Meter Tampering and Consumption Reconstruction: Clarifications from the Reggio Calabria Court of Appeal
The Reggio Calabria Court of Appeal, in Judgment No. 985 of 24 September 2024, addressed the critical issue of reconstructing electricity consumption following meter tampering (manomissione del contatore). The ruling clarifies that, within the framework of European and national regulations on energy market liberalisation, the metering data provided by the local distributor constitutes reliable evidence of the energy actually supplied.
The Court ruled that such evidence can only be challenged by the user through reasoned and documented objections, such as photographic evidence of the meter or clear proof of measurement inconsistencies. This decision reaffirms the central role of the Distribution Network Operator (DNO) in managing and recording consumption and confirms the effectiveness of the POD (Point of Delivery) identification system.
The Legal Framework: Unbundling and Market Liberalisation
The Court of Appeal’s analysis begins with the evolution of the energy market. Since 1993, EU Directives have mandated the unbundling of energy activities to increase competitiveness and prevent monopolistic behaviour.
In Italy, this was implemented through several legislative decrees (e.g., Legislative Decree 79/1999) which separated the transmission and distribution of energy from the retail supply. Under this regime:
- The Distributor (DNO): Manages the physical network, dispatches energy to the point of delivery, and is legally responsible for metering activities (installation, maintenance, reading, and data storage for at least five years).
- The Supplier (Retailer): Handles the commercial relationship with the end-user and issues invoices based on data received from the Distributor.
To ensure transparency, each supply point is uniquely identified by the POD (Point of Delivery) code, a European alphanumeric standard that replaced previous local identification methods.
The Ruling: Evidentiary Value of Metering Data
The central legal question was whether the data reconstructed by the Distributor after detecting meter tampering could be considered definitive.
The Court held that:
"Metering data originating from the Local Distributor (acting as a third party relative to the seller) constitutes prima facie evidence of the gas or electricity actually delivered."
This creates a rebuttable presumption of accuracy. The burden of proof shifts to the user, who must provide specific evidence to invalidate the Distributor’s records. Acceptable forms of rebuttal include:
- Photographic evidence showing readings that contradict the Distributor's records.
- Intrinsic inconsistencies in the recorded measurements over time.
- Evidence that the recorded consumption is disproportionate to the supply capacity, indicating a potential meter malfunction rather than theft.
Practical Implications
This judgment provides essential clarity for both utility companies and consumers. It reinforces the principle that in a liberalised market, the neutrality of the Distributor as a data manager grants its measurements a high degree of legal reliability in court. For legal practitioners, it underscores that generic denials of consumption are insufficient; a successful challenge requires technical documentation and a rigorous critique of the metering equipment's integrity.
