Questão jurídica principal
Whether the cantonal authority rightly refused to restore the complaint deadline under Art. 33(4) SchKG
Decisão extraída
Yes. The request was insufficiently substantiated because no evidence of a qualifying impediment, such as a severe sudden illness, was provided.
Fundamentação extraída
Restoration requires an unforeseeable, non-attributable obstacle preventing timely action. The applicant must plead and support the request with evidence; the authority need not investigate unproven assertions on its own.
