Motifs extraits
The special rule in Art. 41bis para. 1 let. f RAVS governed self-employed contribution adjustments and remained applicable despite the LPGA. Interest is due independently of any reminder, formal notice, or the insureds' good faith. The finding that the appellants failed to provide timely information, causing deviations above 25% between advances and final contributions, bound the Federal Supreme Court.
