Whether the appeal became moot after the invalidity insurance office partially reconsidered its opposition decision.

The dispute had become moot because the office's revised decision granted the requested relief.
Motifs extraits
Under Art. 53(3) LPGA, the insurer may reconsider its decision before sending its observations to the appellate authority. The office exercised this power and issued a new decision that satisfied the appellant's conclusions, so the case had no remaining object and had to be struck from the docket.
