What Is Separation of Powers?

Separation of powers is an organizational structure where responsibilities, authorities, and powers are divided between groups rather than being centrally held.

Separation of powers is most closely associated with political systems, in which the legislative, executive, and judicial powers of government are vested in separate bodies.

Key Takeaways

  • Separation of powers is an organizational structure where responsibilities, authorities, and powers are divided between groups rather than being centrally held.
  • Separation of powers is most closely associated with political systems, in which the legislative, executive, and judicial powers of government are vested in separate bodies.
  • In the U.S. and U.K. separation of powers is the tripartite system whose intent is to provide checks-and-balances for the different branches.

Understanding Separation of Powers

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. Each has distinct powers, though some states in the U.S. use the bipartite system, which assigns powers to two separate groups.

In the U.S., the powers afforded to the judicial, legislative, and executive branches are defined in the Constitution. Governmental authority is divided between the executive branch (controlled by the President), the legislative branch (controlled by Congress), and the judicial branch (controlled by the Supreme Court). For example, in the U.S., the executive branch nominates judges, the legislative branch confirms the nominations, and the judicial branch adjudicates on the constitutional merit of the laws passed by the legislature.

In business, the CEO and chair positions are often separated to prevent abuse of power.

While the separation of powers is most closely associated with politics, this type of system can also be used in other organizations. For example, there are good reasons to separate the positions of the chief executive officer (CEO) and chair, in order to increase checks and balances and give corporate governance real integrity. Because the board of directors’ main job is to oversee management on behalf of shareholders, CEOs who hold both roles are effectively monitoring themselves, which leads to potential abuses of power and reduced transparency and accountability.

Example of Separation of Powers

In 2018, Elon Musk came under increasing criticism for holding both the CEO and chair roles at Tesla, the electric vehicle and clean energy company. He made outlandish claims about the potential of Tesla’s technology, which led to concerns that Musk might be misleading investors.

After the Securities and Exchange Commission (SEC) charged Theranos with massive fraud, for deceiving investors about the company's performance, the claims made by Silicon Valley companies, both public and private, have come under greater scrutiny. As Tesla struggled to contain cost and ramp up production of its Model 3 sedans, activist investors asked the board to consider a motion to fire Musk from his chair of the board position and replace board members who lack independence from chair and CEO Elon Musk.

To ensure a separation of powers, the U.S. Federal Government is made up of three branches: legislative, executive and judicial. To ensure the government is effective and citizens’ rights are protected, each branch has its own powers and responsibilities, including working with the other branches.

OVERVIEW | SEPARATION OF POWERS

The term  "trias politica" or "separation of powers" was coined in the 18th century by Charles-Louis de Secondat, baron de La Brède et de Montesquieu. His publication, "Spirit of the Laws," is considered one of the great works in the history of political theory and jurisprudence and under his model, the political authority of the state is divided into legislative, executive and judicial powers. 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.
