The rights and constitutional guarantees to be respected in the process, is one expression of the right to freedom, hence acquire a range of fundamental rights and guarantees. I mention these constitutional principles, throughout my research work, are not simple maxims, new sayings, thoughts and aphorisms, but they are rules of constitutional order necessarily be observed. In this paper, I try to make succinctly analysis of specific and common principles of Civil Procedure and Criminal Procedure and the procedure and the principles of justice, because for that the application of fundamental principles enshrined in the Constitution must be immediately applicable rule in the Civil and Criminal Procedural Law by the administrators of justice. The application of the principles and constitutional norms should be observed both in procedural law, as in this case, at present there is a wide range of classifications of the principles of procedural law which differ in the location and designation criteria but all of them must always be framed under constitutional protection. There are procedural law principles that have some common elements and other processes, which form a system of knowledge that allowed by the structural trilogy of procedural law, support the unitary conception of it in our country, for its proper application, in close agreement with the constitutional provision.
