Question juridique clé
Whether the arrest requisites under Art. 272 LP were made plausible, especially the existence of the bank's claim
Solution extraite
The bank did not make plausible an existing claim: at most, a future claim could arise if it were later held liable to the heirs, and such a future or merely expected claim cannot justify an arrest.
Motifs extraits
The alleged damage did not yet burden the bank's patrimony; the asserted recourse claim against the alleged wrongdoer would arise, if at all, only upon payment or at least was not yet born. The cantonal court was therefore not arbitrary in denying the required plausibility of a current claim.
