The Divergent Jurisprudential Paths of the Andean Tribunal of Justice and the European Court of Justice
This chapter explains how the Andean Tribunal of Justice (ATJ) has significantly diverged from several foundational integration law doctrines developed by the European Union's Court of Justice (ECJ). As such, this updated analysis discusses how the ATJ refined the complemento indispensable principle to more clearly delineate the boundary between Community and national legal authority and to uphold the primacy of clear Andean rules. This principle is a doctrine that permits national laws and regulations to implement and fill gaps in Andean secondary legislation (known as Decisiones). The ATJ has also asserted the supremacy of Andean law over conflicting bilateral and multilateral treaties, and accepted preliminary references from administrative agencies and arbitral panels. In addition, the ATJ has for the first time addressed human rights, stating, albeit in dictum, that governments must prioritize the socio-economic rights of Community citizens over free trade and integration rules.
