The prosecution can be directed to disclose its full list of witnesses before trial, since this information typically forms part of the police report and accompanying documents supplied to the accused under Section 207 CrPC (Section 230 BNSS) before charges are framed. Whether the prosecution can be directed to disclose its full list of witnesses before trial in a specific case depends on whether this disclosure was complete at the initial stage, and if any witnesses were omitted, a specific application can compel their disclosure before trial proceeds further. This obligation exists precisely to prevent trial by ambush, ensuring the defence has a genuine and fair opportunity to prepare rather than being surprised by unlisted witnesses partway through proceedings.

In practice, disclosure gaps can happen for a range of reasons — administrative oversight, late identification of additional witnesses during ongoing investigation, or in some cases, a deliberate attempt to hold back a witness whose testimony the prosecution wishes to introduce strategically later in trial. Regardless of the reason, the defence is entitled to know the complete list well in advance, since effective cross-examination depends heavily on having adequate time to review each witness's likely testimony and prepare accordingly.

Having complete visibility into prosecution witnesses is essential for effective cross-examination preparation, and this extends beyond simply knowing names — it includes access to their prior statements, any documents connected to their testimony, and sufficient time to investigate their background where relevant to credibility. If new witnesses are sought to be introduced mid-trial without proper prior disclosure, this can form valid grounds for objection or even exclusion of that testimony in appropriate circumstances.
