How to file an AGCM antitrust complaint with AI
4 min read · Updated June 2026 · Editorial oversight: Avv. Federico Papa
A complaint to the Italian Competition Authority (AGCM) constitutes the key initiating act to prompt the Authority's investigative powers regarding market-distorting conduct. Pursuant to Article 12 of Law No. 287/1990, any interested party may report facts constituting competition infringements under both national and EU law. The complaint aims to highlight restrictive agreements or abuses of a dominant position that harm consumer welfare and market efficiency. Rigorous and precise drafting is essential for the Authority to establish a sufficient basis to initiate formal investigative proceedings.
In brief
A complaint to the Italian Competition Authority (AGCM) triggers investigative powers regarding restrictive agreements or abuse of a dominant position. Pursuant to Law 287/1990, the filing requires the identification of parties and definition of the relevant market. Conduct must be analytically described and qualified under Articles 2 and 3 of Law 287/1990 or Articles 101 and 102 TFEU. Complainants must provide evidence and may request sanctions or interim measures under Article 14-bis. AI tools support the technical drafting to establish the basis for formal proceedings.
The steps
- 1.
Identification of the parties and legal standing
The first step requires a precise identification of the complainant and the reported undertakings, detailing their respective roles in the market. It is necessary to set out the concrete and actual interest of the complainant (whether a harmed competitor, a consumer, or a trade association) and define the economic relationship with the reported parties. Certified email (PEC) addresses and registered office addresses must be provided to enable the Authority to properly issue notifications and carry out any inspections. Soundly argued legal standing prevents the risk of dismissal for lack of interest or subjective vagueness.
- 2.
Definition of the relevant market
The complaint must contain a precise definition of the relevant product market and the geographic market in which the challenged conduct takes effect. From a product perspective, it is necessary to identify the goods or services considered interchangeable or substitutable by consumers in view of their characteristics, price, and intended use. From a geographic perspective, the area where undertakings compete in the supply and demand of such products must be delimited, assessing whether the scope is local, national, or EU-wide. This analysis is essential for calculating market shares and evaluating the economic power of the undertakings involved.
- 3.
Analytical description of the conduct
This section requires a detailed exposition of the facts and conduct alleged to be anti-competitive, such as cartel agreements, exchanges of commercially sensitive information, or exclusionary practices. It must be clarified whether the conduct constitutes a horizontal agreement aimed at price-fixing or an abuse of a dominant position intended to foreclose competitors from the market. Each practice must be contextualized chronologically, indicating its commencement, whether it is ongoing, and its operational modalities. A precise factual narrative enables the Authority to readily assess the severity of the infringement and the need for prompt intervention.
- 4.
Legal qualification of the infringement
The complaint must subsume the established facts under the relevant legal prohibitions, distinguishing between restrictive agreements pursuant to Article 2 of Law No. 287/1990 and abuses of a dominant position under Article 3 of Law No. 287/1990. Where the conduct is liable to affect trade between EU Member States, Articles 101 and 102 TFEU must also be cited. Substantive arguments must demonstrate how the conduct prevents, restricts, or appreciably distorts competition within the national market or a substantial part of it. Accurate legal qualification guides the Authority in selecting the appropriate investigative instruments and in coordinating competence with the European Commission.
- 5.
Evidentiary framework
The complainant bears the burden of producing or referencing all documentation and factual evidence available to substantiate the allegations. Relevant submissions may include contracts, commercial correspondence, price lists, sales data, or third-party statements demonstrating collusion or abusive practices. Submitting economic studies or expert opinions to quantify market impact or entry barriers is highly recommended. A robust evidentiary foundation significantly increases the likelihood that the AGCM will act upon the complaint, potentially conducting unannounced inspections (dawn raids) at the undertakings' premises.
- 6.
Formulation of requests and interim measures
The concluding section of the complaint must formally request the Authority to open an investigation to ascertain the infringement and impose appropriate sanctions. In urgent cases involving serious and irreparable risk to competition, the complainant may apply for interim measures pursuant to Article 14-bis of Law No. 287/1990. It is equally essential to submit a formal request for confidential treatment of documents containing trade secrets or sensitive business information. Precision in the relief sought assists the Authority's officers in defining the scope of the investigation.

Mistakes to avoid
- Overly broad definition of the relevant market, preventing the Authority from properly assessing the true market power of the undertakings.
- Failure to distinguish between a purely private contractual dispute and conduct carrying public antitrust relevance.
- Incomplete evidentiary or circumstantial basis, leading to immediate dismissal of the complaint for manifest groundlessness.
- Omission of a formal confidentiality request for sensitive data, resulting in disclosure of trade secrets to counterparties during access to records.
Frequently asked questions
Does filing a complaint with the AGCM involve fixed costs?
No, filing a complaint does not require payment of administrative fees or taxes, though it necessitates careful technical and legal drafting.
Is it possible to file a complaint anonymously?
Although the Authority may act ex officio, the complainant must state their identity; however, non-disclosure of identity may be requested if there is a well-founded fear of commercial retaliation.
What are the average timeframes for initiating an investigation?
