Key legal question
Whether the appeal against the refusal of unrestricted access to the file was admissible as a challenge to a final decision or an independent appealable interim order.
Extracted holding
The challenged restriction was an interim procedural order, not a final mutual-legal-assistance decision, and it was not separately appealable.
Extracted reasoning
Only interim orders causing an immediate and irreparable disadvantage through seizure of assets or the presence of persons participating in the foreign proceedings are separately appealable. The complained-of restriction concerned neither of those situations.
