Question juridique clé
Whether an appeal is admissible against the Federal Criminal Court complaints chamber decision confirming the Federal Prosecutor's competence in a war-crimes investigation.
Solution extraite
No extraordinary appeal lies; Article 79 LTF makes such complaints-chamber decisions inadmissible unless they concern coercive measures, which this one does not.
Motifs extraits
The contested decision is incidental, not final, and the legislature deliberately excluded review to preserve the workload-reducing effect of transferring functions to the TPF. None of the invoked arguments—immunity, alleged nullity, importance of the legal question, equality with cantonal procedures, or analogy to other LTF exceptions—creates an unwritten exception.
