Key legal question
Whether the appeal against the cantonal debt-enforcement decision was filed in time.
Extracted holding
The appeal was filed after the 10-day federal deadline and is therefore manifestly inadmissible.
Extracted reasoning
The cantonal decision was served on 2013-02-20, so the deadline expired on 2013-03-22; filing on 2013-04-08 was late. Any reliance on the incorrect 30-day indication could be left open because even that period was missed.
