Kernrechtsfrage
Whether the missing documents justified a suspension of supplementary benefits under Art. 43 ATSG.
Extrahierter Entscheid
Yes. The requested documents were relevant to assessing entitlement, proper reminders and warnings had been issued, and the claimant did not provide the remaining documents.
Extrahierte Begründung
The court held that the insurer may, after prior written warning and a reasonable deadline, either decide on the file or discontinue inquiries and refuse to continue the claim process when required information is withheld without excuse. Because the outstanding documents concerned entitlement-relevant circumstances and the facts could not be reliably established otherwise, the suspension was lawful.
