Whether the appeal became moot after the respondent reconsidered its challenged decision under Art. 53(3) LPGA.
Yes. The respondent retracted the contested decision and announced a new lawful decision, so the dispute on the merits was moot.
Under Art. 53(3) LPGA, an insurer may reconsider a challenged decision before sending its response. Because the authority itself admitted the decision was manifestly incorrect, reconsideration was appropriate and the substantive dispute no longer had an object.
