Milan ruling could reshape San Siro investigation

A ruling in a separate Milan planning case could have significant consequences for the investigation into the sale of San Siro and surrounding land to AC Milan and Inter.All defendants in the Torre Milano case were acquitted, with the court addressing how planning rules were interpreted and applied by local officials when permits were approved.The judgment indicated that prosecutors must establish more than a disputed or subsequently challenged interpretation of planning law. They must show that the interpretation used at the time was clearly and demonstrably incorrect.That principle could become important in the San Siro inquiry, which is examining procedural decisions, documentation and the actions of municipal officials, advisers and club representatives involved in preparing the transaction.The investigation has created a fresh layer of uncertainty around one of Italian football’s most consequential infrastructure projects.AC Milan and Inter agreed to acquire the stadium and surrounding land from the City of Milan as part of plans to build a new jointly owned venue next to the existing ground.Control of the site would allow the clubs to increase matchday, hospitality and non-football revenues while reducing their dependence on a municipally owned stadium with limited premium inventory.The Torre Milano ruling does not automatically end the San Siro investigation. Prosecutors will still assess whether the sale process complied with public asset, planning and administrative requirements.Evidence obtained from mobile phones and private communications is another central issue.Defence lawyers have questioned how some material was collected and analysed, while previous court findings have emphasised that searches of electronic devices must be proportionate and clearly defined.Some private communications were excluded from the Torre Milano proceedings. A similar decision in the San Siro case could reduce the evidence available to prosecutors.AC Milan and Inter are continuing project preparations despite the inquiry. Further architectural and design details are expected after the summer, with both clubs maintaining that the development remains on schedule.The new stadium would be constructed alongside the current San Siro rather than on a separate site.Part of the existing venue is expected to be retained and converted for other uses after the replacement stadium opens, although the extent of demolition remains politically and commercially sensitive.Alternative plans have proposed preserving a larger section of the ground for concerts and major events. Such an approach could increase redevelopment costs and create competition with the new stadium’s non-matchday business.Demolition costs are also reported to have risen beyond earlier assumptions, adding another variable to the project’s final budget and financing structure.The clubs need a modern venue to narrow the revenue gap with leading European competitors, but they require legal certainty before committing fully to construction and long-term debt.San Siro is also relevant to Italy’s preparations for UEFA Euro 2032, which the country will co-host with Türkiye. Italy must demonstrate credible progress on five tournament-standard venues as UEFA assesses its final stadium plan.A prolonged investigation could therefore affect both the Milan clubs’ commercial strategy and the wider national infrastructure programme.The Torre Milano acquittals may give the clubs and municipal authorities greater confidence, but the San Siro transaction will remain exposed until prosecutors complete their review or the courts determine whether the evidence is sufficient to proceed.
