Question juridique clé
Whether Luzern's tax on Schreiber's movable assets constituted prohibited inter-cantonal double taxation.
Solution extraite
No double taxation was shown because Schwyz taxed only the land and the Rigi hotel business, while Luzern taxed only other movable assets outside that business fund.
Motifs extraits
Double taxation exists only if two cantons claim tax sovereignty over the same subject and object for the same period. The record did not show that Schwyz asserted tax power over the movable assets taxed by Luzern.
