Key Challenges When Giving Expert Testimony on GCC Law Before International Tribunals
Introduction
International disputes continue to rise, and tribunals are increasingly required to apply foreign national laws, particularly those of developing states. When a dispute involves GCC law, expert witnesses become essential in helping arbitrators interpret and apply statutes, Sharia principles, and local regulatory frameworks. But acting as a GCC law expert in an international forum presents unique challenges — from legal-cultural complexity and language issues to maintaining impartial credibility. These challenges mirror patterns seen across other regions such as MENA, Africa, Latin America, and Asia.
Navigating GCC Legal Complexities
GCC legal systems blend civil codes with Islamic law, creating a framework that can be difficult for foreign arbitrators to understand. Sharia is embedded in all GCC constitutions, and even modern commercial laws can reflect Sharia norms, such as the prohibition of riba. Courts in some jurisdictions, like Qatar, may limit remedies such as compound interest for this reason. Experts must clarify why seemingly standard remedies might not be permitted unless expressly provided by contract.
GCC countries also differ in their application of Sharia. Saudi Arabia relies heavily on Sharia (Hanbali school), with fewer codified statutes and minimal precedent. Other GCC states (UAE, Qatar, Kuwait, Bahrain, Oman) follow civil codes influenced by Egyptian and French models, while still requiring Sharia compliance where relevant. An expert must explain the hierarchy of legal sources — constitutions, statutes, decrees, case law, and scholarly writings — and how they interact. This is often unfamiliar to arbitrators from common-law or secular legal traditions.
Explaining Sharia-derived concepts in secular arbitration is delicate. Experts must clarify that Sharia is not monolithic and that interpretations vary among GCC jurisdictions. For instance, Saudi Arabia has created specialized courts to address commercial and administrative matters where classical jurisprudence lacks detailed rules. Experts may need to testify on how modern regulations operate within a Sharia-based system, a nuance foreign arbitrators may overlook.
Because foreign law is treated as a fact in arbitration, experts bear the burden of proving and educating the tribunal on the applicable GCC rules. This often requires reconstructing legal principles from several sources and presenting them as a coherent, objective legal narrative rather than partisan advocacy.
Language and Translation Barriers
Primary GCC legal sources are typically in Arabic, while arbitration proceedings are often in English. This presents a major challenge. Accurate translation of statutes, contracts, and judgments is crucial, as mistakes can lead to misinterpretation of the law. Experts must work closely with translators, offer certified translations when necessary, and explain terms or legal concepts with no direct English equivalent.
In Saudi Arabia, the Arabic version of a contract usually prevails. Experts must therefore present the original Arabic text and highlight nuances that cannot be captured in translation. They may also need to explain culturally grounded legal idioms or evidentiary concepts, such as the significance of religious oaths or intention (niyyah) in legal interpretation.
Cultural communication styles also influence credibility. GCC legal discourse may use more formal language or moral principles unfamiliar to foreign tribunals. Experts must translate not only the words but the context. Procedural expectations differ as well: Saudi courts generally rely on court-appointed experts who are not cross-examined, whereas international arbitration involves adversarial questioning. Thus, GCC law experts must be prepared for cross-examination in English and communicate clearly under pressure. Bilingual expertise is often essential.
Maintaining Independence and Credibility
A key challenge is maintaining neutrality. Unlike national court systems with strict expert rules, most arbitral regimes impose minimal formal requirements on experts. Although soft-law guidelines encourage independence, it is ultimately up to the expert to show they are assisting the tribunal, not advocating for a party.
Experts must affirm their impartiality explicitly and ensure their reports demonstrate objective legal reasoning. Allegations of bias can arise, especially when experts opine on the laws of their own country. Some cases have included attempts to disqualify experts, though tribunals generally require strong evidence of conflict before excluding testimony.
To maintain credibility, GCC law experts should disclose any relevant relationships, explain their methodology clearly, and cite authoritative sources. A persuasive expert acknowledges uncertainty where the law is unsettled and explains competing interpretations. Ethical standards rooted in GCC legal culture — where truthfulness carries moral and religious significance — can reinforce an expert’s credibility. Ultimately, tribunals evaluate the expert’s reasoning more than the conclusion itself.
Experts must also remember that tribunals are not required to accept their interpretation of the law. Conflicting expert reports are common, and tribunals may choose one view or form their own. A calm, educational tone is more persuasive than advocacy. The best experts “teach rather than preach,” guiding the tribunal through the legal system clearly and coherently.
Global Comparisons and Trends
Challenges facing GCC law experts mirror global trends. Across Africa, frequent amendments to mining and natural resource laws have triggered arbitrations requiring expert interpretation of domestic legal frameworks. Latin America has long experienced disputes arising from regulatory reforms and nationalization measures, where tribunals rely heavily on expert testimony on local legislation and administrative law. Experts there, as in the GCC, must bridge gaps between domestic legal doctrines and international legal standards.
Similar patterns exist in the Middle East, Asia, and emerging markets generally — as large-scale projects grow, more disputes require international tribunals to apply unfamiliar national laws. Even when tribunals have the power to appoint independent experts, party-appointed experts remain the norm. Success in these cases depends on the expert’s ability to communicate complexity clearly and objectively.
Conclusion
Serving as a GCC law expert before international tribunals demands mastery of local legal systems and the ability to explain them within the adversarial structure of arbitration. Key challenges include conveying Sharia-influenced rules to arbitrators from other legal backgrounds, bridging language and translation gaps, and demonstrating independence in a system with limited formal safeguards. These difficulties parallel those seen in Africa, Latin America, and other regions, highlighting the global importance of reliable local-law experts.
By approaching testimony with clarity, neutrality, and cultural fluency, GCC law experts can ensure tribunals apply the correct legal principles and reach sound, enforceable decisions. This strengthens both the integrity of the arbitration process and the recognition of GCC laws on the international stage.
