Summarize the following court judgment. ivil Appeal No. 2967 of 1986. From the Judgment and Order dated 28.7.1986 of the Allahabad High Court in W.P. No. 1793 of 1980. Satish Chandra	 R.B. Mehrotra	 S.K. Mehta	 Atul Nanda and Aman Vachher for the Appellant. J.M. Khanna	 R.B. Misra and Ms. Anil Katiyar for the Respondents. The Judgment of the Court was delivered by SINGH	 J. This appeal is directed against the judgment and order of the High Court of Allahabad dated July 28	 1986 dismissing the appellant 's petition under Article 226 of the Constitution challenging the order of the Commissioner Varanasi Division dated February 13	 1980 setting aside the order of Municipal Board	 Jaunpur appointing the appellant as Tax Inspector. The Municipal Board	 Jaunpur issued advertisement invit ing applications for appointment to the post of Tax Inspec tor. The advertisement stated that the existing employees of the Revenue Department of the Municipal Board were eligible for consideration along with outsiders. Hari Mohan Respond ent No. 3 who was the senior most Tax Collector working in the Municipal Board	 Jaunpur was called for interview but he refused to appear for the interview on the plea that the post of Tax Inspector should have been exclusively filled by promotion and as he was the seniormost Tax Collector he should be promoted without considering any outsider. The Municipal Board ignored	 his claim and selected the appel lant	 and appointed 204 him to the post of the Tax Inspector by the order dated 11.3.78. Respondent No. 3 thereafter filed a claim petition before the Services Tribunal constituted under the U.P. Public Services Tribunals Act	 1976 but subsequently he withdrew the same on 23.12.79. Thereafter he filed a repre sentation to the Prescribed Authority i.e. the Commissioner Varanasi challenging appellant 's appointment to the post of Tax Inspector. The Commissioner by his order dated 13.2.80 set aside the order of the Municipal Board and cancelled the appellant 's appointment on the ground that the Respondent No. 3 was entitled to promotion in pursuance to the direc tions contained in the Government Order dated 10.4.50. The appellant filed a writ petition under Article 226 of the Constitution before the High Court challenging the order of the Commission. A learned Single Judge (B.D. Agarwal	 J.) of the High Court of Allahabad dismissed the writ petition and affirmed the order of the Commissioner on the findings that the appellant 's appointment was made in violation of the Government Order dated 10.4.50. Hence this appeal. After heating learned counsel for the parties at length we are of the opinion that the High Court committed manifest error in upholding the order of the Commissioner. The basic question which arises for consideration is whether the post of Tax Inspector	 under the provision of the U.P. Municipal ities Act	 1916 (hereinafter referred to as the 'Act ') or any rules framed thereunder or under the Government Order dated 10.4.1950 the post of Tax Inspector was required to be filled by promotion only and not by direct recruitment. The Prescribed Authority i.e.	 the Commissioner as well as the High Court both proceeded on the assumption that the Govern ment Order dated 10.4.50 had been issued by the State Gov ernment in exercise of its supervisory powers under section 71 of the Act and as such it was binding on the Municipal Board	 and the directions contained therein required the Municipal Board to fill up the post of Tax Inspector exclusively by promotion and not by direct recruitment. In making the appellant 's appointment as a direct recruit	 the Municipal Board acted in violation of the directions contained in the aforesaid Government Order	 therefore	 the appellant 's appointment was rendered illegal. The High Court upheld the order of the Prescribed Authority on these findings. Learned counsel for the appellant urged that the directions con tained in the Government Order dated 10.4.50 were ultra vires the State Government 's powers under section 71 of the Act. He placed reliance on Ramesher Prasad and Other vs Municipal Board	 Pilibhit	 AIR 1958 All. 363. The learned counsel further urged that the aforesaid decision was approved by two other learned Judges of the High Court in 205 Ram Kripal Garg vs State of U.P.	 Writ Petition No. 4556 of 1965 dated 16.9.66 and Inder Bahadur vs Municipal Board	 Mirzapur and Others	 Writ Petition No. 235 of 1970 dated 20.10.72 holding that the Government Order dated 10.4.50 was ultra vires. These decisions were placed before the learned Single Judge but he did not agree with the view taken in the aforesaid decisions instead he took a contrary view in holding that the Government Order dated 10.4.50 was valid and it required the Municipal Board to fill up the post of Tax Inspector only by promotion. It is well settled princi ple of judicial discipline as has been reiterated in a number of decisions of this Court that if a. Single Judge	 disagrees with the decision of another Single Judge	 it is proper to refer the matter to a larger Bench for an authori tative decision. But in the instant case the learned Judge acted contrary to the well established principles of judi cial discipline in ignoring those decisions. Section 71 of the Act before its amendment in 1964 did not confer power on the State Government to issue any direc tion regulating the conditions of service of Municipal employees. The view taken by the High Court in Ramesher Prasad case and followed in other two cases	 is correct. The High Court placed reliance on the Government Orders dated 27.4.57	 9.12.59 and 30.1.72 in holding that the directions contained in Government Order dated 10.4.50 were binding on the Municipal Board. We have gone through the aforesaid Government Orders and Notifications but we find nothing therein to clothe the Government Order dated 10.4.50 with statutory character. A Government Order declared ultra vires by High Court could not be revived by any subsequent Govern ment Order without there being any statutory power for the same. Moreover the aforesaid Government Orders and Notifica tions do not contain any direction requiring the Municipal Board to fill up the post of Tax Inspector exclusively by promotion. The High Court committed error in upholding the Commissioner 's order. We have closely scrutinised the Government Order