Kernrechtsfrage
Whether the appellant suffered prohibited intercantonal double taxation for 2002.
Extrahierter Entscheid
Yes. Thurgau had already fixed the tax domicile in Weinfelden, but Vaud also subjected him to unlimited taxation for the same period.
Extrahierte Begründung
A current double taxation exists when two cantons tax the same person for the same object and period. Here both cantons claimed unlimited tax liability for 2002.
