Key legal question
Where is the taxpayer's fiscal domicile for 2011?
Extracted holding
Her principal fiscal domicile is in Lausanne, not Delémont.
Extracted reasoning
As an adult single person working full-time near Lausanne and renting her own flat there, a presumption arose that her center of interests was at the workplace. Her family and social ties in Delémont were not sufficiently strong to rebut that presumption.
