Questão jurídica principal
Whether the taxpayer's new documents could be admitted before the Federal Court
Decisão extraída
The new documents were inadmissible because they could and should have been produced in the cantonal proceedings and were not prompted by any unforeseeable reasoning in the appealed judgment.
Fundamentação extraída
Art. 99(1) LTF allows new facts and evidence only when the lower judgment itself gives rise to them; that was not the case here.
