This approach was implemented to separate the government into three distinct branches in order to prevent any one branch from holding too much power.

Separation of Power approach.

Explanation:

The three powers of the government - Judiciary, Legislation, and Executive - play out the three fundamental functions of the law-making process, law-adjudication and law-application. This triple division of the government branches is generally acknowledged as the most ideal method for sorting out the government so that every branch has equal powers. These three branches are inter-dependent and inter-related with each other. In any case, these are performed by three distinct organs.
