Whether the appeal became moot after the insurer reconsidered the challenged decision and resumed instruction.
Yes. The insurer's pendente lite reconsideration fully satisfied the subsidiary request for annulment and referral, so the case had become moot and had to be removed from the docket.
Under Art. 53(3) LPGA, an insurer may reconsider a decision while an appeal is pending; if it grants the appellant's conclusions, the appeal becomes moot. Here, the CNA reopened the file, which de facto annulled the contested opposition decision.
