Question juridique clé
Whether the appellant was liable under Art. 52 AHVG for unpaid social security contributions owed by the bankrupt company.
Solution extraite
Yes. As managing shareholder with sole signature, he had grossly negligent conduct in failing to ensure payment and reporting of the contributions.
Motifs extraits
The company paid contributions late from the outset and failed to report the substantial 2005 wage increase. These violations of contribution and reporting duties were imputable to the appellant as responsible corporate organ.
