Key legal question
Whether the federal civil appeal was admissible despite the low amount in dispute because the case raised a question of principle.
Extracted holding
The case did not raise a question of principle within Art. 74(2)(a) LTF; it was only an application of settled law to a particular case.
Extracted reasoning
The Court held that the notion of a principle question must be interpreted very restrictively. The requirements for a special agreement on accessory costs under Art. 257a(2) CO were already settled by abundant case law; the appellants only disputed how that case law applied to their lease clauses.
