Questione giuridica chiave
Whether the appeal could succeed on the argument that the appellate court should have found an exit date of 31 October 1997 or otherwise applied the trust principle / contract supplementation to fix a different departure date.
Decisione estratta
No. The Federal Court held that the cantonal court correctly refused to base its decision on a departure date not pleaded by either party; the trust-principle and contract-supplementation arguments could not be used to override the binding factual findings and the pleading maxim.
Motivazione estratta
The plea of violation of the trust principle relied on facts not supported by the binding record. The question of judicial contract supplementation did not arise where the dispute was when the contractual relationship was actually terminated by the parties. The alleged breach of the cantonal pleading maxim was not reviewable on appeal as such.
