Single Joint Expert vs Party-Appointed: Which Is Faster?

When comparing a single joint expert vs party-appoinbted expert, the appointment of a single joint expert (SJE) can often be a faster route for obtaining expert evidence in UK legal proceedings. This is primarily because it streamlines the instruction process and removes the need to reconcile differing opinions from multiple experts, thereby avoiding the delays often associated with party-appointed experts.

Understanding Expert Witness Appointment Types

In UK litigation, solicitors and legal teams frequently need expert evidence to support their client's case. The Civil Procedure Rules (CPR) and Criminal Procedure Rules (CrPR) govern the instruction and use of expert witnesses. A crucial decision in this process is whether to instruct a single joint expert or for each party to appoint their own expert. Both approaches have distinct implications for cost, complexity, and, critically, the speed of the case.

What is a Single Joint Expert (SJE)?

A single joint expert is an expert instructed by two or more parties in a civil case, typically the claimant and defendant, to provide an impartial report on specific issues. The SJE owes a duty to the court and to all instructing parties. The instruction is usually agreed upon jointly, and the expert's fees are shared between the parties. This model is generally preferred by the courts, especially in lower value claims, to save time and expense.

Key characteristics of an SJE:

• Instructed by multiple parties (e.g., claimant and defendant).
• Owes a primary duty to the court.
• Fees are typically shared.
• Provides a single report addressing all agreed questions.

The SJE model aligns with the overriding objective of the CPR: 'to enable the court to deal with cases justly and at a proportionate cost'. For more information on expert duties, see gov.uk guidance on expert witnesses.

What is a Party-Appointed Expert?

Conversely, a party-appointed expert is instructed by one party only, such as the claimant or the defendant, to provide evidence that supports their specific legal position. Each party might appoint their own expert in the same field, leading to potentially two or more expert reports on similar issues. While these experts also owe a duty to the court, their instruction originates from and is funded by a single party.

Key characteristics of a party-appointed expert:

• Instructed by a single party.
• Owes a primary duty to the court, but is engaged by one side.
• Fees are paid by the instructing party.
• Each party receives their own report.

Timeline Considerations for SJE Appointment

The process for appointing a single joint expert can be inherently quicker for several reasons:

1. Single Instruction Process: Instead of two or more distinct instruction processes, there is only one. Solicitors from opposing sides communicate to agree on the expert, the letter of instruction, and the questions to be put to the expert. While this initial agreement can take time, it avoids duplicated administrative effort.
2. One Expert's Availability: Finding one expert who is available and suitable can be faster than finding two separate experts who meet each party's criteria and can work to similar timelines.
3. Unified Reporting: The SJE produces a single report. There is no need for back-and-forth correspondence, meetings, or joint statements between multiple experts to reconcile differing opinions, which is a common source of delay with party-appointed experts. The SJE's report is then circulated to all instructing parties concurrently.
4. Reduced Scope for Disputes on Evidence: Since the SJE's duty is to the court, their evidence is less likely to be perceived as biased by either side. This can reduce challenges to the expert's methodology or conclusions, potentially shortening the duration of the expert evidence phase.

However, it's important to note that if parties cannot agree on an SJE or the questions to be asked, this initial stage can introduce delays. Once agreement is reached, the subsequent stages generally proceed more quickly.

Timeline Considerations for Party-Appointed Experts

The party-appointed expert model can introduce more variable and potentially longer timelines:

1. Duplicate Instruction Processes: Each party must independently identify, instruct, and brief an expert. This means separate administrative tasks and schedules for two or more experts.
2. Multiple Experts' Availability: Coordinating the availability of two busy experts, who may have differing commitments, can be challenging and lead to delays, especially if they need to inspect the same site or person.
3. Joint Statements and Meetings: A common requirement under CPR Part 35 is for party-appointed experts to meet and prepare a joint statement identifying agreed issues and disagreements. This process can be time-consuming, requiring significant coordination between experts and their instructing solicitors. Resolving points of disagreement or simply arranging the meeting itself can cause significant delays.
4. Potential for Contesting Expert Evidence: Where experts' opinions differ significantly, there may be applications to the court for permission to adduce further expert evidence or to cross-examine experts extensively at trial. These steps add considerable time to the litigation process.

Impact on Case Progress

The choice between a single joint expert vs party-appoinbted expert has direct implications for the overall speed of the legal process. In civil cases, courts actively encourage parties to consider an SJE to manage costs and avoid unnecessary delays. This preference is codified in CPR 35.7, which states that the court may direct that expert evidence be given by one expert only. For a firm understanding of expert witness duties, refer to The Civil Procedure Rules Part 35.

• Single Joint Expert (SJE): Tends to foster earlier resolution and requires less court management time. Once appointed, the SJE's report often becomes a central, undisputed piece of evidence, facilitating settlement discussions or a more streamlined trial.
• Party-Appointed Experts: Can lead to 'battles of experts', requiring greater court intervention to manage disagreements and often leading to increased trial duration if experts need to be cross-examined on their differing views. This can prolong the overall case timeline significantly.

Considerations Beyond Speed

While speed is a critical factor, other considerations influence the choice of expert appointment. These include:

• Cost: SJEs are usually more cost-effective as fees are shared and there is only one expert's time to pay for. Party-appointed experts mean each party bears their own expert's costs, which can be substantial.
• Control over Instruction: With party-appointed experts, each solicitor has full control over their expert's instructions and the specific questions asked. In an SJE scenario, instructions must be agreed upon jointly, which can sometimes be a point of contention for parties with fundamentally opposing views.
• Nature of the Dispute: In highly complex or high-value cases where specialist and nuanced opinions are crucial, or where there are profound disagreements on core technical issues, parties may opt for party-appointed experts to ensure their specific arguments are fully explored.
• Impartiality Perception: SJEs are seen as inherently more impartial given their joint instruction and direct duty to the court, which can lend more weight to their findings.

Finding the Right Expert, Fast

Regardless of whether a single joint expert or party-appointed expert is required, securing a suitably qualified professional quickly is paramount, particularly under tight court deadlines. For an SJE, finding an expert acceptable to all parties requires careful consideration of their independence, qualifications, and experience. For party-appointed experts, the focus is on finding an expert who can robustly support a specific legal position, whilst still adhering to their duty to the court.

FAQ

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

Generally, yes. A single joint expert (SJE) streamlines the instruction process and removes the need for experts to reconcile differing opinions, which saves significant time. However, delays can occur if parties struggle to agree on the SJE or the questions to be asked initially.

Can I still challenge a single joint expert's report?

Yes, you can. While an SJE provides a single report, parties are able to submit written questions to clarify points or explore aspects left unclear, as per CPR Part 35. You may also seek permission from the court to instruct your own expert if there are strong grounds to challenge the SJE's methodology or conclusions.

When would party-appointed experts be preferred over an SJE?

Party-appointed experts might be preferred in complex or high-value cases where parties have fundamentally divergent technical positions, or where a highly specialised opinion is required to substantiate nuanced arguments. It also offers greater control over the initial instruction process for each party.

How does the court decide if an SJE should be used?

The court typically considers the nature of the issue, the amount in dispute, costs, and the overall overriding objective of dealing with cases justly and proportionately. CPR 35.7 encourages the use of an SJE and the court can direct this even if parties initially want to appoint their own experts.

To summarise, when considering a single joint expert vs party-appointed expert, the single joint expert route often facilitates a faster resolution by simplifying the expert evidence stage. This efficiency can be crucial for meeting court deadlines and progressing cases expeditiously.
