Linguistic Competence in Arbitration: A Foundation for Equity and Efficiency

This article examines the indispensable role of linguistic competence in securing procedural fairness and efficiency within multilingual arbitration. Through doctrinal analysis of landmark arbitral awards and comparative cross-jurisdictional case studies, it demonstrates how translation errors, cultural misinterpretations, and proficiency gaps erode due process and award legitimacy. Integrating insights from sociolinguistics, cognitive science, and computational linguistics, the study develops a unifying framework linking arbitrators’ intercultural communication skills and metalinguistic awareness to enhanced access to justice and procedural integrity. Empirical examples illustrate three core procedural safeguards: (1) mandatory intercultural communication training for arbitrators; (2) standardized prehearing translation and interpretation protocols (including glossaries, back-translation checks, and certified translator rosters); and (3) selective deployment of AI-assisted translation tools under strict human oversight. The article further advocates institutional reforms—establishing minimum linguistic competence benchmarks and promoting multilingual arbitration panels—to embed these safeguards into arbitral practice. By situating these recommendations within Sustainable Development Goals 4 (Quality Education), 9 (Industry, Innovation and Infrastructure), and 16 (Peace, Justice and Strong Institutions), the study underscores how strengthening linguistic competence advances global commitments to education, innovation, and equal access to justice. In doing so, it positions linguistic competence not merely as a procedural enhancement but as a transformative force that aligns arbitration with broader principles of equity and efficiency in the global legal landscape.
