The aim of the research is to examine and analyze the weaknesses of regulations on the Advocate Organization System that is not yet Single-bar, and how to reconstruct the regulations based on the value of pancasila justice. This research was conducted using socio-juridical research which is a legal research method that functions to see the law in its real sense and examines how the law works in a society that is analytically descriptive using primary and secondary data and using the theory of pancasila justice as a grand theory. The Weaknesses of the Advocate Organization as State Organs is that the Advocates organization in the form of an Advocate Organization after the enactment of Law Number 18 of 2003 concerning Advocates is not a state organ (state organs) in the real sense which has a degree of constitutional importance that is equivalent to other law enforcement institutions but only as association organs that are supporting (state auxiliary institutions). Therefore, Law Number 18 of 2003 concerning Advocates needs to be reconstructed in its value including placing an Advocate Organization as a Single Bar, and not in the form of an Association, then forming the Indonesian Advocates Commission as an external Supervisor, that is equivalent to law enforcers but not as enforcers of laws that give rise to gradations of law enforcement but rather that Advocate Education must be in the form of a Special Law Degree in the Advocate Profession therefore, the form of the substantial reconstruction is in the Norms of Article 2 paragraph (1), Article 3 paragraph (1), Article 5 paragraph (1), Article 12 paragraph (1) Chapter 28 paragraph (2) of Law Number 18 of 2003 concerning Advocates.
