Summarize the following court judgment. onstrued. One should not concentrate too much on one rule and pay too little atten tion on the other	 for that would lead astray and result in hardship	 such construction should be avoided. [955C D] & CIVIL APPELLATE JURISDICTION: Civil Appeal No. 30373038 of 1984 From the Judgment and Order dated 12.12. 1983 of the Bombay 950 High Court in W.P. No. 1189 of 1980. S.K. Dholakia	 A.S. Bhasme and A.M. Khanwilkar for the Appellant. N.B. Shetya	 S.B. Bhasme	 section Ramachandran	 R. Ramachan dran	 Maknand Adkar and Mrs. M. Karanjawala for the Respond ents. The Judgment of the Court was delivered by K. JAGANNATHA SHETTY	 J. These two appeals by special leave are by the State of Maharashtra. They are directed against the judgment of the High Court of Bombay dated 12th January	 1983 by which the High Court issued the following two directives to the State Government: "(1) To recast the Revised/Final Sen iority List dated 20.12. 1982 vis a vis the persons shown in the category of 'Late Pass ing ' and assign them seniority strictly in accordance with Rule 2 and the other Govern ment orders referred to in Paragraph 96 of the judgment; and (2) The seniority in the Superintend ent 's cadre so fixed should also be considered as seniority for further promotions. " The background to these directives is	 in outline	 this: Respondents 1 to 8 are Assistant Secretaries/Section Officers/ Superintendents in different departments of the Government of Maharashtra. The State Government prescribed departmental examinations as a condition precedent for promotion to the cadre of Superintendents. The examination was required to be conducted every year	 and the officials have to pass within the stipulated period. Those who could not pass within the time frame would lose their seniority but they will be promoted as and when they qualify them selves. The Government for some reason or the other could not hold the examinations every year. Particularly in 1968	 1969 & 1970	 the Government did not hold the examinations. The Government	 however	 did not pass any order extending the period prescribed for passing the examinations	 nor promoted the seniors subject to their passing the examina tion. The juniors who qualified themselves were promoted overlooking the case of seniors and seniors were only pro moted upon their passing the examination. In the cadre of Superinten 951 dents	 however	 the Government revised the seniority list so as to reflect the rankings in the lower cadre irrespective of the date of promotion. The validity of the revision of seniority was challenged before the High Court. The High Court conceded the power to the Government to relax the rules relating to passing of the examination in case of hardship	 but refused to recognise the power of the Govern ment to give seniority to those who could not pass the examination within the time schedule. The High Court was of opinion that without specific orders of the Government relaxing the conditions of the rules	 the persons could not be given seniority for 'Late Passing '. There are also other reasons given by the High Court which we will presently consider. But before that	 it is important that we should have a chronology of the relevant rules and resolutions of the Government. It is as follows: On 22nd August	 1951	 the Government made a resolution prescribing departmental examination for the members of the Upper Division of the Subordinate Secretariat Service	 and further directing that only those persons who pass the examination should be promoted as Superintendents. The accompanying rules (The 1951 Rules) thereunder provided the procedure for passing the examination as well as the conse quences of failure to pass the examination. On 24th August	 1955	 the Government framed rules (The 1955 Rules) under the proviso to Article 309 of the Constitution specifically providing power to dispense with	 or relax	 the requirements of the operation of any rule regulating the conditions of service of Government servants; or of any class thereof if it causes undue hardships in any particular case. On 15th January	 1962	 the Government issued a circular purporting to restrict the scope of the rule permitting relaxation only in respect of travelling allowance rules	 leave rules	 etc. The circular also clarified that the 1955 Rules could not be invoked for conferring benefit on an individual by relaxing the conditions relating to recruitment	 promotion	 grant of extension of service or re employment. On 28th December	 1961	 the Government made the revised rules in supersession of the 1951 Rules. They were brought into force with effect from 1st January	 1962 (the 1962 Rules). They were made appl icable to all persons recruited to the Upper Division of the Subordinate Secretariate Service on or after that date and also to those who have been in service prior to 1st Jan uary	 1962 unless they had already passed the examination under the 1951 Rules. The rules 1 to 5 are as follows: "1. Every member of the Upper Divi sion of the Subordinate Secretariat Service will be required to pass within 952 nine years from the date of his entry in the Upper Division	 a departmental examination for promotion to the posts of Superintendents according to the prescribed syllabus. For being eligible to appear for the examination a candidate must have passed the Post Recruit ment Training Examination