WHAT IS SEPARATION OF POWERS?
If we heard such term, the ideas that first come to our mind are the three important branch of our government, to wit: the EXECUTIVE, the LEGISLATIVE and the JUDICIARY. However, The Supreme Court, has defined The separation of powers in one of its decision, in a more broader and wider definiton thus:
The separation of powers is a fundamental principle in our system of government.
It obtains not through express provision but by actual division in our Constitution. Each department of the government has exclusive cognizance of matters within its jurisdiction, and is supreme within its own sphere. But it does not follow from the fact that the three powers are to be kept separate and distinct that the Constitution intended them to be absolutely unrestrained and independent of each other. The Constitution has provided for an elaborate system of checks and balances to secure coordination in the workings of the various departments of the government.
For example, the Chief Executive under our Constitution is so far made a check on the legislative power that this assent is required in the enactment of laws. This, however, is subject to the further check that a bill may become a law notwithstanding the refusal of the President to approve it, by a vote of two-thirds or three-fourths, as the case may be, of the National Assembly. The President has also the right to convene the Assembly in special session whenever he chooses. On the other hand, the National Assembly operates as a check on the Executive in the sense that its consent through its Commission on Appointments is necessary in the appointments of certain officers; and the concurrence of a majority of all its members is essential to the conclusion of treaties. Furthermore, in its power to determine what courts other than the Supreme Court shall be established, to define their jurisdiction and to appropriate funds for their support, the National Assembly controls the judicial department to a certain extent. The Assembly also exercises the judicial power of trying impeachments. And the judiciary in turn, with the Supreme Court as the final arbiter, effectively checks the other departments in the exercise of its power to determine the law, and hence to declare executive and legislative acts void if violative of the Constitution.

But in the main, the Constitution has blocked out with deft strokes and in bold lines, allotment of power to the executive, the legislative and the judicial departments of the government. The overlapping and interlacing of functions and duties between the several departments, however, sometimes makes it hard to say just where the one leaves off and the other begins. In times of social disquietude or political excitement, the great landmarks of the Constitution are apt to be forgotten or marred, if not entirely obliterated. In cases of conflict, the judicial department is the only constitutional organ which can be called upon to determine the proper allocation of powers between the several departments and among the integral or constituent units thereof.
