Questione giuridica chiave
Whether the cantons' different tax bases caused current intercantonal double taxation under Art. 127(3) BV.
Decisione estratta
Yes as to Fribourg's assessment method; no as to Zurich's. The court held that the total quoted taxable base exceeded 100%, creating current double taxation.
Motivazione estratta
Fribourg wrongly reduced the taxable base by taking the loss of the second partnership into account, while Zurich taxed the first partnership's full profit. Only the profit of A.________ & Co had to be allocated object-wise; the loss of B.________ & Co could not be shifted to the other special tax domicile.
