Questão jurídica principal
Whether the tax security demand under Art. 169 LIFD was admissible before the underlying tax assessment became final.
Decisão extraída
Yes. Securities may be required before the tax is fixed by a final decision if the tax claim appears plausible.
Fundamentação extraída
The statute expressly allows security before final assessment; the court reviews only prima facie whether the tax claim and amount are credible.
