Question juridique clé
Whether the cantonal judgment was an appealable final or partial decision, or an incident decision requiring special conditions under Art. 93 LTF.
Solution extraite
The judgment was not a partial decision; it was an incident decision because it remanded the matter for further examination, and neither irreparable harm nor the conditions for immediate review were shown.
Motifs extraits
The cantonal court decided only one disputed element of the calculation and not the supplementary-benefit entitlement as such. A remand for further instruction normally causes no irreparable harm and does not justify immediate federal review.
