The impacts of constitutional disputes  on the position of President in Mexico

The Constitution of 1917 expressis verbis expressed the constitutional principles of the division of powers in Mexico. In practice, the executive branch had a dominant role. In the eighties, there was a slow economic and political transformation that shaped the formation of the democratic system of the state. The independent judiciary, in particular the position of the Supreme Court of Mexico (SCJN), began to play a special role. An important systemic practice after the 1994 reform was the settlement of constitutional disputes (controversias constitucionales) of executive organs with legislative bodies at both federal and state levels. SCJN became an arbitrator deciding on collisions. A question arises about the scope of influence of constitutional disputes on the political position of the President from the mid-nineties? Based on the analysis of the content of normative acts and taking into account their historical background, one can conclude that – despite the transformation – presidential power still exerts a significant influence on the judiciary in Mexico.
