Summarize the following court judgment. vil Appeal Nos. 3490 91 of 1987. From the Judgment and Order dated 5.3. 1986 and 1.4.1986 of the Andhra Pradesh Administrative Tribunal	 Hyderabad in R.P. Nos. 1595 of 1983 and 788 of 1984. P.A. Choudhary	 T.V.S.N. Chari	 Ch. Badrinath and Mrs. Sumitha Rao for the Appellants. C. Seetharammayya	 B. Parthasarthi and A. Subba Rao for the Respondents. The Judgment of the Court was delivered by NATARAJAN	 J. These appeals by the State of Andhra Pradesh are directed against the judgments of the Andhra Pradesh Administrative Tribunal	 Hyderabad	 in R.P. Nos. 1595 and 788 of 1984. Originally	 the Government of Andhra Pradesh	 in purported exercise of its powers under Clause 5 of Article 371 D of the Constitution passed an order G.O. Ms. No. 215 dated 14.7.1986 to annul the two judgments of the Tribunal. On 20.12.1986	 this Court negatived the powers of annulment assumed by the State Government by striking down Clause 5 of Article 371 D and the proviso thereto as being opposed to the basic structure of the Constitution. Thereafter	 the State has.preferred these appeals by special leave against the judgments of the Administrative Tribunal. What falls for consideration in these appeals is whether amended Rule 3 of the Andhra Pradesh Treasury and Accounts Subordinate Service Rules 1963 (hereinafter referred to as the Rules) is violative of the Andhra Pradesh Public Employ ment (Organisation of Local Cadres and Regulation of Direct Recruitment) Order	 1975 (hereinafter referred to as the Presidential Order) issued on 18.10.1975 by the President of India under clauses 1 and 2 of Article 371 D of the Consti tution. The validity of the amended Rule was questioned in the context of certain Assistant Section Officers in the Finance Department of the Government of Andhra Pradesh (hereinafter referred to as the 346 Secretariat Officers) borne on zone VII being appointed to the post of Sub Treasury Officers borne on the Subordinate Offices under the Directorate of Treasuries and Accounts (hereinafter referred to as the Local Cadre) borne on zones I to IV. For a proper appreciation of the matter	 it is necessary that Rule 3 before and after amendment and the Presidential Order are set out. Under Rule 3 of the Rules	 the posts of Head Accountants and Sub Treasury Officers could be filled up by any of the following methods: (i) By direct recruitment; (ii) By promotion from category 3	 4 or 5 of Branch II or from category 3 of Branch I	 III	 IV	 VI or category 2 of Branch VIi; and (iii) By transfer from among the U.D. Clerks (now called Assistant Section Officers) in the Finance Department of the Secretariat. Rule 3 thus made provision for the posts of Head Accountants and Sub Treasury Officers being filled inter alia by: Promotion of Upper Division Clerks of the Directorate of Treasuries and Accounts & Transfer from among the Assistant Section Officers in the Finance Department of the Secretari at. However as per other Rules	 only 4 Assistant Section Offi cers	 at any given time were eligible for being recruited as Sub Treasury Officers. On 18.10.1975	 the Presidential Order came to be passed. Para 3 of the Order which enjoins the State Government to organise the posts under the State into different local cadres reads as follows: "3. Organisation of Local Cadres (1) The State Government shall	 within a period of twelve months from the commence ment of this Order	 organise classes of posts in the civil services of	 and classes of civil posts under the State into different local cadres for different parts of the state to the extent	 and in the manner	 hereinafter provided." 347 Para 5 which deals with local cadres and transfers of per sons consists of 2 sub paras. The para reads as follows: "5. Local Cadres and transfers of persons (1) Each part of the State for which a local cadre has been organised in respect of any category of posts	 shall be a separate unit for purposes of recruitment	 appointment	 discharge	 seniority	 promotion and transfer	 and such other matters as may be specified by the State Government	 in respect of that category of post. (2) Nothing in this Order shall prevent the State Government from making provision for (a) the transfer of a person from any local cadre to any Office or Establishment to which this Order does not apply	 or vice versa; (b) the transfer of a person from a local cadre comprising posts in any Office or Establishment exercising territorial jurisdiction over a part of the State to any other local cadre comprising posts in such part	 or vice versa; and (c) the transfer of a person from one local cadre to another local cadre where no qualified or suitable person is avail able in the latter cadre or where such transfer is otherwise considered necessary on the public interest. A fourth clause was subsequently inserted as per G.O. Ms. No. 34 G.A.D. (S.P.F.) dated 24.1.81 and it reads as follows: (d) the transfer of a person from one local cadre to another local as reciprocal condition subject to the condition that the persons so transferred shall be assigned seniority in the latter cadre with reference to the date of his transfer to that cadre. " Thereafter	 the Government of Andhra Pradesh by G.O.P. No. 728 General Administration S.P.W.A. Department dated 1.11.1975 issued various instructions in relation to the aforesaid Presidential Order including para 5 regarding inter cadre transfers. 