for Junior Assistant and must have also completed not less than five years ' continuous service in the Upper Division. (2) Subject to Rule 1	 a candidate will be allowed to appear for the examination in three chances which must be availed of within a period of four years. This period of 4 years will not be extended for any reasons irrespective of the fact whether a candidate has availed himself of 3 chances or not during the period. Similarly no candidate will be allowed to take during this period more than 3 chances. A candidate who does not pass the examination at the end of 9 years service in the Upper Division	 will lose his seniority to all those candidates who pass the examination before he passes it. (3) No persons shall be appointed to the post of Superintendent unless he has passed the Superintendents ' Examination. Provided that this rule shall not apply to short term vacancies not exceeding two months. (4) Subject to the condition of loss of seniority laid down in rule 2	 a candidate will be allowed to take the examina tion in any number of chances after the com pletion of 9 years ' service. (5) The examination will be held once a year. XXX XXX XXX XXX " On December 28	 1970	 proviso to above rule 3 has been added. The said proviso reads: "Provided that if the Superintendent 's Examination is not held in any year	 a person who has completed 9 years service and who has not exhausted all the permissible chances	 may be promoted to the post of Superintendent	 provided further that he is otherwise suitable for promo tion	 subject to the clear condition that he will have to pass 953 the examination at the earliest opportunity whenever it is held." "It is further clarified that promo tions to the posts of Superintendents should	 in view of the above amendments	 be given only after ensuring that there are no persons who have passed the Superintendents Examination earlier for being promoted to the posts of Superintendents. " We may incidentally refer to the subsequent rules made by the Government	 although it is not applicable to the present case. On June 6	 1977	 the Government framed the rules called "The Maharashtra Government Subordinate Service Rules	 1977". Rule 7 of the rules provides that if	 for any reason	 the examination is not held in any particular year	 that year shall be excluded in computing the period speci fied under the rules. This is	 indeed	 the true reflection of the underlying concept of purpose of the earlier rules. Against this backdrop	 we may now consider whether the Government was justified in re arranging the seniority by giving benefit to persons in the category of "Late Passing". We are not concerned herein about the seniority of persons in whose favour the Government has made individual orders extending the period for passing the examination. We will consider such cases a little later. For the present	 we may examine the rights of those "Late Passing" where the Government has not made any specific order relaxing the conditions for passing the examination. Under the 195 1 Rules	 the candidate could appear for the examination after two years of his entering into the cadre. He has three chances and he must pass within 6 years of his joining service. Under the 1962 Rules the scheme provided was slightly different. Under that scheme	 candidate was allowed to take the examination only after completing five years service in the cadre. He had three chances for taking the examination and that must be availed of within four years. That means he must pass the examination within the 9 years ' service. Under both the Rules	 the Government was required to hold the examination every year	 but no examination was held in 1968	 1969 & 1970. This is not in dispute. For a proper appreciation of the question raised	 we must first try to understand the hardship resulted by not holding the examination in 1968	 1969 & 1970. It is as follows: The candidates recruited in 1960 have lost one chance in 1968. Those recruited in 1961 are deprived of two chances in 1968 and 1969. The candidates recruited in 1962 are 954 denied of three chances in 1968	 1969 & 1970 and those of the year 1963 have lost two chances in 1969 and 1970. The last batch to lose one chance in 1970 is of the year 1964. The aforesaid Rules expressly provided power to the Government to grant more chances for passing the examination in any individual case or in class of cases. Under the 1955 Rules	 the Government preserved power to dispense with	 or relax the requirements of any rule regulating "the condi tions of service of government servants; or of any class thereof". In the exercise of this power	 the Government could dispense or relax the operation of any rule	 if it causes undue hardships in any particular case. It is need less to state that this power includes the power to relax the conditions prescribed for promotion since promotion is a condition of service. There is no restriction as to the exercise of the power or discretion. The High Court	 howev er	 has observed that the scope of this power has been constrained by the circular dated 15th January	 1962. The circular states that the 1955 Rules permitting relaxation cannot be utilised to relax the rules which regulate condi tions of service. It further states that the scope of the Rules should be limited only to matters relating to travel ling allowance	 leave	 etc. But this appears to be an exer cise