Kernrechtsfrage
Whether the appeal was filed within the statutory 30-day deadline.
Extrahierter Entscheid
The appeal was filed out of time because the deadline began on 23 February 2011 and expired on 25 March 2011; filing on 14 April 2011 was late.
Extrahierte Begründung
The 30-day BGG deadline is statutory and non-extendable; an absence abroad does not suspend it or justify restoration here. Under service rules, the deadline starts at the latest seven days after the first unsuccessful service attempt, and postal filing is timely only upon delivery to the Swiss Post.
