Kernrechtsfrage
Whether the taxpayer could seek a declaratory ruling on commuter status separately from the withholding-tax request.
Extrahierter Entscheid
A separate declaratory request was inadmissible because the protected interest was already covered by the claim to uphold withholding taxation.
Extrahierte Begründung
A declaratory interest is lacking where the same legal protection can be obtained through the performance claim.
