Question juridique clé
Whether the hospital's liability can be based on a loss-of-chance theory despite lack of proven natural causation to the final harm.
Solution extraite
Swiss law does not compel recognition of a compensable loss-of-chance claim in this state-liability setting; the cantonal court was not arbitrary in refusing it.
Motifs extraits
Loss of chance conflicts with the ordinary Swiss concept of natural causation and with the restrictive use of Art. 42(2) CO, which presupposes a practically certain damage. The chance itself is not treated as patrimonial damage in this context.
