Key legal question
Whether the appellant was liable under Art. 52 LAVS for damage caused by unpaid AVS contributions.
Extracted holding
Yes. As sole administrator, he committed grave negligence by retaining wage deductions without remitting them and by failing to supervise or act.
Extracted reasoning
Lack of business training and reliance on an accountant did not excuse him. In a small company, an sole administrator must supervise essential matters, including social insurance contributions. He had been expressly warned by the fund and knew or should have known of the arrears; his prolonged passivity was causally linked to the loss.
