Question juridique clé
Whether the public-law appeal could seek more than annulment, including direct recusal orders against judges not previously seized by the cantonal court.
Solution extraite
The appeal was inadmissible insofar as it went beyond seeking annulment, and the Federal Tribunal could not decide recusal requests not first submitted to the cantonal court.
Motifs extraits
Under settled practice, a public-law appeal must in principle seek annulment of the challenged decision; the Federal Tribunal is not a first-instance body for recusal requests against judges not previously examined by the cantonal authority.
