Key legal question
Whether the appeal against the cantonal judgment on access to the file was admissible under Art. 93 LTF
Extracted holding
The appeal was inadmissible because the appellant did not show irreparable legal harm, and no exception under Art. 93 para. 1 LTF was met.
Extracted reasoning
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.
