Kernrechtsfrage
Whether the appeal could seek a declaratory finding of undue delay after the complained-of delay had ended.
Extrahierter Entscheid
No current and practical interest existed; the requested declaration was inadmissible.
Extrahierte Begründung
A declaratory request requires a protected interest. Once the new IV decision had been issued and the cantonal court had already noted the excessive length of the prior delay and warned the authority, the matter lacked the exceptional circumstances that would justify dispensing with present interest.
