Key legal question
Whether the appeal against the cantonal exequatur decision was admissible before the Federal Supreme Court.
Extracted holding
The appeal was not admissible because the cantonal exequatur procedure must be conducted with a two-instance cantonal review; the attacked decision was issued by a single cantonal instance.
Extracted reasoning
Art. 106 IRSG and Art. 80 BGG require a two-tier cantonal route for exequatur decisions. Art. 55(4) StPO does not displace that special regime.
