The purpose of the article is to analyse the linguistic regime established in Catalonia by the new Catalan Statute of Autonomy (new Catalan Statute). After preliminary reflection on the role of the regulation of this regime under the new Catalan Statute, the article discusses the debates on the subject that arose during the drafting process of the later, before examining four specific regulations in it. First, it refers to the obligation to have a knowledge of Catalan and the nature of such an obligation; second, to the consolidation of the legal position regarding the Aranés language ; and—following this—the article analyses the types of participation undertaken by the Spanish central government and the Generalitat (the Catalan Government) in the foreign projection of the Catalan language at European and international levels, and in the relationship held with territories having linguistic associations with Catalonia. Fourth and finally, it assesses recognition of a catalogue of linguistic rights in different public and private sectors (Public Administration and particularly the area of justice, and business) companies). In this sense, therefore, the article carries out a complete analysis of the new Statute’s contributions to the linguistic regime.
