Question juridique clé
Whether the cantonal court could enter into the new complaint against the IV office's implementing decision of 24 May 2007.
Solution extraite
The complaint raised issues already finally decided by the remand judgment of 31 October 2006; only the recalculation of the back-payment remained open.
Motifs extraits
The earlier remand judgment was final because it had not been appealed. Its binding reasoning covered the entitlement to third-party payment and the proportional split of the back-payment. The new complaint attacked those settled points rather than the limited issue left open.
