My research focuses on constitutional law, legal history, and legal theory. One theme that I am continuing to consider is the status of Aboriginal customary laws and government in colonial Canada. In particular, I am interested in exploring what may be labelled the ‘covenant-chain constitution' that existed in pre-confederation Canada – the covenant chain being the series of treaties that bound the Crown and Aboriginal nations in the Great Lakes region. I am also interested in some general theoretical problems arising in constitutional law, and how approaches to these problems affect approaches to practical legal issues. An example that I have been considering is the notion of the ‘unwritten' constitution. Finally, I am exploring the evolution of jurisprudential and constitutional theory. I am presently engaged in a research project involving the work of constitutional scholar Albert Venn Dicey.
