Question juridique clé
Whether the federal public-law appeal was admissible against the cantonal court's inadmissibility ruling
Solution extraite
The appeal was admissible only as to the question whether the cantonal appeal was wrongly declared inadmissible; the merits could not be reviewed at this stage.
Motifs extraits
The Federal Supreme Court may review the cantonal court's refusal to enter into the case, but if the appeal succeeds the matter must be remitted for a merits decision.
