The used methodology will be bibliographical, with historical and comparative analysis and use of analytical models. The treatment will be initially scientific, with proposals in the conclusion, being the sources of research basically doctrinal, with the study of the referring constitutional rules to the subject passing through the work, and discussing selected decisions of the STF to the end.
