对行政、立法机构或特别法庭的官员进行刑事起诉要求有一个预审程序，以此 剥夺有关官员的特权和豁免权（或者，在司法机关成员或检察署官员所涉案件 中，要求有一个初步程序，以确定该人员是否是在履行其职责时实施了犯罪）。 自从智利新的刑事诉讼制度生效以来，已请求对议员进行了 4 次此类程序，从 而使得在每一个案件中启动调查成为可能。
The criminal prosecution of officials of the executive, the legislature or the special courts requires a pretrial proceeding whereby the official in question is stripped of his or her privileges and immunities (or, in the case of a member of the judiciary or an official of the Public Prosecution Service, a preliminary proceeding to ascertain whether or not that person has committed an offence in the discharge of his or her duties). Since the entry into force of the new system of criminal procedure in Chile, four such proceedings have been requested in respect of members of Parliament, as a result of which the initiation of investigations in each case has been made possible.
