Key legal question
Whether the guardianship decision was void because the persons to be placed under guardianship were not properly heard under Art. 374 ZGB.
Extracted holding
Yes. The mandatory hearing requirement of Art. 374 ZGB was violated, so the guardianship order could not stand.
Extracted reasoning
Art. 374 ZGB is mandatory. A single missed summons does not justify dispensing with the hearing; the authority should have issued a further summons, possibly with warning of police escort. The affected persons must be informed of the specific facts relied upon.
