Question juridique clé
Whether the cantonal decision was appealable as a final decision despite a remand for calculation of the pension amount.
Solution extraite
The decision was appealable because the main issue was conclusively decided; the remand concerned only implementation. Even as an interim decision, it was challengeable due to irreparable harm.
Motifs extraits
The lower court had definitively ruled on entitlement to a half pension from 1 February 2006, leaving only arithmetic implementation.
