Disclosure has different meanings in England and Wales criminal proceedings and in civil claims governed by Civil Procedure Rule 31. The criminal process concerns relevant unused material and a continuing test applied by the prosecutor. The civil process concerns the existence of documents under the applicable rule and court order.
Before applying the word, identify the procedural framework, the material or documents involved and the person responsible for the next decision. Those details determine whether the issue is movement of unused material through a criminal investigation or a civil duty whose content and search scope come from CPR 31 and the court’s order.
Unused material in criminal proceedings
Investigators record and retain relevant material, a disclosure officer reveals it to the prosecutor, and the prosecutor applies the disclosure test. The sequence assigns a separate responsibility at each stage: preservation within the investigation, revelation to the prosecutor and assessment against the legal test. The disclosure officer occupies the investigation sequence and is not routinely selected by the court. The process does not mean that every item gathered is automatically given to the defence.
The prosecutor’s review of whether unused material is capable of undermining the prosecution case or assisting the defence is continuing. “Capable of” directs attention to the material’s possible effect on the two cases, while continuing review means the assessment is not exhausted when material first reaches the prosecutor. The same legal question can therefore be revisited as the case develops without becoming a different test at each stage.
Documents in civil claims under CPR 31
For a civil claim governed by Civil Procedure Rule 31, disclosure means stating that a document exists or has existed. The applicable rule and the court order determine the duty and the scope of any search. The definition and the obligation therefore perform different work: one identifies disclosure, while the other tells the party what must be done in the particular civil claim. This keeps the criminal undermine-or-assist test out of the CPR 31 inquiry.
