The study presents a comparative analysis of mediation and tribunal adjudication in resolving administrative and service disputes, emphasizing efficiency, accessibility, and fairness. Using doctrinal and qualitative approaches across jurisdictions such as India, Australia, the United Kingdom, and Singapore, the research examines procedural structures, procedural hurdles, lacunas, and institutional efficiency. Findings reveal that mediation promotes flexibility, cost-effectiveness, and higher compliance, while tribunals ensure legal consistency and enforceability. The study recommends hybrid frameworks integrating pre-litigation mediation with tribunal adjudication, supported by technological innovation and legislative reform, to strengthen administrative justice systems and enhance procedural efficiency globally.
