Summarize the following court judgment. ivil Appeal No. 3447 of 1990. From the Judgment and Order dated 26.4.1990 of the Madhya Pradesh High Court in Misc. Petition No. 4059 of 1989. Rajinder Sachar	 Vijay Gupta	 Vivek Gambhir	 S.K. Gamb hir and Surinder Karnail for the Appellant. B.S. Banthia	 S.S. Khanduja and S.K. Agnihotri for the Respondents. The Judgment of the Court was delivered by RANGANATHAN	 J. Getting an admission into a professional course has become so difficult and competitive of late that litigation instituted by disappointed candidates has become a regular feature. 431 This appeal	 arising out of such a context	 throws up for consideration certain aspects which call for a difficult exercise in balancing equities. We	 therefore	 proceed to discuss the facts and issues at some length. The appellant Dr. Ku. Nilolaf Insaf and respondent No. 4	 Dr. Devraj Jain	 were competitors for a single seat in the Master 's Degree (M.D.) course in Radiology at Gandhi Medical College	 Bhopal. The appellant got admission to this seat in preference to Dr. Jain because she had obtained average marks of 59.60 per cent in the examinations of the M.B.B.S. course whereas Dr. Jain had obtained only 58.50 per cent. Dr. Jain successfully challenged the admission granted to the appellant in preference to himself in a writ petition in the Madhya Pradesh High Court. Dr. Insaf	 who has for feited her admission in consequence of the judgment of the High Court	 has filed the present appeal. In order to appreciate the circumstances in which the admission granted to the appellant was quashed by the High Court	 though she had admittedly got a higher percentage of marks than Dr. Jain	 it is necessary to set out a few fur ther facts. Dr. Jain and Dr. Insaf both completed their M.B.B.S. course in the years 1983 87. However	 while Dr. Jain had been admitted into and completed that course in the Gandhi Medical College	 Bhopal	 the appellant had initially joined her M.B.B.S. course in the M.S. Ramayya Medical College	 Bangalore	 wrote the first examination and complet ed the first year of the M.B.B.S. course there. Thereafter	 in August 1984	 she made an application for her transfer to the Gandhi Medical College	 Bhopal. Her request was granted by the Gandhi Medical College with the approval of the State of Madhya Pradesh and with "no objection" from the Ramayya Medical College. Thereafter she sat in the second and third examinations pertaining to the MBBS degree along with Dr. Jain and completed her MBBS course along with Dr. Jain in 1987 from the Gandhi Medical College	 Bhopal. Thereafter	 both of them cleared their internship of one year and also joined a house job in Radiology in the same college and completed the same in August 1989. It was at this stage that both of them applied for being admitted to the M.D. course with the result already set out. As already mentioned	 it is not in dispute that	 if the total number of marks obtained by the two contestants in all the examinations of the M.B.B.S. degree are taken and re duced to an "effective" percentage and a common maximum as per the rules	 Dr. Nilofar does get a higher percentage of marks than the respondent. In fact	 we 432 find from the papers filed before us that another candidate	 Dr. Km. Indu Fotedar	 had obtained a percentage of 59.04 which was also higher than the percentage obtained by Dr. Jain. However	 she is no longer in the race for a seat in M.D. (Radiology) as she appears to have joined the M.D. course in medicine that was offered to her. Thus it was that the Radiology seat went to Dr. Insaf. Dr. Jain 's challenge to the admission granted to the appellant cannot be a direct one as the latter had clearly secured higher percentage of marks than himself in the M.B.B.S. examinations. He	 therefore	 attacks her candida ture for the M.D. course on other grounds which may be described as collateral or indirect. According to him	 the transfer of the appellant from the Bangalore Medical College to the Bhopal Medical College was itself invalid and he urges that	 since the very admission of the appellant to the M.B.B.S. degree in the Bhopal College was invalid	 she could not at all have been considered for admission to the M.D. course which was available only to the institutional candi dates. The grounds on which the transfer of the appellant from Bangalore to Bhopal is challenged by Dr. Jain are: (a) The appellant had appeared in the pre medical test for admission to medical colleges in Madhya Pradesh. It is not known whether she passed the test or did not get a sufficiently high rank but the fact is that she did not get admission in any of the medical colleges in Madhya Pradesh. To overcome this difficulty	 she joined the Bangalore Medical College (the admission to which did not perhaps require qualification in a pre medical examination) by paying a capitation fee. She has thus circum vented the requirement of