Este escrito cuestiona la validez y autenticidad de un consenso constitucional democratico como fundamento de la Carta de 1991 y propone, en su lugar, la hipotesis del consenso constitucional factico, como resultado de la profunda crisis de legitimidad del sistema politico colombiano, agudizada por la accion del narcoterrorismo de los “extraditables” al mando de Pablo Escobar, y por la incorporacion de nuevas fuerzas politicas y sociales a la institucionalidad, comprometidas con la construccion de un nuevo orden politico democratico, cuyas senales de identidad son el Estado Social de Derecho y la democracia participativa. This article questions the validity and authenticity of a democratic constitutional consensus as a fundamental element of the 1991 Constitution, and proposes, in its place, the hypothesis of a factual constitutional consensus, as a result of the profound crisis of the legitimacy of the Colombian political system, aggravated by the actions of the «narcoterrorists», the «extraditables», under the control of Pablo Escobar, and for the incorporation of new political and social forces in the institutional structure, who are committed to the building of a new democratic political order, and who are identified with the Welfare State and participative democracy.
