Questione giuridica chiave
Whether the parents of a legally represented minor party were admissible as witnesses under Lucerne procedural law.
Decisione estratta
No. Because the minor acted through her parents as legal representatives, they had to be heard as parties and were therefore not witness-competent.
Motivazione estratta
Allowing them as witnesses would empty § 157(3) ZPO/LU of content. Cantonal law governs admissible evidence, and no violation of federal law or the ECHR was shown.
