A new point in favor of the class action lawsuit against the bill adjustments requested by Abbanoa . The Cagliari Court of Appeal, civil division, has rejected the suspension request of the company that manages the water service in Sardinia. Abbanoa had appealed the first-instance ruling that declared the payment requests made to customers between 2005 and 2011 "undue."

The decision

According to the judges, the reasons advanced by the company for requesting the suspension of the first-instance sentence do not highlight "critical issues" such as to warrant an assessment of the "manifest merits of the appeal."

In fact, the conditions for admitting the appeal are lacking: "For the Court of Appeal," states Mauro Pili , who filed the class action with the Unidos movement, "Abbanoa's appeal does not show sufficient evidence to seriously challenge the first-instance ruling." "The requirement of 'serious and irreparable harm' is not met," he continues, "and Abbanoa's attempt to argue that the ruling would have unsustainable effects on the budget was also soundly rejected. Abbanoa continues to lose because it continues to defend the indefensible instead of compensating citizens ."

Abbanoa's reply

The company's response was swift, emphasizing: "The Cagliari Court of Appeal ruled exclusively on the suspension of the first-instance ruling in the class action, not on the merits of the case. The judges emphasized—as stated in a statement—that 'the non-final ruling, issued in the context of a class action, does not contain an immediately enforceable decision.' Therefore, even from a practical perspective, this order does not entail any obligation to repay the class action parties."

In December 2025, the second section of the Cagliari Court accepted the appeal of approximately twelve thousand Sardinians against the water management company , who had requested a total refund of nearly 106 million euros from users.

The judges had stated that "the sums requested for previous 'balance payments for the years 2005-2011' submitted by water service users who promptly joined the proposed class action are not due."
