Question juridique clé
Whether the appeal against the seizure order was admissible without showing immediate and irreparable harm.
Solution extraite
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.
Motifs extraits
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.
