The Separation of Powers

The point of the separation of powers is examined, and it is argued that accounts of the principle that identify liberty as the guiding purpose of the principle are flawed, the products of an unattractive account of the state. A richer understanding of the state produces a richer understanding of the principle. The second and third parts of the chapter outline such an account, reflecting on the institutional framework required by the separation of powers: the divisions and connections that the principle demands. Different state institutions are well-placed to identify different aspects of the common good and, through their differing skills and instruments, well-suited to modify the policies of the state in light of these assessments. The constitution then combines these decisions into a single state action. The chapter then considers apparent exceptions to the separation of powers.
