Question juridique clé
Whether the public-law appeal was admissible despite the lack of a further cantonal remedy against the mootness and costs decision
Solution extraite
The appeal was admissible because no cantonal appeal route was available against the decision to strike the case from the docket, including its costs and expenses ruling.
Motifs extraits
Under cantonal law only certain interlocutory rulings of the instructing judge could be appealed internally; a docket-striking decision was not among them, so the federal remedy was open.
