Parties to the main proceedings

Applicant: Caronte & Tourist SpA

Defendant: Autorità Garante della Concorrenza e del Mercato

Question referred

Must Article 102 TFEU, read in the light of the principles of protection of competition and effectiveness of administrative action, be interpreted as meaning that it precludes national legislation, such as that arising from the application of Article 14 of legge 24 novembre 1981, n. 689 (Law No 689 of 24 November 1981) — as interpreted in the most recent case-law — which requires the Autorità Garante della Concorrenza e del Mercato (National Competition Authority, Italy) to initiate the investigation procedure with a view to establishing an abuse of a dominant position within a time limit of 90 days, starting from the moment the Authority has knowledge of the essential elements of the infringement, the latter of which may be met by the first report of the infringement?
