Luis Alberto Heber's resignation from the Senate: schedule and replacements
Luis Alberto Heber's resignation from the Senate will be discussed at the session on Tuesday, October 14. The National Party legislator communicated his decision to the Herrerismo Executive Committee, a sector he will continue to chair, according to party sources. The party has already initiated formal steps to arrange his succession.
The National Party announced that Rodrigo Blás will fill the seat in the upper house. Meanwhile , in the Chamber of Deputies , Federico Casaretto will assume the seat vacated by Blás. Thus, the lineup of replacements is defined and subject to the regulatory communications of each body.
Heber has a 40-year uninterrupted career in Parliament . He was first elected at the age of 26, just shy of the constitutional requirement to serve in the Chamber of Deputies. However , his activities will not be limited to the legislative sphere: he will continue to serve on the National Party's Board of Directors and maintain the presidency of the Herrerismo .
Luis Alberto Heber's resignation from the Senate will be voted on in the chamber through ordinary proceedings.
The communication to Herrerismo included the transition plan: Rodrigo Blás into the Senate and Federico Casaretto from the House of Representatives. In addition coordination with administrative authorities from both chambers is planned to formalize oaths and appointments. In terms of day-to-day operations, the PN seeks to preserve the work without altering the already voted-on agenda.
The internal process is articulated according to the regulatory steps of the upper house. In any case , the timeline will be finalized once the resignation is voted on in the chamber. Blás's appointment follows the order of the list and the current replacement rules.

Luis Alberto Heber's resignation from the Senate: schedule, replacements, and committees
Heber served as Minister of the Interior and head of the Ministry of Transport and Public Works in previous terms. Furthermore , his continued presence on the Board implies continuity in party leadership while the handover . The PN indicated that the transition will be coordinated with the chamber's secretariat and the corresponding caucus.
On an operational level, the reshuffling of seats does not change committees until the nominations are updated. It will then be determined whether Blás will be included in the same areas or whether the representation will be adjusted. Furthermore , Casaretto must register his appointment in the lower house with the usual administrative procedures.
Luis Alberto Heber's resignation from the Senate is expected to be formalized with the presentation of the note to the floor, its consideration on the agenda, and subsequent administrative communication to the relevant bodies. The chamber will then proceed to call the substitute, who will be sworn in and assume the seat. This procedure will allow for the integration of the Senate without any interruptions in legislative work.
resignation from the Senate will trigger adjustments to committees and the caucus' agenda.
With Rodrigo Blás's entry into the Senate, the chamber's secretariat will update internal registers, access cards, and seat assignments. In parallel, the Chamber of Deputies will allow the incorporation of Federico Casaretto, as scheduled. These are routine steps aimed at ensuring the caucus's work continues.
Regarding committees, the redistribution will be adjusted according to the representation of each sector. First, the availability of the new senator is verified and, if appropriate, his or her inclusion in already open areas is proposed. In any case, until the plenary session confirms these movements, the committees will continue with their current composition and already established agenda.
resignation from the Senate does not alter the leader's position on the National Party's Board of Directors or his presidency of the Herrerismo. At the party level, this allows for continuity in leadership while Parliament completes the transition of seats.
For the week of the session, the coordinators prepare the voting schedule, any tributes, and the announcement of the replacement. They also organize communications with the press and update institutional websites. It's an administrative process, but a sensitive one for those who follow daily politics.
Operationally, the change does not alter the schedule of projects already submitted. If a technical report was the responsibility of the outgoing senator, the caucus will relocate that work to a new rapporteur. The priority is to ensure that deadlines are not held up : budgets for entities, appointments, and international agreements continue their course.
Finally, Luis Alberto Heber's resignation from the Senate closes four consecutive decades in Parliament and opens a new era with new appointments in both chambers. For the public, the goal is simple: to ensure that the change in the quality of legislative service is as minimal as possible.
