JUDGMENT

CHINNAPPA REDDY, J. :— Special leave granted.

2. The petitioner belongs to the Scheduled Castes. He joined the Delhi Police as a Constable on May 18, 1979. He became a Graduate in 1981. On October 10, 1981, the Staff Selection Committee invited applications for filling up vacancies of posts of Sub-Inspectors of Police on the basis of a competitive examination. There were altogether 170 vacancies. The break up of the vacancies, General and Reserved, Departmental and Non-departmental, as admitted by the respondents was as follows:-

"Non-departmental Departmental Total

i) General 98 12 110

ii) Scheduled Caste 22 3 25

iii) Scheduled Tribe (including 5 C.F.) 16 2 18

iv) Ex-servicemen 17 - 17

153 17 170"

The petitioner who appeared at the competitive examination was selected for appointment against one of the three vacancies reserved for Scheduled Castes from Departmental candidates. He was, however, not appointed on the ground that under the Rules as interpreted by the Delhi High Court in Raj Kumar Singh v. Union of India, there could be no further reservation for candidates belonging to the Scheduled Castes in the quota available to departmental candidates. A writ petition filed by the petitioner was dismissed by a Division Bench, who considered themselves bound by the decision in Raj Kumar Singh v. Union of India (supra). Hence the appeal by special leave.

3. Rule 7 of the Delhi Police Rules is as follows :

"Recruitment of S.I. (Executive) - Fifty per cent of the vacancies in the rank of S.I. and executives shall be filled by direct recruitment and 50% of the vacancies by way of promotion. Out of 50% direct quota 10% of the posts shall be filled through the deptt. candidates viz. the constables, head constables and the A.S.I. of not more than 30 years of age having the requisite qualifications and standards through the examinations for the departmental candidates by the SSC in accordance with relevant rules,"

"Eduction, Physical and other standards for the posts of Sub-Inspector (direct recruited) shall be as under :-

(1) Age 20-25 years Relaxable by 5 years only for Scheduled Castes/Scheduled Tribes and departmental candidates.

(2) Height 170 centimetres Relaxable by 4 cms. only for residents of hill areas e.g. Gorakhas, Garhwalis.

(3) Chest 81 centimeters to 85 centimeters Relaxable by 2 cms. for residents of hill areas.

(4) Educational Qualification Degree from a recognised University No relaxation

(5) Physical standard Sound health free from defect/deformity/disease both eyes vision 6/12 (without glasses. No colour blindness) No relaxation

(6) Reservation (i) For Scheduled Castes/Scheduled Tribes and Ex-servicemen etc. as per orders issued by Govt. from time to time.

(ii) For department candidates 10% of vacancies."

4. According to the interpretation placed upon the Rule by the Delhi High Court while 15 per cent of the total number of vacancies available for direct recruitment are reserved for Scheduled Castes, it is not permissible to reserve any vacancy for departmental candidates belonging to the Scheduled Castes. According to the High Court that would give departmental candidates belonging to the Scheduled Castes a double advantage. We fail to see how they get a double advantage. If we look at the break up given by the Respondents themselves, we see that out of a total of 170 vacancies, 15% of 170, that is, 25 vacancies are reserved for Scheduled Castes. Out of the 25 vacancies so reserved for Scheduled Castes, 10% of 25, that is 3 (correcting 2.5 to the nearest numeral) are reserved for departmental candidates belonging to the Scheduled Castes. The reservations for Scheduled Castes and departmental candidates operate vertically and horizontally. The reservation for departmental candidates is not in addition to the reservation for Scheduled Castes. We are told that that was how the department itself was interpreting the rule until their interpretation was upset by the Delhi High Court in Raj Kumar Singhs case. We do n