in vain. The circular is an executive instruction whereas the 1955 Rules are statutory since framed under the proviso to Article 309 of the Constitution. The Government could not have restricted the operation of the statutory rules by issuing the executive instruction. The executive instruction may supplement but not supplant the statutory rules. The High Court was in error in ignoring this well accepted principle. When we turn to the 1962 Rules with the amendments made in 1970	 it becomes more clear about the power of the Gov ernment to relax the conditions for passing the examination. The proviso dated 28th December	 1970 to rule 3 specifically provides that if the examination is not held in any year	 a person Could be promoted to the cadre of Superintendent if he has completed nine years ' service. The only condition is that he should not have exhausted all the permissible chances. The promotion	 made should be subject to the condi tion that he will have to pass the examination at the earli est opportunity whenever it is held. The benefit of this proviso was evidently not extended to any of the persons falling into the category of "Late Passing". Counsel for the contesting respondents however	 urged that the proviso does not entitle the candidate to get his legitimate seniority if 955 he does not pass the examination at the end of nine years ' service. He depended upon rule 2 of the 1962 Rules which states that the candidate who does not pass the examination within 9 years ' service will lose his seniority to all those candidates who pass the examination earlier. He also argued that the proviso is only to rule 3 and not to rule 2 and the Government has no power to restore the seniority of a person who has lost it by the operation of rule 2. This is a question of construction of the rules which form part of the scheme prescribing a condition for promo tion. We do not have to reflect upon the rules of interpre tation since they are well settled. They are now like the habits of driving which have become ingrained. They come to our assistance by instinct. We are to use the different rules meticulously to give effect to the scheme as we use the clutch	 brake and accelerator for smooth driving. These rules are to be harmoniously construed. We should not con centrate too much on one rule and pay too little attention on the other. That would lead us astray and result in hard ship. We must avoid such construction. Rule 2 of the 1962 Rules no doubt states that a candidate who does not pass the examination at the end of nine years ' service will lose his seniority. But this rule cannot be read in isolation as the High Court did. It has to be read along with the other rules since it is a part of the scheme provided for promotion. Rule 5 requires the Government to hold the examination every year. This rule is the basis of the entire scheme and the effect of other rules depends upon holding the examination. If examination is not held in any year	 the rule 2 cannot operate to the prejudice of a person who has not exhausted all his chances. The person who has not exhausted the avail able chances to appear in the examination cannot be denied of his seniority. It would be unjust	 unreasonable and arbitrary to penalise a person for the default of the Gov ernment to hold the examination every year. That does not also appear to be the intent or purpose of the 1962 Rules. If the examination is not held in any year	 the person who has not exhausted all the permissible chances has a right to have his case considered for promotion even if he has completed 9 years ' service. The Government instead of promoting such persons in their turn made them to wait till they passed the examination. They are the persons falling into the category of "Late Passing". To remove the hardship caused to them the Government wisely restored their legiti mate seniority in the promotional cadre. There is	 in our opinion	 nothing improper or illegal in this action and indeed	 it is in harmony with the object of the 1962 Rules. 956 This takes us to the question whether the Government was justified in individual cases to relax the period for pass ing the examination. It is said that the number of persons failing into this category are not more than five. In the rejoinder filed on behalf of the Government	 it is stated that the Government made some orders extending the period for individuals to pass the examination on administrative grounds or on some genuine hardships. It is also stated that such orders were made upon recommendations by the respective departments and those persons passed the examination within the period extended. There is no reason to doubt the cor rectness of these statements made in the rejoinder. The power to relax the conditions of the rules to avoid undue hardship in any case or class of cases cannot now be gain said. It would be	 therefore	 futile for the respondents to make any grievance. In the result and for the reasons stated	 we allow these appeals and in reversal of the judgment of the High Court	 we dismiss the writ petitions filed by the contesting re spondents. In the circumstances of the case	 however	 we make no order as to costs. Y.L. Appeals allowed.

