Kernrechtsfrage
Whether the interlocutory decision on access to the file was separately appealable by administrative law appeal
Extrahierter Entscheid
The interlocutory decision could not be separately challenged because no irreparable disadvantage was shown; any violation of the right to be heard could still be reviewed against the final decision.
Extrahierte Begründung
Immediate appeal against file-access rulings is exceptional. Mere prolongation of proceedings is insufficient, and the case did not involve such an especially burdensome procedure that would have to be repeated for reasons of procedural economy.
