Whether the respondent's reconsideration of the contested opposition decision rendered the appeal moot
Yes. By withdrawing the challenged decision and fully accepting the appellant's claims, the dispute became moot.
Under Art. 53(3) LPGA, the insurer may reconsider a decision against which an appeal has been filed. Since the respondent retracted the decision and acknowledged that the sanction lacked justification, the appeal no longer had a live object.
