Kernrechtsfrage
Whether the appeal against the cantonal judgment on access to the file was admissible under Art. 93 LTF
Extrahierter Entscheid
The appeal was inadmissible because the appellant did not show irreparable legal harm, and no exception under Art. 93 para. 1 LTF was met.
Extrahierte Begründung
The challenged ruling was incidental in nature; material limits on access to the file can be reviewed together with the final decision. The appellant did not establish a legal prejudice that could not later be remedied, nor that immediate admission would avoid lengthy and costly evidence proceedings.
