Key legal question
Whether the constitutional complaint could challenge the application of Art. 3(2) ZGB on due care and good faith
Extracted holding
No; the due-care assessment under Art. 3(2) ZGB is a question of law reviewable by ordinary appeal, so the constitutional complaint was inadmissible to that extent.
Extracted reasoning
The appellant's criticism targeted legal assessment rather than a constitutional defect; such issues fall outside the scope of the staatsrechtliche Beschwerde.
