Questione giuridica chiave
Whether the Turkish judgment of 25 March 1999 had res judicata effect in Switzerland under the LDIP.
Decisione estratta
Yes. The Turkish decision was final and, under Turkish law as found by the cantonal court, barred a later ordinary action on the same claim.
Motivazione estratta
The court held that the challenge was in substance against the cantonally established content of Turkish law, which cannot be reviewed in reform proceedings in a pecuniary dispute. On the facts as found, the Turkish opposition-removal procedure allowed the parties to present the same arguments and evidence as in ordinary proceedings and precluded relitigation of the same claim.
