Summarize the following court judgment. Appeal No. 381 of 1970. Appeal from the judgment and order dated December 22	 1969 of the Delhi High Court in Civil Writ No. 746 of 1969. Niren De	 Attorney General and section P. Nayar	 for the appellant. Sardar Bahadur	 Vishnu Bahadur	 and Yougindra Khushalani	 for respondent No. 1. G. section Chatterjee	 for respondent No. 2. Hegde	 J. 'In this appeal by certificate the only question that was canvassed before us was as regards the validity of the order contained in memorandum No. F. 16 42/68 S 1	 dated August 13	 1969 issued by the Government of India	 Ministry of Education and Youth Services	 retiring the 1st respondent compulsorily from government service in exercise of the powers conferred under cl. (j) of Fundamental Rule 56 with effect from August 14 1969. That order was attacked before the High Court on various grounds. The High Court rejected some of those grounds. It did not find it necessary to decide ' a few others but accepting the contention of the respondent that in making the order	 the appellant had violated the principles of natural justice	 it held that the impugned order is invalid The High Court accordingly issued a writ of certiorari quashing that order. Before us the only contention presented for our decision was whether the High Court was right in holding that in making the impugned order the appellant had violated the principles of natural justice. No other contention was taken before us. Hence we shall address ourselves only to that question. 793 Before proceeding to examine the contention above formulated it is necessary to set out the material facts. The 1st respondent. herein Col. J. N. Sinha successfully competed in the examination held by the Federal Service Commission in 1938 for the post of Extra Assistant Superintendent in the Survey of India Service. After selection	 he was appointed as an Extra Assistant Superintendent. He worked as probationer for a period of three years and thereafter he was confirmed in that post in 1941. During the second world war	 he Volunteered for active service in the army and was granted an emergency Commission in the army. He was granted a regular commission in the army with effect from October 23	 1942. In exercise of the powers conferred by the proviso to article 309 of the Constitution	 the President of India made on August 17	 1950 rules called the Survey of India (Recruitment from Corps of Engineering Officers) Rules	 1950 for regulating the recruitment and conditions of service of persons appointed from the Corps of Engineering Officers of the Defence Ministry to the Survey of ' India Class I Service. Rule 2 of the said Rules provides for the recruitment of Military Officers to the Survey of India Class I Service and Rule 3 provides that the recruited officers will be on probation for two years which may be extended by the Government on the advice of the Surveyor General. The 1st respondent was taken into the Survey of India Class I Service under Rule 2 of the aforesaid 1950 Rules as Deputy Superintendent Surveyor with effect from June 1951. Thereafter the President of India in .exercise of the powers under the proviso to article 309	 made on July 1	 1960 the Survey of India Class I (Recruitment) Rules	 1960 for regulating the recruitment of Survey of India Class I Service. The 1st respondent was subsequently promoted firstly as Superintending Surveyor and then as Deputy Director. After sometime he was promoted as Director and lastly as Director (Selection Grade). The last mentioned promotion was made with effect from October 27	 1966. On May 17	 1969	 Fundamental Rule 56(j) was amended. Thereafter on August 13	 1969	 the Ministry of Education and Youth Services issued the impugned order. The 1st respondent was given three months pay and allowances in lieu of three months notice prescribed in Fundamental Rule 56(1). The 1st respondent being aggrieved by that order	 challenged the validity of the same. As mentioned earlier	 the High Court accepted his plea. The Union of India has appealed against that order. Fundamental Rule 56(j) reads "Notwithstanding anything contained in this Rule the appropriate authority shall	 if it is of the opinion that it is in the public interest so to do have the absolute right 794 to retire any Government servant by giving him notice of not less than three months in writing or three months pay and allowances in lieu of such notice (i) if he is in Class I or Class II Service or post the age limit for the purpose of direct recruitment to which is below 35 years	 after he has attained the age of 50 years. (ii) In any other case after he has attained the age of 5 5 years. Provided that nothing in this clause shall apply to a Government servant referred to in clause (e) who entered Government service on or before 23rd July	 1966 and to a Government servant referred to in clause (f ) . " The order impugned merely says that in pursuance of cl. 5 6 	the President was	 pleased to decide that in public interest the 1st respondent should retire from government service with effect from August 13	 1969 and that he would be given three months pay and allowances in lieu of three months notice provided in the said rule. No reasons are given for compulsorily retiring the 1st respondent. Admittedly no opportunity was given to him to show cause against his compulsory retirement. The failure on ' the part of the concerned authority to give an opportunity to the 1st respondent to show cause against his compulsory retirement was held by the High Court to have amounted to a contravention of the principles of natural justice. The validity of Fundamental Rule 56(j) was not questioned before the High Court nor before us. Its validity is not open to question in