Questão jurídica principal
Whether the complaint against retroactive deletion from the VAT register and repayment of input tax is admissible.
Decisão extraída
The complaint was admissible only as to the substantive VAT issues; the request concerning reimbursement of wrongly invoiced and paid VAT was inadmissible because it was not yet part of the dispute.
Fundamentação extraída
Only decisions on substantive VAT rules were challengeable under the Liechtenstein-Switzerland VAT agreement; the reimbursement issue had not yet been decided below.
