Decisione estratta
No. The register entry reflected the applicable law and the information available to the civil registrar; no obvious mistake existed.
Motivazione estratta
Administrative correction under Art. 43 ZGB is limited to clear, undisputed errors apparent from the documents and information then available. Here, Swiss law applied and Art. 270(2) ZGB required the surname of the unmarried mother.
