Questão jurídica principal
Whether the appeal became moot after the respondent withdrew the challenged decision and said a new decision would follow.
Decisão extraída
Yes. Once the challenged decision was withdrawn, the appeal no longer had an object and the case had to be struck from the roll.
Fundamentação extraída
The respondent acknowledged that the economic investigation had to be reopened and withdrew its decision; the challenged decision was therefore annulled and the dispute became moot.
