Summarize the following court judgment. Appeal No. 871 of 1974. (Appeal by Special Leave from the Judgment and Order dated 3 4 1973 of the Allahabad High Court in Civil Misc. Writ Petition No. 2128/73). Yogeshwar Prasad and Miss Rani Arora for M/S Bagga for the Appellant. G.N. Dikshit and O.P. Ran	 for Respondents No. 1 and 2. The Judgment of the Court was delivered by BHAGWATI	 J. This appeal by special leave is directed against an order passed by the High Court of Allahabad rejecting a writ petition filed by the appellant challenging the validity of an order of the State Transport Appellate Tribunal confirming an order of the Regional Transport Authority rejecting the application of the appellant for renewal of his stage carriage permit for the route Nagina Jaspur. The route Nagina Jaspur lies within the jurisdiction of the Regional Transport Authority Bareilly. The appellant and his brother Mohd. Ashfaq held a stage carriage permit for this route for some years and it was due to expire on 1st July	 1971. Before the expiration of the period of permit	 however	 a scheme was prepared and published by the State Transport Undertaking under Section 68C of the (hereinafter referred to as 'the Act ') and this scheme covered the route Nagina Jaspur. The publication of this scheme did not affect the validity of the permit of the appellant and Mohd. Ashfaq and they continued to ply their motor vehicles on the route Nagina Jaspur on the strength of the permit. During the currency of the permit	 several amendments of a far reaching charac ter were made in the Act by Act 56 of 1969 and sub sections (1A) to (1D) were introduced in Section 68F after sub sec tion (1). These sub sections are material and they may be reproduced as follows: "68F(1A) Where any scheme has been published by a State Transport Undertaking under section 68C	 that Undertaking may apply for a temporary permit. in respect of any 565 area or route or portion thereof specified in the said scheme	 for the period intervening between the date of publication of the scheme and the date of publication of the approved or modified scheme	 and where such application is made	 the State Transport Authority or the Regional Trans port Authority	 as the case may be	 shall	 if it is satis fied that it is necessary to increase	 in the public inter est	 the number of vehicles operating in such area or route or portion thereof	 issue the temporary permit prayed for by the State Transport Undertaking. (1B) A temporary permit issued in pursuance of the provisions of sub section (1A) shall be effective	 (i) if the scheme is published under sub section (3) of section 68D	 until the grant of the permit to the State Transport Undertaking under sub section (1)	 or (ii) if the scheme is not published under sub section (3) of section 68D	 until the expiration of the one week from the date on which the order under sub section (2) of section 68D is made. (1C) If no application for a temporary permit is made under sub section (1A)	 the State Transport Authority or the Regional Transport Authority	 as the case may be	 may grant	 subject to such conditions as it may think fit	 temporary permit to any person in respect of the area or route or portion thereof specified in the scheme and the permit so granted shall cease to be effec tive on the issue of a permit to the State Trans port Undertaking in respect of that area or route or portion thereof. (1D) Save as otherwise provided in sub section (1A) of sub section (1C)	 no permit shall be granted or renewed during the period intervening between the date of publication	 under section 68C of any scheme and the date of publication of the approved or modified scheme	 in favour of any person for any class of road transport service in relation to an area or route or portion thereof covered by such scheme: Provided that where the period of operation of a permit in relation to any area	 route or portion thereof specified in a scheme published under section 68C expires after such publication	 such permit may be renewed for a limited peri od	 but the permit so renewed shall cease to be effective on the publication of the scheme under sub section (3) of section 68D." Since the permit of the appellant and Mohd. Ashfaq was going to expire on 1st July	 1971	 the appellant made an applica tion for renewal of the permit under the proviso to sub section (1D) of Section 68F and submitted the application to the Regional Transport Authority on 22nd March	 1971. When the application came up for hearing before the 566 Regional Transport Authority	 there was admittedly no objec tor against it	 but the Regional Transport Authority took the view that under the proviso to sub section (2) of Sec tion 58 an application for renewal of a permit is required to be made not less than 120 days before the date of expiry of the permit and even if there is delay in making the application	 it can be condoned under sub section (3) of Section 58 but only if it is a delay of not more than 15 days and since in the present case the application for renewal of the permit was made by the appellant on 22nd March	 1971	 it was late by 18 days and hence the delay was not capable of being condoned and in this view	 the Regional Transport Authority by an order dated 28th March	 1973 rejected the application for renewal of the permit as time barred. The appellant preferred an appeal to the State Transport Appellate Tribunal and in the appeal the appellant chal lenged the correctness of the order of the Regional Trans port Authority. The State Transport Appellate Tribunal	 however	 agreed with the view taken by the Regional Transport Authority and held that in view of the specific prohibition contained in sub section (3) read with the proviso to subsection (2) of Section 58 it was not competent to the Regional Transport Authority to condone the delay in making of the application for renewal of the permit	 since the delay