Question juridique clé
Whether the appeal remained live after the authority replaced the challenged decision with new decisions.
Solution extraite
The appeal had become moot because the challenged opposition decision was fully cancelled and replaced by new decisions on the same subject matter.
Motifs extraits
Under Art. 83 LPA-VD, the authority may replace its decision during proceedings; once it did so, the challenged decision no longer existed, so the appeal no longer had an object.
