Kernrechtsfrage
Whether the extradition treaty with Argentina excludes applying Swiss domestic law to offences not listed in the treaty.
Extrahierter Entscheid
No. Swiss domestic extradition law may supplement the treaty where it allows cooperation on more favourable terms.
Extrahierte Begründung
The Court reaffirmed the 'principle of favour': a treaty does not bar extradition under Swiss law for offences not expressly listed, absent an express or implied limitation.
