Question juridique clé
Whether the cantonal appeal against the IV decision of 6 May 2010 was filed within time.
Solution extraite
The appeal period started only when counsel received the corrected service on 9 June 2010, so the appeal filed on 8 July 2010 was timely.
Motifs extraits
Service was defective because the decision had been addressed to the insured person despite representation. Counsel's prior knowledge of the decision's existence and tenor did not replace proper service, since the decisive point is access to the actual reasoning and text of the decision. The authority bears the burden of proving service; the cantonal court wrongly inferred earlier receipt from the mandate wording.
