Question juridique clé
Whether the insurer had to grant or renew a short deadline to cure the missing objection grounds after refusing an extension request.
Solution extraite
A procedural deadline set by the insurer is extendable on request for sufficient reasons; if extension is refused, at least a short additional deadline must be granted to file the objection grounds, absent obvious abuse.
Motifs extraits
Art. 10 Abs. 5 ATSV is interpreted like the analogous ATSG and earlier AHV rules: deficient objections must generally be cured by deadline, and stricter requirements would be incompatible with the purpose of the objection procedure. Work overload is an accepted reason for extension; the case showed no obvious abuse.