a pre medical test by getting admitted first at Bangalore and then getting a transfer to Bhopal; (b) According to the rules	 no transfer of a candidate to a medical college in Madhya Pradesh was permissible to students of medical colleges outside the State who had secured admission in a college after paying a capita tion fee	 development fee or 'donation in any form. As the appellant had obtained admission in the Bangalore college by paying a capita tion fee	 her application for transfer to the Bhopal Medical College could not and ought not to have been entertained; (c) The rules also require	 where a person makes an application for a transfer to a medical college in Madhya Pradesh	 that the application should state the grounds on which he got admission 433 in a medical college of another State and whether he had appeared for a pre medical test or similar examination of. that State. The appellant 's application for transfer did not contain any reference to this crucial aspect which was fundamental to a valid transfer to the college in Madhya Pradesh; (d) Even assuming that the transfer itself was not bad	 a comparison between the marks ob tained by the appellant and those obtained by the respondent was not a fair or proper one. The appellant had appeared for one examination at Bangalore and two examinations at Bhopal whereas Dr. Jain had appeared for all the three examinations at Bhopal/At Bangalore	 for the first year	 the appellant had three papers whereas in the Bhopal college there were only two papers in the first year. Having regard to the disparity in the syllabus	 the subjects for the examination	 the standards of valua tion and quality of teaching the comparison between himself and the appellant was not valid. If at all a comparison had to be made	 it should have been made by excluding the marks got by both in the first examination and taking into account Only the marks obtained by them in the other two examinations which were common to both. The above contentions found favour with the High Court quashed the admission of the appellant and directed Dr. Jain to be admitted to that seat. Hence the present appeal. In our opinion	 contentions (a) and (d) cannot stand by themselves and rest	 for their validity	 on contentions (b) and (c). While it is true that the appellant does not appear to have qualified in the premedical test for admission to colleges in Madhya Pradesh	 it cannot be said that she has circumvented the rules by first getting admitted to the Bangalore college and then seeking a transfer to Bhopal; that course	 if permissible under the rules	 was unobjec tionable. So also	 the last contention by itself has no force. It is well known that	 in these competitive days	 students are not able to get admission	 in the first in stance	 in an institution at their own place and have	 very often	 to seek admission elsewhere initially and then try to get a transfer back. This is also envisaged by the rules which permit the transfer of a student only after the first year course is completed. In such cases	 if a valid transfer is made	 the position is as if the candidate has completed the course in the second place and the rules (the validity of which are not in issue) permit a comparison of the aver age of marks obtained by the candidates in all the examina tions after reducing them as a 434 percentage of a uniform maximum. There can	 therefore	 be no doubt that such transfers and comparisons can be valid and permissible. The real question	 therefore	 is whether there has been a valid transfer on the facts of the present case. An annexure has been filed before us it was also before the High Court which purports to set out the "rules for transfer of the students from other medical colleges to Madhya Pradesh State medical colleges". Though the High Court and the parties before it proceeded on the basis that these were "rules" governing transfer	 there has been some controversy before us on this to which we shall advert later. The following rules are relevant for our present purpose: 1. The applications from students for transfer from Medical Colleges outside the State and studying in 1st M.B.B.S. (Pre Clinical block) will not be considered. Applications of those candidates who have cleared the 1st M.B.B.S. examination of the university in Anatomy & Physiology (including Biochemistry) and are studying in higher classes will be considered provided the Col lege in which he was studying was a Medical Council of India approved College. Applications of only those will be consid ered who satisfy the following conditions in accordance with the premedical examination rules of Madhya Pradesh (a) possessed minimum qualification for ap pearing in the pre medical examination at the time of admission. (b) is a bona fide resident of Madhya Pradesh as per rules of Pre medical Examination of M.P. (c) was within the prescribed age limit as per rules of Premedical Examination of Madhya Pradesh at the time of admission. Government would consider relaxation of rules in respect of those candidates who are married to a Government Servant employed in the Madhya Pradesh State. Applications of those candidates for trans fer from 435 Medical Colleges outside the State will not be considered who have secured admission in a College after paying capitation	 development fee or donation in any form. Application should also state the grounds on which he got admission in a Medical College of another State and whether he had appeared for pre medical test or similar examination of that State. 