Kernrechtsfrage
Whether Zurich had standing to appeal to the Federal Supreme Court
Extrahierter Entscheid
Yes. Zurich was directly affected by the reimbursement order and had participated below, so it was entitled to appeal under Art. 89 para. 1 BGG.
Extrahierte Begründung
The repeal of the former ZUG appeal provision did not remove standing. As a canton cannot act sovereignly against another canton, direct financial burden and participation below suffice.
