Kernrechtsfrage
Whether the appellant qualified as a tax-exempt descendant under § 142(3) StG/AG despite lacking legal filiation to the deceased.
Extrahierter Entscheid
No. The canton may rely on civil-law kinship; since the appellant remained legally the child of her mother's husband, she was not a descendant of the deceased for inheritance-tax purposes.
Extrahierte Begründung
The cantonal statute is construed in line with civil law. Because the paternity presumption was not timely challenged, no legal parent-child relationship existed between the appellant and the deceased, and treating her as a more remote taxable person was not arbitrary.
