Question juridique clé
Whether the appeal against the Federal Criminal Court's decision on access to the file was admissible before the Federal Tribunal.
Solution extraite
The appeal was inadmissible because the challenged decision did not concern coercive measures within the meaning of Art. 79 LTF.
Motifs extraits
The dispute related only to the complainant's access to the file and participation in the proceedings; therefore only a criminal-law appeal existed, but not one against a non-coercive decision of the complaints chamber.
