Key legal question
Whether the constitutional complaint was admissible against the final cantonal tax assessment and the requested relief beyond annulment could be sought.
Extracted holding
The complaint was admissible only as a constitutional complaint against the final tax assessment, and the request for relief beyond annulment was inadmissible because the remedy is generally cassatory.
Extracted reasoning
The cantonal final assessment together with the definitive tax bill is a public-law act reviewable by constitutional complaint; however, the federal remedy is limited to annulment absent an exception.
