Introduction

The case of Chandanmal & Ors (t/a C Narain Bros) v Revenue & Customs ([2012] UKFTT 188 (TC)) presents significant considerations regarding the admissibility and handling of expert evidence within the UK tax tribunal system. The appellants, Arjan Chandanmal, Ashok Arjandas Nainani, and Rajesh Chandanmal trading as C Narain Bros, appealed against HM Revenue and Customs (HMRC)'s decision to deny the recovery of approximately £4.7 million in input tax. The central issues revolved around allegations that the transactions in question were connected to Missing Trader Intra-Community (MTIC) fraud and whether the appellants were aware or should have been aware of these fraudulent activities.

Summary of the Judgment

The First-tier Tribunal (Tax Chamber) conducted a comprehensive hearing before determining several key procedural and substantive aspects of the appeal. The appellant's requests included staying the proceedings pending a Court of Justice of the European Union (CJEU) decision on a related case (Bonik), ensuring compliance of expert witness statements with the Civil Procedure Rules (CPR) Part 35, and excluding certain witness statements deemed to contain inadmissible opinion evidence. The Tribunal refused the stay, citing the likely timely disposition of the Bonik case and the prolonged nature of the proceedings. Crucially, the Tribunal addressed the admissibility of expert evidence, notably excluding significant portions of witness statements from Mr. Stone and Mr. Moorhead due to their opinion-based content, which did not meet the standards prescribed by CPR Part 35. The judgment also dealt with issues surrounding disclosure of confidential FCIB material and the allocation of costs related to copying and inspecting this material.

Analysis

Precedents Cited

The Tribunal referenced several key precedents to underpin its decision-making process:

• Kittel: This case delineated the standards for admissible expert evidence, emphasizing the necessity for expert witnesses to provide independent and reliable opinions.
• Mobilx: The Court of Appeal in this case clarified aspects of the Kittel criteria, reinforcing the importance of clear differentiation between fact and opinion evidence.
• Bonik C-285/11: A pending CJEU decision relevant to the appellant's case, which the Tribunal considered in its reasoning for refusing the stay of proceedings.

These precedents collectively guided the Tribunal in evaluating the admissibility and handling of expert evidence within the tax tribunal context.

Legal Reasoning

The Tribunal's legal reasoning centered on the proper treatment of expert evidence in tribunals, aligning with principles established under the CPR, particularly Part 35. Despite tribunals not being bound by CPR, the Tribunal emphasized the importance of adopting similar standards to ensure reliability and impartiality of expert testimony. The decision underscored that expert witnesses must not only possess relevant expertise but also maintain independence from the parties involved. The Tribunal meticulously analyzed the witness statements of Mr. Stone and Mr. Moorhead, identifying sections containing opinion evidence that extended beyond mere factual recounting. By excluding these sections, the Tribunal reinforced the principle that opinion evidence should only be admissible when it emanates from recognized experts and serves to elucidate complex, specialized matters beyond the Tribunal's inherent knowledge.

Impact

This judgment has profound implications for future tax tribunal proceedings:

• Enhanced Scrutiny of Expert Evidence: Tribunals may adopt more stringent criteria akin to CPR Part 35, ensuring that expert testimony is both relevant and reliable.
• Precedent for Exclusion of Opinion Evidence: The clear exclusion of non-compliant expert opinions sets a benchmark for future cases, discouraging the submission of opinion-laden witness statements without proper substantiation.
• Procedural Clarity: The Tribunal's detailed reasoning provides a roadmap for practitioners on how to prepare and present expert evidence effectively within tribunal settings.

Ultimately, the judgment fosters a more robust and transparent approach to handling expert testimony, enhancing the integrity of tax tribunal adjudications.

Complex Concepts Simplified

Civil Procedure Rules (CPR) Part 35

CPR Part 35 governs the use of expert evidence in civil proceedings. It sets out requirements for the preparation, disclosure, and admissibility of expert reports, ensuring that experts provide unbiased, independent opinions supported by their expertise.

Opinion Evidence vs. Fact Evidence

Fact Evidence: Testimony that is purely factual and describes events or information the witness has directly observed or experienced.
Opinion Evidence: Testimony where the witness provides their interpretation or assessment of facts, which may require specialized knowledge to evaluate.

Missing Trader Intra-Community (MTIC) Fraud

MTIC fraud, also known as carousel fraud, involves companies exploiting VAT rules within the European Union to reclaim VAT on goods that never actually enter the market, leading to substantial losses for tax authorities.

Hearsay Evidence

Hearsay evidence refers to statements made outside the current proceedings that are presented to prove the truth of the matter asserted. Generally, hearsay is inadmissible due to concerns about reliability, though exceptions exist.

Conclusion

The Chandanmal & Ors v Revenue & Customs judgment underscores the critical importance of stringent criteria for expert evidence within tax tribunals. By aligning with CPR Part 35 standards, the Tribunal ensured that only credible, independent, and relevant expert testimony influenced its decision-making process. This approach not only upholds the integrity of the tribunal's findings but also provides clear guidance for future cases on the preparation and submission of expert evidence. The exclusion of opinion-laden witness statements in this case serves as a pivotal reference point, promoting a more rigorous and transparent adjudicative environment within the UK's tax tribunal system.

• Expert evidence in tribunals should adhere to high standards of reliability and independence, similar to those in formal court settings.
• Distinguishing between fact and opinion evidence is essential to ensure the integrity of the tribunal's decisions.
• Tribunals have the discretion to exclude inadmissible evidence to maintain procedural fairness and judicial efficiency.
• This judgment sets a precedent for the treatment of expert witnesses, emphasizing the necessity for compliance with established procedural rules.
