What is Doctrine of Merger?

The juristic justification of the doctrine of merger may be sought in the principle that there cannot be, at one and the same time. more than one operative order governing the same subject-matter. Therefore the judgment of an inferior court, if subjected to an examination by the superior court, ceases to have existence in the eye of law and is treated as being superseded by the judgment of the superior court. In other words, the judgment of the inferior court loses its identity by its merger with the judgment of the superior court.

The logic underlying the doctrine of merger is that there cannot be more than one decree or operative orders governing the same subject-matter at a given point of time. When a decree or order passed by an inferior court, tribunal or authority was subjected to a remedy available under the law before a superior forum then, though the decree or order under challenge continues to be effective and binding, nevertheless its finality is put in jeopardy. Once the superior court has disposed of the lis before it either way- whether the decree or order under appeal is set aside or modified or simply confirmed, it is the decree or order of the superior court, tribunal or authority which is the final, binding and operative decree or order wherein merges the decree or order passed by the court, tribunal or the authority below. However, the doctrine is not of universal or unlimited application. The nature of jurisdiction exercised by the superior forum and the content or subject-matter of challenge laid or which could have been laid shall have to be kept in view.