was of more than 15 days. The State Transport Appellate Tribunal also observed that in any event the material produced before the Regional Transport Authority did not make out any sufficient cause for not making the application for renewal of the permit within time and hence even if there was no statutory bar against condonation of delay of more than 15 days	 this was not a fit case in which the delay should be condoned. The State Transport Appellate Tribunal accordingly confirmed the order of the Regional Transport Authority. This led to the filing of a writ petition by the appel lant in the High Court of Allahabad. The High Court sum marily rejected the writ petition stating that no ground had been made out for exercise of the extraordinary juris diction of the High Court under Article 226 of the Constitu tion. Hence the appellant brought the present appeal with special leave obtained from this Court. Two contentions were urged on behalf of the appellant in support of the appeal. The first contention was that the time limit specified in the proviso to sub section (2) of section 58 was not applicable in case of an application for renewal of a permit under the proviso to subsection (10) of section 68F and the Regional Transport Authority was not entitled to reject the application of the appellant for renewal of his permit as time barred. It has also been contended in the alternative that even if the time limit set out in to proviso to sub section (2) of section 58 was applicable	 sub section (3) extended such time limit by fifteen days and even if thereafter there was any delay beyond the extended time limit	 it could be condoned by the Regional Transport Authority for sufficient cause by reason of section 5 read with section 29	 subsection (2) of the . The second contention Which followed on the acceptance of the last contention was that the appellant had sufficient cause for not preferring the appli cation for renewal 567 of his permit within the extended time limit and hence the Regional Transport Authority should have condoned the delay and entertained the application on merits. The validity of both these contentions was disputed on behalf of respondents 1 and 2 and it was urged that the time limit specified in the proviso to sub section (2) of section 58 was applicable in the present case and the only delay which could be con doned was a delay of 15 days and not more and in any event	 there was no sufficient cause made out by the appellant for not making the application for renewal within time and hence the application for renewal was rightly rejected as time barred. We shall proceed to consider the merits of these rival contentions. The first question which arises for consideration on these contentions is as to whether the time limit pre scribed by the proviso to subsection (2) of section 58 applies in case of an application for renewal of a permit under the proviso to sub section (10) of section 68F. The argument of the appellant was that Chapter IVA which contains	 inter alia	 section 68F	 is a self contained Chapter and nothing in the other provisions of the Act applies to proceedings under that Chapter and hence neither the procedure under section 57 nor the time limit specified in the proviso 10 sub section (2) of section 58 has any application to an application for renewal of a permit under the proviso to sub section (10) of section 68 F. This argument is	 in our opinion	 manifestly wrong. The scheme of Chapter IVA is clear and it does not exclude the applica bility of the provisions contained in section 57 and the proviso to sub section (2) of section 68. Chapter IVA contains a fasciculus of sections commencing from section 68A and ending with section 68 B. Section 68 A defines certain expressions used in Chapter IVA. Section 68 B gives overriding effect to the provisions contained in Chapter IVA by saying that these provisions shall have effect	 notwith standing anything inconsistent therewith contained in Chapter IV or in any other law for the time being in force. Section 68 C provides that where any State Transport Undertaking is of opinion that for the purpose of provid ing an efficient	 adequate	 economical and properly co ordinated road transport service	 it is necessary in the public interest that road transport service in relation to any route should be run and operated by the State Transport Undertaking	 a scheme may be prepared by the S1ate Transport Undertaking giving particulars of the nature of the services proposed to be rendered	 the route proposed to be covered and other prescribed particulars and such scheme shall be duly published. Certain categories of persons are empow ered by section 68 D sub section (1) to file objections against the scheme published under sect ion 68 C and the State Government may then	 after considering such objections and hearing the parties	 approve or modify the scheme under sub section (2) of section 68 D. Section 68 D sub section (3) provides that the scheme as approved or modified under sub section (2) shall be Published in the Official Gazette and it shall thereupon become final and shall be called the approved scheme and the routes to which it relates shall be called the notified routes. Section 68 E provides for concellation or modification of the scheme. Then follows section 68 F which is material for our purpose. Sub section (1) of that section provides for issue of a permit to the State Transport Undertaking in respect of a notified route 568 after publication of an approved scheme. But what is to happen during the period between the publication of a scheme under section 68 C and the publication of the ap proved scheme under sub section (3) of section 68 D ? That is taken care of by sub sections (1A) to (1 D) of section 68F. Sub section (1 A) provides that for this intervening period	 the State Transport Undertaking may apply for a temporary permit in respect of a route