Automated Summary
Key Facts
The case involves Abbanoa s.p.a. and PAU Giovanni regarding the annulment of a 2016 water bill for 'conguagli partite pregresse 2005/2011' and a 50% reduction in charges for periods when non-potable water was supplied. The Giudice di Pace (2020) and Tribunale di Nuoro (2022) confirmed the reduction, citing regulatory principles and statutory requirements for tariff adjustments. The higher court's decision highlights disputes over cost recovery mechanisms, tariff calculation methods, and the application of legal provisions (e.g., art. 154 d.lgs. 152/2006) to determine liability for service quality issues.

Water Service Agreement and Billing Dispute
Issues
- The fourth issue challenges the lower court's decision on non-potable water for lacking adequate motivation. The plaintiff claims the court failed to critically evaluate the municipal orders (ordinanze sindacali) that restricted water use, arguing these restrictions were not 'absolute' or severely disruptive. This raises questions under art. 111, comma 6, Cost. and art. 132, comma 2, n. 4 cod. proc. civ., regarding the necessity of detailed reasoning for factual decisions impacting the user's rights.
- The third issue addresses the application of civil code articles (1490, 1492) to cases of non-potable water. The court must assess if the lower court correctly applied the principle of price reduction for defective services, particularly whether the service of water supply (a complex, regulated service) allows such deductions. The plaintiff argues that the tariff is based on overall service costs, not the quality of the water itself, and that the 50% reduction improperly referenced a now-expired CIP provvedimento (n°26/1975).
- The first issue concerns the legality of recovering past costs (2005-2011) via tariff adjustments under the Service Integrated Water (SII) regulatory system. The court must determine if the method used by the AEEGSI (now ARERA) and regional authorities to quantify and recover these costs aligns with the principles of 'full cost recovery' (art. 9 Dir. 2000/60/CE) and relevant provisions (art. 154 d.lgs. 152/2006). The plaintiff argues that the lower court incorrectly interpreted these provisions, allowing for retroactive cost recovery.
- The second issue revolves around the calculation of the five-year statute of limitations for claims of past cost recovery. The plaintiff contends the lower court erred by using the end of each consumption period as the starting point (dies a quo), rather than the date the costs were officially approved (26.06.2014) under the new tariff regulations. This challenges the application of art. 2948, n. 4 cod. civ., and the validity of the lower court's reasoning.

La Corte ha disposto il rinvio della causa a nuovo ruolo, in attesa della pronunzia delle Sezioni Unite, per la decisione sulla problematica relativa alla spettanza al gestore del servizio idrico integrato dei conguagli regolatori e sull'applicazione delle norme in materia di prescrizione del credito, qualità dell'acqua e motivazione della sentenza.

Legal Principles
The court addressed principles related to the interpretation and application of tariff regulations for cost recovery in the water service sector, including the 'full cost recovery' principle under EU Directive 2000/60/CE (art. 9) and the determination of the statute of limitations (prescription) for billing claims. It emphasized that regulatory cost adjustments must align with statutory frameworks and that the prescriptive period for conguaglio claims begins when the tariff becomes enforceable, not retroactively. The decision also critiqued the lower court's reliance on outdated provisions (e.g., CIP 26/1975) and misapplication of civil code principles (e.g., art. 1490, 1492) in the context of regulated services.

Key Disputed Contract Clauses
- Article B.16 of the Integrated Water Service Regulation specifies that consumption determinations are subject to the tariff system set by the Regulatory Authority, which is central to the court's analysis of whether retroactive billing for past costs is permissible.
- The 'Sezione 19' of the Integrated Water Service Regulation establishes that the contract between Abbanoa and users is governed by the tariff system determined by the Regulatory Authority, forming a core basis for the dispute over cost recovery and billing practices.

Passage Text
- Il dies a quo della prescrizione, pertanto, non decorre da "ogni scadenza del periodo di commisurazione del consumo stesso", ma va individuato nel giorno in cui il credito è divenuto liquido ed esigibile da parte di Abbanoa, coincidente con la data in cui quest'ultima è stata autorizzata alla fatturazione dei conguagli regolatori nella misura effettivamente quantificata, ossia, il 26.06.2014.
- In virtù delle funzioni di regolazione del settore (art. 21, commi 13 e 19 del D.L. n. 201/2011, conv. con modificazioni dalla L. 22 dicembre 2011, n. 214), l'AEEGSI (oggi ARERA) con deliberazione del 27 dicembre 2013 n. 643/2013/R/IDR ha approvato il nuovo "Metodo Tariffario Idrico", ove, tra l'altro, sono state definite le componenti dei costi ammissibili sulla base dei quali procedere alla definizione del nuovo sistema tariffario.
- L'AEEGSI ha affidato ai singoli Enti d'Ambito, dislocati a livello regionale, la complessiva quantificazione degli importi in argomento, tenuto conto che tali Enti detenevano i dati e le risultanze contabili delle singole gestioni, riferite agli anni precedenti.
