Questão jurídica principal
Whether the cantonal appeal was rightly declared inadmissible for failure to pay the advance on time despite the appellant's absence abroad.
Decisão extraída
Yes. The appellant had planned his absence, had his mail forwarded, and should have instructed his son; the omission was attributable to him and did not justify restoration of the deadline.
Fundamentação extraída
Under the direct federal tax rules, a non-fault impediment requires objective or excusable subjective impossibility. A foreseeable absence abroad does not excuse failure to manage incoming court mail and payment of the advance within the set deadline.
