Question juridique clé
Whether the Zurich and Schwyz tax assessments created an unconstitutional inter-cantonal double taxation conflict.
Solution extraite
No double taxation was shown; the appellants did not sufficiently demonstrate any collision rule violation, and Zurich had not taxed the same taxable object for the same period in a way requiring relief.
Motifs extraits
The Court found no current or virtual double taxation. Zurich had either not assessed or had finalized earlier assessments, and the appellants failed to substantiate a competing tax claim for the same object and period.
