Questione giuridica chiave
Whether the reaffiliation procedure required a summons by the AVS compensation fund and whether the employer could be charged the reaffiliation costs.
Decisione estratta
In the reaffiliation context, the AVS compensation fund is not involved; the institution supplétive may act under Art. 11 para. 3bis LPP and charge the employer its administrative costs.
Motivazione estratta
The amended Art. 11 para. 3bis sentence 2 LPP excludes compensation-fund intervention in reaffiliation. The lower court wrongly relied on Art. 11 para. 5 LPP, which governs initial affiliation, not reaffiliation.
