Kernrechtsfrage
Whether the federal appeal met the reasoning requirements and was timely filed under the Federal Supreme Court Act.
Extrahierter Entscheid
The appeal did not contain a sufficient legal reasoning and was therefore inadmissible; the filing deadline had also expired without a curative supplement.
Extrahierte Begründung
The initial letter of 21/23 April 2011 did not satisfy Art. 42(2) BGG. Despite being informed and given the opportunity to submit a corrected brief, the appellant filed nothing further. The court therefore applied the simplified non-entry procedure under Art. 108 BGG.
