Kernrechtsfrage
Whether the appeal against the interlocutory order was admissible under Art. 93 BGG despite the partial denial of file access.
Extrahierter Entscheid
The order could not be challenged because no irreparable legal harm was shown; the denial of access can be raised later against the final judgment as a violation of the right to be heard.
Extrahierte Begründung
A restrictive interlocutory ruling on inspection of files normally has no irreparable effect. The company could assert any hearing violation in an appeal against the final decision, which could lead to remittal and renewed decision after full access and comment.
