How to draft an appeal against administrative silence with AI
4 min read · Updated June 2026 · Editorial oversight: Avv. Federico Papa
The appeal against administrative silence-omission (silenzio-inadempimento) is the procedural tool aimed at obtaining a declaration of the obligation to act and an order to conclude the proceedings. Governed by Art. 117 c.p.a. in conjunction with Art. 31 c.p.a., this expedited summary proceeding is triggered when the administration fails to issue a final decision within the time limits set by Art. 2 of Law 241/1990. The action can be brought as long as the failure to act persists and, in any case, no later than one year from the expiry of the deadline for concluding the procedure. It aims to protect the private party's legitimate interest in the temporal certainty of administrative action, ensuring an explicit response, whether favorable or unfavorable.
In brief
The appeal against silence-omission, under Articles 31 and 117 c.p.a., protects the legitimate interest in concluding administrative proceedings within Law 241/1990 deadlines. The action is admissible for one year following deadline expiry, excluding significant silence. This expedited procedure requires filing via PAT within 15 days of service to the administration and interested parties. The court declares the obligation to act and may assess claim merits during non-discretionary activity, appointing a commissario ad acta. Drafting via AI involves documenting the administration's inertia and the petitioner's concrete interest in the ruling.
The steps
- 1.
Verification of requirements and deadlines
Before taking legal action, it is necessary to verify that the deadline for concluding the administrative proceeding, established by Art. 2 of Law 241/1990, has actually expired without an express measure being adopted. The appeal can be filed as long as the failure to act persists, but strictly within the limitation period of one year from the expiry of the deadline for concluding the procedure. It is essential to ascertain the nature of the original application, as the procedure under Art. 117 c.p.a. does not apply if silence is legally equivalent to consent or refusal (silenzio significativo).
- 2.
Identification of jurisdiction and parties
The appeal must be addressed to the Regional Administrative Court (T.A.R.) in whose district the defaulting administration is based or where the effects of the omitted act would occur. It is necessary to correctly identify the respondent administration and any interested third parties (controinteressati), namely subjects who benefit from the failure to adopt the measure. Failure to serve notice on at least one interested third party, if any, results in the inadmissibility of the appeal according to the general rules of administrative procedure.
- 3.
Statement of facts and duty to act
The pleading must accurately describe the application submitted by the private party and the regulatory framework that requires the Public Administration to conclude the proceedings with an express measure. Evidence of receipt of the application must be attached, and the administration's inertia beyond the legal deadlines must be documented. A prior letter of formal notice (diffida ad adempiere) is no longer required, but it is fundamental to demonstrate the existence of a current and concrete interest in the judicial ruling.
- 4.
Formulation of grounds and merits
In addition to seeking a declaration of the illegality of the silence, the petitioner may ask the court to rule on the merits of the claim, pursuant to Art. 31, paragraph 3, c.p.a. This request is admissible only if the activity is non-discretionary (attività vincolata) or if no discretionary power remains with the administration. In such a case, the appeal must contain technical arguments intended to demonstrate that the Public Administration would have no choice other than to grant the original application.
- 5.
Service and filing of the appeal
The appeal, after being served on the administration and at least one interested third party, must be filed with the registry of the competent T.A.R. within 15 days of the last service. Since this is a special expedited procedure, procedural deadlines are halved, except for those relating to the filing of the action. The filing must take place electronically via the Processo Amministrativo Telematico (PAT), attaching the original application and proof of service.

Mistakes to avoid
- Filing the appeal against tacit rejection (silenzio-rigetto) or tacit consent (silenzio-assenso), which must instead be challenged via ordinary proceedings against the tacit decision.
- Exceeding the one-year deadline from the expiry of the administrative proceedings, resulting in the forfeiture of the action under Art. 31 c.p.a.
- Failing to serve notice on at least one interested third party, rendering the appeal inadmissible for failure to establish proper joinder of parties.
- Requesting an assessment of the merits of the claim when the Public Administration still holds broad unexercised discretionary powers.
Frequently asked questions
Is a formal notice (diffida) necessary before filing the appeal?
No, Art. 117 c.p.a. no longer requires a prior formal notice (diffida), as the mere expiry of the deadline under Art. 2 Law 241/1990 is sufficient.
What is the deadline for filing the appeal after service?
The appeal must be filed within the shortened deadline of 15 days from the last service, as it is a special expedited procedure.
What happens if the P.A. issues a measure after the appeal is served?
If the subsequent measure is favorable, the court declares the termination of the matter in dispute; if it is unfavorable, the petitioner may challenge it by filing amended grounds (motivi aggiunti).
