Question juridique clé
Whether the insurer could revise its opposition decision while the appeal was pending and thereby eliminate the dispute.
Solution extraite
The insurer validly reconsidered and annulled the challenged decision by issuing a new decision that granted the disputed supplementary benefits.
Motifs extraits
Under Art. 53 para. 3 LPGA, the insurer may reconsider a decision that is under appeal until it has sent its response to the appellate authority. That condition was met, so the court took note of the revised decision and found the case moot.
