Key legal question
Which canton had the exclusive right to tax the 2001 independent income of A.X. under the ban on intercantonal double taxation?
Extracted holding
Geneva had the exclusive taxing right because the activity was carried out entirely from Geneva and no business activity took place in Fribourg in 2001.
Extracted reasoning
The taxpayers were domiciled in Geneva; the independent activity was performed exclusively from Geneva premises. The Fribourg assessment therefore conflicted with Art. 127(3) Cst.
