The European Public Prosecutor's Office (EPPO) is investigating the European Commission over the sale of Commission buildings to Belgium's state fund, with authorities reportedly conducting searches of Brussels offices.

In a late-April 2024 announcement, the SFPIM was set to acquire 23 buildings for about €900 million as part of the broader redevelopment transaction.

The Commission says the sale followed established procedures and that the process was conducted properly, while the EPPO pursues the probe to protect procedural integrity.

Context on Hahn’s career shows he previously served as Austria’s regional policy commissioner and science minister, and later as the EU’s Cyprus envoy after leading von der Leyen’s first commission.

At this stage, no further details are provided about potential charges or outcomes.

The investigation centers on Hahn’s tenure as budget commissioner and the real estate deal overseen by his office, with no charges disclosed yet.

The sale was valued at about €900 million.

Turkish Cypriot leadership had previously opposed Hahn’s appointment, highlighting sensitivities around EU involvement in Cyprus politics.

The sales occurred during the tenure of former Budget and Administration Commissioner Johannes Hahn (2019–2024), who later became the EU’s Cyprus envoy.

The Commission still employs around 30,000 staff and owns roughly 60 Brussels buildings.

Brussels’ finance arm estimated transformation costs to be of a similar scale to the acquisition, nearing €2 billion.
