Ventured into the study of Roman nullitatis complaint, which during the course of time it was molding over the centuries on either legislation until today, all with the aim of achieving effective review of the res judicata. In this, the work of the Constitutional Court Praetorian Bolivia had a extensive work, which, there is a permissive thesis Autonomous Action of Nullity irritated by res judicata and its turn, defines that the jurisdiction of the High Court --- really --- only it is for concise and precise violations of constitutional roots, but not a third instance to which the law enforcement agents at the request usually go through the constitutional amparo action called. I end by making the findings of the case study as a starting point for future research to be done by the reader.