9. The appellant will submit a 'No Objec tion ' Certificate of the concerned Medical College and the University where he was study ing before his transfer. The applicant will submit his applications with all the required information first to the Dean	 Medical College where he wants to be transferred and the application will then be routed through the Chairman	 Pre Medical Examination Board to Government for final orders. On the basis of these rules	 the objec tions to the transfer raised on behalf of Dr. Jain may now be considered: (a) A submission was made that the Bangalore college is not an approved medical college (vide rule 2 above) but this is not substanti ated. The document relied upon in support of this contention is only a list of medical colleges in India published by the Health Ministry of the Central Government. There is no mention in it that only these colleges and none else have been approved by the All India Medical Council. Also	 the list does not bear a date. It appears to be an old one and does not refer to any college recognised after 1979. There is nothing to show that the Banga lore medical college was established before that. That apart	 it appears that the Banga lore college is affiliated to the Bangalore University	 and there is no reason to believe that it was not an approved medical college. (b) The objection that the transfer is bad because the appellant had not qualified in a pre medical test	 conducted either in Madhya Pradesh or in Bangalore	 does not appear to be well founded. While the rules no doubt contain a reference to premedical tests	 rules 3	 5 and 13 make it clear that the passing of a pre medical test is not a pre requisite for a transfer. No doubt rule 4 requires that the application for transfer should say whether the applicant had appeared for a pre medical or similar 436 test in the State from which a transfer is sought. The omission of the appellant in the present case to mention this in her applica tion may be a defect but	 in the absence of any clear rule to the effect that a pass in a pre medical test is an essential condition for transfer	 it cannot be treated as a vital defect vitiating the transfer. (c) There is	 however	 force in the contention that the transfer in the present case was violative of the first part of rule 4. This clearly precludes the consideration of an application for transfer from a person who had gained admission to a medical college on payment of a capitation fee	 development fee or donation. Neither the appellant nor the State contradicted Dr. Jain 's averment in the writ petition that the appellant had secured admission in the Bangalore college only on the basis of such payment. There is	 therefore	 an infringement of rule 4 atleast in part and we shall proceed to consider the effect of the same. But before we proceed to do so	 we should like to digress a little to make some general observations. From the facts stated earlier	 it is not clear how	 in the face of the specific provisions contained in the rules	 the appellant 's transfer was considered and sanctioned	 particularly when the application had to be scrutinised by a number of authorities: the Bhopal medical college	 the Chairman of the Pre medical Board referred to in rule 13	 the University of Bhopal and the State Government. It is difficult to believe that they were not conscious that the limitations imposed by the rules operated in this case. The application of the appellant (a copy of which has been placed before us) contained a bare and simple request for transfer and nothing more and the authorities did not even care to call for the details required under the rules before taking a decision. The respondent has alleged that this was done by reason of the influence exerted by the appellant 's father but this is not substantiated. All that has been brought out is that the appellant is a resident of Bhopal and her father is a doctor practising at Bhopal. In the circumstances we think that the authorities must have acted bona fide on considerations of sympathy towards	 and the hardship of	 the appellant in pursuing her course of study for a number of years at distant Bangalore. They must have thought that their decision would only help the appellant and harm no one. But the facts of the present case