Penalty Clause: Types, Validity and the Court of Cassation's Approach

For an alternative penalty, unless the contract indicates otherwise, the creditor may choose performance or the penalty (TBK m.179/1). There is no general requirement to demand actual performance first; the conditions for the election and maturity of the penalty still apply.

A penalty for performance at the wrong time or place may generally be claimed alongside performance, provided the creditor has neither expressly waived it nor accepted performance without reservation (TBK m.179/2). Reservations in a delivery record therefore matter.

Rescissory (withdrawal) penalty (TBK m.179/3): the debtor reserves the right to rescind by paying the penalty. After paying, the debtor is released from performance; the creditor cannot demand performance.

The creditor may demand the agreed penalty even without having suffered any damage (TBK m.180/1). This is the key feature distinguishing the penalty clause from classical damages: the creditor need not prove the damage.

However, if the creditor's actual damage exceeds the penalty, the excess can be demanded only on proof of the debtor's fault (TBK m.180/2). The penalty thus operates as a guaranteed minimum; it accrues to the creditor even where the actual damage is less.

The court reduces, on its own motion, a penalty it finds excessive (TBK m.182/3). This rule is mandatory; the parties cannot waive it in advance. The Court of Cassation evaluates the amount of the penalty, the debtor's economic position, the value of the performance and the gravity of fault.

The position differs for contracts between merchants. Under TCC m.22, a debtor who is a merchant cannot demand reduction of an excessive penalty; however, the provisions on contracts contrary to morals (TBK m.27) are reserved. Penalty rates must therefore be set carefully from the outset in B2B contracts.

A penalty clause is accessory to the principal obligation. It cannot be claimed if that obligation is invalid or, unless otherwise agreed, becomes impossible for a reason for which the debtor is not responsible (TBK art.182/2). An accrued penalty is not necessarily extinguished merely because the principal obligation is later performed. For a penalty tied to the time or place of performance, waiver and acceptance of performance without a reservation must be assessed separately.

Special limitations apply in labour law: a penalty stipulated solely in favour of the employer breaches reciprocity, and unilateral penalty clauses in employment contracts are frequently held invalid by the Court of Cassation's 9th Civil Chamber.

In contractual disputes, not only the signed text but also offer correspondence, revision history, invoices, delivery records, payment records, formal notices and the parties' subsequent conduct are taken into account. The formation, performance and termination of a contract often acquire meaning only through these ancillary documents.

Form requirements, authority of representation, penalty clauses, exclusion-of-liability provisions, standard terms and consumer-protection rules may all affect the validity or enforceability of a contract. For standard terms, the requirements of clear information, an opportunity to learn their content and acceptance under Article 21 of the Code of Obligations must be considered, together with any special consumer rules.

Before any dispute arises, the scope of obligations, delivery date, defect notice, default notice, interest and competent-court clauses should be drafted explicitly. Vague provisions may give rise to interpretation disputes and to difficulties of proof later on.
