This research aims to investigate the hermeneutic-analytical dialogue between the area of co-operators in the communicational production of Law. Just as these communication processes do not see a single beneficiary, neither do they see a single author. For example, legislative texts, or the texts of court judgments are the result of discussion (parliamentary debate; judicial debate) in which various creators and co-operators of texts are involved who will then contribute to the drafting of the final legal text (parliamentary commissions, legal advisors; legal experts; other professionals also not directly jurists who intervene in the judgments as advisors). Semiotic and communicational relations are innumerable in the contemporary world of law. Intergovernmental agencies, supervisory authorities, and various legal decision-makers collaborate with the classical “legal authorities” from the conventional power distribution model for law (legislative, executive, judicial). But the levels are now much more varied and increased (administrative, national, supranational). The current legal landscape envisages a semiotic and communicational dialogue between the world of the various authors of legal texts with the legal authorities of the final decision-makers in the communicational processes of law, and thus legal authorities in the communicational sense as final and definitive emissaries of legal texts. These aspects will be approached through the semiotic levels of analysis of Gregorio Robles’ Communicational Theory of Law: formal level (syntactic), level of legal method (semantic) and above all level of decision-making in law (pragmatic). The Communicational Theory of Law makes it possible to see the dialogue between “authoring” and “legal authority” through the analyses of the communicational relations it proposes between text, co-text, and the context of the ambits of law.
