Question juridique clé
Whether the appeal against an incidental decision refusing to allow new allegations was admissible without showing irreparable harm.
Solution extraite
The appellant did not demonstrate a non-theoretical risk of irreparable harm; the appeal was therefore inadmissible.
Motifs extraits
Under Art. 93(1)(a) LTF, an incidental decision is appealable only if it may cause irreparable harm. The asserted risk that documents might be destroyed later was speculative and conflated loss of evidence with the ability to introduce new facts.
