Question juridique clé
Whether the suretyship had expired under the 20-year limit of Art. 509(3) CO.
Solution extraite
The suretyship had not lapsed, because the creditor had pursued the surety in time and maintained the proceedings without notable interruption.
Motifs extraits
Art. 509(3) CO extinguishes a personal suretyship after 20 years, but if the creditor initiates enforcement or judicial action against the surety during the last year and proceeds without notable interruption, expiry cannot occur during the pending case.
