Key legal question
Whether the missed deadline for the court advance should be restored under Art. 35 OG.
Extracted holding
No. The complainant did not show an excusable, non-fault-based obstacle preventing timely action.
Extracted reasoning
The error in operating the computer and the resulting failed payment order were attributable to the complainant. Delayed notification by Postfinance was also attributable to him as conduct of an auxiliary person.
