In particular it may be stated that whereas under the old section 144 the power to take action in urgent cases of nuisance or apprehended danger to public tranquility had been conferred on "a District Magistrate, a Chief Presidency Magistrate, a sub Divisional Magistrate or any other Magistrate, specially empowered by the State Government", under the present section 144 the power has been conferred on "a District Magistrate, Sub Divisional Magistrate or any other Executive Magistrate specially empowered by the State Government in that behalf." Having regard to such implementation of the concept of separation of judicial functions from executive or administrative functions and allocation of the former to the Judicial Magistrates and the latter to the Executive Magistrates under the Code of 1973, it will be difficult to accept the contention of the counsel for respondents 5 and 6 that the order passed by a District Magistrate, Sub Divisional Magistrate or any other Executive Magistrate under the present section 144 is a judicial order or quasi judicial order, the function thereunder being essential an executive (police) function.
