Resumen Este artículo abarca la configuración conceptual del derecho de postulación en Colombia, detallando la amplitud de sus excepciones, donde legal y constitucionalmente se autoriza la intervención directa. Luego de explicar acciones, hipótesis y controversias motivo de excepción; se muestra el esquema de las modalidades del poder en el Código General del Proceso y las vicisitudes de la presentación personal ¡unto con propuestas al respecto; sin olvidar de otro lado, la normatividad para conferir los poderes bajo la emergencia económica, social y ecológica de la pandemia COVID-19. De esta forma, después de emprender un recorrido analítico, se precisa el alcance teórico y la operatividad dé los fenómenos de la revocatoria y renuncia del poder, como motivos para la finalización del mismo, a los cuales se agregan, dentro de esta investigación, la muerte del apoderado y dos clases de inhabilidades bautizadas como 'inhabilidad sobrevenida e 'inhabilidad originaria', las cuales no constituyen causal de nulidad procesal.

Abstract This article covers the theoretical concept of the right to nomination in Colombia detailing its many exceptions where direct intervention is authorized both legally and constitutionally. After having explained the legal actions, various hypothesis, and controversies that, in turn, constitute exceptions, the General Code of Procedures framework and the many vicissitudes of the physical appearance, along with proposals in such regard, are shown without forgetting, on the other hand, the statutes by which powers of attorney are to be produced during the current time (COVID-19). In this sense, after an adequate analysis, the theoretical reach, as well as the mechanism of action of the revocation of the power of attorney and its renunciation (causes for termination) are laid out. Among the latter, the death of the law7er representing his or her client and two kinds of legal incompetence known as: «sudden incompetence» (fortuitous) and «original incompetence» (by nature), which do not constitute cause for procedural nullity. Hie methodology by which this article was written had the very intention of analyzing the statutes set forth before and after the 1991 Constitution, and before and after the doctrine (jurists) and case law; statutes in which comments, critics, and propositions are observed due to the existing "symbiosis" between Procedural Law and Positive Law.
