Kernrechtsfrage
Whether the employer-liability claim under Art. 52 AHVG was time-barred
Extrahierter Entscheid
The claim was not time-barred because the Kassse did not yet have sufficiently certain knowledge of the damage from the 20 April 2004 circular; the limitation period started only with the inspection of the collocation plan in September 2006.
Extrahierte Begründung
Damage knowledge requires a sufficiently concrete, reasonably estimable loss and awareness of the liable person. The bankruptcy circular hinted at possible losses but did not clearly and unequivocally establish that second-class creditors would probably suffer a total or quantifiable loss.
