Question juridique clé
Whether Solothurn could tax the undivided inheritance for 2002-2003 despite uncertainty about heirs and shares.
Solution extraite
No. Under cantonal law, the undivided inheritance was taxable at the deceased's last domicile; Solothurn therefore had no taxing power while uncertainty persisted.
Motifs extraits
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.
