Key legal question
Whether the employee had to be notified of the contribution decision and allowed to participate before assessing paritary AVS contributions.
Extracted holding
Yes. Because the assessment affected A.________ directly and the amount was significant, the fund and the cantonal court had to ensure he was notified and could be heard.
Extracted reasoning
A contribution decision binds both employer and employee. As a rule, the employee must be notified and able to challenge the assessment whenever salary-related contributions are at stake, subject only to practical exceptions not applicable here.
