Can a city hall's pre-emption order be overturned?

Yes, the decision to pre-empt may be the subject of an application for annulment if the City Hall no longer has the objective of carrying out an urban development operation of general interest.

This can be verified by consulting the building permit present at the location of the pre-empted property.

The request for cancelation must be made within 5 years from the date of acquisition of the property by the City Hall.

As a former owner of the dwelling or someone who intended to purchase the pre-empted property, you can to appeal to the administrative tribunal.