dated 10.4.50 (Annexure 1 to the petition) with the assistance of the counsel for the parties. But even after conceding super visory power to the State Government to issue directions laying down conditions of service of Municipal employees	 we do not find any directions therein requiring a Municipal Board to fill the post of Tax Inspector only by promotion and not by direct recruitment. Learned counsel for the respondent placed reliance on paragraphs 5 and 6 of the Government Order in support of his contention that the post of Tax Inspector was required to be filled by promotion only. Paragraphs 5 and 6 of the Government Order read as under: 206 "5. In the case of the posts mentioned in the annexure promotions should	 as a rule	 be made from the lower to the higher posts or grades	 as the case may be	 in the same class of Service Subject to the general orders con tained in the above paragraphs. The prevailing practice 'of transferring at random officials in one class of service to another should be stopped. When direct recruitment to any post speci fied in the annexure had to be made it will be governed by the educational qualifications shown therein. Recruitments to posts from outside should	 however	 as far as possible be made by inviting applications through adver tisement in the press and making a selection therefrom preferably be means of a competitive test. Local Bodies may also be advised to form a Committee consisting of the Chairman or the President	 the Executive Officer or the Secre tary	 as the case may be	 and the principal administrative officer of the department concerned	 to make a selection from among the applicants for a vacant post by interviewing the after a competitive test. The actual appointment will	 however	 be made by the competent authority. " In order to ascertain the correct scope of the aforesaid paragraphs it is necessary to refer to the entire content of the Order. It appears that the U.P. Pay Committee made certain recommendations prescribing minimum qualifications in respect of employees of Local Bodies. The State Govern ment accepted the recommendations of the Pay Committee by its Resolution dated March 29	 1949 and in pursuance thereof it issued the Government Order dated 10.4.50 prescribing minimum qualifications for the employees of Local Bodies mentioned in the Schedule to the Order which included the post of Tax Inspector. Paragraph 2 of the Order directed that future vacancies on the promotion post will not ordi narily be given from a lower to higher post unless the officials holding the lower post	 possess the requisite educational qualifications prescribed for the higher post. Paragraph 3 directed that the posts of Head Clerks or Office Superintendent should be filled by promotion only from among the educationally qualified Head Clerks. It further directed that under no circumstances the posts of Head Clerks or Office Suptdt. be filled by direct recruitment from outside. Paragraph 4 directed the Municipal Boards to discontinue the posts of Sectional Head Clerks and to create posts of Office Head Clerks. Paragraphs 7 and 8 of the Order do not contain any directions 207 with regard to the question of promotion. Paragraph 5 as quoted earlier directed that promotion as a rule should be made from the lower to the higher post or grade in the same class of service subject to the directions contained in other paragraphs of the Order which means subject to the employee possessing the minimum qualifications prescribed for the higher post and the higher post should not be filled by transferring employees belonging to other class of serv ice. Paragraph 6 directed that in case of direct recruitment to any post as specified in the annexure of the Order it should be governed by the educational qualifications pre scribed in the Order and recruitment should be made in accordance with the procedure prescribed therein by consti tuting a committee and inviting applications. Paragraphs 5 and 6 as quoted above do not contain any directions requir ing Municipal Board to fill the post of Tax Inspector exclu sively by promotion. Though paragraph 3 as already noted directed that under no circumstances the post of Head Clerk or Office Suptdt. should be filled up by the direct recruit ment from outside	 no such direction for the post of Tax Inspector was issued	 therefore it was open to the Municipal Board to make appointment to the post of Tax Inspector either by direct recruitment or by promotion. In the instant case	 the Municipal Board	 Jaunpur gave opportunity to its employees working in the revenue class of service to appear for selection to the post of Tax Inspector in competition with outsiders. Respondent No. 3 however	 did not avail the opportunity for which he himself is to be blamed. The Municipal Board	 in our opinion	 acted within its jurisdiction in making appointment to the pOSt Of Tax Inspector by direct recruitment. The Commissioner	 as well as the High Court committed error in taking a contrary view. Subsequently	 the Act was amended and the statutory rules i.e.	 the U.P. Palika Centralised Service Rules have been framed regulating the conditions of service of Municipal employees and appointment to the post of Tax Inspector is regulated by Statutory Rules. The High Court committed serious error in upholding the order of the Government dated 13.2.80 in setting aside the appellant 's appointment without giving any notice or oppor tunity to him. It is an elementary principle of natural justice that no person should be condemned without hearing. The order of appointment conferred a vested right in the appellant to hold the post of Tax Inspector	 that right could not be taken away without affording opportunity of hearing to him. Any order passed in violation of principles of natural justice is rendered void. There is no dispute that the Commissioner 's Order had 208 been passed without affording any opportunity of hearing to the appellant therefore the order was illegal and void. The High Court committed serious error in upholding the Commis sioner 's Order setting aside the appellant 's appointment. In this view	 Orders of the High Court and the Commissioner are not sustainable in law. We accordingly	 allow the appeal and set aside the Order of the High Court as well as the Commissioner. There will be no order as to costs. T.N.A. Appeal allowed.

