Kernrechtsfrage
Whether the main request for full withholding-tax exemption was admissible within the scope of the appeal
Extrahierter Entscheid
The request went beyond the dispute before the tax authority and the Federal Administrative Court, so the Federal Court could not examine it to that extent.
Extrahierte Begründung
The subject matter was limited to the admissibility of the notification procedure; a direct source exemption and broader abuse review would expand the dispute.
