Key legal question
Whether supplementary extradition to Germany was admissible despite the appellant's objection that dual criminality was lacking under Swiss law.
Extracted holding
The alleged conduct is punishable in both states, at least as fraud and forgery under Swiss law; dual criminality is satisfied.
Extracted reasoning
Dual criminality does not require identical offences, only punishability in both states. The conduct described falls within Art. 146 StGB and Art. 251 StGB in Switzerland and fraud under German law.
