Whether the appeal against the original daily allowance decisions remained live after rectifying decisions were issued.
The appeal became moot because the challenged decisions were replaced by corrective decisions that essentially granted the subsidary relief sought.
Under Art. 53 para. 3 LPGA and Art. 83 LPA-VD, the authority may reconsider the decision until its response is filed; once the contested decisions were replaced and the appellant obtained the requested increase, the case lost its object.
