Kernrechtsfrage
Whether the insurer's answer contained a counterclaim for repayment or only a set-off declaration.
Extrahierter Entscheid
The filing did not amount to a counterclaim; it was only a declaration of set-off against the claimant's back-pay claim.
Extrahierte Begründung
The pleading never used the term counterclaim and, read in good faith, showed that the insurer believed it did not need to sue to assert repayment. The cantonal court therefore misread the pleading.
