Questione giuridica chiave
Whether the cantonal decision refusing jurisdiction in a divorce case was a 'main judgment' under Art. 58 OG
Decisione estratta
No. A main judgment exists only if the decision finally determines the substantive claim and creates res judicata on that claim; a jurisdictional refusal does not do so.
Motivazione estratta
The lower court decided only a procedural prerequisite, namely competence under Art. 5 of the divorce convention. The actual divorce merits under the convention were not decided, so the ruling has no res judicata effect on the divorce claim.