348 Seven persons belonging to category 5 of Branch II of the A.P. Treasury and Accounts Subordinate Service presented a representation petition No. 706 of 78 before the A.P. Administrative Tribunal for declaring Rule 3 of the Rules ultra vires	 in so far as it made provision for promotion of Clerks of the Directorate of Treasuries and Accounts and Assistants of the Finance Department of the Secretariat to the posts of Head Accountants and Sub Treasury Officers	 in violation of para 5(1) of the Presidential Order. It was urged by them that with the promulgation of the Presidential Order	 the posts of Head Accountants and Sub Treasury Offi cers had become zonal posts and as such the zone will be the unit for recruitment	 appointment	 discharge	 seniority	 promotion and transfer to such a zonal post under paragraph 5(1) of the Presidential Order. They claimed that the Serv ice rules issued under Article 309 of the Constitution	 as they existed at the time of the Presidential Order did not conform to the local cadres created under the Presidential Order and hence the State Government had issued G.O. No. 728 for suitable amendments being made to the Service Rules in each service. They further claimed that only the U .D. Accountants of the Feeder Sources of the zone alone are eligible for consideration in that particular zone for promotion to the rank of Head Accountant and Sub Treasury Officer and not the personnel from other zones including U.D. Accountants of the Directorate of Treasuries and Ac counts and Assistants of the Finance Department of the Secretariat. In reply the State of A.P. while admitting that under the Presidential Order	 the posts of Head Accountant/Sub Treasury Officers were organised into zonal posts nevertheless contended that the personnel from differ ent categories mentioned under the Rules are entitled for being considered for promotion to the rank of Head Account ants/Sub Treasuries Officers by reason of para 5(2)(a) of the Presidential Order and the detailed instructions con tained in para 10(a) of G.O.P. No. 728 dated 1.11.1975. The relevant portion in G.O.P. No. 728 dated 1.11.1975 reads as follows: "Though posts may be organised into separate local cadres	 para 5(2) of the Presidential Order provides that the State Government may make a provision for transfer of persons from	 and to	 local cadres under certain circumstances. These are elucidated below: (a) Transfer of a person from any local cadre to any office or establishment to which the order does not apply	 or vice versa. 349 This enables a provision being made for drawing persons on tenure basis from different local cadres to fill equivalent posts in Major Development Projects	 Special Offices or Establishments etc. There are also cases where provision exists for appointment of persons in mofussil offices by transfer to the offices of Heads of Departments. For in stance	 a certain proportion of ministerial posts in the offices of Heads of Departments is to be filled by transfer from ministerial categories in the subordinate offices in the districts. A provision of this kind is protected under the Presidential Order. " The full bench of the Tribunal considered the rival conten tions of the parties and came to the view that para 5(1) of the Presidential Order made it clear that for the purpose of promotion	 zonal cadre has to be treated as a separate unit and consequently the posts of Head Accountants/Sub Treasury Officers	 which have been declared as zonal posts could be filled up by promotion only on zonal basis and consequently Rule 3 of the Rules which specified various categories of posts without reference to zone as feeder posts for the purpose of promotion to the posts in question are inconsist ent with para 5(1) of the Presidential Order. The Full Bench therefore held that "after the promulgation of Presidential Order the provisions of Rule 3 referred to above would have to be reviewed so as to make them consistent with the provi sions of the Presidential Order. " The Full Bench also con sidered the scope