This comment synthesizes the jurisprudence on a novel aspect of the Chilean criminal process, which recognizes the right to a prompt and expeditiously criminal trial for deputies and senators who have lost their parliamentarian immunity. The main reason for this immunity is to protect democratic representation that could be harmed or modified by the action of the Public Prosecutor’s Office. For this reason, when the parliamentarian immunity is removed, the deputy or senator is suspended of his parliamentary position, and the criminal process system recognizes him the right to expeditiously criminal trial.Este comentario sintetiza la doctrina jurisprudencial sobre un aspecto novedoso del proceso penal chileno, que reconoce a los parlamentarios que hayan perdido su fuero, el derecho al juicio penal de manera pronta y expedita. Lo anterior se explica como un privilegio para proteger la representatividad democrática, que puede ser modificada por la actuación del Ministerio Público. Como la declaración de desafuero produce la suspensión del parlamentario, el sistema procesal penal reconoce a ese imputado, de una manera expedita y sin posibilidad de dilaciones, el derecho al juicio.
