CPR Part 35, Applies to All Forensic Disciplines
All forensic expert witnesses in UK civil proceedings are governed by CPR Part 35, regardless of whether they are forensic accountants, forensic engineers, digital forensics specialists, or forensic economists. The expert's primary duty is to the court, not to the instructing party. This duty requires the expert to provide independent, objective evidence that assists the court on matters within their expertise, even where that evidence does not support the instructing party's case.
CPR Part 35 and the accompanying Practice Direction set out detailed requirements for expert reports, including: the expert's qualifications and experience; the instructions received; the documents and information relied upon; the methodology applied; the expert's opinions; and a statement of truth signed by the expert. Experts must not assume the role of advocate and must distinguish between facts and opinions.
The duties established in The Ikarian Reefer [1993] 2 Lloyd's Rep 68 remain the foundation of expert witness practice in England and Wales. These duties, independence, objectivity, and the primacy of the duty to the court, apply with equal force across all forensic disciplines. Experts must also comply with obligations around joint expert meetings, joint statements, and the court's case management directions.
Failure to comply with CPR Part 35 can result in the expert's evidence being excluded, heavily discounted, or subject to adverse costs consequences. Solicitors instructing forensic experts should ensure that letters of instruction are clear, that experts are given access to all relevant documents, and that experts understand their overriding duty to the court from the outset of the instruction.
Single Joint Expert (SJE) vs Party-Appointed Expert (PAE)
Under CPR Part 35, the court may direct that evidence on a particular issue is to be given by a Single Joint Expert (SJE) instructed jointly by the parties, or by party-appointed experts (PAEs) instructed separately by each side. The choice has significant implications for cost, strategy, and the quality of expert evidence presented to the court.
A Single Joint Expert is instructed by both parties under a joint letter of instruction and produces one report addressing the agreed issues. The SJE model reduces the cost of duplicate expert analysis, limits the risk of polarised expert evidence, and is increasingly favoured by courts in cases where the technical issues are capable of objective analysis. Either party may ask questions of the SJE in writing, and the SJE may be cross-examined at trial. The court may also permit a party to instruct their own expert where the SJE's report is disputed, subject to cost consequences.
A Party-Appointed Expert is instructed by one party alone and provides independent evidence within their discipline. PAEs are appropriate where the issues are genuinely contested, where each party needs independent analysis to assess settlement prospects, or where the court has not directed a joint expert. In complex multi-discipline disputes, it is common for each party to appoint separate experts in each relevant discipline, for example, separate forensic accountants, digital forensics experts, and quantum experts on each side.
Regardless of whether the expert is an SJE or PAE, CPR Part 35 applies equally: the expert's primary duty is to the court, the report must be objective and independent, and the expert must cooperate in narrowing issues through joint meetings and joint statements where directed.
Hot-Tubbing (Concurrent Evidence)
Hot-tubbing, formally known as concurrent evidence, is a procedure increasingly used in UK courts and international arbitration where experts from both sides give evidence simultaneously before the judge or tribunal, rather than in the traditional sequential format of examination-in-chief followed by cross-examination.
In a hot-tubbing session, experts are sworn in together and the judge or arbitrator directs the discussion, asking questions, probing areas of agreement and disagreement, and inviting experts to respond to each other's opinions in real time. This format allows the tribunal to directly compare expert evidence, identify the true areas of dispute, and resolve technical questions more efficiently than traditional cross-examination.
Hot-tubbing is particularly common in the Technology and Construction Court (TCC) for quantum and delay disputes, in competition proceedings before the Competition Appeal Tribunal (CAT), and in international arbitration under ICC, LCIA, and ICSID rules. It is especially valuable in digital forensics cases where technical evidence is highly specialised, and in complex construction disputes where multiple disciplines, quantum, delay, and forensic engineering, are engaged.
Preparation for hot-tubbing requires experts to have participated in joint meetings, produced a joint statement identifying agreed and disputed issues, and be ready to explain their methodology and opinions clearly and concisely under direct questioning from the tribunal. Solicitors should ensure their forensic experts are experienced in concurrent evidence procedures before instructing them for cases where hot-tubbing is likely to be ordered.
