EnglishLaw has two dimensions: on the one hand, it can be linked to the maintenance of an unjust status quo; but, on the other hand, it can also be an instrument of fight for any social actor. This idea will be developed throughout the analysis of the right to self-determination, object to the present article.Self-determination is a rather old concept understood as self-governance before the states. At the beginning of the twentieth century, social actors recognized this concept as a right, and subsequently as a human right. This article will focus on the notion of self-determination from a theoretical point of view, while also mentioning some historical elements that will complement the historical relevance this right has had. Hence, I will first start by explaining what self-determination meant from John Locke s standpoint, which is linked to natural law-liberalism. Likewise, I will consider the Marx-Leninists perspective that supported the African decolonization. Finally, I will illustrate how global indigenous movements reinterpreted the notion of self-determination and materialised it through the Bolivian Constitution. With this, the reader will see how law and human rights are both indeterminate and difficult-to-reconcile concepts. EnglishEl derecho tiene dos dimensiones: puede representar un statu quo injusto, pero asimismo puede representar una herramienta de lucha aplicable a cualquier actor social. Esta idea es desarrollada en este articulo a traves del analisis del derecho a la autodeterminacion.La autodeterminacion es un viejo concepto que representa el autogobierno ante los Estados. Sin embargo, recien a principios del siglo XX se reconocio como derecho y, posteriormente, como derecho humano. En este articulo, se analiza la nocion de autodeterminacion desde un alcance teorico sin dejar de lado algunos elementos historicos. Primero, el articulo explica lo que significo la autodeterminacion desde el punto de vista de John Locke como representante de la ley natural: el liberalismo. Posteriormente, se analiza desde la perspectiva de Marx y Lenin, quienes se cons-tituyeron en un fundamento a favor de la descolonizacion africana. Finalmente, se resalta como los movimientos indigenas globales reinterpretaron la nocion de autodeterminacion a traves de la Constitucion boliviana y el concepto de Sumak Kawsay. Este caso ejemplifica como el derecho y los derechos humanos pueden ser un territorio indeterminado y disputable
