Questione giuridica chiave
Whether Art. 6 of the Swiss–US treaty applied to a creditor's claim against heirs.
Decisione estratta
No. The treaty governs only disputes among heirs or competing inheritance claimants over succession to estate assets, not claims by estate creditors against heirs.
Motivazione estratta
Creditors are not 'claimants of an inheritance' because they assert no right to the inheritance as such; the treaty text is therefore incompatible with the appellant's reading.
