This paper examines the function of the Permanente Review Tribunal “TPR” as a possible actor for the consolidation of democratic governance and the democratic state. In this sense, the question that will be the axis of analysis of this work is posed in the following terms: Does the TPR have any function aimed at guaranteeing democratic governance and the democratic state in the States that make up this integration process? As can be seen, this study is based on a systemic vision where the Supreme Court of Mercosur could be in a feedback relationship with the internal legal systems of the States parties that comprise it. The Work is organized as follows: (i) firstly, some guidelines are made on the central notions used in this work (democratic governance, rule of law and democratic state) (ii) secondly, we will make a general exposition on the essential elements that make up the so-called broad democratic dimension and the Ushuaia Protocol (PU) on democratic commitment in MERCOSUR, (iii) Next we will address the question of the role of jurisdiction in the integration processes in general and in MERCOSUR , in particular, focusing attention on the work carried out by the TPR, (iv) finally, an Award issued by the TPR will be brought to consideration that may leave some clues to answer the question posed. The method used in this research is essentially analytical.
