Background
Mr. [T], aged 76 and in poor health, owned adjoining plots of land classified as a natural zone (zone N) under the local urban development plan (PLU) of the commune of Brie-Comte-Robert, near Paris. He had been living on those plots for many years together with Ms. [E], having installed mobile homes, modular units, shelters, concrete slabs and platforms, storage areas, containers, a caravan, and various vehicles — none of which had received any planning authorisation.
The commune brought emergency injunction proceedings (référé) against Mr. [T] and Ms. [E], arguing that the structures were built without authorisation and in direct violation of the zone N designation, which reserves the land for natural and woodland use. The Paris Court of Appeal (Pôle 1, Chamber 2), in a judgment of 18 November 2021, granted the commune’s application. It ordered the demolition of the fixed structures and removal of the moveable items, the expulsion of the occupants after a one-year grace period from service of the decision, and restoration of the land to its natural wooded state.
Mr. [T] appealed to the Court of Cassation on two grounds. The first ground was dismissed without detailed reasoning as manifestly incapable of leading to quashing. The second ground — the sole substantive issue before the Court of Cassation — argued that the Court of Appeal had violated Article 835 of the Code of Civil Procedure and Article 8 of the European Convention on Human Rights (ECHR) by ordering measures that constituted a disproportionate interference with his right to respect for private life and home.
The Court’s Holding
The Court of Cassation rejected the appeal in its entirety. It reaffirmed that a judge hearing urgent applications (juge des référés) may, under Article 835(1) of the Code of Civil Procedure, order measures to bring an end to a manifestly unlawful interference — including interference arising from construction works carried out in breach of planning rules — and that the judge has sovereign discretion in selecting the appropriate measure, subject to the proportionality requirement imposed by the ECHR.
The Court held that the Court of Appeal had properly exercised that discretion. It had acknowledged Mr. [T]’s vulnerability — his advanced age and health problems — and the fact that he had lived on the land for many years. Rather than treating those circumstances as grounds to refuse enforcement, it structured the order to mitigate the impact: demolition and removal were deferred until the date of eviction, and eviction itself was suspended for one year from service of the judgment. The Court of Cassation found that this carefully calibrated order, so modulated in time, did not constitute a disproportionate interference with the rights guaranteed by Article 8 ECHR, measured against the general-interest imperatives of planning legislation.
The Court explicitly rejected Mr. [T]’s argument that the Court of Appeal had improperly used the deferral period as a factor in assessing the gravity of the interference. In the Court of Cassation’s analysis, taking account of the grace period granted was not an error of law but precisely the kind of proportionality balancing that Article 8 requires.
Key Takeaways
- A référé judge may order demolition and eviction of unauthorised structures built in a protected natural zone; the existence of a manifestly unlawful breach of planning rules is sufficient to trigger the court’s power under Article 835 CPC, even when the occupant has lived there for many years.
- Article 8 ECHR does not block enforcement against unauthorised occupation of a protected natural zone, but it does require the court to ensure proportionality — which may be achieved by structuring the order with a meaningful grace period rather than by refusing or indefinitely suspending enforcement.
- When assessing proportionality, courts may legitimately weigh a deferred execution date as a mitigating factor that reduces the severity of the interference with the occupant’s private and family life, even where the occupant is elderly or in ill health.
- The Court of Cassation will not substitute its own assessment of proportionality for that of the Court of Appeal where the lower court properly identified and weighed the relevant facts; the sovereign appreciation of the appropriate measure belongs to the judge on the merits.
Why It Matters
This decision clarifies the relationship between urgent injunctive relief in planning enforcement cases and the procedural safeguards demanded by Article 8 ECHR. French municipalities routinely face situations in which unauthorised structures have been occupied for years by vulnerable individuals. The ruling confirms that long occupation and personal vulnerability do not per se render enforcement disproportionate: courts can and should calibrate the timing of orders to respect human-rights constraints while still vindicating the public interest in planning law compliance.
The judgment is published (FS-B), signalling that the Court of Cassation intends it to serve as guidance for lower courts. Practitioners advising communes on enforcement, or occupants resisting demolition orders, will need to focus their proportionality arguments on the structure of any grace period rather than on seeking to defeat the enforcement order outright — unless the personal circumstances are so exceptional that no reasonable deferral could adequately mitigate the interference.
