En el documento se analizaron los aspectos generales del camino recorrido por la Corte Constitucional para dar a algunos de sus fallos, rango de Ley. Se parte de una breve descripcion del caso del derecho anglosajon Marbury vs. Madison, para luego cotejar la interpretacion que sobre el termino ‘leyes’ tiene la Corte Interamericana de Derechos Humanos, con la aprehendida por la Corte Constitucional colombiana. A traves del analisis documental de distintas normas y sentencias se detallaron los argumentos dados por la Corte Constitucional para justificar un cambio de valor de su jurisprudencia.
