of witnesses, and forwarding of reports under Section 173 CrPC apply. Early steps under CrPC are critical to preserve perishable evidence.
- Rape law (IPC Section 375 et seq.)
- Rape provisions by definition apply to human victims and do not cover bestiality; this distinction is often relevant when advising clients and framing charges.
- Relevant jurisprudential context: Navtej Singh Johar v. Union of India, (2018) 10 SCC 1 — the Supreme Court read down Section 377 insofar as it criminalized consensual homosexual acts between adults in private; the judgment explicitly left intact the criminality of non‑consensual acts and acts involving animals. Therefore, decriminalization of consensual same‑sex activity did not legalize bestiality.
Practical Application and Nuances
How the offence is prosecuted and defended in practice hinges on three axes: proving the act, evidentiary chains for biological and animal evidence, and charge framing.
- Proof of the offence — what the prosecution must establish
- Essential elements to prove for Section 377 (animal):
- The accused had carnal intercourse (the penetrative element) or committed an act that falls within “unnatural” carnal intercourse;
- The act was with an animal (identity of the non‑human partner);
- The act was “against the order of nature” (the statutory language); and
- Mens rea (voluntariness) — that the accused voluntarily engaged in the act.
- Practical evidence commonly relied upon:
- Eyewitness testimony (very persuasive if credible, but frequently absent);
- Forensic biological evidence: semen, epithelial cells, DNA matching (from clothing, bedding, animal genitals or rectal/vaginal swabs);
- Veterinary/medical expert opinion: physical injury to the animal, signs of recent penetration, pathology reports, certificates from registered veterinarians;
- Photographs, CCTV or mobile phone recordings;
- Circumstantial evidence: bloodstains, torn clothing, blood/soil transfer, statements of the accused or accomplices.

- Proving penetration: courts often require reliable medical/forensic or eyewitness proof of penetration; where penetration cannot be established, the prosecution’s case is weakened.
- Perishability of animal evidence: decomposition, grooming, or slaughter can destroy crucial evidence quickly; time is therefore of the essence.
-
Investigation and evidence preservation — immediate steps
- FIR: If there is information of such an offence, an FIR should be recorded under Section 154 CrPC promptly. Delay can be fatal to the prosecution.
- Scene preservation: cordon off the scene; prevent cleaning/washing of clothing/bedding; obtain statements of first informant and bystanders while impressions are fresh.
- Forensic sampling:
- Human biological samples from accused and complainant/animal‑handler (buccal swabs) for DNA comparison;
- Swabs from animal genital/rectal area, clothing, bedding;
- Photographs of animal injuries from multiple angles with scales;
- Veterinary examination & certificate — get a registered veterinarian to examine the animal and give a written report describing injuries consistent with sexual assault.
- Chain of custody: document seizure, custody, transport and storage of all biological material; failures here are commonly exploited by defence.
-
Expert panels: coordinate with forensic laboratory, microbiology, serology and a veterinarian experienced in forensic animal pathology.
-
Charging strategy — multiple heads commonly used
- Primary charge: Section 377 IPC (carnal intercourse against order of nature with an animal).
- Concurrent charges: Offences under the PCA Act for cruelty to animals; offences relating to public obscenity (if acts occurred in public); offences relating to public order if public outrage ensued.
- Ancillary relief: For court orders for veterinary care, temporary custody of animal, or destruction/euthanasia orders only in appropriate circumstances and under statutory safeguards.
- Where applicable: If the accused is a repeat sexual offender or the incident involved a child, consider framing charges under child protection statutes or mental health evaluations.
Landmark Judgments
- Navtej Singh Johar v. Union of India, (2018) 10 SCC 1 (Supreme Court)
- While this judgment decriminalized consensual sexual acts between adults in private under Section 377, the Court expressly left intact the applicability of Section 377 to acts involving animals or non‑consensual acts. The decision therefore clarified that bestiality remains criminally punishable and not protected by the reasoning that struck down criminality of private consensual homosexual conduct.
- Animal Welfare Board of India v. A. Nagaraja, (2014) 7 SCC 547 (Supreme Court)
- Although concerned with performing animals, this decision is instructive on the Court’s approach to animal cruelty, statutory interpretation of the PCA Act and balancing cultural practices with statutory duties to prevent cruelty. The case underscores that acts causing unnecessary pain and suffering to animals attract penal consequences and public interest in animal welfare can inform prosecutorial and sentencing considerations in cases of bestiality.
Strategic Considerations for Practitioners
For prosecution
– Move immediately: early veterinary examination, forensic sampling and preservation of material evidence are indispensable.
– Build a multidisciplinary expert roster: a forensic serologist/DNA analyst, a veterinary pathologist, and where necessary, a psychologist/psychiatrist to provide context on the accused’s mental state.
– Frame charges carefully: plead Section 377 and relevant provisions of the PCA Act together to ensure multiple convictions are possible if evidence varies in strength.
– Witness management: secure and protect eyewitnesses and bystanders; anticipate hostile witnesses and prepare impeachment material where necessary.
For defence
– Attack the chain of custody and quality of forensic testing: failures in sampling, storage, or laboratory process can undermine DNA/semen evidence.
– Challenge proof of penetration: insist prosecution prove the penetrative element beyond reasonable doubt; in absence of direct proof, argue that contact alone does not meet statutory threshold.
– Identity and fabrication: investigate motives for false accusation (land disputes, personal vendetta, extortion) and gather alibi evidence, CCTV logs, phone records.
– Mental health mitigation: where accused shows paraphilic disorder or diminished capacity, consider psychiatric evaluation for sentencing mitigation (but note this does not negate criminal responsibility unless very severe).
Common pitfalls to avoid
– Delay in medical/veterinary examination: perishable biological evidence is easily lost; delayed examination is a frequent prosecutorial failing.
– Overreliance on confessions or community outrage: confessional statements must comply with CrPC and Constitution; public anger cannot substitute for forensic proof.
– Ignoring PCA Act avenues: prosecutors sometimes under‑charge, missing additional cruelty offences that provide alternative routes to conviction.
– Misreading Navtej Singh Johar: do not conflate decriminalization of consensual same‑sex acts with legality of bestiality; courts retain penal jurisdiction over acts involving animals.

Sentencing and aggravating factors
– Section 377 prescribes severe penalties (imprisonment up to life or up to ten years and fine). Sentences in practice will vary with gravity, injury to the animal, recurrence, and societal impact.
– Aggravating factors: repeated offences, public performance, commercial exploitation (e.g., live shows), or severity of injuries to the animal will attract harsher sentences and potential concurrent PCA Act penalties.
Ethical and professional notes
– Avoid gratuitous description of acts in filings and oral argument; plead facts plainly and clinically.
– Protect privacy of witnesses and sensitive evidence; where proceedings involve minors (either as perpetrators or observers), follow statutory safeguards and confidentiality rules.
– Coordinate with animal welfare NGOs where appropriate to secure veterinary expertise and rehabilitation for the animal.
Conclusion
Bestiality in India is criminal conduct primarily prosecutable under Section 377 IPC and, concurrently, under the Prevention of Cruelty to Animals Act. Successful prosecution depends on rapid, methodical preservation of fragile biological and veterinary evidence, credible eyewitness statements or recordings, and authoritative expert testimony. Defence strategies focus on undermining proof of penetration, chain of custody and identity issues. Practitioners must be methodical and interdisciplinary: coordinate police, forensic labs and registered veterinarians immediately, frame charges to cover alternate theories of liability, and handle the matter with the legal precision and ethical restraint the subject demands.
