 Some procedural requirements are also institutional in character: there must be courts and there must be judges whose independence of the other branches of government is guaranteed. This side of the Rule of Law is connected with the constitutional principle of the separation of powers. That principle is sometimes justified simply on the ground that it is unhealthy for power to be institutionally concentrated in society. But it also has a Rule of Law justification inasmuch as it assigns distinct significance to distinct stages in the making and application of laws (Waldron 2013).
