XVIII Moot Madrid International Arbitration and Commercial Law Competition

International commercial arbitration emerged in the twentieth century as the dominant mechanism for resolving cross-border business disputes, offering parties a neutral forum, enforceable awards, and procedural flexibility that national courts often could not match. Its modern legal architecture rests on the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, ratified by over 170 states, together with the UNCITRAL Model Law on International Commercial Arbitration (1985, amended 2006) and the UNCITRAL Arbitration Rules. Major institutions such as the ICC International Court of Arbitration in Paris, the LCIA in London, the SCC in Stockholm, the SIAC in Singapore, the HKIAC in Hong Kong, and Madrid's own CIAM-CIAR administer thousands of cases annually under these frameworks. The core debates in the field concern the balance between party autonomy and mandatory norms, the legitimacy of investor-state arbitration under instruments such as the ICSID Convention and bilateral investment treaties, and the procedural integrity of proceedings in areas like third-party funding, arbitrator independence, and the production of evidence under the IBA Rules. Recent years have seen reform pressure from the EU following the CJEU's Achmea and Komstroy judgments, which curtailed intra-EU investment arbitration, and from UNCITRAL Working Group III, which is negotiating systemic ISDS reform including a possible standing investment court. Today arbitration faces simultaneous expansion and scrutiny: caseloads at leading institutions remain at record highs, while practitioners debate transparency, diversity on tribunals, the use of expedited and emergency procedures, the impact of sanctions on enforceability, and the integration of technology and remote hearings normalised after the COVID-19 pandemic. Moot Madrid traditionally centres its problem on a CISG sales dispute resolved under a major set of arbitration rules, requiring delegates to argue both procedural questions of jurisdiction and substantive questions of international sales law.

International commercial law governs the contracts, payments, transport, and dispute resolution mechanisms that underpin cross-border trade. Its modern foundations were laid in the postwar period through institutions such as UNCITRAL, established in 1966, and UNIDROIT, founded in 1926, which have produced a layered body of uniform law. The cornerstone instrument is the 1980 United Nations Convention on Contracts for the International Sale of Goods (CISG), now in force in over 95 states and applicable by default to most international sales contracts among parties in contracting states. Alongside it sit the UNIDROIT Principles of International Commercial Contracts, the Incoterms rules of the ICC, and conventions on carriage of goods such as the Hague-Visby, Hamburg, and Rotterdam Rules. The field's enduring tensions involve harmonisation versus diversity: civil law and common law traditions continue to interpret core concepts such as good faith, fundamental breach, and the passing of risk in divergent ways, even under ostensibly uniform texts. Soft law instruments and model contracts have proliferated to fill gaps, while digitalisation has prompted UNCITRAL's Model Law on Electronic Transferable Records (2017) and ongoing work on the use of artificial intelligence and smart contracts. Sanctions regimes, export controls, and ESG-related due-diligence obligations — including the EU Corporate Sustainability Due Diligence Directive — increasingly intersect with classical contract questions. Moot Madrid's commercial-law dimension typically requires delegates to apply the CISG to disputes involving conformity of goods, avoidance, damages, and the interaction between the Convention and domestic gap-fillers, often referencing the UNIDROIT Principles. Current debates among scholars and practitioners concern the CISG's reach over software and digital content, the treatment of hardship and force majeure after the pandemic and the war in Ukraine, and the relationship between commercial obligations and emerging supply-chain regulation.
