Bihar Ophthalmic Assistant Joint Cadre Rule (recruitment and service conditions) Rule, 2011 has been amended vide Notification dated 06.03.2019, as Bihar Ophthalmic Assistant Joint Cadre Rule (recruitment and service conditions) (Amendment) Rule, 2019 wherein minimum education qualification prescribed for direct recruitment to the post of basic category post shall be Intermediate/10+2 pass (Physics, Chemistry, Biology with English).

Since the date of coming into force of Bihar Ophthalmic Assistant Joint Cadre Rule (recruitment and service conditions) Rule, 2011 the educational qualification mandated for direct recruitment to the post of basic category post shall be I.Sc. / 10+2 (Biology) passed and having a pass certificate of Diploma course prescribed for ophthalmic Assistant". 15. 14. Since the date of coming into force of Bihar Ophthalmic Assistant Joint Cadre Rule (recruitment and service conditions) Rule, 2011 the educational qualification mandated for direct recruitment to the post of basic category post shall be I.Sc. / 10+2 (Biology) passed and having a pass certificate of Diploma course prescribed for ophthalmic Assistant". 15. In consonance with the Ophthalmic Cadre Rules, in the academic prospectus published by the BCECE, Board, Patna for Diploma Certificate Examination, the educational qualification for taking admission in Ophthalmic Assistant Course has been incorporated as Intermediate Science or Equivalent with Physics, Chemistry, Biology and English. 16. In the academic prospectus published by the BCECE, Board, Patna for Diploma Certificate Examination, 2021, the educational qualification Intermediate Science either with Mathematics or Biology was incorporated for Ophthalmic Assistant only for the purpose of taking admission in Ophthalmic Assistant course in wider perspective, but in the matter of appointment of Ophthalmic Assistant, the State Government has taken policy decision and framed the relevant Rules i.e. Bihar Ophthalmic Assistant Cadre (Recruitment and Service Condition) Rules, 2011 and Amended Rules, 2019 in exercise of powers conferred by proviso to Article 309 of the Constitution of India. 17. In the academic prospectus published by the BCECE, Board, Patna for Diploma Certificate Examination, 2022, the Educational Qualification for taking admission in Ophthalmic Assistant Course has been corrected and incorporated as per the Ophthalmic Cadre Rules i.e. Intermediate Science or Equivalent with Physics, Chemistry, Biology and English. 18. I.Sc./ 10+2 with Biology has been made minimum essential qualification in the year 2011 itself immediately after coming into effect of Rules, 2011, and now, by the amended Rules, 2019, the qualification has merely been made more specific and clear by providing that the educational qualification shall be I. Sc./10+2 pass (with Physics, Chemistry, Biology & English) as, in the original rule only I.Sc./ 10+2 (Biology) pass was mentioned. 19. Petitioners have passed the course of Diploma in Ophthalmic Assistant from the Government Institutes before the coming into force of Bihar Ophthalmic Assistant Cadre (Recruitment and Service Condition) Rules, 2011 with prescribed educational qualification for taking admission in the course of diploma in Ophthalmic Assistant as +2 intermediate, science or other equivalent examination with physics chemistry and English besides mathematic or biology. They formed a different class from those who have passed the course of Diploma in Ophthalmic Assistant from the Government Institutes after the coming into force of Bihar Ophthalmic Assistant Cadre (Recruitment and Service Condition) Rules, 2011 with prescribed educational qualification as Intermediate Science or Equivalent with Physics, Chemistry, Biology and English. 20. In the matter of recruitment to any cadre, it is a matter of policy and depends upon variable circumstances to lay down criterion of eligibility and sources from which the recruitment shall be made through different methods. Such a lying down of a policy cannot be per se said to be arbitrary, unreasonable and violative of Article 14 and 16 of the Constitution. 21. Heard learned Senior counsel for the petitioners as well as learned Senior counsel for the respondents. 22. It is an admitted fact that before coming into force Bihar Opthalmic Assistants joint cadre (Recruitment and Service Conditions) Rules, 2011 admission in Diploma Course for Opthalmic Assistant through competitive examination students passing intermediate (Science) with Mathematics or Biology were eligible to appear in the competitive examination and on being successful in competitive examination were admitted in Diploma Course of Ophthalmic Assistant, however, after coming into force of Bihar Opthalmic Assistants joint cadre (Recruitment and Service Conditions) Rules, 2011 admission in Government institute was confined to students passing intermediate (Science) examination with biology as such no student passing intermediate (Science) with Mathematics could take admission in Diploma Course of Ophthalmic Assistant after 2011 after framing of Bihar Opthalmic Assistants joint cadre (Recruitment and Service Conditions) Rules, 2011 (except for the year-2021). 