5. The matter has been contested by the respondents by filing a counter-affidavit on their behalf. Learned State counsel, by referring to the averments made in the aforesaid counter-affidavit, submits that very entry of the petitioners in service by order dated 24.10.1987 (Annexure-3) was illegal and void, as the Special Land Acquisition Officer, Medium Irrigation Scheme, Dumka was not empowered to make such appointment. It is contended that originally all the Special Land Acquisition Officers were empowered to make such appointment by Government letter dated 18.02.1978, but it was subsequently withdrawn by Government letter dated 02.12.1983 itself, yet the appointment of the petitioners on the post of Mapak/ Amin was made by order 24.10.1987 (Annexure-3), when the Special Land Acquisition Officer was not authorized to make such appointment. According to him, since the initial appointment of the petitioners itself was illegal, therefore, any subsequent extension of their services would not legalize the same. It is further pointed out that neither any advertisement was issued for making such appointment nor the rules of reservation was followed. Hence, the appointment of the petitioners was in the teeth of Articles 14 and 16 of the Constitution of India. It is also pointed out that since large number of illegal appointments were made by certain officers of the department, therefore, the Vigilance Department of the Government lodged an F.I.R. against those officers giving rise to Vigilance P.S. Case No. 4 of 1997 (Annexure-A to the counter-affidavit), in which the names of the petitioners in the list of the employees, illegally appointed by unauthorized officers of the department have been mentioned. It was further submitted that in view of the principles enunciated by a constitution Bench of the Hon’ble Apex Court in the Case of Secretary, State of Karnataka and others. V.
