Questione giuridica chiave
Whether the federal extradition procedure had to be observed before prosecuting Wetzel for this offense.
Decisione estratta
The extradition procedure is required only for offenses for which federal law imposes an extradition duty; it does not apply to other offenses.
Motivazione estratta
Federal case law has consistently limited the procedural protection to extraditable offenses. Since the offense charged was not one for which extradition was mandatory under the Federal Act of 24 July 1852, prosecution could proceed without first requesting extradition from Zurich.
