The binding legal principle established is that under Section 51 of the Police Act [Chapter 11:10] and Part V of the Police Regulations of 1965, the Police Service Commission is entitled to determine appeals against discharge on the basis of written submissions without conducting oral or public hearings. The Commission's statutory function is to ensure that procedural fairness has been observed in the disciplinary and discharge process, and this can be fulfilled through examination of the written record. Natural justice does not require oral hearings at the appellate stage where the appellant was afforded a fair hearing at the trial and board of inquiry stages, and where the regulations prescribe a paper-based appeal process.
