Kernrechtsfrage
Whether the uncollected summons and later ordinary mailing constituted valid service for the first notice of proceedings.
Extrahierter Entscheid
No. A court document that first informs a party of proceedings must be actually delivered; a fictional service based on an uncollected notice is insufficient.
Extrahierte Begründung
Under the cantonal rules, service presupposes delivery to the addressee where possible. Fictional service may be accepted only in limited situations, such as where a party has itself initiated proceedings and must expect court mail, or where there is proven refusal to accept delivery. None of that was shown here.