The Municipal Board	 Jaunpur invited applications for the post of Tax Inspector. The employees working in the Revenue Department of the Municipal Board were eligible for consideration alongwith the outsiders. Respondent No. 3	 the seniormost Tax Collector in Municipal Board	 was called for interview but he refused to appear on the plea that the post of Tax Inspector should be exclusively filled by promotion and being the seniormost Tax Collector he should be promoted without considering any outsider. Ignoring his claim the Municipal Board selected and appointed the appellant to the post of Tax Inspector. Respondent No. 3 represented to the Commissioner challenging the appellant 's appointment. The Commissioner set aside the order of the Municipal Board and cancelled the appellant 's appointment holding that pursuant to the directions contained in the Government 's Order dated 10.4.50	 Respondent No. 3 was entitled to promotion. The appellant challenged the Commissioner 's order before the High Court by filing a writ petition. Disagreeing with the decision of another Single Judge	 a Single Judge of the High Court dismissed the writ petition	 and affirmed the order of the Commissioner on the findings that the appellant 's ap pointment was made in violation of the Government 's Order dated 10.4.50. Hence this appeal. 202 Allowing the appeal and setting aside the order of the High Court	 this Court	 HELD: 1. The orders of the High Court and the Commis sioner are not sustainable in law. [208B] 1.1. It is a well settled principle of judicial disci pline that if a Single Judge disagrees with the decision of another Single Judge	 it is proper to refer the matter to a larger Bench for an authoritative decision. But in the instant case	 the learned Single Judge of the High Court acted contrary to the well established principles of judi cial discipline in ignorning those decisions. [205B C] 2. Section 71 of the U.P. Municipalities Act	 1916 before its amendment in 1964 did not confer power on the State Government to issue any direction regulating the conditions of service of Municipal employees. [205D] Ramesher Prasad and Ors. vs Municipal Board	 Pilibhit	 A.I.R. 1958 All. 363; Ram Kripal Garg vs State of U.P.	 Writ Petition No. 4556 of 1965 dated 16.9.66 and Inder Bahadur vs Municipal Board	 Mirzapur and Ors. 	 Writ petition No. 235 of 1970 dated 20.10.1972 approved. I Even after conceding supervisory power to the State Government to issue directions laying down conditions of service of Municipal employees	 there are no directions in the Government Order dated 10 4 50 requiring a Municipal Board to fill the post of Tax Inspector only by promotion and not by direct recruitment. Therefore	 it was open to the Municipal Board to make appointment to the post of Tax Inspector either by direct recruitment or by promotion. [205G; 207D] 2.2 In the instant case	 the Municipal Board gave oppor tunity to its employees working in the revenue class of service to appear for selection in competition with outsid ers. Respondent No. 3 however did not avail the opportunity for which he himself is to be blamed. The Municipal Board acted within its jurisdiction in making appointment to the post of Tax Inspector by direct recruitment. [207E] 2.3 A Govt. Order declared ultra vires by the High Court	 could not be revived by any subsequent Govt. Order without there being any statutory power for the same. [205E] 3. It is an elementary principle of natural justice that no person 203 should be condemned without hearing. The order of appoint ment conferred a vested right in the appellant to hold the post of Tax Inspector	 that right could not be taken away without affording an opportunity of hearing to him. Any order passed in violation of the principles of natural justice is rendered void. In the instant case	 there is no dispute that the Commissioner 's order had been passed with out affording any opportunity of hearing to the appellant. Therefore the order was illegal and void. The High Court committed serious error in upholding the Commissioner 's order setting aside the appellant 's appointment without giving any notice or opportunity to him. [207G H; 208A]
