Question juridique clé
Whether a Swiss summons to a foreign-resident accused may be enforced by procedural sanctions for nonappearance.
Solution extraite
No. A summons addressed to a person residing abroad operates only as an invitation; Swiss authorities may not coerce appearance abroad.
Motifs extraits
Swiss coercive powers are territorially limited and may not be used in a foreign state without that state's cooperation. Otherwise sovereignty and the protection of extradition law would be circumvented.
