Questão jurídica principal
Whether the dispute falls within the inheritance-law exclusion of the Lugano Convention.
Decisão extraída
The claim is not an inheritance claim in the relevant sense; inheritance only determines the widow's standing, while the substantive claim is a patrimonial claim belonging to the deceased's estate.
Fundamentação extraída
Claims against third parties are excluded only if they concern rights on and to the estate. Here the alleged claim existed already in the deceased's patrimony; succession is merely a preliminary question and does not remove the case from Lugano's scope.
