Question juridique clé
Whether the appeal against the cantonal remand decision was admissible under Article 93 BGG.
Solution extraite
The remand decision was an independently appealable interlocutory decision because it caused a non-reparable disadvantage by making the finding of adequate causation binding.
Motifs extraits
The cantonal ruling contained materially binding findings on adequate causation; if left unchallenged, the later final decision could practically no longer correct that result.