Respondents 1 to 8 are Assistant Secretaries/Section Officers/ Superintendents who are working in different departments of the State of Maharashtra. Under the Rules governing their Service conditions the Govt. had prescribed Departmental Examination for promotion to the cadre of Superintendents; the passing of the examination was a condi tion precedent for the officials for being promoted as superintendents. The Examination in question was required to be conducted every year and the officials were required to pass the same within the stipulated period; and the offi cials who were not able to pass the said examination within the prescribed period were to lose their Seniority	 but they were permitted to take the examination in any number of chances after the expiry of the stipulated period and they were to be promoted only when they qualify themselves. The Govt. as required under the Rules	 could not hold the exami nation every year particularly in the years 1968	 1969 & 1970. The Govt. neither extended the period within which the officials were required to pass the examination nor promoted the seniors in the cadre of Superintendents subject to their passing the examination and instead thereof the juniors in the cadre who had qualified in the examination were promoted to the cadre of Superintendents. The seniors in the cadre were promoted only when they qualified the examination i.e. later in point of time. The Govt. issued a revised Seniority List relating to the cadre of Superintendents. In the said List the Respond ents herein were shown juniors to those persons who had not only qualified the Dept. Examination later in point of time but also promoted after them. Being aggrieved	 the Respond ents herein challenged the validity of the revi 948 sion of the Seniority List as also the validity of the Rules being violative of article 14 & 16 of the Constitution by filing a Writ Petition in the Bombay High Court. The High Court allowed the Writ Petn. and issued the following two directives to the State Govt. (1) To recast the Revised/Final Seniority List dated 20.12.1982 vis a vis the persons shown in the Category of "Late Passing" after considering the objections of the Writ Petitioners and Ors. and assign them seniority strictly in accordance with Rule 2 and the other Government Orders referred to in paragraph 96 of the Judgment	 and (2) The Seniority in the Superintendent 's Cadre so fixed should also be considered as seniority for further promo tions. Being dissatisfied with the said order of the High Court	 the State of Maharashtra filed appeals in this Court after obtaining Special Leave. Allowing the appeals this Court	 HELD: Under the 1951 Rules	 the candidate could appear for the examination after two years of his entering into the cadre. He had three chances and he must pass within six years of his joining Service. Under the 1962 Rules a candi date was allowed to take the examination only after complet ing five years service in the cadre. He had three chances for taking the examination and that must be availed of within four years. That means he must pass the examination within 9 years ' service. Under both the Rules	 the Govt was required to hold the examination every year	 but no examina tion was held in 1968	 1969 and 1970. [953F G] Those recruited in 1961 are deprived of two chances in 1968 three chances in 1968	 1969 & 1970 and those of the year 1963 have lost two chances in 1969 & 1970. The last batch to lose one chance in 1970 is of the year 1964. [953H; 954A] Under the 1955 Rules	 the Government preserved power to dispense with or relax the requirements of any rule regulat ing "the conditions of service of Government servants; or of any class thereof". [954B] 949 There is no restriction as to the exercise of the power or discretion.[954C] The Circular dated January 15	 1962 is an executive instruction whereas the 1955 Rules are statutory since framed under the proviso to article 309 of the Constitution. The Government could not have restricted the operation of the Statutory Rules by issuing the executive instruction. The executive instruction may supplement but cannot supplant the statutory rules. [954D E] Rule 2 of the 1962 Rules no doubt states that a candi date who does not pass the examination at the end of 9 years service will lose his seniority. But this rule cannot be read in isolation. [955D] If examination is not held every year. The rule cannot operate to the prejudice of a person who has not exhausted all his chances. The person who has not exhausted the avail able chances to appear in the examination cannot he denied of his seniority. It would be unjust	 unreasonable and arbitrary to penalise a person for the default of the Gov ernment to hold the examination every year. That does not also appear to be the intent or purpose of the 1962 Rules. [955E F] The Govt. instead of promoting such persons in their turn made them to wait till they passed the examination. They are the persons failing into the category of "Late Passing". To remove the hardship caused to them the Govt. wisely restored their legitimate seniority in the promotion al cadre. There is nothing improper or illegal in this action and indeed	 it is in harmony with the object of 1962 Rules. [955G H] The Court need not have to reflect upon the Rules of interpretation since they are well settled. They are now like the habits of driving which have become ingrained. They come for assistance by instinct. The different rules have to be used meticulously to give effect to the scheme as the clutch	 brake and accelerator are used for smooth driving.