show how even well meant decisions	 which seem innocuous at the time they are taken	 can rebound in the long run and affect the interests of others in manner that could not have been even conceived of earlier. It is	 437 therefore	 necessary to emphasise that	 in matters of this type	 the authorities should carefully and strictly apply the relevant rules. Now reverting to the question as to the impact of this infringement of the rules on the situation in the present case	 Sri Sachar	 appearing for the appellant	 puts forward two aspects for consideration. In the first place	 he sub mits that the rules relied upon for the respondent are merely internal guidelines or instructions not having the force of law and that a deviation therefrom here or there would not affect the validity of the order accepting the application for transfer. Sri Sachar may be right in saying this but unfortunately	 both parties and the High Court have proceeded on the basis that there were "rules" i.e. some instruments having statutory force. No material has been placed before us either to support or repel this assumption and so we will not be justified in treating them to be otherwise. However	 we think that	 even if they are viewed as "rules" they should not be treated as rigid	 inflexible and mandatory	 having in mind the context and purpose in which they are made. These are rules setting out circum stances in which the application for transfer will be grant ed and deal with a matter primarily concerning the applicant and the authorities. The validity of an order for transfer may be challenged contemporaneously by a third party whose claim for admission or transfer is superseded by such order but cannot be al lowed to be challenged by a third party because he finds	 in retrospect	 at a future point of time	 that it has affected his interests as a result of subsequent events. We would	 therefore	 hold that the order of the State of Madhya Pra desh permitting the transfer of the appellant cannot be struck down as void. There has been some irregularity but	 in the circumstances in which it was passed	 it was one within the competence of the State Government. The second answer	 furnished on behalf of the appellant to Dr. Jain 's challenge is that Dr. Jain was aware	 even as early as 1987	 that in the order of merit of M.B.B.S. candi dates the appellant ranked higher than the respondent. Apart from the fact that this was just a matter of arithmetic	 an "order of merit" had indeed been published by the University at the time the medical graduates of 1987 were being consid ered for house jobs. Reference is made in this context to a chart entitled "Merit list for the selection of House Offi cers	 Gandhi Medical College	 Bhopal	 for the year 1988" placed at p. 68 of the paper book before us This list is incomplete but it contains the names	 in order of merit	 of 58 students who had completed M.B.B.S. in 1987 438 who had	 apparently	 applied for house jobs in the college. It sets out their aggregate marks in the M.B.B.S. examina tions with certain adjustments and also the effective per centage thereof. The appellant 's percentage is shown as 59.60 and his rank as 37; Dr. Indu Fotedar is at 44 with a percentage of 59.04; and Dr. Jain is No. 49 with a percent age of 58.50 Sri Sachar invites our attention to the "Rules for Postgraduation (M.D./M.S. course) in clinical	 para clinical and nonclinical disciplines	 in medical colleges in Madhya Pradesh". These rules provide a scheme whereby (a) the marks obtained by candidates in the M.B.B.S. examina tions (sometimes at different colleges and universities which have different maxima for the examinations) are to be standardised to a common maximum; (b) adjusted by giving certain penalty marks (for example	 where a candidate has made extra attempts in any examination) and bonus marks (where he has some special distinctions in academics or extra curricular activities: for example	 distinction in a subject or National Cadet Corps certificates); and (c) determining the "effective marks" and their percentage. The process of selection of merit candidates for the post gradu ate course is outlined in rules 8.1 to 8.3. They read thus: "8.1 Merit candidates in clinical subjects shall be selected from out of those who are completing their house jobs within that ca lender year. 8.2 Candidates under 8.1 shall be selected by the Dean of the Medical College	 strictly on the basis of merit from amongst the students passing from that college	 on the recommenda tion of the college and Hospital Council or the P.G. Committee of the college. 