Separation of powers

  • the separation of powers is a representation for the governance of a state. under this model, a state's government is divided into branches, each with separate, independent powers and responsibilities so that powers of one branch are not in conflict with those of the other branches. the typical division is into three branches: a legislature, an executive, and a judiciary, which is the trias politica model. it can be contrasted with the fusion of powers in parliamentary and semi-presidential systems, where the executive and legislative branches overlap.

    separation of powers, therefore, refers to the division of responsibilities into distinct branches of government by limiting any one branch from exercising the core functions of another. the intent of separation of powers is to prevent the concentration of power by providing for checks and balances.

    the separation of powers model is often imprecisely and metonymically used interchangeably with the trias politica principle. while the trias politica model is a common type of separation, there are governments that have greater or fewer than three branches, as mentioned later in the article.
