If democracy is common sense and rolling means rule by the people for himself, which means direct democracy as the practical impossibility of this has necessitated that the people choose representatives to the exercise of power rather than a curse which is known as the parliamentary system. If the parliamentary system and one of the most parliamentary systems as well as the presidential system and the local system had been marked by the characteristics and mechanisms essential to distinguish them from other systems is bound to confuse the characteristics and mechanisms of belonging to a particular system with the characteristics and other mechanisms that lead to corruption of the result to be achieved and thus may lead for the demolition of the democratic system as a whole.And that of the basic principles of the parliamentary system is the availability of _khasastin basic first - dual executive power, and the second - a chapter flex between the authorities and the existing relations of cooperation balanced and reciprocal control between them at that Coleman these Al_khasastin conditions and requirements of objectivity, which should be available to the system is a parliamentary achieved the desired goal of it.There is no doubt that the parliamentary system (parliamentary) was not novel for the first time under the Constitution of the Republic of Iraq in 2005 in force, it is a constitutional institution old have been developed since the Ottoman occupation of Iraq (1534-1914) and then continued under the occupation of England, and also in light of the Republic of the current sixth But this time there was a data probably were not present in previous systems.If the parliamentary experience that followed the issuance of the Basic Law of 1925 has resulted in the occupation of England, the current experience in light of the 2005 Constitution in force has also generated under U.S. occupation, which made a number of researchers and specialists record a lot of observations and criticisms on these two experiences. Comes from here the importance of research and motivation to put both experiments in the balance of criticism aimed for the purpose of diagnosis and treatment aspects of slippage in furtherance of the spirit of democracy that we aspire together to achieve and it was divided this research the three main chapters, devoted the first to demonstrate the nature of the parliamentary system, came second to study the elements of the parliamentary system under Constitution of 1925, while the third has Chrisnah to study the parliamentary system under the 2005 Constitution in force.
