بازاندیشی در معیار بی‌طرفی و استقلال داور اختصاصی

Introduction
Arbitration, as a highly effective ADR mechanism, is fundamentally predicated upon the impartiality and independence of the arbitrators. The right to select a party-appointed arbitrator affirms the parties' autonomy, enabling them to choose an individual competent in terms of expertise, legal culture, and familiarity with the subject matter. While competence is key, it is recognized that parties will seek to nominate an individual with some degree of inclination or empathy towards their position; an alignment often based on shared legal philosophy or industry understanding rather than improper partiality. This raises the central question in three-member arbitrations: Should party-appointed arbitrators (PNAs) be held to the identical standards of impartiality and independence as the presiding arbitrator? Two dominant views exist: The Value-Based View (UNCITRAL Model Law, European systems) emphasizes absolute impartiality for all, viewing any bias as a threat to integrity due to the adjudicative nature of the role, treating any PNA as a "private judge" from the moment of appointment. The Pragmatic View (American law) argues that the panel's purpose is to achieve balance through arbitrators somewhat aligned with the parties’ positions. This approach holds that requiring absolute impartiality from party-appointed arbitrators negates the benefit of the three-member structure—ensuring that each party’s arguments are thoroughly understood and forcefully articulated during deliberations, acting as a guarantor of a complete hearing within the panel itself. The existing research lacks a comprehensive comparison of standards applied to sole versus joint arbitrators. This study aims to examine the criteria for impartiality and independence of the party-appointed arbitrator in light of these dual approaches, determine their analytical foundations, and assess the feasibility of accepting a different, more flexible criterion for party-appointed arbitrators despite the prevailing standard of uniformity.
Methods
This research employed a descriptive-analytical method involving a thorough review of relevant laws and legal ideas. The primary sources included international and national arbitration laws (UNCITRAL Model Law, national statutes), institutional arbitration rules (ICC, LCIA, and AAA), and pertinent legal doctrine concerning arbitrator ethics and criteria. The research structure first involved an introductory discussion of the mechanism of appointing a party-appointed arbitrator and its relationship with party autonomy. This was followed by a comprehensive review of how different legal systems address the criteria of impartiality and independence for these arbitrators. The analytical foundations supporting the value-based and pragmatic perspectives were scrutinized and compared, including an assessment of the risks (such as award annulment or challenges to enforcement) associated with each approach. Finally, practical examples illustrating different standards and methods for managing and adjusting the alignment of party-appointed arbitrators—such as the role of robust disclosure—were examined to draw practical conclusions. The comparison of theoretical foundations and practical outcomes guided the final analytical conclusions.
Results and Discussions
Analysis reveals a strong prevalence of the value-based view in international frameworks, which requires identical standards of impartiality and independence for all panel members, citing the arbitrator's judicial function. This uniform standard is favored for its clarity and the perceived lower risk of challenges to the award's legitimacy in enforcement proceedings. However, the pragmatic view holds that reasonable alignment (often termed "non-neutrality" in US domestic arbitration) is inherent and acceptable for party-appointed arbitrators, provided it does not escalate to overt bias or a lack of objective judgment. This distinction is critical: "reasonable alignment" refers to an intellectual predisposition, whereas "overt bias" implies a closed mind or a failure to weigh evidence objectively. Rules by the AAA in domestic arbitration explicitly permit party-appointed arbitrators to lack strict neutrality, acknowledging the practical need for a panel member attuned to a party’s case, provided this status is fully disclosed to all parties beforehand. The study concludes that strictly applying the same high standard of impartiality to party-appointed arbitrators as to the presiding arbitrator can undermine the fundamental purpose of the three-member panel—the guarantee of effective internal advocacy for each party’s position. The pragmatic view posits that the Chair benefits from this internal advocacy, as it ensures the final decision has considered the strongest possible articulation of both sides. The presence of a demonstrably independent and impartial joint arbitrator (the Chair) is a critical safeguard that structurally ensures fairness in the final award; the Chair acts as the fulcrum, ensuring that the PNA's alignment does not corrupt the deliberative process but merely informs it. Therefore, the acceptance of reasonable alignment for party-appointed arbitrators, while maintaining the absolute standard of independence (no financial, professional, or personal ties), is a beneficial approach. It contributes to the formation of a proportionate arbitration panel and ultimately increases the quality of proceedings by guaranteeing that each party’s arguments are thoroughly scrutinized and presented during the panel’s deliberations.
Conclusion
This research concludes that while the standard of absolute independence must be uniformly applied to all arbitrators, a slight differentiation regarding the standard of impartiality for party-appointed arbitrators is both inevitable and desirable. By allowing for a degree of "reasonable alignment" (short of actual bias or a failure to disclose, and provided the PNA continues to engage judicially with the evidence and arguments), the arbitration process successfully balances the value-based need for integrity with the pragmatic need for effective representation within the panel. Adopting this differentiated standard, which relies heavily on the robust impartiality of the Chair as the ultimate guarantor of fairness, will enhance the quality of deliberation and reinforce the parties' confidence in the panel's ability to thoroughly understand and adjudicate their complex dispute. This nuanced approach recognizes the practical reality of party appointments while refusing to compromise the essential structural integrity required for a just outcome.
