Privileged Evidence: Looking Beyond Yashwant Sinha v. CBI

The law of evidence has long recognised that certain communications — between lawyer and client, between spouses, or touching affairs of the State — are privileged from disclosure. The tension arises when documents claimed to be privileged, or obtained without authority, are pressed into service in judicial proceedings.

In Yashwant Sinha v. CBI (the Rafale review proceedings), the Supreme Court permitted reliance on documents sourced from unpublished records, observing that the manner of obtaining evidence does not necessarily bar its admissibility where the material bears on public interest and no statute prohibits its production. The decision sits in a line of cases stretching from Pooran Mal v. Director of Inspection, which favoured admissibility over the legality of collection.

Yet the position is not without limits. Sections 122 to 132 of the Indian Evidence Act, 1872 continue to protect specified relationships, and the right to privacy recognised in Puttaswamy introduces a constitutional dimension that earlier cases did not consider. This note, first published in the JLSR Journal, argues that admissibility of leaked material should turn on a structured balancing — public interest, proportionality, and the integrity of the privilege claimed — rather than a blanket rule either way.
