Navigating the Tension between Formal Authority and Perceived Authoritativeness in Third-Party Settlement Proposals: Implications for Legitimacy and Procedural Justice in ADR and ODR

Abstract

Third-party settlement proposals—ranging from mediator proposals and judicial settlement conferences to evaluative mediation and technology-enabled recommendations—are now a routine feature of contemporary dispute resolution. Yet these interventions often trigger a recurring legitimacy problem: disputants may comply with a proposal because of formal authority (the legally or institutionally conferred power attached to an office or procedure) while simultaneously doubting the perceived authoritativeness of the proposer (the socially recognized credibility grounded in expertise, integrity, neutrality, and trustworthy motives). This paper argues that the long-term effectiveness of third-party proposals depends less on the mere presence of formal authority and more on whether the proposal is produced and communicated in ways that satisfy procedural justice expectations, thereby generating durable legitimacy. Building on interdisciplinary literature on authority, legitimacy, and procedural justice, and on mediation ethics and emerging governance frameworks for online dispute resolution (ODR), the paper offers (i) a clarified conceptual vocabulary that reduces terminological ambiguity; (ii) a compact framework that explains when proposals are experienced as coercive, paternalistic, or fair; and (iii) practical design principles for practitioners and institutions. These principles focus on role clarity, consent, transparency of reasons, participatory opportunities, safeguards against power imbalance, and contestability—especially where algorithmic tools shape settlement recommendations. The analysis concludes that legitimacy in third-party settlement proposals is best understood as an outcome of aligning formal authority with perceived authoritativeness through procedurally just practices. This alignment improves compliance, perceived fairness, and the sustainability of agreements across both traditional ADR and digitally mediated environments.
