Question juridique clé
Whether the appeal against the refusal to order a supplementary expert report was admissible
Solution extraite
The appeal was inadmissible because the challenged ruling was an incidental decision and the appellant failed to show irreparable legal harm under Article 93(1)(a) LTF; Article 93(1)(b) LTF was also inapplicable.
Motifs extraits
The refusal of evidence at the investigation stage can still be challenged later against the final decision, so no irreparable legal prejudice is caused. The case did not allow immediate final resolution that would avoid lengthy and costly evidence proceedings.
