The New Separation of Powers

The separation of powers is an important principle of liberal constitutionalism. However the traditional rationale behind institutional separation can no longer govern the distribution of authority in the modern state. This book develops a new model of the separation of powers theory for the administrative state. It argues for the replacement of the traditional theory with a new model which has the potential to both enhance democratic checks and balances and to legitimize the role of administrative and regulatory bodies in the modern state. Explaining how developments in modern governance have subverted the principles originally underpinning the separation of powers the book identifies the ways in which lawyers and administrators have sought to preserve these democratic principles in particular areas. These piecemeal efforts are gathered together into a cohesive account of a radical overarching framework for institutional reform. Drawing on examples from the United Kingdom Ireland and the U.S.A. the book provides both a descriptive and prescriptive analysis of the ways in which our legal and political notions of institutional separation have so far and (more importantly) may in the future deal with the problems posed by the emergence of quasi-public administrative or regulatory agencies. Far from the traditional view of administrative agencies as a threat to democracy administrative bodies in fact can provide a valuable opportunity for reforming public governance in a way which reinforces the foundational principles of democracy.
