Questione giuridica chiave
Whether Solothurn could tax the undivided inheritance for 2002-2003 despite uncertainty about heirs and shares.
Decisione estratta
No. Under cantonal law, the undivided inheritance was taxable at the deceased's last domicile; Solothurn therefore had no taxing power while uncertainty persisted.
Motivazione estratta
Because the heirs and their shares were still unclear, § 15 Abs. 2 StG assigned taxation to the canton of the testator's last residence, here Basel-Stadt.
