What is the role of participatory rights in procedural fairness?

In Baker v. Canada (Minister of Immigration and Citizenship), supra, L’Heureux-Dubé commented on the nature of participatory rights as part of the duty of procedural fairness. She stated (at para. 22): Although the duty of fairness is flexible and variable, and depends on an appreciation of the context of the particular statute and the rights affected, it is helpful to review the criteria that should be used in determining what procedural rights the duty of fairness requires in a given set of circumstances. I emphasize that underlying all these facts is the notion that the purpose of participatory rights contained within the duty of procedural fairness is to ensure that administrative decisions are made using a fair and open procedure, appropriate to the decisions being made and its statutory, institutional, and social context, with an opportunity for those affected by the decision to put forward their views and evidence fully and have them considered by the decision-maker.
