Doctrine of Merger:
(i) Where an appeal or revision is provided against an order passed by a court, tribunal or any other authority before superior forum and such superior forum modifies, reverses or affirms the decision put in issue before it, the decision by the subordinate forum merges in the decision by the superior forum and it is the latter which subsists, remains operative and is capable of enforcement in the eye of law.
(ii) The jurisdiction conferred by Article 136 of the Constitution is divisible into two stages. The first stage is upto the disposal of prayer for special leave to file an appeal. The second stage commences if and when the leave to appeal is granted and the special leave petition is converted into an appeal.
