Questão jurídica principal
Whether the appeal became moot after the compensation office issued a new decision replacing the challenged one.
Decisão extraída
Yes. The office reconsidered the challenged decision within the response period and issued a new decision that replaced it, so the appeal had no subject matter remaining.
Fundamentação extraída
Under Art. 53(3) LPGA, the insurer may reconsider a decision against which an appeal was filed until sending its response to the appellate authority. Because the new decision annulled and replaced the contested one and covered the disputed period, the court had only to take note that the case was moot.
