Case Law On Evidence Act And Rules Of Admissibility In Criminal Proceedings
🔹 1. Introduction
The Indian Evidence Act, 1872 (IEA) governs the admissibility, relevancy, and weight of evidence in criminal and civil proceedings in India.
In criminal proceedings, the main objective is to establish guilt beyond reasonable doubt, while ensuring fair trial rights.
Key Concepts
Relevancy (Sections 5–55): Evidence must relate directly to facts in issue.
Admissibility (Sections 56–100): Only legally recognized evidence can be admitted.
Burden of Proof (Sections 101–114): Prosecution bears burden in criminal cases; some exceptions exist.
Presumption of Law (Sections 4, 79–114A): Certain facts are presumed unless disproved.
Confessions and Statements (Sections 24–30, 32): Only admissible under strict conditions.
Documents (Sections 61–90): Must be genuine, properly proved to be admissible.
Exclusion of Evidence: Evidence obtained illegally (torture, unlawful search) may be excluded.
🔹 2. Landmark Case Laws

No link should be missing to ensure guilt beyond reasonable doubt.
Significance:
Shows courts’ approach to evaluating circumstantial evidence for admissibility and conviction.
Case 7: State of Rajasthan v. Kashi Ram (2006) 12 SCC 254
Topic: Corroboration of testimony

🔹 3. Key Principles from Case Law
| Principle | Statutory Provision | Case Law Example |
|---|---|---|
| Voluntariness of confessions | Sections 24–25 IEA | P.K. Basu v. State |
| Electronic evidence admissibility | Section 65B IEA | State of U.P. v. Rajesh Gautam |
| Expert opinion weight | Sections 45–51 IEA | Dr. Praful Desai case |
| Spontaneous statements (res gestae) | Section 6 IEA | Queen Empress v. Wasan Singh |
| Circumstantial evidence | No direct provision, judicial principle | N. S. Thapa v. Karnataka |
| Corroboration not mandatory | No direct provision | State of Rajasthan v. Kashi Ram |
🔹 4. Analysis
Admissibility depends on statutory compliance and judicial scrutiny: Courts rigorously check for voluntariness, authenticity, and relevancy.
Flexibility for modern evidence: Digital, electronic, and circumstantial evidence are increasingly recognized.
Balancing rights of accused and society: Confessions, hearsay, and expert evidence require careful validation.
Judicial precedents guide evaluation: Even if law is silent, courts rely on principles laid down in earlier cases.
🔹 5. Conclusion
The Indian Evidence Act is central to criminal proceedings. Landmark cases show:
Confessions must be voluntary (P.K. Basu)
Electronic evidence is admissible with proper certification (Rajesh Gautam)
Expert and circumstantial evidence need careful judicial evaluation (Praful Desai, Thapa)
Spontaneous statements (res gestae) can be admitted (Wasan Singh)
Credibility and chain of evidence matter more than sheer number of witnesses (Kashi Ram)
Courts maintain balance between evidentiary rules and justice, ensuring trials are fair, rigorous, and based on reliable proof.