specified in the scheme and where such application is made	 the Regional Transport Authority shall	 if it is satisfied that it is necessary to increase	 in the public interest	 the number of vehicles operating on such route	 issue the temporary permit prayed for by the State Transport Undertaking. What shall be the duration of such temporary permit is laid down in sub section (1 B). Sub section (1 C) deals with the situation where no application for a temporary permit is made by the State Transport Undertaking and it says that in such a case	 the Regional Transport Authority may grant temporary permit to any person in respect of a route speci fied in the scheme. Sub section (1 D) imposes a prohibi tion that "save as otherwise provided in sub section (1 A) and sub section (1 C)	 no permit shall be granted or renewed during the period intervening between the date of publica tion under section 68 C of any scheme and the date of publi cation of the approved or modified scheme	 in favour of any person" in relation to a route covered by such scheme	 but this is subject to a proviso that where the period of operation of a permit in relation to any route "specified in a scheme published under section 68 C expires after such publication	 such permit may be renewed for a limited period". It will	 therefore	 be seen that where a scheme is published under section 68 C	 no permit in respect of a route specified in the scheme can be granted or renewed during the intervening period between the publication of the scheme under section 68 C and the publication of the approved scheme	 except a temporary permit to the State Transport Undertaking under sub section (1 A) or failing that	 a temporary permit to any other person under sub section (1 C)	 with this qualification that an existing permit can be renewed for a limited period. The holder of an existing permit would obviously exnecessitas have to make an application	 if he wants renewal of his permit and the application for renewal would be considered by the Regional Transport Authority. The question is: can this application for renewal be made at any time and when it is made	 what procedure would govern it. Section 57 lays down the procedure to be followed in dealing with an application got grant of a permit and by reason of section 58 sub sec tion (2)	 that procedure is applicable also in relation to an application for renewal of a permit. There is also a time limit laid down in the proviso to sub_section (2) of section 58 which says	 in so far as relevant	 that an application for renewal of a .permit shall be made not less than 120 days before the date of expiry of the permit. These provi sions in section 57 and the proviso to sub section (2) of section 58 on their plain language apply to every applica tion for renewal of a permit and it is indeed difficult to see what difference there is between an application for renewal of a permit under the proviso to sub section (1 D) of section 68 F and any other application for renewal of a permit. An application for renewal of a permit under. the proviso to sub section (1 D) of section 68 F is as much an application for renewal as any other. It had to be special ly provided for in the 569 proviso to sub section (1 D) of section 68 F	 because sub section (1 D) imposes a prohibition on grant or renewal of permit during the intervening period between the publica tion of a scheme under section 68 C and the publication of the approved scheme and	 ii the proviso were not enacted	 renewal of an existing permit expiring after the publication of the scheme under section 68 C would have been barred. This	 the Legislature did not want and hence the proviso was introduced permitting renewal of an existing permit though for a limited period	 despite the general prohibition enact ed in sub section (1 D). This renewal was not intended to be sore6 special kind of renewal different from any other ordinary renewal of a permit. There is	 therefore	 no reason in principle why the provisions enacted in section 57 and the proviso to sub section (2) of section 58 should not apply in case of an application for renewal of a permit under the proviso to sub section (1 D) of section 68 F. If the procedure set out in section 57 does not apply in such a case	 there is no other procedure prescribed by the Act which can possibly be invoked and the result would be that them would be no procedure for dealing with such an applica tion. for renewal and in that event	 how would the objec tions be invited against the application for renewal and within what time and who would be entitled to be heard and when ? And equally if the time Limit specified in the proviso to sub section (2) of section 58 does not apply	 there would be no time limit for making such an application for renewal and it would be possible to make it any time	 even after the expiry of the period of the permit and the Regional Transport Authority would be bound to consider it. That surely could never have been the intention of the Legislature. Moreover	 it is implicit in the enactment of section 68 B that Chapter IV A is not a self contained Chapter to which the other provisions of the Act are inap plicable. If Chapter IVA were a self contained Code by itself	 there would have been no need to give overriding effect to the provisions in that Chapter as against the other provisions of the Act. Section 68 F	 sub section (3) also proceeds on the assumption that	 but for its enactment	 an order made by the Regional Transport Authority under sub section (1) or sub section (2) of section 68 F would have been appealable under section 64 and it was to ex clude the applicability of section 64 that sub section (3 ) of section 68 F was enacted. These two circumstances dearly point to the conclusion that the other provisions of the Act	 to the extent to which their language warrants	 apply in relation to proceedings under Chapter IVA	 save in so far as