Question juridique clé
Whether the administrative-law appeal against the closure decision was admissible and whether the appellant had standing.
Solution extraite
The appeal was admissible in principle, and the appellant had standing because he had been questioned as an accused and the statement also concerned his own activities.
Motifs extraits
In mutual assistance, the closure decision is generally appealable. The challenged measure allowed consultation of only one specific document, so proportionality could already be reviewed. Standing was recognized because the appellant was a party to the administrative criminal proceeding and, alternatively, a witness may complain where the deposition concerns personal information.
