Single Joint Expert vs Party-Appointed Expert: Speed and Strategy

When instructing an expert witness for UK legal proceedings, solicitors commonly weigh whether a single joint expert (SJE) or a party-appointed expert offers a faster and more efficient path. While the answer depends on the specific circumstances and co-operation between parties, often a single joint expert can, in theory at least, lead to a quicker resolution by streamlining the expert evidence process.

The Role of Expert Evidence in UK Litigation

Expert evidence is a critical component in many civil and criminal cases in the UK, assisting the court with technical or specialised matters beyond the knowledge of a lay person. This evidence must be independent and objective, adhering strictly to the requirements of the Civil Procedure Rules (CPR) Part 35 in civil cases, or the Criminal Procedure Rules (CrPR) Part 19 in criminal matters. The expert's primary duty is always to the court, not to the instructing party or parties.

Timely instruction and report delivery are paramount, especially given the often tight court deadlines and case management orders. Delays in obtaining expert evidence can lead to adjournments, increased costs, and potential sanctions from the court. Therefore, understanding the practical implications of instructing a single joint expert versus a party-appointed expert, particularly concerning speed, is vital for legal professionals.

Single Joint Expert: Potential for Speed and Efficiency

A single joint expert is instructed by two or more parties in a dispute to provide an impartial report to the court. The instruction of an SJE is governed by CPR Part 35.7 and its associated practice direction. The court can direct that evidence on a particular issue is to be given by a single joint expert, or the parties can agree to this arrangement.

Advantages for Speed

• Consolidated Instruction: Instead of each party instructing and briefing their own expert, leading to potentially duplicated effort, the SJE receives a single set of instructions agreed by all parties. This eliminates the time spent comparing instructions, collating documents for multiple experts, and managing parallel communications.
• Single Examination/Assessment: If the expert needs to examine a person, a property, or evidence, this is done once. For example, in a personal injury claim involving medical evidence, a single joint medical expert would examine the claimant once, rather than the claimant attending multiple appointments with different experts.
• Direct Access for All Parties: All instructing parties have direct access to the SJE to ask questions for clarification of their report, as per CPR Part 35.6. While this process has its own timeline, it avoids the protracted exchange of competing expert reports and subsequent discussions.
• Reduced Need for Meetings of Experts: In cases with party-appointed experts, a 'meeting of experts' is often directed by the court to identify areas of agreement and disagreement. While an SJE can be asked to clarify points, the need for a formal meeting to reconcile differing opinions is largely eliminated, saving considerable time.
• Cost-Sharing: While not directly related to speed, the shared cost burden can simplify budgeting and approval processes, indirectly contributing to smoother and faster instruction.

Potential for Delays

Despite the theoretical advantages, instructing a single joint expert can encounter delays, particularly during the instruction phase:

• Agreeing Instructions: A significant potential bottleneck is the requirement for all instructing parties to agree on a single set of instructions and a list of questions to be put to the expert. This can involve protracted negotiations, especially in contentious cases, delaying the SJE's formal engagement. Disagreements here can stall the process indefinitely.
• Finding an Agreed Expert: All parties must agree on the choice of the single joint expert. If parties cannot agree on a suitable candidate, the court may need to intervene, which adds considerable time and cost. Our service can help identify suitable experts quickly to mitigate this (see Our Experts).
• Lack of Independent Scrutiny: While not a delay, a perceived disadvantage is that parties cannot independently scrutinise the expert's methodology or conclusions as they might with their own expert. This can lead to parties being hesitant to agree to an SJE if the issues are complex or highly disputed.

Party-Appointed Expert: Control vs. Potential for Lengthier Process

A party-appointed expert is chosen and instructed by one party to a dispute to provide evidence in support of that party's case. Each party may instruct their own expert on the same issue. This is a common approach, particularly in high-value or complex litigation where parties seek to present their arguments optimally.

Advantages for Control (but not necessarily speed)

• Unilateral Instruction: Each party can choose their own expert without needing the opposing party's consent. This can speed up the initial instruction phase, as solicitors can move quickly to engage an expert who meets their specific requirements.
• Tailored Instructions: The instructing party can tailor the expert's brief and questions precisely to their case strategy, allowing for a more forensic examination of particular points beneficial to their position. This individualised approach can feel more efficient from the instructing party's perspective.

Disadvantages for Speed

• Multiple Reports: Having two (or more) experts often means two or more reports on the same issue. These reports may contain conflicting opinions, requiring further steps to reconcile.
• Meetings of Experts: A common consequence of party-appointed experts is the necessity for a 'meeting of experts' and subsequent joint statement, as required by CPR Part 35.12. This meeting is designed to narrow the issues and identify points of agreement and disagreement. Organising such meetings, preparing for them, and drafting the joint statement can be a time-consuming process. The parties need to agree on a date, attendance, and eventually, the wording of a joint statement, all of which can be delayed by scheduling conflicts or disagreements.
• Protracted Dialogue: Inevitably, conflicting expert evidence can lead to a more extensive 'Part 35 questions' process, and potentially requiring questions and answers to multiple experts. This means more communication, analysis, and possibly supplemental reports, all adding to the overall timeline.
• Trial Implications: If experts remain in disagreement, both may need to attend court to give oral evidence, potentially extending the trial length and increasing costs. This also means more time spent by legal teams preparing the experts for cross-examination.

