In All India Judges’ Assn. v. Union of India, (2002) 4 SCC 247; wherein the Supreme Court observed;
“31- As we have already mentioned, the Shetty Commission had recommended that the Chief Metropolitan Magistrates should be in the cadre of District Judges. In our opinion, this is neither proper nor practical. The appeals from orders passed by the Chief Metropolitan Magistrates under the provisions of the Code of Criminal Procedure are required to be heard by the Additional Sessions Judge or the Sessions Judge. If both the Additional Sessions Judge and the Chief Metropolitan Magistrate belong to the same cadre, it will be paradoxical that any appeal from one officer in the cadre should go to another officer in the same cadre. If they belong to the same cadre, as recommended by the Shetty Commission, then it would be possible that the junior officer would be acting as an Additional Sessions Judge while a senior may be holding the post of the Chief Metropolitan Magistrate. It cannot be that against the orders passed by the senior officer it is the junior officer who hears the appeal.
There is no reason given by the Shetty Commission as to why the post of the Chief Metropolitan Magistrate be manned by the District Judge, especially when as far as the posts of the Chief Judicial Magistrates are concerned, whose duties are on a par with those of the Chief Metropolitan Magistrate, the Shetty Commission has recommended, and in our opinion rightly, that they should be filled from amongst Civil Judges (Senior Division). Considering the nature and duties of the Chief Judicial Magistrates and the Chief Metropolitan Magistrates, the only difference being their location, the posts of Chief Judicial Magistrate and Chief Metropolitan Magistrate have to be equated and they have to be placed in the cadre of Civil Judge (Senior Division). We order accordingly.”
