Penalty Clause Validity Upon No Actual Damage

The case involved a challenge to a lower court's decision which had upheld the validity of a contractual clause imposing a financial penalty upon the failure to meet a specific performance deadline, despite the actual damage suffered being lower than the stipulated penalty. The highest court quashed the lower court's ruling, reasoning that under the relevant civil code provision, a stipulated penalty clause is considered null and void when the obligee has suffered no actual damage, as the clause constitutes an illegitimate enrichment where no loss has occurred, regardless of the contractual agreement between the parties.
