Questão jurídica principal
Whether the appellant could contest the finalized ex officio tax assessment when only her share of the outstanding tax was being fixed.
Decisão extraída
No. The final 2002 ex officio assessment could not be reopened; only the calculation of the appellant’s share of the remaining tax was reviewable.
Fundamentação extraída
Under cantonal law, mirroring the federal system, separation of spouses allows a separate decision on each spouse’s share of the global tax, while the original tax assessment remains final. Article 138 LF was irrelevant.