and effect of G.O. No. 728 dated 1.11.75 and held as follows: "In our opinion	 once this point is conceded	 the contents of paragraph 10 of G.O. (P) No. 728 dated 1.11.1975 cited by the respondents in this respect would be properly understood. What that paragraph clearly suggests is that under paragraph 5(2) of the Presidential Order it is open to the State Government to authorise transfer of a person from any local cadre to any office or establishment to which the order does not apply or vice versa. It is in this context that the particular paragraph clarifies the types of trans fers which the Government would authorise. The sentence "a provision of this kind is protected under the Presidential Order" occurring in that paragraph has	 therefore	 to be read as conveying that a provision of this kind could be made by the State Government under paragraph 5(2) of the Presidential Order. Apparently the respondents have mis 350 interpreted this sentence to understand that the provision of Rule 3 of A.P. Treasuries and Accounts Subordinate Serv ice Rules in question continues to be operative without any specified provision being made in the rules in pursuance of the authority given to the State Government under paragraph 5(2) of the Presidential Order. This clearly cannot be the correct interpretation as discussed above." (Emphasis supplied) Thus it came about that the Full Bench declared that the various categories of feeder posts including Assistants	 (now named Assistant Section Officers of the Secretariat) from which promotion to the posts of Head Accountants/Sub Treasury Officers can be made	 cannot be made operative after the promulgation of the Presidential Order. After the Full Bench of the Tribunal rendered its judg ment holding that Rule 3 ceased to have operative force after the Presidential Order was made	 the State Government amended Rule 3 and gave retrospective effect to the amended Rule with effect from 18.10.1975. The amendment to the Rule was made in the following terms: "The amendment hereby made shall be deemed to have come into force on the 18th October	 1975. AMENDMENT In the said rules	 in the Table under Rule 3	 in column (3) against category (2) Head Accountants and Sub Treasury Officers of Branch II for items (ii) and (iii)	 the follow ing items shall be substituted	 namely: (ii) By promotion from category 3	 4 or 5 of Branch II; (iii) By transfer from among the category of Upper Division Accountants (Senior Accountants) of Branch I	 Branch III or Branch VI or Upper Division Accountants (Senior Accountants) of Branch VII); (iv) By transfer from among the category of Assistants (Assistant Section Officers) of Finance and Planning (Fi nance Wing) Department of the Secretariat. " Challenging the validity of the amended rule two representa tion 351 petitions viz. R.P. No. 1595 of 83 and R.P. No. 788 of 84 came to be filed before the A.P. Administrative Tribunal. Once again	 a plea was raised that amended Rule 3 was also violative of the Presidential Order. The State contended that the amended Rule had been issued by the Governor in exercise of the powers conferred on him by the proviso to Article 309 of the Constitution and hence the validity of the Rule cannot be questioned by the petitioners. It was secondly contended that the earlier G.O. was not violative of the Presidential Order or the provisions of Article 371 D	 but even so as it was considered by the Tribunal to be inoperative because the special provisions did not explicity state that they had been made in exercise of the authority vested in the State Government under para 5(2) of the Presi dential Order	 the Government had set right the lacuna pointed out by the Tribunal by framing the amended rule specifically in exercise of the powers conferred on Govern ment under para 5(2) of the Presidential Order. The Tribunal held that what was challenged by the peti tioners was not the powers of the Governor to issue the statutory rule but the Government 's power to fill a zonal post by the method of transfer by a person who did not belong to the zone in which the vacancy had arisen by refer ring to para 5(2) of the Presidential Order in the Preamble of the Notification making the amendment. Dealing with this question the Tribunal referred extensively to the judgment rendered by the Full Bench of the Tribunal in the earlier case R.P. No. 708 of 78 and held that the judgment of the Full Bench did not afford scope to the State Government to pass a G.O. in conflict with para 5(1) of the Presidential Order and furthermore the impugned G.O. Ms. No. 196 did not set out under which sub para viz. sub para a	 b or c in para 5(2) of the Presidential Order the G.O. was issued and therefore the amended G.O. cannot be upheld. It was also held by the Tribunal that there was no justification for transferring a person who does not belong to concerned zone to be inducted into that zone merely because such a practice had existed in the past and moreover the underlying purpose of the Presidential Order would be destroyed if the State Government is allowed to fill up vacancies in zonal posts by a person not belonging to that zone. It is the correctness of the view taken by the Tribunal that is challenged in these appeals. Mr. T.V.S.N. Chari	 learned counsel for the State and Mr. Seetaramiah	 learned counsel for the respondents ad vanced arguments in support of their respective contentions in the appeals. 