Question juridique clé
Whether the public-law appeal was admissible despite the lack of current practical interest.
Solution extraite
The appeal was inadmissible because the appellant no longer had a current practical interest and did not show a sufficiently important public interest exception.
Motifs extraits
The VAT had already been reimbursed before the federal appeal was filed; absent a present practical interest, and without substantiation of the exception for recurring issues escaping timely review, the Court would not examine the merits.
