Question juridique clé
Whether the public-law appeal against the GIAR's decision was admissible under Art. 87 OG despite being directed against an incidental criminal decision.
Solution extraite
The challenged decision was incidental, and the appellant failed to show irreparable legal harm as required by Art. 87(2) OG.
Motifs extraits
Any delay, costs, or inconvenience from the criminal proceedings were only factual disadvantages; the alleged constitutional violations could still be reviewed later, including in an appeal against a final cantonal conviction.
