The creation of the National Anticorruption System is a fundamental public policy decision, historic and unprecedented, to combat corruption. A negative phenomenon that has taken root in our country and has become one of the main obstacles to its economic and social development. The decision to create the System was the result of the will of the main political actors in the country, represented in the Chambers of the Congress of the Union and in the Federal Executive, as well as in the Legislatures of the Federal States, who participated not only in the approval and promulgation of the constitutional reform but also in the formulation of initiatives and proposals to create, from the Federal Constitution, the conditions and legal figures, instruments, institutions and competencies, with their due articulation. Aspects related to the legislation that regulates the National Anticorruption System are analyzed. This system establishes the mechanisms through which the authorities linked to the control of public resources of the three levels of government will coordinate and collaborate.
