Questione giuridica chiave
Whether the appeal was admissible under Art. 58 OG because the challenged decision was a main judgment.
Decisione estratta
The challenged decision was only an enforcement decision on exequatur, not a final decision on the substantive claim; therefore it was not a main judgment.
Motivazione estratta
The Basel appellate court decided only whether the foreign divorce judgment could be enforced in Basel, not whether the defendant was substantively obliged under civil law to hand over the child. The legal nature of the decision, not its civil-judgment form, is decisive.
