Detailed Study Notes for Unit III

Unit-III: Relevancy of Judgments, Expert Opinions, Oral/Documentary Evidence & Electronic Records

Previous Judgments Relevant to Bar a Second Suit (Section 34): The existence of any judgment, order, or decree which by law prevents any court from taking cognizance of a suit or holding a trial is a relevant fact when the question is whether such court ought to take cognizance or hold trial (principles of res judicata).
Relevance of Judgments in Probate, Matrimonial, Admiralty, or Insolvency Proceedings (Section 35): Final judgments delivered by a competent court exercising probate, matrimonial, admiralty, or insolvency jurisdiction are relevant when the existence of any legal character or title is in issue (judgments in rem).
Relevance of Other Judgments (Section 36): Judgments other than those mentioned in Sections 34 and 35 are generally irrelevant, unless the existence of such judgment, order, or decree is a fact in issue, or is relevant under some other provision of the Act.

As a general rule, the opinion of witnesses is inadmissible. Witnesses must state facts which they perceived with their own senses, leaving inferences to the court.

Expert Opinion (Section 39): When the court has to form an opinion upon a point of foreign law, science, art, identity of handwriting, or finger impressions, the opinions upon that point of persons specially skilled in such foreign law, science, or art (experts) are relevant facts.Illustration: The question is whether the death of A was caused by poison. The opinions of expert medical toxicologists as to the symptoms produced by the poison are relevant.
Opinion on Relationship / Handwriting / Custom (Sections 40 to 45): Opinions expressed by conduct as to the existence of any relationship between persons, opinions as to handwriting, or general customs and tenets are relevant.

Judicially Noticeable Facts (Section 56): Facts of which the court must take judicial notice need not be proved (e.g., laws in force in India, public acts of Parliament, accession of the President, course of time, geographical divisions, public festivals).
Facts Admitted (Section 58): No fact need to be proved in any proceeding which the parties thereto or their agents agree to admit at the hearing, or which, by any rule of pleading in force at the time, they are deemed to have admitted by their pleadings.

General Rule (Section 59): All facts, except the contents of documents or electronic records, may be proved by oral evidence.
Directness (Section 60): Oral evidence must in all cases be direct—if it refers to a fact which could be seen, it must be the evidence of a witness who says he saw it; if it refers to a hearing, it must be the evidence of a witness who heard it. Hearsay evidence is inadmissible.

Primary Evidence (Section 61): Means the document itself produced for the inspection of the court, including electronic or digital records stored in optical, magnetic, or semiconductor media.
Secondary Evidence (Section 62): Includes certified copies, copies made from the original by mechanical processes, counterparts of documents, and oral accounts of the contents given by a person who has inspected the original.
Special Provision as to Electronic Records (Section 63 / old IEA Sec. 65B): Electronic records produced from proper custody are deemed primary evidence if accompanied by a certificate complying with statutory requirements certifying the integrity, operation, and source of the computer output, validating digital evidence in criminal and civil trials.

Primary Rule (Section 94): When the terms of a contract, grant, or disposition of property have been reduced to the form of a document, no evidence of any oral agreement or statement shall be admitted as between the parties to any such instrument for the purpose of contradicting, varying, adding to, or subtracting from its terms.
Exception: Oral evidence is admissible to prove fraud, intimidation, illegality, want of consideration, or a subsequent oral rescission/modification.

Digital Footprints: Social media posts, chat transcripts (WhatsApp, Telegram), server logs, geotags, and metadata are admitted as electronic records under the BSA, subject to authentication via digital certificates and forensic verification.

Case Title: State of Maharashtra v. Sukhdev Singh
Citation & Court: AIR 1992 SC 2100 (Supreme Court of India)
Related Statutory Provisions: Section 39 of BSA (old IEA Sec. 45).
The Story & Real-Line Background: In a high-profile assassination and terror trial, prosecution relied heavily on forensic fingerprint experts and ballistic reports matching bullet casings to recovered firearms. The defense challenged the infallibility and conclusiveness of expert scientific testimony.
Legal Issues Involved: Whether expert opinion is conclusive proof or merely advisory, and how courts evaluate conflicting expert testimony.
Final Judgement & Ratio Decidendi:
- Ruling: The Supreme Court held that expert opinion under Section 39 is advisory and corroborative in nature, not substantive or conclusive. The court must independently evaluate the reasons and scientific methodology stated by the expert rather than blindly delegating judicial decision-making to the expert.
- Ratio: Expert evidence is opinion evidence; courts must critically evaluate underlying scientific data rather than treat expert opinions as infallible proof.

Case Title: Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal
Citation & Court: (2020) 7 SCC 1 (Supreme Court of India, 3-Judge Bench)
Related Statutory Provisions: Section 63 of BSA (old IEA Sec. 65B).
The Story & Real-Line Background: During an election petition, electronic records (video recordings and computer printouts) were produced in evidence without accompanying certificates under Section 65B of the old Evidence Act. The opposing party objected to their admissibility.
Legal Issues Involved: Whether a certificate under Section 65B (now Section 63 of BSA) is a mandatory condition precedent for the admissibility of electronic records.
Final Judgement & Ratio Decidendi:
- Ruling: The Supreme Court held that the certificate required under Section 65B(4) is a condition precedent to the admissibility of electronic records produced by a computer. Without this certification, electronic records cannot be admitted in evidence (except when original equipment is produced directly in court).
- Ratio: Statutory certification of electronic records is mandatory to ensure authenticity, integrity, and admissibility of digital evidence.