they may be	 expressly or by reason of repugnance or inconsistency	 overridden. We must	 therefore	 reject the first contention of the appellant which seeks to exclude the applicability of the proviso to sub section (2) of section 58 to an application for renewal of a permit under the proviso to subsection (1 D) of section 68 F. That takes us to the next question as to the applicabil ity of section 5 of the to an applica tion for renewal of a permit. It would be convenient at this state to refer to the provisions of subsections (2) and (3) of section 58	 which	 so far as material	 read as follows: "(2) A permit may be renewed on an application made 570 and disposed of as if it were an application for a permit: Provided that the application for the renew	d of a permit shall be made (a) in the case of a stage carriage permit or a public carrier 's permit	 not less than one hundred and twenty days before the date of its expiry; and (b) in any other case	 not less than sixty days before the date of its expiry: Provided further that	 other conditions being equal	 an application for renewal shall be given preference over new applications for permits. (3) Notwithstanding anything contained in the first proviso to sub section (2)	 the Regional Transport Authority may entertain an application for the renewal of a permit after the last date specified in the said proviso for the making of such an application	 if the application is made not more than fifteen days after the said last date and is accompanied by the prescribed fee. " The proviso to sub section (2) requires that an application for renewal of a permit should be made not less than 120 days before the date of expiry of the permit. But	 notwith standing this provision	 the Regional Transport Authority may	 under sub section (3)	 entertain an application for renewal of a permit after the last date specified in subsec tion (2)	 "if the application is made not more than 15 days after the said last date and is accompanied by the pre scribed fee. " Sub section (3) thus vests a discretion in the Regional Transport Authority to entertain an application for renewal of a permit even if it is beyond time	 but in that case the delay should not be of more than fifteen days. The word used in sub section (3) is "may" and not "shall" and the Regional Transport Authority is given a discretion to entertain 	m application for renewal of a permit even where it is beyond time	 though not more than 15 days. It may condone the delay or it may not	 depending on the circum stances of each case. The discretion is be exercised not on any arbitrary of fanciful grounds or whim or caprice of the Regional Transport Authority	 but it is to be a judicial discretion. It is true that the criterion which is to guide the Regional Transport Authority in the exercise of its discretion is not articulated in sub section (3)	 but it is implicit in every conferment of discretion on a judicial or quasi judicial authority that the discretion is to be exercised in a judicial manner on well settled legal prin ciples. would not be right to attribute to the Legislature an intention to confer unguided and unfettered discretion on the Regional Transport Authority which is quasi judicial authority. The discretion is obviously to be exercised where sufficient cause for not making the application for renewal within time is made out by the applicant. This 571 criterion can legitimately be imported from section 5 of the which contains an allied provision for condonation of delay where an application is made beyond time. It could never have been the intention of the Legis lature that even where there is no sufficient cause for delay in making an application for renewal	 the Regional Transport Authority should still be bound to entertain the application for renewal merely	 on the ground that the delay is of not more than 15 days. Sub section (3) enacts a provision for condonation of delay in making an application for renewal and not provision extending the time limit specified in the proviso to sub section (2) in all cases as a matter of course. If the intention of the Legislature were that in every case delay of not more than 15 days in making an application for renewal should be condoned as of course	 there was no need for a separate provision in sub section (3)	 but the Legislature could have very specified "one hundred and five days" instead of "one hundred and twenty days" in the proviso to sub section (2). It is	 therefore	 dear that sub section (3) of section 58 confers a discretion on the Regional Transport Authority to entertain an application for renewal when it is made beyond the time limit specified in the proviso to sub sec tion (2)	 but not more than 15 days late and the discretion is to be exercised in favour of entertaining the application for renewal when it is shown that there was sufficient cause for not making it in time. Now the question which arises is: does section 5 of the apply so as to empower the Regional Transport Authority	 for sufficient cause	 to entertain an application for renewal even where it is delayed by more than 15 days? Section 29	 sub section (2) of the makes section 5 applicable in the case of an application for renewal unless its applica bility can be said to be expressly excluded by any provision of the Act. The only provision of the Act sought to be pressed into service for this purpose was sub section (3). Does sub section (3) expressly exclude further extension of time under section 5 ? If it does	 then section 5 cannot be availed of by the appellant for condonation of the delay. Sub section (3) in so many terms says that the Regional Transport Authority may condone the delay in making of an application for renewal and entertain it on merits provided the delay is of not more than 15 days. This clearly means that if the application for renewal is beyond time by more than 15 days	 the Regional Transport