Guidance on the approach when reviewing documents disclosed by your opponent in civil proceedings subject to the disclosure regime under Civil Procedure Rule (CPR) 31, Practice Direction (PD) 31A and PD 31B, including steps to analyse and, if appropriate, challenge aspects of the opponent's disclosure.

Disclosure in the B&PCs: a mandatory (save for limited exceptions) Disclosure Pilot Scheme (DPS) (under what was PD 51U) operated in the Business and Property Courts from 1 January 2019 until 1 October 2022. PD 57AD ("Disclosure in the Business and Property Courts") took effect on 1 October 2022, replacing PD 51U, and implementing, on a permanent basis, the procedures that operated under the DPS. For details of our materials considering the approach to disclosure under PD 57AD (and its predecessor, PD 51U), see Disclosure in the B&PCs toolkit.
