Kernrechtsfrage
Whether the complaint showed that the cantonal court's factual findings were manifestly incorrect under Art. 97(1) BGG.
Extrahierter Entscheid
The appellant did not establish that the factual finding was manifestly incorrect; the supporting documents did not concern the specific postal item.
Extrahierte Begründung
The challenged submissions were unrelated to the concrete shipment, so the factual finding could not be shown to be obviously wrong.
