Key legal question
Whether the appeal was admissible against the cantonal decision and whether the request to annul the assessment and seek a declaratory ruling was admissible.
Extracted holding
The appeal was admissible in principle, but the request to annul the assessment was inadmissible because the assessment was already covered by the devolutive effect; the declaratory request failed for lack of a legal interest.
Extracted reasoning
The challenged cantonal decision was final for federal tax purposes, but a declaratory judgment is unavailable where a performance decision exists. The assessment is deemed challenged together with the lower decision.
