Key legal question
Whether the appeal against the cantonal decision refusing restoration of the response deadline was admissible under Art. 93 LTF
Extracted holding
The appellant failed to show an irreparable legal harm; the decision was therefore not appealable.
Extracted reasoning
The court held that mere procedural disadvantage, delay, or increased costs are not irreparable harm. The appellant did not explain the procedural consequences of failing to file the response or show that it could not still remedy the omission during the proceedings.
