The principle of separation of powers in Russian Federation was fixed the Russian Constitution of 1993. It is a model for the governance of a state, when the state is divided into branches, each with separate and independent powers and areas of responsibility so that the powers of one branch are not in conflict with the powers associated with the other branches.
In Russia there is the typical division of branches is into a legislature, an executive, and a judiciary. In theory, these departments should be separate and distinct because of the corrupting nature of power. To prevent one branch from becoming supreme, government systems need a way to balance each of the branches. Typically this was accomplished through a system of "checks and balances". But there are some special characteristics of this principle. The Russian Constitution allows the president an even more dominant role in the political system, giving him the right to issue decrees.
The new Russian Constitution introduced presidential supremacy and placed the Executive above the other branches of government. Moreover, there are some problems when the State Duma expresses disbelief to the Government or when the President don’t want to approve this or that law. So the latest chances in Constitution have showed that the role of President continue to increase. Thus the principle of separation of powers in Russian Federation and the system of "checks and balances"aren’t fully realized in the Russian Federation.
