Kernrechtsfrage
Admissibility of the public-law complaint against the cantonal tax domicile ruling
Extrahierter Entscheid
The complaint was admissible in principle against Aargau; claims extending beyond the dispute, including compensation for extraordinary costs and interest on alleged overpaid taxes in relation to Zurich, were inadmissible.
Extrahierte Begründung
A final cantonal decision on tax liability may be challenged by public-law complaint. However, relief outside the tax-domicile dispute and interest claims based solely on cantonal law fall outside the scope of the double-taxation complaint.
