VII. Senator Fleur De Lis is charged with plunder before the Sandiganbayan. After finding the existence of probable cause, the court issues a warrant for the Senator's arrest. The prosecution files a motion to suspend the Senator relying on Section 5 of the Plunder Law. According to the prosecution, the suspension should last until the termination of the case. Senator Lis vigorously opposes the motion contending that only the Senate can discipline its members; and that to allow his suspension by the Court would violate the principle of separation of powers. Is Senator Lis's contention tenable? Explain. (4%)
