Admissibility and Probative Value of Evidence

Evidence law separates whether a statement may be considered from how much it should be believed. Admissibility concerns whether the law permits a statement to be received as evidence for a particular purpose; probative value concerns its strength in proving or disproving a disputed fact. An admissible statement is therefore not automatically true or sufficient to establish a claim.

Admissibility: the legal threshold

Under the Bharatiya Sakshya Adhiniyam, 2023, evidence may be given of facts in issue and legally relevant facts, subject to applicable restrictions. Logical relevance alone does not guarantee admissibility.

• The court considers the purpose for which the statement is offered, the applicable evidentiary rule and any legal prohibition.
• The requirement that oral evidence must be direct generally prevents a witness from proving an event merely by repeating another person's account, unless a recognised rule permits it.
• A statement offered to prove that certain words were spoken raises a different evidentiary question from the same statement offered to establish that those words were true.
• Rules concerning privileged communications or prohibited confessions can exclude material despite its apparent relevance.

Probative value: the weight of admitted material

Once a statement is admitted, the court assesses its evidentiary weight in light of the whole record. Admission into evidence does not settle credibility or establish that the applicable standard of proof has been met.

• Weight depends on factors such as the speaker's opportunity to know the facts, consistency, possible bias and compatibility with other reliable evidence.
• Cross-examination can test a witness's perception, memory and credibility, helping the court assess the statement's reliability.
• Corroboration may strengthen a statement, but it is not an automatic requirement for every kind of testimony.
• An admissible statement may receive little weight, while reliable testimony may carry substantial weight without a large number of supporting witnesses.

Why an affidavit does not automatically prove its contents

An affidavit is a written statement sworn or affirmed before an authorised person. Its formal character does not conclusively establish the truth of every assertion.

• The Bharatiya Sakshya Adhiniyam excludes affidavits presented to a court or officer from its application; their use depends on the applicable procedural framework.
• Order XIX of the Code of Civil Procedure, 1908 permits courts, subject to its conditions, to allow proof by affidavit and provides for attendance of the deponent for cross-examination.
• Procedural permission to receive an affidavit and the weight ultimately attached to its contents remain distinct questions.
