The Town of Le Pecq received notification of two rulings from the Administrative Court of Appeal rejecting Auchan and Carrefour's appeals against the Cœur de ville project.

The Town of Le Pecq today received notification of two rulings from the Administrative Court of Appeal following the hearing held on September 24. In both cases, the appeals filed by Auchan and Carrefour against the Cœur de ville project have been rejected.
This decision represents a significant step forward for the municipality, confirming the validity of the issued permits and strengthening the project's legal standing. It also reflects the work carried out over several years by the Town and its partners.
The appellants still have a period of two months from the notification of the rulings to file an appeal with the Council of State. However, such a move would not lead to a new review of the project's substance. The Council of State only verifies the correct application of the law by the previous court. In other words, the building permit, as issued and validated by the Administrative Court of Appeal, would not be re-examined in its content.
A new stage has thus been reached in the realization of the Cœur de ville, allowing the Town and its partners to confidently pursue this project long-awaited by the residents of Le Pecq.
