Internacionalización del Derecho Constitucional y Judicialización de la política: el impacto del Sistema Interamericano de Protección de Derechos Humanos en la resolución de controversias socio-políticas en Costa Rica.

The importance of the Constitutional Chamber of the Supreme Court of Costa Rica in the resolution of the main controversies that affect the country, from the presidential re-election to the debate on equal marriage, reveals a tendency towards the judicialization of politics. This phenomenon has taken on a new dimension by integrating a new actor into the system: the Inter-American Court of Human Rights. If, until a few years ago, the constitutional judge was considered the ultimate referee of political and constitutional conflicts, the internationalization of constitutional law has meant that more and more disputes are decided on the inter-American scale. This article will look through three examples – the case of IVF, therapeutic abortion and equal marriage – in order to analyze this phenomenon and its impact on the Costa Rican constitutional model.
