Parties may advance claims on appeal

Reference decision: French Supreme Court (Cour de cassation) • No. 12-21.809 • 2013-10-09 • View the decision →

This decision provides important clarification on your property law matters. Here is what it means for you.

The situation

Parties may advance on appeal claims that were virtually included in the claims and defences submitted to the first instance judge and add to them all claims that are ancillary to, a consequence of, or supplementary to them. Therefore, a Court of Appeal infringes Article 566 of the Code of Civil Procedure if, in order to dismiss a claim for payment of interest at twice the statutory rate, it holds that this is a new claim and as such inadmissible, when it was supplementary to the compensation claim made at first instance as a principal claim based on Article L. 242-1 of the Insurance Code.

What the law says

This decision confirms the fundamental principles of property law.

Key points

Strictly comply with statutory time limits for appeals
Keep all your supporting documents (title deeds, deeds, correspondence)
Plan ahead: preventive advice always costs less than litigation

Practical use cases

Landlord adding interest claim on appeal for unpaid rent

A landlord in Lyon pursued a tenant for €12,000 in unpaid rent covering 18 months. The first instance court ordered repayment of the principal but denied interest. The landlord appealed, seeking statutory interest at 5% per annum from the due dates, amounting to an additional €1,800.

Practical application:

The Cour de cassation ruling confirms that a claim for interest is supplementary to the original rent claim and thus admissible on appeal under Article 566 of the Code of Civil Procedure. The landlord should immediately request the court of appeal to award interest, arguing it is a direct consequence of the unpaid rent. Ensure all calculations and due dates are documented to support the precise interest amount.

First-time buyer seeking penalty interest on appeal for hidden defects

A first-time buyer in Bordeaux discovered severe water damage from a concealed leak after purchasing a flat for €320,000. At first instance, she claimed €45,000 in repair costs and was awarded €30,000. On appeal, she wishes to add a claim for interest at twice the statutory rate on the awarded sum from the date of the legal action, potentially adding €6,000.

Practical application:

Following the precedent, this interest claim is supplementary to the compensation claim for hidden defects and should not be rejected as new. The buyer's solicitor should promptly file submissions citing Article 566 and arguing that the interest is an accessory to the main damages. Keep a detailed timeline of the defect discovery and legal proceedings to justify the interest period.

Co-owner claiming penalty interest on appeal in charges dispute

In a Parisian co-ownership, a co-owner was ordered by the tribunal to pay €8,000 in overdue service charges. Unhappy with delays in the syndicate's communication, he appealed and sought to claim interest at twice the legal rate on the charges from the date they were due, arguing this would compensate for the syndicate's procedural delays.

Practical application:

The Cour de cassation's decision supports that such a claim is admissible on appeal as it is supplementary to the principal claim for charges. The co-owner must explicitly state in the appellate brief that the interest claim arises directly from the original dispute and is not an entirely new matter. Provide evidence of the syndicate's delays to strengthen the case for penalty interest.
