Due process is the means by which ethical constraints are placed on administrative decision-making. I have developed a model of variation in due process and use this model to explore the implementation of “due process” norms by three standard-setting bodies that are created, funded, and overseen by the Canadian Institute of Chartered Accountants – the Accounting Standards Board, the Auditing and Assurance Standards Board, and the Public Sector Accounting Standards Board. I conducted two analyses: a comparative analysis of the implementation (...) of due process norms based on differences among the three cases; and, a critique of the due process norms followed by these boards based on their internal logic and a set of best practices identified in other contexts for due process by standard setters. I have presented evidence that due process norms are more fully developed, where standards are enforced by the state and the heterogeneity of users is greatest. (shrink)
