Questão jurídica principal
Whether the insurer could reconsider its opposition decision during the pending appeal and thereby deprive the appeal of purpose.
Decisão extraída
Yes. The insurer reconsidered and annulled the contested decision before its response to the appeal, so the appeal became without object.
Fundamentação extraída
Under Art. 53 para. 3 LPGA, a social insurer may reconsider a decision or opposition decision until it has sent its response to the reviewing court. Because the insurer annulled the challenged decision to complete the investigation, there was no remaining live dispute.
