Key legal question
Whether the missed objection deadline should be restored for the deceased taxpayer and his heirs.
Extracted holding
The taxpayer's severe terminal cancer constituted a sufficient hindering cause; the heirs filed the objection within 30 days after the obstacle ceased with his death, so the deadline was restored.
Extracted reasoning
A serious illness need not amount to total incapacity; here the terminal cancer and complete work incapacity justified excusing the delay. The heirs succeeded because the statutory 30-day period ran from the death, when the hindrance ended.
