Key legal question
Whether the federal appeal was admissible against the cantonal judgment and earlier cantonal decisions
Extracted holding
The appeal was admissible only against the latest cantonal judgment; challenges to the earlier decisions were inadmissible due to the devolutive effect, and the subsidiary constitutional complaint was unavailable.
Extracted reasoning
A cantonal last-instance public-law tax domicile decision falls under the federal public-law appeal. Earlier cantonal decisions are replaced by the final judgment, and a subsidiary constitutional complaint is excluded where the ordinary appeal is open.
