The seminar examines the increasingly common situation in which to follow a rule means in practice to rewrite the rule in the light of (joint) efforts to implement it. How, if at all, can such rule-making and revision provide the various forms of accountability we associate with the rule of law? By what institutional means is such revisionary rule-making accomplished? What are its implications for our understanding of administrative and constitutional law as well as contractual agreements? These general themes will be explored in the context of case studies of the rights of first peoples, the WTO trade regime, EU governance and reform of public schools in the United States.
