Whether the first-instance pronouncement had to be annulled ex officio because it addressed the wrong matter.
Yes. The decision was erroneous because it refused appointed counsel although the appellant already had such counsel; it was therefore annulled ex officio.
The challenged pronouncement did not decide the request for replacement of appointed counsel, but mistakenly denied assistance already in place. The appellate court could not rely on the later corrective letter because it postdated the appeal.
