The Supreme Court has reserved its order on whether an accused has a statutory or constitutional right to inspect documents and evidence collected during investigation but not relied upon by the prosecution in its chargesheet. The question turns on the scope of Section 207 CrPC (Section 230 BNSS) and whether the right to a fair trial under Article 21 extends to materials the State chooses to withhold from its own case.

This case sits at the intersection of two foundational criminal procedure principles: the prosecution's disclosure obligation and the accused's fair-trial rights.

Under Section 207 CrPC (now Section 230 BNSS), a Magistrate must supply the accused — free of cost — copies of the police report, FIR, statements recorded under Section 161, confessions, and any other document on which the prosecution relies. The critical word is 'relies.' The statute, on its face, covers relied-upon documents only.

The accused's argument is that materials collected during investigation but kept out of the chargesheet may contain exculpatory evidence — evidence that could prove innocence or weaken the prosecution's case. Withholding such material, the argument goes, violates Article 21's guarantee of a fair trial and the principle against an unfair advantage by the State.

The prosecution's counter-argument is that disclosure is bounded by what it places before the court; the police case diary (Section 172 CrPC / Section 208 BNSS) is separately protected, and courts have only a limited power to direct inspection.

The broader doctrine at stake is the 'duty to disclose' versus 'adversarial system' tension. In UK and US law, unused material disclosure is a formal obligation. Indian law has been more restrictive. If the Supreme Court rules in favour of the accused, it would effectively constitutionalise a Brady-type disclosure rule — a significant shift in the balance between State secrecy in investigation and the accused's right to mount a full defence.
