Kernrechtsfrage
Whether the damage decision had to be re-served or reopened because service was defective
Extrahierter Entscheid
No. The appellant learned the decision and the service defect in November 2008 at the latest, so he could and should have filed an opposition within 30 days; no basis existed for re-service, reopening, or remittal.
Extrahierte Begründung
A lack of proper service did not amount to nullity here, because the appellant had later knowledge and thus no irreparable loss of the right to object. Nullity is reserved for cases where the addressee never learns of the decision or cannot participate at all.
