Abstract
The principle of separation of powers is the main and basic principle upon which all parliamentary systems stand, and each system has its own interpretation of this principle, including the parliamentary system, which embraced the separation of powers as a chapter marred by the spirit of cooperation and mutual oversight between the legislative and executive authorities, and which made this cooperation and oversight a fundamental pillar on which it rests and confirms. Its existence, which led some jurists to say that cooperation and oversight is the basis for the existence of the parliamentary system, and rather to say that this cooperation does not exist in other parliamentary systems, namely the presidential system, which is based on the absolute separation of powers, and the council system, which is based on the dominance of power Legislative authority over the executive authority, there is no room for cooperation in these systems, but the parliamentary system is unique to them and is exclusive to them