view of the decision of this Court in T. G. Shivacharana Singh and Ors. vs State of Mysore(1). Fundamental Rule 56(j) in terms does not require that any opportunity should be given to the	 concerned government servant 'to show cause against his compulsory retirement. A government servant serving under the Union of India holds his office at the pleasure of the President as provided in article 310 of the Constitution. But this "Pleasure" doctrine is subject to the rules or law made under article 309 as well as to the conditions prescribed under article 311. Rules of natural justice are not embodied rules nor can they be elevated to the position of fundamental rights. As observed by this Court in Kraipak and Ors. vs Union of ' India(2) "the aim of rules of natural justice is to secure justice or to put it negatively to prevent miscarriage of justice. These rules can operate only in areas not covered by any law validly made. In other words they do not supplant the law but supplement it. " It (1) A. I. R. (2) A. I. R. 795 is true that if a statutory provision can be read consistently with the principles of natural justice. the courts should do so because it must be presumed that the legislatures and the statutory authorities intend to act in accordance with the principles of naural justice. But if on the other hand a statutory provision either specifically or by necessary implication excludes the application of any or all the principles of natural justice then the court cannot ignore the mandate of the legislature or the statutory authority and read into the concerned provision the principles of natural justice. Whether the exercise of a power conferred should be made in accordance with any of the principles of natural justice or not depends upon the express words of the provision conferring the power	 the nature of the power conferred	 the purpose for which it is conferred / and the effect of the exercise of that power. Now coming to the express words of Fundamental Rule 56(j)	 it says that the appropriate authority has the absolute right to retire a government servant if it is of the opinion that it is in the public interest to do so. The right conferred on the appropriate authority is an absolute one. That power can be exercised subject to the conditions mentioned in the rule. ' one of which is that the concerned authority must be of the opinion that it is in public interest to do so. If that authority bona fide forms that opinion	 the correctness of that opinion cannot be challenged before courts. It is open to an aggrieved party to contend that the requisite opinion has not been formed or the decision is based on collateral grounds or that it is an arbitrary decision. The 1st respondent challenged the opinion formed by the government on the ground of mala fide. But that ground has failed. The High Court did not accept that plea. The same was not pressed before us. The impugned order was not attacked on the ground that the required opinion was not formed or that the opinion formed was an arbitrary one. One of the conditions of the 1st respondent 's service is that the government can choose to retire him any time after he completes fifty years if it thinks that it is in public interest to do so. Because of his compulsory retirement he does not lose any of the rights acquired by him before retirement. Compulsory retirement involves no civil consequences. The aforementioned rule 56(j) is not intended for taking any penal action against the government servants. That rule merely embodies one of the facets of the pleasure doctrine embodied in article 3 1 0 of the Constitution. Various considerations may weigh with	 the appropriate authority while exercising the power conferred under the rule. In some cases	 the government may feel that a particular post may be more usefully held in public interest by an officer more competent than the one who is holding. It may be that the officer who is holding the post is not inefficient but the appropriate authority may prefer to have a more efficient officer. It may further be 796 that in certain key posts public interest may require that a person of undoubted ability and integrity should be there. There is no denying the fact that in all organizations and more so in government organizations	 there is good deal of dead wood. It is in public interest to chop off the same. Fundamental Rule 56(j) holds the balance between the rights of the individual government servant and the interests of the public. 'While a minimum service is guaranteed to the government servant	 the government is given power to energise its machinery and make it more efficient by compulsorily retiring those who in its opinion should not be there in public interest. It is true that a compulsory retirement is bound to have some adverse effect on the government servant who is compulsorily retired but then as the rule provides that such retirements can be made only after the officer attains the prescribed age. Further a compulsorily retired government servant does not lose any of the benefits earned by him till the date of his retirement. Three months ' notice is provided so as to enable him to find out other suitable employment. In our opinion the high Court erred in thinking that the compulsory retirement involves civil consequences. Such a retirement does not take away any of the rights that have accrued to the government servant because of his past service. It cannot be said that if the retiring age of all or a section of the government servants is fixed at 50 years	 the same would involve civil consequences. Under the existing system there is no uniform retirement age for all government servants. The retirement age is fixed not merely on the basis of the interest of the government servant but also depending on the requirements of the society. The High Court was not justified in seeking support for its conclusion from the decision of this Court in State of Orissa vs Dr. (Miss) Binapani 'Dei and ors.