The period of at least 15 days granted

Practical application:

Under the 1970 Court of Cassation ruling, the 15-day period for submitting observations only starts after all individual and collective notices are completed. Here, the simultaneous posting means the period may never have legally started. The landlord should gather proof of exact posting and notification dates, then challenge the expropriation order in the administrative court within 2 months of its notification. Contact a French real estate lawyer to verify the timeline and file an appeal.

Practical application:

The case law requires both individual and collective notice formalities to be fully completed before the observation period runs. Since the buyer didn't receive individual notice, the 15-day clock hasn't started. The buyer should immediately check with the town hall for the exact posting date and request proof of individual notification. If missing, they can still submit observations without being time-barred and seek to annul the expropriation order if it proceeds. Engaging a lawyer early can prevent losing the plot.

Practical application:

According to this ruling, the expropriation order is invalid if the inquiry's observation period started before all individual and collective notices were completed. Here, the lack of individual notification to some co-owners means the procedure was flawed. The co-owner should gather all correspondence, the syndic's records, and proof of posting dates, then challenge the expropriation order before the administrative court within 2 months of notification. Joining forces with other affected co-owners can strengthen the case.
