Whether the appeal became moot after the insurer's reconsideration decision of 2014-11-26
Yes. By fully granting the appellant's requested relief through reconsideration and annulling the challenged decision, the appeal lost its object.
Under Art. 53(3) LPGA, an insurer may reconsider a contested decision before sending its observations to the appellate authority. If reconsideration entirely satisfies the appeal, the proceedings become moot and the case must be struck from the docket.