8.3 The merit list of candidates under 8.1 and 8.2 would be prepared by each Dean of the College every year and notified on the College Notice Board. Any objection or representation received within 10 days of notification would be considered by the Dean of the College who shall make modifications	 if necessary	 after placing the objection or representation before the College and Hospital Council or P.G. Committee. " On the strength of these rules	 Sri Sachar contends that the respondent	 not having preferred objections to the merit list referred to earlier	 is now estopped from challenging the merit list. 439 We find that there is a good deal of confusion about the relevant facts in this regard. In the High Court	 the re spondent 's case was that he had duly filed his objections to the merit list of 1989 in July 1989 and well within time. The list that is relied upon by him is a list published by the Dean which bears the heading "Particulars of the candi dates who have applied for registration in M.D. Radiology for the year 1989" placed at page 49 of the paper book. It contains 9 names (including Drs. Insaf	 Jain and Fotedar) and the details of their period of study and internship. The last two columns are headed "Effective Marks" and "Effective Percentage". They are not	 however	 arranged in order of merit but are arranged on a different basis. The first four names are of candidates who had applied for the M.D. course in Radiology	 whereas the others had applied also for admis sion to M.D. courses in other subjects. It is on the basis of this list apparently	 that the selections were made and	 in his petition for special leave before us	 the appellant also admitted this position. Sri Sachar	 however	 contends	 that the earlier list produced by him (p. 68) is the merit list referred to in the rules and not this one which does not even purport to be a "merit list". The merit list of 1988 (p. 68) was clearly one prepared in the context of selection for house jobs in 1988. The rules regulating admissions for that purpose have not been placed before us. We can only guess from the contents and columns in the list that they apparently run on the same lines as the rules for admission for M.D. If this be treated as the merit list referred to in rule 8.3	 of the relevant rules	 Dr. Jain is clearly precluded from challenging it after one year. But rule 8.3 refers to merit list for selec tion of candidates for the diploma course being published every year. None of the parties including the college au thorities have been able to clarify whether (apart from the list at p. 49 of the paper book) any "merit list" for the year 1989 in respect of admission to M.D. courses	 on the pattern of the list at p. 68	 had at all been published by the Dean of the college. In this context	 we should ' point out that the list earlier published (p. 68) contained all the relevant details for preparation of such a merit list. There is nothing before us to show that the procedure for adjustment	 standardisation and averaging were not the same for preparing a merit list for selection of house officers as for the selection of candidates to the M.D. courses outlined in rule 8.5 (and this appears to be so from the adjustment columns in the list at p. 68). The only differ ence is that this list is restricted only to the nine candi dates seeking admission to the M.D. course in radiology. Apparently	 having regard to the small number of applicants for the course in question	 the authorities merely. 440 prepared a short list containing the relevant extracts regarding effective marks and percentage from the earlier list without calling it a merit list and made the selec tions. In the circumstances	 we think that there can be no practical or legal difficulty in treating the list at p. 49 as the relevant merit list for the present purpose. Learned counsel for Dr. Jain is	 therefore	 correct in saying that	 in this view	 he could and did lodge his objections within the time specified in rule 8.3 and he cannot be precluded from contesting the correctness or validity of the list on the grounds of delay. On strictly legal considerations	 therefore	 the respondent cannot be shut out from raising his objections at this stage. But	 it seems to us	 questions of this nature cannot be decided on considerations of pure law. Granting that it is open to Dr. Jain to challenge the merit list	 one has to examine whether there are any limits to the scope of such challenge on grounds	 if not of law	 of justice and equity. Of course	 he can challenge the correctness of the order of merit	 he can challenge any errors in the marks taken into account or the adjustments made thereto	 and he can even challenge the eligibility of any of the candidates for consideration. But there are abvious limitations to such challenge. For example	 it would seem difficult to say that one can challenge the correctness of the marks that one of the other candidates has obtained in the examinations and call for the revaluation of some or all of his papers or to permit a contention that one of the candidates has not been properly awarded the M.B.B.S. degree and that	 therefore	 his application should be ignored. Their having obtained the marks noted in