Questione giuridica chiave
Whether the appellant was liable under Art. 52 AHVG for unpaid 2001 social security contributions despite his resignation before the final invoice.
Decisione estratta
Yes. Liability remained because the decisive omission was the failure to report the substantial wage-sum increase during 2001, which caused the loss and occurred before his resignation.
Motivazione estratta
Contribution debts arise ex lege with wage payment; the company breached reporting and payment duties, and the omitted wage-sum notification would likely have led to adjusted advance payments in time. The damage was causally linked to conduct before the appellant left office.
