Italy's Constitutional Court has upheld a €507.8 million windfall tax assessment against Eni Global Energy Markets, confirming the state's authority to levy extraordinary contributions on energy firms during the 2022 price surge.
The ruling, published on Saturday, validates Article 37 of the 2022 decree-law that mandated the 'extraordinary contribution against high bills,' effectively closing a legal challenge by the state oil major.
The decision carries significant implications for Eni's (ENI.MI) balance sheet and sets a broader precedent for how Italian energy companies must navigate retroactive fiscal claims.
By rejecting Eni's arguments, the court has reinforced the government's stance that windfall profits generated during the energy crisis were subject to mandatory redistribution to offset household and business costs.
This legal certainty removes a lingering overhang that had kept the liability in limbo for years.
The case centers on the 2022 decree-law introduced to mitigate the impact of soaring energy prices following the geopolitical shock in Eastern Europe.
