Is hate speech protected by freedom of expression? Do pipeline projects require the free, prior, and informed consent of Indigenous peoples before construction may begin on their lands? What is the reach of the Parliament of Canada's authority to regulate the environment?

Why are constitutional and public law vital?

Constitutional and public law serve some of the most important functions of law in society. They constitute, restrain, and direct government authority and guarantee, secure, and vindicate human rights. Constitutional and public law regulate and mediate the relationship between the citizen and the state and its governing institutions and demarcate the roles and responsibilities of the executive, legislative, and judicial branches of government.

The division of powers between the federal Parliament and the provincial legislatures, the scope and limitation of rights and freedoms under the Canadian Charter of Rights and Freedoms, the promise of reconciliation in section 35 of the Constitution Act, 1982, and the judicial review of decisions of administrative tribunals all fall within the broad ambit of constitutional and public law.


Close to one quarter of Queen’s Law faculty research and write in the area of constitutional and public law. Between them, they bring insights from rights theory, political theory, economic analysis, feminist studies, and deep experience in the practice of law within government and private practice.
