Whether the appeal had become moot after the AI office issued a new decision replacing the challenged decision.
The appeal case had become moot because the challenged decision was annulled and replaced by a new decision, which was separately appealed in another file.
Under Art. 53(3) LPGA, the insurer may reconsider a decision already under appeal until its response is sent to the reviewing court. The AI office exercised that power, so there was no longer a live dispute in this file.
