In the best literature on unilateral secession, for instance, Buchanan, it is usual to distinguish between remedial theories, which require a just cause for conceding a right to secession for the inhabitants of a territory, part of a State; and primary theories, plebiscitary theories and adscriptivist or nationalist theories. In accordance to this view, only the first are capable of justifying a unilateral right to secession. Well then, in this paper, an argument is elaborated in order to show that the (...) remedial strategy is not applicable to Catalonia and, also to show that even if primary theories are applicable to the case of Catalonia —the plebiscitary strategy has given rise to the so-called right to decide—, they are not able to justify a unilateral right to secession.
