Kernrechtsfrage
Whether the appellant could obtain access to the file of the concluded mutual legal assistance proceeding PR01.010143-JTR.
Extrahierter Entscheid
He had no enforceable right to inspect the closed assistance file; any entitlement had lapsed after the closing decision became final.
Extrahierte Begründung
As the account holder he could in principle have participated earlier, but after final closure he could no longer claim notification or file access. The access request could not reopen final decisions, and any remaining interest was insufficient.
