Factual and Procedural Background
The appeal concerns an order made by Judge Ryland on 16 August 2002, which set aside an earlier order by Judge Zucker dated 27 June 2002. Judge Zucker had granted the Defendant permission to rely on an expert report dated 20 June 2002 prepared by an expert witness referred to as Mr. McLean. Judge Ryland excluded Mr. McLean’s evidence on the basis that he had previously been employed as Chief Executive of a company intimately involved in the litigation, raising concerns about the appropriateness and perceived impartiality of his evidence.
The underlying action arises from a road traffic accident on 25 January 2001 involving the Defendant's bus and the First Claimant’s vehicle. The First Claimant hired substitute vehicles from a car rental company (referred to as Swift Rent-a-Car Limited) during repairs. The First Claimant claimed hire charges, and the Defendant disputed liability and the reasonableness of the hire charges.
The case was allocated to the Fast Track, with trial directions issued and a trial date set for 27 August 2002. The Defendant sought to rely on Mr. McLean’s expert report to provide comparative hire rates for prestigious vehicles. After procedural objections and a late service of the report, Judge Ryland excluded the evidence and adjourned the matter to allow the Defendant to produce another expert report.
Legal Issues Presented
- Whether the evidence of an expert witness who has a prior connection with a party to the litigation should be excluded on grounds of independence and fairness.
- The appropriate legal test for excluding expert evidence: whether it is apparent bias, lack of independence, or the principle that justice must be seen to be done.
- The extent of the court’s discretion in case management decisions regarding expert evidence under the Civil Procedure Rules (CPR), particularly in Fast Track cases.
- The impact of recent authorities, including the Court of Appeal’s decision in Factortame (No 8), on the admissibility of expert evidence where the expert has a connection to a party.
Arguments of the Parties
Appellant's Arguments
- The Judge applied an overly stringent test based on apparent bias, which was disapproved by the Court of Appeal in Factortame (No 8).
- Mr. McLean was aware of his duty to the court and capable of giving independent expert evidence despite his previous employment with the related company.
- No material showed actual or apparent bias or ill will by Mr. McLean towards the company he had formerly worked for.
- Excluding Mr. McLean’s evidence solely because of a past connection would unduly restrict the use of expert evidence, including common experts like treating consultants.
- The expert report did not involve the business practices of the related company but focused on market hire rates, making the connection irrelevant.
- Procedural failures by the Defendant in disclosing the report late did not justify exclusion of the evidence; these could be addressed by costs orders.
Respondent's Arguments
- The Judge applied the correct test focusing on whether justice could be seen to be done, relying on established authority (Whitehouse v Jordan).
- The decision in Factortame did not undermine the Judge’s ruling, which was a proper exercise of case management discretion.
- Mr. McLean was not an independent witness as his prior role as Chief Executive of the related company gave him intimate knowledge and potential bias.
- His expert report included inappropriate commentary beyond instructions, suggesting advocacy against the related company.
- His short tenure and departure under circumstances described as incompatible with personal ambitions suggested possible animosity.
- Admitting his evidence would subvert the Fast Track procedure by necessitating oral cross-examination on personal matters, contrary to CPR 35.5(2).
- The late disclosure of the report disadvantaged the Respondents and increased costs, justifying exclusion under the overriding objective of the CPR.

Court's Reasoning and Analysis
The court recognized that Judge Ryland excluded the expert evidence on the basis that Mr. McLean’s prior role as Chief Executive of the related company rendered his evidence "tainted" and that justice could not be seen to be done if he gave evidence. This approach was effectively an application of the apparent bias test as applied to courts or tribunals.
However, the Court of Appeal’s decision in Factortame (No 8) disapproved the use of the apparent bias test for expert witnesses, emphasizing that such a test would unduly restrict expert evidence, especially when experts are employees or have connections to parties. Instead, the admissibility of expert evidence should be determined as a matter of case management, weighing the nature and extent of any interest or connection against the overriding objective of the Civil Procedure Rules.
The court analyzed Mr. McLean’s qualifications and expertise, concluding he was a leading expert in the field with relevant experience and knowledge. There was no sufficient evidence that his prior employment created actual or apparent bias, animus, or inability to comply with his duty to the court.
The court acknowledged procedural failings by the Defendant in late disclosure of the expert report, which caused disadvantage and increased costs. However, these procedural issues were not sufficient to exclude the evidence and could be addressed by costs orders.
The court also considered the fast track procedural context and the potential for oral cross-examination but concluded that exclusion was not warranted on that basis alone.
Ultimately, the court held that Judge Ryland applied the wrong legal test and that the exclusion of the expert evidence was not justified under the correct principles established in Factortame and Field.
Holding and Implications
The court ALLOWED THE APPEAL against Judge Ryland’s decision of 16 August 2002 and reinstated Judge Zucker’s order dated 27 June 2002 permitting the Defendant to rely upon the expert report of Mr. McLean dated 20 June 2002.
The direct effect is that the expert evidence of Mr. McLean is admissible in the proceedings. No new precedent was established beyond clarification that the apparent bias test applicable to judges and tribunals does not apply to expert witnesses. The case reinforces the principle that expert evidence exclusion is a matter of case management discretion, balancing expertise, independence, and procedural fairness under the Civil Procedure Rules.