23. It is equally true that prior to 2011 students passing intermediate (Science) with Biology or Mathematics were eligible for admission in Diploma Course in Opthalmic Assistant. 23. It is equally true that prior to 2011 students passing intermediate (Science) with Biology or Mathematics were eligible for admission in Diploma Course in Opthalmic Assistant. It is also apparent from records that in the year 2006, process for appointment on the post of Opthalmic Assistant was undertaken by the State Government in which also eligibility was subsequently amended as Diploma Course in Opthalmic Assistant and intermediate (Science) with Mathematics or Biology, for which a letter dated 12.02.2007, was issued by the Joint Secretary, Department of Health and Family Welfare, Government of Bihar (Annexure-4), which is reproduced hereinbelow:— fcgkj ljdkj LokLFk; ,oa iñdñ foHkkx izs"kd] teh:n~nhu valkjh ljdkj ds la;qDr lfpoA lsok esa] lfpo] fcgkj deZpkjh p;u vk;ksx] fcgkj] iVukA iVuk] fnukad 12-02-2007 fo"k;%&us= lgk;d ds inksa ij fu;qfDr gsrq izdkf'kr foKkiu esa fuèkkZfjr vgZrk ds la'kksèku ds lacaèk esaA izlax% LokLF; foHkkx ds i=kad 315(1B) fnukad 01-06-2005] 612¼11½ fnukad 25-08-2006 ,oa i=kad 21(11)] fnukad 04-01-2007A egk'k; mi;qZDr fo"k;d izlaxkèkhu i=k ds lacaèk esa funs'kkuqlkj dguk gS fd us= lgk;d ds inksa ij fu;qfDr gsrq vk;ksx }kjk fnukad 23-01-2007 dks nSfud lekpkj i=ksa esa izdkf'kr foKkiu lñ&2307 esa fuèkkZfjr vgZrk dh mYysf[kr dafMdk esa fuEu :isu la'kks/ku djus dh Ñik dh tk;& 1- 'kS{kf.kd ;ksX;rk-&vkbZñ,lñlhñ ck;ksykWth vFkok xf.kr (Biology or Mathematics) esa mÙkh.kZA 2- rduhdh ;ksX;rk-&fcgkj ljdkj }kjk ekU;rk izkIr ljdkjh@xSj ljdkjh@¼ljdkjh½ laLFkkuksa ls us= lgk;d ds nks ¼2½ o"khZ; fMIyksek ikB~;Øe ds izR;sd fo"k; esa 50 Áfr'kr U;wure vad ds lkFk mÙkh.kZ gksuk vko';d gksxkA 3- iSjk esfMdy@iSjk MsUVy ijh{kk lfefr }kjk us= lgk;d ds nks ¼2½ o"khZ; fMIyksek ikB~;Øe dh ekpZ] 2007 esa vk;ksftr gksus okyh vfUre ijh{kk esa lfEefyr gksus okys mEehnokj Hkh vkoaVu ns ldsaxsA lk{kkRdkj dh frfFk dks mÙkh.kZrk dk izek.k i= izLrqr djuk vfuok;Z gksxk vU;Fkk mudh vgZrk lekIr dj nh tk;xhA vuqjksèk gS fd ;Fkk LFkku mi;qZDr la'kksèku djrs gq, iqu% la'kksfèkr foKkiu izdkf'kr djkus dh Ñik dh tk;A fo'oklHkktu ¼teh:n~nhu valkjh½ ljdkj ds la;qDr lfpo 24. It is quite surprising that during pendency of writ petition prospectus for entrance examination 2021 was issued for admission in Diploma Course in Opthalmic Assistant and again in prospectus eligibility for admission in Diploma course of Opthalmic Assistant has been made Intermediate (Science) with Physics, Chemistry, English and Mathematics or Biology which depicts a very sorry state of affairs in which Department is functioning. 25. 25. Having heard learned counsel for the parties, this Court finds that once admission to candidates passing Intermediate (Science) with Biology or Mathematics have been permitted to appear in the competitive examination for admission in Diploma course of Opthalmic Assistants and after successfully completing the diploma course and getting diploma certificate in Opthalmic Assistant, State cannot deny them opportunity of appointment on the post of Opthalmic Assistant and denial of opportunity for appointment on the post of Opthalmic Assistant is arbitrary, unreasonable and discriminatory and offends Article 14 and 16 of the Constitution of India. 26. Respondent-Health Department, in the year 2006 also permitted selection of candidates on the post of Opthalmic Assistant in the State Government having passed Intermediate (Science) with Biology or Mathematics and same principle will apply in the case of petitioners also and they are also governed by letter dated 12.02.2007 as contained in (Annexure 4 page 107). 27. Once the State government has permitted students passing Intermediate (Science) with Mathematics or Biology for admission in the Diploma course of Opthalmic Assistant and having obtained diploma certificate State cannot deny them appointment on the ground that they have passed Intermediate (Science) examination having Physics, Chemistry, English and Mathematics and not Biology same being arbitrary and cannot stand twin test of reasonableness and fairness. 28. Accordingly, petitioners who were admitted in the Diploma Course in Opthalmic Assistant before framing of recruitment Rules-2011 are eligible to be considered for appointment on the post of Opthalmic Assistant, since there is already a direction issued by this Court to accept the application forms of candidates passing Intermediate (Science) with Physics, Chemistry, English and Mathematics, as such the Bihar State Technical Commission is directed to prepare merit list treating petitioners to be eligible for appointment on the post of Opthalmic Assistant. Accordingly, the writ petitions are allowed.
