Questione giuridica chiave
Whether the assessment was invalid because the Amtschreiberei opened it without prior approval by the tax administration.
Decisione estratta
The procedural defect was cured because X. timely appealed to the competent tax administration, which then issued the objection decision itself.
Motivazione estratta
The Amtschreiberei may only open the assessment, while the tax administration remains the deciding authority. The lack of prior approval made the opening defective, but no disadvantage resulted and the competent authority could cure the defect on objection.
