The RECOPE LRB itself marked a milestone in the history of the LRBs in the Costa Rican public sector (institutional and corporate), basically on the basis of the binding nature of its agreements, as provided for in its constitutive legal regime. After a jurisdictional intervention by the Constitutional Chamber of the Supreme Court of Justice, which annulled the precept of such binding nature for the employers' enterprise, the fate of the collegiate agreements of the JRL within RECOPE would be left to determinants - causes or factors - no longer so much legal (the entity, content and quality of the other organic, programmatic and procedural rules of its particular regime) as extra-legal (more circumstantial and even personalistic, political, ideological, inter-institutional and so on). Questions then arise as to what these determinants are, the relative importance of legal versus non-legal ones, and how the 'adverse' effects of one or the other could be mitigated in order to enhance the effectiveness of the interventions of the LRB towards the realisation of its foundational purposes.
