Question juridique clé
Whether the airport cooperative had to bear administrative procedure costs despite not filing its own requests in the appeal proceedings.
Solution extraite
Yes. As the original applicant and main party in the planning-approval procedure, it remained a party in the appeal on the merits and could be charged costs when the approval was annulled.
Motifs extraits
Cost allocation under Art. 63(1) VwVG depends on who loses the case, not on whether the party filed independent requests. Remaining silent did not remove the cooperative's party status or cost risk.
