Questão jurídica principal
Whether the appeal against the incidental mutual legal assistance order was admissible despite the lack of final closing decision.
Decisão extraída
The appeal was admissible because the appellants sufficiently showed an immediate and irreparable harm stemming from the challenged clause on early use of information.
Fundamentação extraída
Under the Mutual Assistance Act, incidental decisions are separately appealable only if they cause such harm; the appellants explained that clause 5 allowed premature use of information and thus a non-repairable infringement.
