Question juridique clé
Admissibility of the public law appeal and subsidiary constitutional appeal against a cantonal decision by an investigating judge
Solution extraite
The decisions were inadmissible because the challenged act did not originate from a superior cantonal court within the meaning of Art. 86 para. 2 LTF.
Motifs extraits
The investigating judge is not a superior judicial authority; his decisions are generally subject to cantonal appeal. Since the challenged measure is a public law matter and no federal exception applies, the Federal Supreme Court cannot hear the matter directly.
