Evidence Act And Admissibility In Criminal Trials
1. Introduction to Evidence Act in Criminal Trials
The Evidence Act, particularly the Indian Evidence Act, 1872, governs the admissibility, relevancy, and weight of evidence in criminal proceedings. It lays down rules for:
Types of Evidence:
Oral Evidence (Section 59)
Documentary Evidence (Sections 61–90)
Electronic Evidence (Sections 65A & 65B, added via IT Act amendments)
Relevance of Evidence:
Sections 5–16 define relevancy of facts, facts in issue, and connected facts.
Admissibility:
Evidence must be relevant, not barred by law, and obtained legally.
Illegally obtained evidence may be excluded.
Burden of Proof:
Sections 101–114 deal with who bears the burden of proof.
Presumptions (Sections 4–114A) shift the burden in certain cases.
Confessions and Statements:
Sections 24–30 regulate confessions and statements made to police.
Section 25 bars confessions made to police officers as evidence.
2. Admissibility Principles in Criminal Trials
Relevancy: Only facts relevant to the case are admissible (Sections 5–16).
Best Evidence Rule: Original documents must be produced when available (Section 64–65).
Hearsay Rule: Statements made outside the court are generally inadmissible, unless an exception applies (Section 32).
Confessions and Admissions:
Confession to a magistrate is admissible (Section 164 CrPC + Evidence Act).
Confession to police is inadmissible (Section 25).
Electronic Evidence: Digital records, emails, and logs are admissible under Sections 65A & 65B.
Exclusionary Principles: Evidence obtained illegally, by coercion, or violating rights is generally inadmissible.
