Question juridique clé
Whether the public-law appeal was sufficiently reasoned against the cantonal court's subsidiary reasoning on recusal.
Solution extraite
The appellant did not specifically challenge the independent subsidiary reasoning, so the appeal could not be examined.
Motifs extraits
Under the federal motivation requirement, each independent ground of the cantonal decision had to be contested. The appellant failed to address the interpretation and application of Art. 91 let. c LOJ/GE in a sufficiently concrete way.
