KHALDOUN TABARI v TABARAK INVESTMENT [2019] DIFC CFI 061 — procedural denial of expert evidence (14 February 2019)

The DIFC Court of First Instance maintains strict control over the introduction of expert testimony, emphasizing that the court itself remains the final arbiter of legal interpretation.

Why did Tabarak Investment LLC file Application No. CFI-061-2018/2 against Khaldoun Tabari and Zeina Tabari?

The dispute arises from the underlying proceedings in CFI-061-2018, where the Claimants, Khaldoun Tabari and Zeina Tabari, are engaged in litigation against the Defendant, Tabarak Investment LLC. The specific procedural friction point emerged when the Defendant sought to introduce external legal expert evidence into the record. By filing Application No. CFI-061-2018/2 on 11 February 2019, the Defendant aimed to bolster its position by providing the Court with an independent legal opinion on matters central to the dispute.

The stakes involve the evidentiary framework governing the litigation. In complex commercial disputes within the DIFC, the introduction of expert evidence is not a matter of right but a matter of judicial discretion. The Defendant’s attempt to bring in this evidence suggests a strategic effort to influence the Court’s interpretation of the governing law or the specific contractual obligations at the heart of the Tabari-Tabarak relationship. The denial of this application signifies the Court's preference for maintaining its own interpretative autonomy over the legal issues presented in the case.

Which judge presided over the 14 February 2019 order in CFI-061-2018 regarding the admissibility of expert evidence?

H.E. Justice Ali Al Madhani presided over this matter in the DIFC Court of First Instance. The order was issued on 14 February 2019, following a review of the Defendant’s application submitted just three days prior. The decision reflects the Court's active case management role, ensuring that proceedings remain focused on the core issues without the unnecessary introduction of extraneous expert testimony that might otherwise complicate or delay the adjudication process.

What arguments did Tabarak Investment LLC advance to justify the introduction of legal expert evidence in CFI-061-2018?

While the formal pleadings of the parties are contained within the confidential case file, the Defendant’s Application No. CFI-061-2018/2 was predicated on the necessity of providing the Court with specialized legal insight. Typically, in such applications, a party argues that the legal questions at hand require a nuanced understanding of specific regulatory or jurisdictional frameworks that go beyond the standard judicial notice of the law. The Defendant sought to persuade H.E. Justice Ali Al Madhani that the expert evidence was not merely helpful, but essential for a just determination of the claims brought by Khaldoun and Zeina Tabari.

Conversely, the Claimants’ position, which the Court ultimately favored, likely centered on the principle that the Court is the master of the law. Under the DIFC procedural regime, parties are generally discouraged from "outsourcing" legal interpretation to experts, as this can lead to the "battle of the experts" phenomenon, which often obscures rather than clarifies the legal issues. By denying the application, the Court effectively signaled that the legal arguments presented by the parties' counsel were sufficient for the Court to reach a decision without the intervention of a legal expert.

What was the precise doctrinal issue regarding the admissibility of legal expert evidence that H.E. Justice Ali Al Madhani had to resolve?

The core doctrinal issue was whether the Court should permit the introduction of legal expert evidence to assist in the interpretation of the law governing the dispute between the Tabari claimants and Tabarak Investment LLC. The Court had to determine if the proposed evidence fell within the permissible scope of expert testimony under the Rules of the DIFC Courts (RDC). Specifically, the Court had to weigh the probative value of the proposed expert opinion against the fundamental principle that the Court is the sole authority on the interpretation and application of the law.

This issue touches upon the boundary between factual evidence—where experts are frequently utilized—and legal argument, which is the exclusive domain of the Court and the legal representatives. The Court had to decide if the Defendant’s application crossed this boundary, potentially usurping the judicial function. By denying the application, the Court reaffirmed that legal experts are not to be used as a vehicle for parties to present their legal arguments in the guise of expert testimony.

How did H.E. Justice Ali Al Madhani apply the principles of case management to the Defendant's request?

H.E. Justice Ali Al Madhani exercised his discretion under the RDC to maintain the integrity of the trial process. The reasoning process involved a review of the application against the backdrop of the existing case file. The judge determined that the introduction of the requested legal expert evidence was not warranted, effectively concluding that the Court possessed the necessary tools and expertise to resolve the legal questions without external assistance.

The decision reflects a strict adherence to the principle that the Court’s role is to determine the law, and that expert evidence should be limited to technical or factual matters that are outside the common knowledge of the judge. By denying the application, the Court ensured that the proceedings remained streamlined and that the focus remained on the arguments presented by the parties' counsel.

Which specific Rules of the DIFC Courts (RDC) govern the admissibility of expert evidence in the DIFC Court of First Instance?

The admissibility of expert evidence in the DIFC is primarily governed by Part 31 of the Rules of the DIFC Courts (RDC). RDC 31.1 provides the Court with the power to restrict expert evidence, stating that "no party may call an expert or put in an expert’s report without the Court’s permission." Furthermore, RDC 31.2 emphasizes that expert evidence should be restricted to that which is "reasonably required to resolve the proceedings."

In this case, H.E. Justice Ali Al Madhani applied these rules to determine that the Defendant’s request did not meet the threshold of being "reasonably required." The Court’s authority to manage the evidence is absolute, and the denial of the application demonstrates the Court’s willingness to exercise this power to prevent the unnecessary expansion of the evidentiary record.

How does the decision in CFI-061-2018 align with the broader DIFC jurisprudence on the role of the Court as the final arbiter of law?

The decision aligns with established DIFC precedents that emphasize the Court’s independence in legal interpretation. While the DIFC Courts frequently engage with complex international and local laws, they consistently hold that the judge is the ultimate authority. By denying the application in CFI-061-2018, the Court reinforced the precedent that legal expert evidence is rarely, if ever, appropriate for the interpretation of the law itself.

This approach is consistent with the practice in other common law jurisdictions, where the "expert" is expected to provide evidence on facts, not to instruct the judge on the law. The Court’s decision serves as a reminder to practitioners that attempting to introduce legal expert evidence to influence the Court’s legal reasoning is a strategy that is unlikely to succeed and may be viewed as an attempt to circumvent the traditional adversarial process.

What was the final disposition of Application No. CFI-061-2018/2 and how were the costs handled?

The final disposition of the application was a straightforward denial. H.E. Justice Ali Al Madhani ordered that the Defendant’s request to adduce legal expert evidence be rejected in its entirety. Regarding the financial consequences of this procedural motion, the Court ordered that "costs shall be costs in the case." This means that the costs associated with the application will be determined at the conclusion of the main proceedings, depending on the final outcome of the litigation between the Tabari claimants and Tabarak Investment LLC.

What are the practical takeaways for practitioners regarding the use of legal expert evidence in the DIFC?

Practitioners must anticipate that the DIFC Court of First Instance will maintain a high barrier for the admission of expert evidence, especially when that evidence pertains to legal interpretation. The denial of the application in this case serves as a warning that parties should rely on their own counsel to present legal arguments rather than seeking to introduce external legal experts.

Litigants should be prepared to justify the necessity of any expert evidence by demonstrating that it addresses a specific, technical, or factual issue that is beyond the Court’s expertise. If an application for expert evidence is perceived as an attempt to introduce legal opinion, it is highly likely to be denied. Practitioners should focus their efforts on robust legal submissions rather than attempting to supplement the Court’s legal knowledge with external reports.
