The Separation of Powers – Why Is It Necessary?

The separation of powers is a model for the governance of a state. Under this model, a state's government is divided into branches, each with separate and independent powers and areas of responsibility so that the powers of one branch are not in conflict with the powers associated with 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 systems and semi-presidential systems where the executive and legislative branches overlap. Separation of powers, therefore, refers to the division of responsibilities into distinct branches to limit any one branch from exercising the core functions of another.

The United States just endured a monthlong government shutdown affecting services ranging from airline travel to tax collection. Congress and the president have battled over where and even whether to hold the State of the Union. Plus, late last year, a federal judge blocked the Trump administration from enforcing new immigration policies that would limit migrants to seeking asylum at established border checkpoints. Of course, clashes between the branches of government are nothing new. Indeed, they are actually baked into our constitutional design. But given the breakdowns in functioning within all three branches, it might appear that the separation of powers system is broken or unbalanced.

The Constitution nowhere contains an express injunction to preserve the boundaries of the three broad powers it grants, nor does it expressly enjoin maintenance of a system of checks and balances. Yet, it does grant to three separate branches the powers to legislate, to execute, and to adjudicate, and it provides throughout the document the means by which each of the branches could resist the blandishments and incursions of the others. The Framers drew up our basic charter against a background rich in the theorizing of scholars and statesmen regarding the proper ordering in a system of government of conferring sufficient power to govern while withholding the ability to abridge the liberties of the governed. When the colonies separated from Great Britain following the Revolution, the framers of their constitutions were imbued with the profound tradition of separation of powers, and they freely and expressly embodied the principle in their charters. The doctrine of separation of powers, as implemented in drafting the Constitution, was based on several generally held principles: the separation of government into three branches, legislative, executive, and judicial; the conception that each branch performs unique and identifiable functions that are appropriate to each; and the limitation of the personnel of each branch to that branch, so that no one person or group should be able to serve in more than one branch simultaneously. To a great extent, the Constitution effectuated these principles, but critics objected to what they regarded as a curious intermixture of functions, in, for example, the veto power of the President over legislation and to the role of the Senate in the appointment of executive officers and judges and in the treaty-making process.

An incomplete sketch

His publication, Spirit of the Laws , is considered one of the great works in the history of political theory and jurisprudence, and it inspired the Declaration of the Rights of Man and the Constitution of the United States. Under his model, the political authority of the state is divided into legislative, executive and judicial powers. He asserted that, to most effectively promote liberty, these three powers must be separate and acting independently. Separation of powers, therefore, refers to the division of government responsibilities into distinct branches to limit any one branch from exercising the core functions of another. The intent is to prevent the concentration of power and provide for checks and balances. California illustrates this approach; "The powers of state government are legislative, executive, and judicial. Persons charged with the exercise of one power may not exercise either of the others except as permitted by this Constitution.

The separation of powers is an organizational structure in which responsibilities, authorities and powers are divided between groups rather than being centrally held. It is most closely associated with political systems, in which the legislative, executive and judicial powers of government are vested in separate bodies. Separation of powers refers to the division of powers into distinct branches of government, each with their own responsibilities. The intent of separation of powers is to prevent the concentration of unchecked power and to provide for checks and balances , in which the powers of one branch of government is limited by the powers of another branch — to prevent abuses of power and avoid autocracy. The most well-known example of separation of powers is the tripartite system found in the United States and the United Kingdom, in which there are three individual branches of government: the executive branch, the legislative branch and the judicial branch.
