Question juridique clé
Whether the public-law appeal against the cantonal interlocutory decision was admissible without irreparable legal harm.
Solution extraite
No irreparable legal harm was shown; the appeal could not proceed against this interlocutory decision.
Motifs extraits
Under Art. 87(2) OJ, an interlocutory decision is appealable only if it may cause irreparable legal prejudice. The refusal to provide further details on the charges at the investigation stage did not create such prejudice, especially since the appellant had already been questioned and could still present useful defensive motions.
