Appeal Resource Technical Treasury Body 2026: what approved candidates must do

Key data

The approved list of the third exercise of the Technical Treasury Body civil service exams is under judicial scrutiny. Don Alejandro Cuenda Méndez has filed the administrative contentious appeal 87/2026 against the AEAT resolution that dismissed his prior appeal regarding the publication of that list. The Human Resources Department of the AEAT has published in the BOE, dated July 10, 2026, a summons to all interested parties to appear before the Central Court of First Instance, Administrative Law Section, Position No. 8.

The deadline to act is extraordinarily brief: nine calendar days from publication in the BOE, as established by the Administrative Contentious Jurisdiction Act. Whoever fails to appear within the deadline loses the opportunity to defend their position in the judicial proceeding.

What does this regulation establish?

The resolution published on July 10, 2026 does not resolve the merits of the case, but rather fulfills a mandatory procedural function: to publicly summon all possible interested parties in administrative contentious appeal 87/2026 so they can appear before the court and defend their position.

The origin of the conflict is as follows:

• The AEAT published the approved list of the third exercise of the Technical Treasury Body civil service exams, called in December 2024.
• Don Alejandro Cuenda Méndez filed a prior appeal with the AEAT itself challenging that publication.
• The AEAT dismissed that prior appeal.
• Faced with that dismissal, the appellant resorted to judicial proceedings by filing the administrative contentious appeal 87/2026 before the Central Court of First Instance, Administrative Law Section, Position No. 8.
• The AEAT, as the defendant party, is required by law to publish this summons in the BOE so that any person with legitimate interest can appear in the proceeding.

The proceeding is governed by the Administrative Contentious Jurisdiction Act, which sets nine days as the deadline for interested parties to appear once the summons is published in the official bulletin.

Economic and operational impact

Although this appeal does not have a direct economic impact on private companies, it does have very concrete consequences for the affected candidates and for the selection process itself:

• Risk of nullity of the approved list: If the Central Court of First Instance upholds the appeal, it could annul the approved list of the third exercise in whole or in part, affecting all candidates who passed that phase.
• Paralysis or delay of the selection process: A favorable judicial resolution could require repeating the exercise or modifying the list, delaying appointments and incorporation into the body.
• Cost of legal representation: Candidates who wish to appear in the proceeding must have a lawyer and a court representative, which implies a direct economic cost that varies depending on the professional hired.
• Loss of procedural rights: Whoever fails to appear within the nine days established cannot allege anything in the proceeding or appeal the judgment rendered.

Who does it affect?

• Candidates who passed the third exercise of the Technical Treasury Body civil service exams (December 2024 call) and appear on the challenged list.
• Candidates who did not pass the third exercise and may have legitimate interest in the modification of the list (for example, if they believe the list contains irregularities that harm them).
• Candidates in general who participated in the December 2024 call and whose position in the selection process may be affected by the outcome of the appeal.
• Legal advisors and management firms that provide services to candidates or groups of civil servants in the selection process.

Practical example

Imagine you are one of the candidates who passed the third exercise of the Technical Treasury Body civil service exams in the December 2024 call and already appear on the approved list published by the AEAT.

On July 10, 2026, the summons for appeal 87/2026 is published in the BOE. From that day, you have nine calendar days to appear before the Central Court of First Instance, Administrative Law Section, Position No. 8, and defend your position as an interested party in keeping the approved list valid.

If you do not act within that deadline, the court will process the proceeding without you. If the final judgment upheld Don Alejandro Cuenda Méndez's appeal and annulled the list, you would not have been able to allege anything in your defense or appeal that resolution. The practical consequence would be the loss of your position or the obligation to repeat the challenged exercise.

The immediate action is to contact a lawyer specialized in administrative law and civil service exams to assess whether you should appear and how to do so within the nine-day deadline.

What should interested parties do now?

1. Verify if you are on the approved list of the third exercise of the December 2024 call for the Technical Treasury Body. If so, you are potentially interested in proceeding 87/2026.
2. Calculate the nine-day deadline from July 10, 2026 (date of publication in the BOE). The deadline expires approximately on July 19, 2026. Do not wait until the last day.
3. Contact immediately with a lawyer specialized in administrative law and selection processes to assess the advisability of appearing and the available arguments.
4. Prepare the supporting documentation of your status as an interested party: proof of participation in the call, certification of having passed the third exercise and any official communication from the AEAT.
5. File the appearance brief before the Central Court of First Instance, Administrative Law Section, Position No. 8, within the legal deadline, through a lawyer and court representative.
6. Monitor the proceeding once you have appeared, to be able to act in each procedural phase and, if necessary, appeal the judgment if it were unfavorable.
