Constitutional change is fundamental to understanding a constitutional order. On the one hand, constitutional change involves the foundational questions of a political community. Should we create a new constitution? Should we change our constitution? What is the relationship between constitution, state and people? On the other hand, the mechanisms for constitutional change are highly relevant to an assessment of where power lies within the constitutional order. Constitutional actors are enhanced or diminished with reference to their ability to secure constitutional change. This panel relates these two dimensions of constitutional change through a series of papers. Li-kung Chen and Oran Doyle explore foundational moments of constitutional change. Mikolaj Barczentewicz takes an analytical approach to the concept of a legal power to change the Constitution. David Kenny explores how political actors interact with the formal rules for constitutional change.
