Abstract

"Company A, a Germany entity, and company B, a Polish entity, were in dispute regarding an international sales of goods contract. A was seeking damages for breach of contract, together with interest. The Supreme Court had to decide which rate of interest applied. It ruled that this had to be determined according to the lex contractii stipulated by the conflict of laws rules for the seat of the court.

The justification of the judgment showed that B tried to rely on UNIDROIT Principles (although the specific provision was not mentioned) to justify its position on the level of interest.

The court ruled that private codifications, such as the UNIDROIT Principles or the Principles of European contract law, may not be used, even as a secondary source of law, that they are external to CISG, and that they are not relevant for a state court which must rule based on the law. If the court had applied Articles 7.4.9 and 7.4.10 of the UNIDROIT Principles, it would have assessed the applicable interest rate differently."