the list or a degree of a university or secured a transfer are actual events that have happened. There may have been some irregularity at some earlier stage but it does not go to the root of the matter so as to render the qualification void abinitio capable of being ignored	 without anything more	 at any time for any purpose. The position may be different where a person is claiming under a bogus degree. The appellant has obtained the degree after a regular course; the only grievance is that she should not have been permitted to do part of it in a particular col lege. The legality or validity of such qualifications must be directly challenged and got set aside in independent proceedings. To permit a collateral attack on them in other proceedings	 as here	 will be beset with problems and com plications of a far reaching magnitude. For obvious reasons	 limitations have to be imposed on the grounds available for such challenge. The need for such circumspection will be better appreciated if another situation of a similar nature is considered. Suppose the competition between the two present contestants had arisen	 441 not	 as it has	 just two years after the M.B.B.S. degree	 but	 say	 fifteen years later	 when they both apply for a post in a hospital or Government open to M.B.B.S. graduates. If	 in that situation	 it should be contended for Dr. Jain that the appellant cannot be considered for the post because her transfer to the Bhopal medical college was bad and	 consequently	 that the M.B.B.S degree obtained by her was not valid	 we think the answer to the contention must pat ently be in the negative. The need to avoid disturbing settled issues which affect the life and career of an indi vidual after a lapse of time or after the interposition of further events	 as a result of which he has rightly de veloped a sense of security	 has been emphasised by this Court in Mudgal vs Singh	 1 relying on the earlier decisions in Makashi vs Menon	 ; and Malcolm Lawrence Cecil D 'Souza vs Union	 [1975] Supp SCR 409. What should be a reasonable period beyond which	 or the intervening developments because of which	 such challenge cannot be permitted must depend on the facts and circum stances of each case. In the present case	 there are valid considerations why Dr. Jain should not be allowed to challenge the merit list at this point of time. We have referred earlier to the plea of Dr. Jain that he has challenged the merit list of 1989 within the period of time mentioned in the rules. Technical ly	 he is right	 as we have already held. But if we look at the position more closely	 we find that the precedence of the appellant over Dr. Jain crystallised as soon as the M.B.B.S. results were published. We do not know whether any merit list of the results of the examination were published or not at that time but it cannot be that Dr. Jain was not aware that the appellant had got higher percentage of marks than himself. At any rate	 this became clear when the merit list was published for the house jobs in August 1988. It is true that the place accorded to the appellant in that list did not prejudice Dr. Jain in his selection for the house job. Still	 the rules of the university make it clear that the aggregate and average marks in the M.B.B.S. course would also be material for admission to the M.D. course. The merit list of 1989 is nothing but a reproduction of the merit list of 1988 confined to a narrower group of students of the same batch. The latter did show the appellant to have obtained more marks than Dr. Jain and	 in this sense	 was adverse to his interests. The omission of Dr. Jain to challenge the correctness of the list then lulled the appellant into a sense of security that the merit list was acceptable to all. We	 therefore	 think that Dr. Jain should be barred	 on equitable considerations	 from challenging the order of merit at the present stage. Another important consideration which prevents us from giving 442 any relief to Dr. Jain even if we accept all his conten tions is this. The M.D. course	 admission to which is the bone of controversy	 started in August 1989 and is coming to a close shortly. Though the appellant lost in the High Court	 she was permitted by this Court though	 obviously	 subject to the result of this appeal to continue attending the classes for M.D. in Radiology. Now she has almost com pleted her course and	 to deprive her of her seat at this stage	 apart from irretrievably harming her	 will not bene fit Dr. Jain who cannot now be admitted against the M.D. seat of 1989. This again is a development which militates against the grant of any relief to Dr. Jain. Before we conclude	 we should like to touch upon one more aspect. The course of events narrated above will show that Dr. Jain has been the victim	 partly	 of a lapse on the part of the medical college authorities in properly applying the rules governing transfer and	 partly	 of courts ' delay in disposing of his writ petition and the present appeal. In the course of the hearing	 therefore	 we were tempted to consider whether we should give some relief to Dr. Jain by directing the authorities to consider his case for admission to the M.D. course atleast this year. On careful thought	 however	 we find it difficult to make any specific direc tions or recommendations for a number of reasons. In the first place	 we are told that Dr. Jain has	 in the meantime	 undergone and completed a diploma course in Radiology and	 in terms of a rule recently promulgated	 is not eligible to apply for the M.D. course for another three years	 even if he is interested to do so. Secondly	 as noted already	 the rules permit admission in M.D. in any year only to candi dates who have finished their house jobs in that year and	 Dr. Jain having completed his house job in 1989	 may not be eligible to be considered for admission this year. Thirdly	 if any direction of the above nature is given by us	 it will operate to the prejudice of some other candidate who is eligible for admission to that course in the normal course. Fourthly	 it would not also have been possible for us even if we had come to the conclusion that Dr. Jain and not the appellant should have been admitted in 1989 to direct the University to carry forward that vacancy and grant him admission to it now. We therefore refrain from giving any directions to the authorities in the matter as had been mooted in the course of the hearing. For the reasons above mentioned	 we have come to the conclusion that the appeal should be allowed and the appel lant 's admission to the M.D. Radiology course 1989 91 should be upheld. We direct accordingly. No costs. Y.L. Appeal allowed.

The appellant and Dr. Jain	 respondent No. 4	 completed their M.B.B.S. course in the years 1983 87. from Gandhi Medical College	 Bhopal. While Dr. Jain had been admitted into that course in the Gandhi Medical College	 Bhopal after he had passed the entrance test	 the appellant first sought admission to M.B.B.S. course in the M.S. Ramayya Medical College	 Bangalore	 after paying the capitation fee and after completing the first year of the course in that Col lege she got herself transferred in 1984 to the Gandhi Medical College	 Bhopal	 with the approval of the State Government and with no objection from the Ramayya College	 Bangalore. After passing M.B.B.S. both of them cleared their internship of one year and also joined a house job in Radiology in the same college and completed the same in August 1989. Both of them then applied for a single seat in the Master 's Degree (M.D.) course in Radiology at Gandhi Medical College	 Bhopal. The appellant having secured higher marks got admission to this seat in preference to Dr. Jain. Dr. Jain	 thereupon	 challenged the admission of the appellant by means of a writ petition before the High Court on the ground inter alia that the transfer of the appellant from the Bangalore Medical College to the Bhopal Medical College was itself invalid and since the very admission of the appellant to the M.B.B.S. course degree in the Bhopal College was invalid	 she could not at all have been considered for admission to the M.D. course which was available only to the institutional candidates. The High Court allowed the writ petition	 quashed the admission of the appellant and directed that Dr. Jain	 be admitted to that seat. Hence this appeal by the appellant. Allowing the appeal	 this Court	 HELD: The validity of an order for transfer may be chal lenged 430 contemperaneonsly by a third party whose claim for admission or transfer is superseded by such order but cannot be al lowed to be challenged by a third party because he finds	 in retrospect	 at a future point of time	 that it has affected his interests as a result of subsequent events. [437E] The order of the State of Madhya Pradesh permitting the transfer of the appellant cannot be struck down as void. There has been some irregularity hut	 in the circumstances in which it was passed	 it was one within the competence of the State Government. [437F] There is the need to avoid disturbing settled issues which affect the life and career of an individual after a lapse of time or after the interposition of further events	 as a result of which he has rightly developed a sense of security. [441B] In the instant case	 the merit list of 1989 is nothing but a reproduction of the merit list of 1988 confined to a narrower group of students of the same hatch. The latter did show the appellant to have obtained more marks than Dr. Jain and	 in this sense	 was adverse to his interests. The omis sion of Dr. Jain to challenge the correctness of the list then lulled the appellant into a sense of security that the merit list was acceptable to all. Dr. Jain	 should therefore be barred	 on equitable consideration from challenging the order of merit at the present stage. [441G]
