Question juridique clé
Whether the cantonal court arbitrarily interpreted the 1 September 1993 letter as requiring a debt acknowledgment for the claim now pursued
Solution extraite
Yes. The letter's second condition covered only properties sold privately, not claims arising from forced realization and the resulting insufficiency-of-pledge certificate.
Motifs extraits
The text of the letter referred expressly to objects sold 'de gré à gré'; the file contained no decisive indication that the parties meant forced enforcement sales as well. The cantonal court's broader reading was untenable.
