The legal architecture of the Arab world is uniquely enriched by dual legal traditions. While mainland jurisdictions predominantly derive their substantive civil and commercial codes from the Romano-Germanic (French) civil law tradition—harmonized with Islamic jurisprudence (Shari'a)—specialized financial free zones operate under common law frameworks inspired by English law.
1. Fundamental Methodological Differences
In mainland civil law jurisdictions, statutory codification serves as the paramount source of law. Judges function through deductive statutory interpretation, applying comprehensive legislative texts to specific factual matrices without being strictly bound by judicial precedent (stare decisis).
Conversely, financial free zone courts—such as the Dubai International Financial Centre (DIFC) Courts and Abu Dhabi Global Market (ADGM) Courts—utilize an adversarial system grounded in binding appellate precedent and common law statutory interpretation.
2. Harmonization and Cross-Court Execution
The interaction between these two distinct legal paradigms has catalyzed unprecedented judicial cooperation. Memoranda of understanding and reciprocal enforcement protocols facilitate the seamless execution of judgments and orders across mainland civil courts and free-zone common law courts.
This hybrid environment provides international corporations and investors with choice-of-law flexibility while maintaining robust constitutional certainty.
