Questão jurídica principal
Whether the cantonal supervisory authority failed to establish the legally relevant fact of when the written objection was handed to the post.
Decisão extraída
Yes. The authority should have determined the posting date because it was decisive for timeliness of the objection.
Fundamentação extraída
The debtor had alleged with evidence that the objection was posted on 2004-03-05. If true, the 10-day period ended that day and the objection would be timely; omitting this finding violated the duty to establish the relevant facts.
