Whether the appeal remained justiciable after the insurer issued a reconsideration decision during the appeal
The reconsideration decision annulled and replaced the challenged opposition decision, so the appeal became moot and had to be struck from the roll.
Under Art. 53(3) LPGA, the insurer may reconsider a contested opposition decision until it has filed its response. Since it did so in time, the original decision ceased to exist as an object of appeal.
