Question juridique clé
Whether the appeal against the incidental mutual assistance order was admissible despite lack of immediate and irreparable harm being argued by the MPC.
Solution extraite
The appellant sufficiently showed a non-reparable prejudice linked to the challenged guarantee clause, so the appeal was admissible.
Motifs extraits
The Court held that incidental mutual assistance orders are not automatically harmful; the affected person must show why the measure causes irreparable prejudice. That threshold was met because clause 5 allegedly allowed premature use of information in violation of mutual assistance rules.
