The separation of powers is usually understood as a constitutional doctrine that separates government into autonomous institutions responsible for performing distinct functions. The most common system separates government into legislative, executive, and judicial branches. According to this model, the legislative power creates laws, the executive power enforces laws, and the judicial power interprets laws. Each branch theoretically performs only its own function, and the individuals working within each branch should not concurrently work in another branch. The main justification for separating powers between independent branches is to prevent any individual or group from accumulating excessive power and ruling tyrannically.
