Decisione estratta
The appeal had become moot because the respondent annulled the challenged decision and replaced it with a new decision on the same subject.
Motivazione estratta
Under Art. 83 LPA-VD, the authority may replace its decision during the proceedings. Since the original decision was fully annulled before the end of the investigation, the appeal no longer had an object.
