During the criminal investigation, the plea that a legislative provision infringes the rights and freedoms guaranteed by the Constitution is presented, in support of an application, in a separate written document stating the reasons, which is lodged at the registry of the investigating chamber and which is stamped by the registrar indicating the day on which it was lodged.
This document may also be filed with the registry of the investigating judge, the liberty and custody judge or the juvenile court judge. The court clerk then sends it to the investigating chamber without delay.
