Key legal question
Whether the appellant's tax domicile for 1 June 2000 to 31 December 2002 was in Zurich or Schwyz under the ban on intercantonal double taxation.
Extracted holding
The appellant failed to prove a genuine move of his centre of life to Schwyz; Zurich retained the tax domicile for the relevant period.
Extracted reasoning
The objective circumstances did not show stronger personal or social ties to Schwyz. The Schwyz apartment was a mere sham domicile, while the long-standing domicile in Zurich remained decisive.
