權力分立
Separation of powers also promotes the efficiency and competence in allocating powers by "[fitting] form to function by matching tasks to the most suitable body". Specialization of the functions and roles of the various branches helps to promote efficiency as each branch of government has specific tasks and goals that it can work towards. After all, one of the main aims of this measure is to ensure that society's goals are met, and this can be done through an efficient system of government. Lastly, separation of powers helps to enhance democratic responsibility. With the various branches of government being responsible for specific functions, people are more inclined to vote into Parliament (which will form part of the legislature) persons who will best represent their views.
