Question juridique clé
Whether the appellant is liable under Art. 52 AHVG for unpaid federal social insurance contributions
Solution extraite
Yes. The company failed for a long period to pay and account for wages-related contributions, and this grossly negligent conduct is attributable to the appellant as sole board member.
Motifs extraits
The company paid substantial wages without remitting the corresponding contributions despite repeated reminders and enforcement measures; the appellant's sustained passivity and supervisory role justified attribution of the fault.