Factors Affecting Timelines: Beyond the Instruction Model

While the choice between a single joint expert and a party-appointed expert influences speed, several other factors significantly impact the overall timeline for obtaining and using expert evidence:

• Expert Availability: The most qualified experts are often in high demand. Their current caseload, commitments, and response times for assessments and report writing are crucial. Finding an expert who can meet urgent deadlines is often challenging. Our network of experts is regularly updated to help with this.
• Complexity of the Case: More complex cases, requiring extensive analysis, research, or highly specialised expertise, will naturally take longer, regardless of the instruction model.
• Volume of Documents: The amount of documentation an expert needs to review directly correlates with the time required to formulate their opinion and draft their report. Efficient provision of clear, organised documents by the instructing solicitor is critical.
• Co-operation between Parties: In SJE cases, the willingness of all parties to co-operate in drafting instructions and agreeing on the expert speeds up the process. Conversely, in party-appointed cases, constructive engagement during meetings of experts and agreement on joint statements can mitigate delays.
• Clarity of Instructions: Ambiguous or incomplete instructions will inevitably lead to experts seeking clarification, causing delays. Clear, concise, and comprehensive instructions from the outset are paramount.
• Court Deadlines (Case Management Orders): The court imposes deadlines via Case Management Orders (CMOs). These deadlines often dictate the urgency, and failure to meet them can have serious consequences, emphasising the need for a swift process.

Strategic Considerations for Speed

For legal professionals aiming for the fastest possible resolution, strategic planning is essential:

• Early Identification: Identify the need for expert evidence and the specific type of expertise required as early as possible in the litigation cycle. This allows maximum time for selecting and instructing an expert. You can submit a request here.
• Proactive Expert Search: Begin the search for suitable experts promptly. For single joint experts, propose several credible candidates to the opposing side to increase the likelihood of rapid agreement.
• Draft Instructions Early: Prepare draft instructions and questions for the expert well in advance. For an SJE, circulate these to the opposing side for agreement without delay.
• Clear Communication: Maintain open and clear communication with the expert, providing all necessary documents efficiently and responding to queries promptly.
• CPR Compliance: Strict adherence to CPR Part 35 or CrPR Part 19 rules and practice directions helps avoid procedural missteps that can lead to delays or challenges to the expert evidence.

Best Practice for Instructing Experts

• Define the Scope: Clearly define the specific questions the expert is asked to answer and the scope of their remit.
• Provide Complete Disclosure: Furnish the expert with all relevant documents, including those that may not support your case, to ensure their report is balanced and robust.
• Outline Assumptions: If the expert is to make any assumptions, these should be clearly stated and justified.
• Remind of Duties: Always remind the expert of their overriding duty to the court.

FAQ (Frequently Asked Questions)

Is a single joint expert always faster than party-appointed experts?

Not always. While a single joint expert theoretically streamlines the process by consolidating instruction and reporting, disagreements between parties on instructions or expert choice can cause significant delays. Party-appointed experts, conversely, can lead to delays if multiple reports clash and require extensive reconciliation.

What are the main benefits of using a single joint expert?

The main benefits include potential for reduced costs, avoiding conflicting expert evidence, and streamlining the overall process of obtaining expert evidence, which can contribute to a faster resolution if parties co-operate effectively.

Can the court force parties to use a single joint expert?

Yes, under CPR Part 35.7, the court has the power to direct that evidence on a particular issue is to be given by a single joint expert, even if the parties would prefer to instruct their own experts.

What happens if parties cannot agree on a single joint expert?

If parties cannot agree on an SJE, the court may select the expert from a list prepared by the parties or direct that the expert be selected in another way. This typically adds time and cost to the process.

How does an expert's availability affect timeliness?

An expert's availability is crucial. Highly sought-after experts may have waiting lists, and their capacity to undertake assessments and produce reports within court deadlines can significantly impact the overall timeline, regardless of whether they are acting as an SJE or party-appointed expert.

Conclusion: Which is Faster?

In conclusion, when considering whether a single joint expert or a party-appointed expert is faster, there is no universally applicable answer. In an ideal scenario of full co-operation between parties, a single joint expert can indeed offer a faster and more cost-effective route to obtaining expert evidence by avoiding duplication and the need to reconcile competing opinions. However, this speed is contingent on the swift agreement of instructions and expert choice amongst all parties. Where such agreement is difficult to achieve, the SJE route can become protracted.

Conversely, while party-appointed experts allow individual parties more control and potentially faster initial instruction, the subsequent process of exchanging reports, holding meetings of experts, and addressing conflicting views can lead to significant delays. Ultimately, the fastest approach often depends not just on the instruction model, but also on the complexity of the case, the availability and efficiency of the chosen expert, and crucially, the degree of co-operation between the legal teams involved.
