To what extent should the doctrine of the separation of powers evolve in light of recent shifts in constitutional design and practice? Constitutions now often include newer forms of rights – such as socioeconomic and environmental rights – and are written with an explicitly transformative purpose. They also often reflect include new independent bodies such as human rights commissions and electoral tribunals whose position and function within the traditional structure is novel. The practice of the separation of powers has also changed, as the executive has tended to gain power and deliberative bodies like legislatures have often been thrown into a state of crisis. The chapters in this edited volume grapple with these shifts and the ways in which the doctrine of the separation of powers might respond to them. It also asks whether the shifts that are taking place are mostly a product of the constitutional systems of the global south, or instead reflect changes that run across most liberal democratic constitutional systems around the world.

This insightful book guides readers through the transformation of, and theoretical challenges posed by, the separation of powers in national contexts. Building on the notion that the traditional tripartite structure of the separation of powers has undergone a significant process of fragmentation and expansion, this book identifies and illustrates the most pressing and intriguing aspects of the separation of powers in contemporary constitutional systems.

Each branch of American government possesses inherent advantages and disadvantages in structure. In this book, the author relies on a separation-of-powers analysis that emphasizes the advantage of the legislature to draft precise words to fit intended situations, the judiciary’s advantage of being able to do justice in an individual case, and the executive’s homogeneity and flexibility, which best suits it to decisions of an ad hoc nature. Identifying these structural abilities, the author analyzes major public policy issues, including gun control, flag burning, abortion, civil rights, war powers, suing the President, legislative veto, the exclusionary rule, and affirmative action. Each issue is examined not from the point of view of determining the right outcome, but with the intention of identifying the branch of government most appropriate for making the decision.

The principle of the separation of powers has been subject to much recent controversy. This book criticizes the various challenges raised by legal, political, public policy, and management theorists. It revisits the classic normative background of the principle and offers a novel justification of it, grounding it in analytical political theory.

Prompted by the events following the 2016 referendum on EU membership and written during the COVID-19 pandemic by one of the leading public lawyers of our day, this book considers two key constitutional principles, the rule of law and separation of powers, by examining the generality, certainty and predictability of law, relations between the different branches of the state, and the mechanisms of accountability within our democracy. Since the referendum and in the light of the restrictions imposed to deal with the pandemic, and the use of guidelines presented as rules to do so, attention has refocused on the relationship and respective powers and competences of the three branches of the state, the legislature, the executive, and the judiciary. They have also placed strains on our unwritten constitution that have been unknown in modern times. The role of the courts and of the rule of law, has been dramatically illustrated by recent litigation, most notably the decisions on whether legislation was needed to serve notice of the UK's intention to leave the EU and whether the prorogation of the Westminster Parliament in 2019 was a matter for the courts as opposed to a political question for government. Set against this backdrop, the book answers the following questions: - How accessible is the law and how does it avoid arbitrariness? - How is access to justice protected? - How does our constitution reflect the separation of powers and the balance of responsibilities between law and politics? - How does our democracy enable majorities and protect minorities?
