Concept:Separation of powers prevents the arbitrary and unchecked use of government authority.
Explanation:Montesquieu, in his book “The Spirit of the Laws,” proposed three separate branches of government: legislature, executive, and judiciary.
Each branch is given defined powers and can check the actions of the other branches.

As a result, government decisions cannot be based on personal whim or random choice.
Thus, the main purpose of separation of powers is to prevent arbitrariness in governance.
