This report looks into the PRB decisions and practices to assess the effectiveness of this institution and, above all, to see how impartial PRB is in administering justice to the parties. The period monitored for this report is 1 June – 31 December 2018, 479 decisions analyses and compared. The findings of the report indicate a lack of consistency in a number of PRB decisions that contradict previous ones. D+ has continuously highlighted the need for greater standardization of PRB decisions, in order for decisions to be reasonably predictable by parties, as a result of previous precedents. The PRB does not seem to have a methodology of referring to previous decisions, when handling complaints. Such practice could have led to a lower number of inconsistent decisions.