Authority shall not be entitled to entertain it or in other words	 it shall have no power to condone the delay. There is thus an express provision in sub section (3) that delay in making an appli cation for renewal shall be condonable only if it is of not more than 15 days and that expressly excludes the applica bility of section 5 in cases where an application for renew al is delayed by more than 15 days. This provision may seem harsh	 but it has been deliberately and advisedly made because the question of renewal of a permit must obviously be decided before the expiration of the period of the permit and in view of the elaborate procedure set out in section 57 for dealing with an application for renewal	 a certain minimum period before the expira 5 1234SCI/76 572 tion of the period of the permit must be provided within which this procedure can be completed so that the	 renewal can	 if at all	 be granted well in time before the permit expires. If an application for renewal could be entertained even if made at any stage	 it would dislocate the procedural machinery set out in section 57 and that is why the Legisla ture prescribed in sub section (3) of section 58 that the delay in making an application for renewal may be condoned by the Regional Transport Authority only if it is of not more than 15 days. Here	 the application made by the appel lant for renewal of his permit was admittedly late by more than 15 days and hence the delay was not condonable and the Regional Transport Authority was right in rejecting the application for renewal as time barred. We must	 in the circumstances	 dismiss the appeal	 but in view of the peculiar facts of the case we make no order as to costs. P.B.R. Appeal dismissed.

Under the proviso to section 58(2) of the an application for renewal of an existing permit shall be made not less than 120 days before the date of expiry of the permit. The procedure to be followed in this respect is the same as provided in section 57 for the grant of a fresh permit. Under section 58(3) a delay of not more than 15 days in making the renewal application can be condoned by the Re gional Transport Authority. The proviso to section 68F(1D) provides for the renewal of an existing permit for a limited period when a Scheme is pub lished under section 68C. Since a Scheme was published under this section the appellant made an application under section 68F(1D) for renewal of his permit. R was rejected by the RTA on the ground that there was delay of 18 days which was not capable of being condoned. The Transport Appellate Tribunal dismissed his appeal and the High Court summarily rejected his writ petition. In appeal to this Court it was contended that (i) Chapter IVA of the Act	 which section 68 occurs	 being a self contained code the proviso to section 58(2) was not applicable in the case of an application for renewal filed under the proviso to section 68F(1D) or (ii) in the alternative the delay could be con doned by the RTA for sufficient cause under section 5 read with section 29(2) of the . Dismissing the appeal	 HELD: (1) (a) Section 68F(1D) imposes a prohibition on grant or renewal of permit during the intervening period between the publication of a scheme under section 68C and the publication of the approved scheme and if the proviso were not enacted. renewal of an existing permit expiring after the publication of the scheme under section 68C would have been barred. This	 the legislature did not want and hence the proviso was introduced permitting renewal of an existing permit though for a limited period	 despite the general prohibition enacted in sub section This renewal was not intended to be some special kind of renewal. There is no reason why the provisions of section 57 and the proviso to section 58(2) should not apply in case of a renewal application under the proviso to section 68F(1D).[569 A B] (b) chapter IVA is not a self contained code and the other sections apply to an application under the proviso to section 68F(1D)of the Act. [569D] (i) The procedure in section 57 applies because. there is no other procedure prescribed by the Act. [569C] (ii) The time limit specified in the proviso to section 58(2) also applied as otherwise there would be no time limit for making an application for renewal.[569D] (iii) Section 68F(3) also proceeds on the assumption that	 but for its enactment	 an order made by the RTA under sub~3 (1) or (2) of section 68F would have been appealable under section 64 and it was to exclude the applicability of section 64 that 68F(3) was enacted. [569 E F] 564 (2) The word used in sub section 3 is 'may ' and not 'shall ' and the RTA is given a discretion to entertain an applica tion for renewal of a permit even where it is beyond time	 though not more than 15 days. It could never have been the intention of the legislature that even where there is no sufficient cause for delay in making an application for renewal	 the Regional Transport Authority should still be bound to entertain the application for renewal merely on the ground that the delay is of not more than 15 days. [570F. 571A B] 3 (a) Section 29(2) of the makes section 5 applicable in the ease of an application for renewal unless its applicability can be said to be expressly exclud ed by any provision of the Act. Sub section (3) of section 58 in so many terms says that the RTA .may condone the delay in making of an application for renewal and entertain it on merits provided the delay is of not more than 15 days. This clearly means that if the application for renewal is beyond time by more than 15 days	 the RTA shall not be entitled to entetain it. [571E G] (b) There is an express provision in sub section (3) that delay in making an application for renewal shall be condona ble only if it is of not more than 15 days and that express ly excludes the applicability of section 5 in cases where an application for renewal is delayed by more than 15 days.
