Question juridique clé
Whether CSS could recover accident benefits from Zurich as the allegedly responsible insurer.
Solution extraite
CSS had no enforceable reimbursement claim against Zurich for the accident benefits paid to P. on 15 February 2000.
Motifs extraits
A reimbursement claim between social insurers requires a valid ground to revoke the original benefits decision, via revision or reconsideration. Even assuming new facts existed, CSS learned of them in February 2001 but took no timely action within the one-year period; the claim was therefore time-barred.