(1) and A. K. Krailpak vs Union of India( '). In Binapani Dei 's case( ') Dr. Binapani Dei 's date of birth was refixed by the government without giving her proper opportunity to show that the enquiry officer 's report was not correct. It is under those circumstances this Court held that the order refixing the date of birth was vitiated for failure to comply with the principles of natural justice. Therein the impugned order took away some of the existing rights of the petitioner. In Krapak 's case( ')	 a committee consisting of Chief Conservator of	 Forest	 Kashmir and others was appointed to recommend names of the officers from Kashmir Forest Service for (1) ; (2) A.I.R. 1970 S.C. 150. 797 being selected for the Indian	 Forest Service. The Chief Conservator of Forests	 Kashmir was one of the candidates for selection. Further it was established therein that some of the officers who competed with him had earlier challenged his seniority and consequently his right to be the Chief Conservator and that dispute was pending. Under those circumstances this Court held that there was contravention of the principles of natural justice. For the reasons mentioned above	 we are unable to agree with the conclusion reached by the High Court that the impugned order is invalid. We accordingly allow this appeal	 set aside the judgment and decree of the High Court and dismiss the writ petition. In the circumstances of the case we make no order as to costs. [The Court by order dated November 18	 1970 and January 19	 1971 on an application for review filed by the respondent vacated its order dismissing the writ petition. Instead	 the proceedings were remanded to the High Court for decision on such points as were not	 dealt with and decided in the judgment of that court. Ed.] G.C. Appeal allowed. Proceedings remanded.

The first respondent joined the post of Extra Assistant Superintendent in the Survey of India Service in 1938. Later he was taken into the Class I Service of the Survey of India and rose to the post of Deputy Director. He also officiated as Director. On August 13	 1969 the President of India pleased by an order under Rule 56(j) of the Funda mental Rules to compulsorily retire the first respondent from Government service. No reasons were given in the order. The appellant challenged the order by a writ petition in the High Court. The failure on the part of the concerned authority to give opportunity to the first respondent to show cause against his compulsory retirement was held by the High Court to have amounted to a contravention of the principles of natural justice. Against the judgment of the High Court the Union of India appealed. HELD : Rules of natural justice are not embodied rules nor can they be elevated to the position of fundamental rights. As observed by this Court in Kralpak 's case these rules can operate only in areas not covered by any law validly made. If a statutory provision can be read consistently with the principles of natural justice	 the Courts should do so because it must be presumed that the legislatures and the statutory authorities intend to act in accordance with the principles of natural justice. But on the other hand a statutory provision either specifically 'or by necessary implication excludes the application of any or all the principles of natural justice then the court cannot ignore the mandate of the legislature or the statutory authority and read with the concerned provision the principles of natural justice. Whether the exercise of a power conferred should be made in accordance with any of the principles of natural justice or not depends upon the express words of the provision conferring the power	 the nature of the power conferred	 the purpose for which it is conferred and the effect of the exercise of the power. [794 G 795 C] Fundamental Rule 56(i) does not in terms require that any opportunity should be given to the concerned Government servant to show cause against his compulsory requirement. It says that the appropriate authority has the absolute right to retire a government servant if it is of the opinion that it is in the public interest to do so. If that authority bona fide forms that opinion the correctness of that opinion cannot be challenged before courts	 though it is open to an aggrieved party to contend that the requisite opinion has not been formed or the decision is based on collateral grounds or that it is an arbitrary decision. The respondent had not challenged the impugned order on any of these grounds. [795 D F] Compulsory retirement does not involve any civil consequence. A person retired under Rule 56(i) does not lose any of the rights acquired 792 by him before retirement. The rule is not intended for taking any penal action against government servants. It merely embodies one of the facets of the pleasure doctrine embodied in article 310 of the Constitution. The rule holds the balance between the	 rights of the individual government servant and the interests of the public. While a minimum service is guaranteed to the government servant	 the government is given power to energise its machinery and make it more efficient by compulsorily retiring those who in its opinion should not be there in public interest. Three months notice is provided to enable the retired employee to find out other suitable employment. [795 G 796 B] On the above view of the law	 namely	 that no notice to show cause was required	 the appeal must be allowed. T. G. Shivacharana Singh vs State of Mysore	 A.I.R. 1965 S.C. 280.
