Key legal question
Whether the cantonal court correctly refused to hear an unreasoned appeal filed within time but reasoned only after the deadline.
Extracted holding
A late-filed appeal reasoning is inadmissible; the appeal deadline for summary-procedure decisions cannot be extended, and Article 132 ZPO does not permit curing a missing substantive reasoning after expiry.
Extracted reasoning
Under Articles 321(2) and 144(1) ZPO, the appeal must be filed in written and reasoned form within the statutory deadline. Statutory time limits, including appeal deadlines, cannot be extended. Article 132 ZPO only cures formal defects, not an insufficient or missing reasoning.
