Key legal question
Whether the interlocutory procedural order in the sealing proceedings was immediately appealable under Art. 93(1)(a) BGG due to irreparable harm.
Extracted holding
The appellants failed to show any irreparable legal disadvantage; the order merely granted them optional participation rights and did not decide the unsealing issue.
Extracted reasoning
Interlocutory procedural orders in sealing proceedings are generally not immediately appealable. The challenged order did not impose a detriment but allowed the bank to receive the request and comment. Any complaint about the merits of unsealing can be raised later against the final unsealing decision.
