Question juridique clé
Whether the Aargau assessment created prohibited intercantonal double taxation for the usufruct property share.
Solution extraite
Yes. The same movable usufruct property could not be taxed in Aargau, because movable usufruct property is taxable at the usufructuary's domicile.
Motifs extraits
For usufruct arrangements, formal identity of the taxpayer is not required. The decisive point is that the same property may not be taxed twice; the taxable period was also identical in both cantons.
