Question juridique clé
Whether the cantonal interim recusal decision could be challenged by public-law appeal or had to be treated as a constitutional complaint
Solution extraite
The filing was treated as a constitutional complaint because the recusal decision concerned only cantonal procedure and lacked the required close connection to a federal administrative-law issue.
Motifs extraits
An interim decision is separately appealable only if the same remedy is available against the final decision and, here, the recusal ruling on cantonal procedural law did not have the necessary nexus with federal administrative law.
