Key legal question
Whether the appeal was filed within the 30-day deadline
Extracted holding
The appeal was late because the notification was deemed served on 2012-12-28 and the deadline expired on 2013-02-01.
Extracted reasoning
Under Art. 100(1), 44(2), 45(1) and 46(1)(c) BGG, the failed first delivery attempt on 2012-12-21 triggered deemed service on the seventh day; the later collection on 2013-01-03 did not affect the deadline.
