What is the current state of the law on adjournment of administrative proceedings?

In Siloch v. Canada (Minister of Employment and Immigration), supra, at paragraph 3, Décary J.A. recalled the same general rule: It is well settled that in the absence of specific rules laid down by statute or regulation, administrative tribunals control their own proceedings and that adjournment of their proceedings is very much in their discretion, subject to the proviso that they comply with the rules of fairness and, where they exercise judicial or quasi-judicial functions, the rules of natural justice.
