The Supreme Court of Justice’s Sala de Instrucción is evaluating a potential nullification of the indagatoria—a preliminary judicial inquiry—conducted by Magistrate Cristina Lombana against Senator Martha Peralta. The senator, a member of the Pacto Histórico, is under investigation regarding the corruption scandal at the National Unit for Disaster Risk Management (UNGRD). During a session on July 16, the five attending magistrates deferred a final decision on the senator’s legal status, following a previous postponement requested on July 9 by Magistrate César Reyes to review the full case file.
Legal Challenges and Potential Procedural Shifts
The core of the current judicial debate involves a memorial filed by the senator’s new defense attorney, Marlon Díaz. According to reports, the document was circulated among a broad segment of the Court despite being intended for the Sala de Instrucción. The filing requests that the Court refrain from ordering imprisonment as it defines the senator’s legal situation. This move has prompted the Sala de Instrucción to consider whether to incorporate the defense’s arguments and potentially revert the case to an earlier procedural stage.
Sources indicate that the Court is assessing claims of a potential nullity based on the alleged illegality of the preventive detention previously imposed on Senator Peralta to facilitate her inquiry. While a Bogotá family judge, Sandra Isabel Bernal, previously rejected a habeas corpus petition filed by the senator, confirming the validity of the Supreme Court’s initial measure, the current discussions could lead to a change in venue. If the inquiry is declared null, the case could move from Magistrate Cristina Lombana’s office to that of Magistrate César Reyes, following alphabetical order protocols. This transition has occurred previously in cases involving Armando Benedetti, who has faced multiple investigations in the Court.
Did You Know?
Senator Martha Peralta was previously held in preventive detention for five days in connection with the UNGRD case before the Supreme Court lifted the measure and moved to define her legal status.
Defense Strategy and Professional Connections
The appointment of Marlon Díaz as defense counsel has drawn attention due to his professional relationship with David Benavides, the attorney representing Armando Benedetti. Benavides confirmed he is friends with Díaz and noted that he provided advice to the senator’s legislative unit (UTL) team regarding procedural questions, such as the viability of filing a habeas corpus or a tutela. However, Benavides denied any coordinated strategy to influence the Court or remove specific magistrates from the proceedings.
Marlon Díaz acknowledged filing the memorial but declined to discuss its contents due to legal privilege. He emphasized that he manages his legal defense strategies independently and maintains a professional, academic history as a colleague of Benavides. Regarding the potential nullification of the inquiry, Díaz stated that any judge or court may officially declare a nullity if they identify grounds for one, though he noted he does not know if that outcome is currently being considered by the Sala de Instrucción.
