JUDGMENT

1. Leave granted.

2. We have heard learned counsel on both sides.

3. The respondent was appointed in the Rajasthan State Police Service. He was put in the select list on December 28,1987. The Union Public Service Commission had approved it on February 2, 1988. He was due to retire on May 31, 1988 on attaining superannuation. His name along with eight other candidates, was included for allotment from the State quota to the Indian Police Service. The requirements of the Indian Police Service (Appointment by Promotion) Regulations, 1955 (for short, the "Promotion Regulation") envisage that the Union Public Service Commission, under Regulation 7, shall consider the list prepared by the Committee along with other documents received from the State Government and, unless it considers any change necessary, it shall approve the list. Sub-regulation (4) is relevant in this case which provides that the select list shall ordinarily be in force until its review and revision effected under sub-regulation (4) or (5) is approved under sub-regulation (I) or, as the case may be, is finally approved under sub-regulation (2). As per regulation 7(3), the list as finally approved by the UPSC shall form the .select list. Proviso thereto indicates thus:

"Provided further that in the event of grave lapse in the conduct or performance of duties on the part of any member of the State Police Service included in the Select List, a special review of the select list may be made at a lime at the instance of the State Government and the Commission may, if it so thinks fit, remove the name of such member of the State Police Service from the Select List."

4. Regulation 9 of the Promotion Regulations, deals with appointment of State Police Service officers to Indian Police Service. Sub-regulation (2) thereof reads as under:

"It shall not ordinarily he necessary to consult the Commission before such appointments are made, unless during the period intervening between the inclusion of the name of a member of the State Police Service in the Select List and the date of the proposed appointment there occurs any deterioration in the work of the member of the State Police Service or there is any other ground which, in the opinion of the State Government or the Central Government, is such as to render him unsuitable for appointment to the service."

5. While making recommendation, the State Government is required to furnish in this regard the "no deterioration certificate" of the selected candidates as per the letter No. 11/4173-AIS(I) dated May 22, 1973 of the Union of India, Administrative Reforms of the Department of Personnel which has been made pan of the Promotion Regulations as decision No.9 which reads as under:

"Having regard to the provision contained in the proviso to the sub-regulation (4) of regulation 7 of IAS (Appointed by Promotion) Regulations, 1955, the State Government/Joint Cadre Authority, while making recommendations for the appointment of a member of State Civil Service to Indian Administrative Service, may forward a certificate on the following lines:

"The State Government the Joint Cadre Authority certifies that subsequent to the inclusion of the name of Shri ----- in the Select List, there has been no deterioration in his work as to render him unsuitable for appointment to the Indian Administrative Service nor has any lapse in his conduct or performance of duties in his part come to the notice of the State Government/ the Joint Cadre Authority."

6. This requirement is mandatory for the reason that before appointment of the persons to the Indian Police Service, under the Promotion Regulations, the Union Government should receive the certificate from the concerned State Government or the Union Territory that there has been no deterioration in the service of the incumbent in the interregnums as it is mandatory to know the continued quality, integrity, honsety and efficiency of the concerned officer.
