Abstract
The paper analyzes how in the current adversarial criminal system the dogma of the accusatory principle lacks an applicable structure; it shows how, strangely enough, this postulate is used despite the fact that it is conceived in the face of institutions that, precisely, were part of the repealed inquisitorial system. Thus, the aim is to show how such nuances ended up distorting a design that promised to solve the most important problems of criminal procedural law and failed to do so.
