Key legal question
Whether the appeal against the seizure order was admissible without showing immediate and irreparable harm.
Extracted holding
No. A challenge to an incidental seizure order in mutual assistance is admissible only exceptionally, and the appellants did not substantiate any immediate and irreparable prejudice.
Extracted reasoning
The appellants failed to show concrete consequences such as imminent contractual defaults or enforcement measures; therefore the seizure order could not be attacked at this stage.
