Question juridique clé
Admissibility of the appeal against an interim decision restricting participation rights and file access
Solution extraite
The appeal was inadmissible insofar as it relied on participation rights and costs, because no irreparable legal disadvantage was shown.
Motifs extraits
A mere postponement of participation in evidence-taking normally does not cause irreparable harm. The appellants did not substantiate a formal denial of justice either.
