Question juridique clé
Whether the appellant's fiscal domicile for 2004 was in Bern or Jura under the intercantonal double taxation ban.
Solution extraite
The appellant did not rebut the presumption that his fiscal domicile was at his workplace; it was in the canton of Bern in 2004.
Motifs extraits
As a single dependent employee with his own apartment in Bern, long residence there, economic autonomy, and only limited family/social ties in Jura, his weekly returns to his parents' home were insufficient to shift domicile to Jura.
