Questão jurídica principal
Whether the request to annul the Lucerne tax administration decision and post-deadline supplements were admissible
Decisão extraída
The request against the earlier Lucerne decision was inadmissible because it had been replaced by the cantonal court judgment, and the late supplements were disregarded.
Fundamentação extraída
Only the final cantonal judgment could be challenged; unsolicited submissions after the appeal period had no effect.
