Whether the appeal became moot after the compensation fund reconsidered and replaced the challenged decision.
The dispute had become moot because the new decision granted the appellant's requested relief and replaced the challenged decision.
Under Art. 53(3) LPGA, the insurer may reconsider an appealed decision before sending its response. Here the fund used that power within the response period, acknowledged that the contributions were deemed paid, and stated that a new decision would annul and replace the challenged one.
