Question juridique clé
Whether the cantonal court could refuse to consider new facts and evidence after a remand decision had already finally resolved the disputed points.
Solution extraite
It was not arbitrary to hold that Art. 19 VRP does not reopen issues definitively settled by a final remand decision; new allegations on those points could be excluded.
Motifs extraits
The court interpreted 'until the end of the proceedings' in Art. 19 VRP in light of the binding effect of remand decisions, consistent with procedural economy and legal certainty.
