Kernrechtsfrage
Whether the pension fund could recover unpaid contribution arrears, interest, and contractual fees from the employer.
Extrahierter Entscheid
The claim was upheld for CHF 14,436.30 plus 5% interest from 2016-05-01 and CHF 600 processing fees.
Extrahierte Begründung
The contribution invoices, premium credit, and account statement sufficiently proved the debt; the contract and cost regulations also supported the fee claims, and statutory default interest applied.
