How can I obtain disclosure and evidence from the prosecution in the UK?
Executive summary
To obtain prosecution disclosure in England and Wales the law requires the prosecution team (police and Crown Prosecution Service) to identify, schedule and provide unused material that is “relevant” — i.e. capable of undermining the prosecution case or assisting the defence — under the Criminal Procedure and Investigations Act 1996 and associated guidance and rules (CPS Disclosure Manual; Attorney‑General’s Guidelines) [1] [2]. Parliament and oversight bodies have repeatedly found systemic failings and pushed reform and protocols to strengthen timely, complete disclosure [3] [4].
1. What the law says: the duty to identify, schedule and disclose
The prosecution’s statutory and common‑law duty is to search for material gathered in the investigation, decide what is “relevant” and record that material on a Disclosure Schedule; that schedule (and disclosable material) must be provided to the defence so the defendant can challenge the case [5] [1]. The CPS Disclosure Manual sets out practical steps and warns that failure to comply can lead to stays for abuse of process, exclusion of evidence, or a successful appeal [1].
2. Practical tools and official guidance you should expect them to use
Senior guidance governs how disclosure is managed: the CPS Disclosure Manual, the Attorney‑General’s Guidelines (revised 2024), and Criminal Procedure Rules/Practice Directions set expectations for timing (for example initial disclosure around Plea and Trial Preparation Hearing) and for handling digital and third‑party material [6] [2] [7]. These documents require investigators and prosecutors to coordinate disclosure work and to deploy tools such as keyword searches and digital evidence recovery where necessary [6].
3. What you can do as a defendant or defence lawyer
Defence teams should expect to receive the Disclosure Schedule and relevant unused material; early specialist intervention is routinely recommended to identify disclosure failures and challenge incomplete schedules before procedural decisions become fixed [8] [1]. Where material is withheld, the prosecution must justify it and there are procedures (including defence applications to the court) that can result in exclusion of material or other remedies if duties under CPIA are not met [1].
4. When disclosure goes wrong — systemic concerns and parliamentary scrutiny
High‑profile collapses and inspections prompted parliamentary inquiries and joint improvement plans because police and CPS practices repeatedly failed to deliver full disclosure, particularly with the surge in digital material and multi‑agency investigations [3] [4]. Parliament’s inquiry and official reports drove recommendations and ongoing commitments to rebuild public confidence in disclosure [3] [4].
5. Third‑party and sensitive material: special rules and delays
Material held by third parties or that raises national security/public interest immunity requires careful handling under specific CPS guidance and potentially judicial procedures; the CPS guidance emphasises assembling linked documents together (e.g. collision reports, CCTV) and balancing competing public‑interest considerations before disclosing to third parties or defence [9] [6]. The Attorney‑General’s Guidelines and CPS protocol outline how to treat sensitive material and when a court may be asked to rule [2] [6].
6. Court process and timing: where disclosure is addressed in hearings
Criminal Procedure Rules and Practice Directions allocate disclosure issues into case management stages; the prosecution is expected to serve initial disclosure as soon as practicable (typically around PTPH) and to keep disclosure ongoing, with courts able to direct timing and scope [7] [2]. Failure to produce timely disclosure can be raised at procedural hearings and grounds for judicial remedies exist [2] [1].
7. Competing perspectives and limits of the official line
Official sources stress improved procedures, standardisation and tools to meet disclosure duties; outside observers and defence specialists warn that exponential growth in digital evidence, resource pressures across police and CPS, and inconsistent local practices remain obstacles — hence repeated calls for early specialist defence involvement [8] [4]. Available sources do not mention specific step‑by‑step checklists a lay defendant should use; the guidance assumes legal representation and institutional procedures (not found in current reporting).
8. How to press the issue practically in your case
Seek legal advice immediately so disclosure obligations can be monitored; ask for the Disclosure Schedule and inspection of material, make written requests, and be prepared to apply to the court if schedules are incomplete or material is withheld without proper justification — courts can exclude evidence or stay proceedings for disclosure failures [1] [2]. The CPS materials and Attorney‑General’s Guidelines explain the formal channels by which the prosecution must manage and justify disclosure decisions [1] [2].