352 Before we examine the correctness of the view taken by the Tribunal striking down the amended Rule 3 as being violative of the Presidential Order	 we may usefully recall the relevant provisions of the Presidential Order which have to be borne in mind. As already stated para 3(1) enjoins the State Government to organise various classes of posts in the civil services and classes of civil posts under the State into different local cadres for different parts of the State in accordance with the further provisions contained in para 3. For our purposes it is unnecessary to refer to the other provisions of para 3 except to point out that the direction contained in para 3(1) is not an inexhorable one. Sub para 8 of para 3 makes provision for the Central Government	 if it is not practicable or expedient to organise local cadres under the paragraph in respect of any non gazetted category of posts in any department	 to make a declaration to that effect	 and it is further provided that on such declaration being made	 the provisions of the para shall not apply to such category of posts. It is	 however	 common ground that the posts of Head Accountants and Sub Treasury Officers have been constituted into Zones I to IV and the U.D. Assistants and Assistant Section Officers in the Finance Department of the Secretariat have been organised for the city of Hydera bad into a separate category falling under Zone VII. The question for consideration is whether the U.D. Clerks of the Directorate and Assistant Section Officers in the Secretari at falling under Zone VII can be transferred by promotion to the local cadre posts in zones I to IV. The Tribunal has held that such transfers cannot be effected for the follow ing reasons: 1. The reasons which weighed with the full Bench for strik ing down the unamended Rule 3 will hold good for striking down of the amended Rule 3 also. The amendment to the Rule cannot be deemed to have been regularly effected by the Government because the Rule does not set out under which relevant clause viz. clause (a)	 (b) or (c) of sub para 2 of para 5 of the Presidential Order the Government has exercised its powers to amend the Rule. The amendment sought to be effected by the Govt. would have the effect of destroying the scheme of constituting separate local cadres and separate zones contained in para 5(1) of the Presidential Order. There is no convincing reason as to why persons in the Directorate who do not belong to Zones I to IV should be in 353 ducted into those zones and the system cannot be allowed to be continued merely because such a practice was in vogue prior to the issue of the Presidential Order. Since the amended Rule is virtually a repetition of the old Rule	 it cannot be legitimised merely because Government claims to have amended the Rule in purported exercise of its powers under para 5(2) of the Presidential Order. On a consideration of the matter	 we find that the Tribunal has clearly erred in everyone of the reasons given by it for striking down the amended Rule 3. In the first place	 we must point out that the Tribunal has failed to construe para 5(2) of the Presidential Order in its proper perspective and give full effect to the powers conferred thereunder on the State Government to make provi sions contrary to the scheme of local cadres prescribed under Para 5(1). The words of sub para (2) of Para 5 viz. "nothing in this order shall prevent the State Government from making provision for" sets out the over riding powers given to the State Government under the sub para. Such over riding powers have been given to the State Government in express terms in recognition of the principle that public interest and administrative exigencies have precedence over the promotional interests of the members belonging to local cadres and zones. Since Para 5(2) also forms a part of the Presidential Order	 it forms part of the scheme envisaged for creating local cadres and zones. The Tribunal was	 therefore	 in error in taking the view that if the State Government was to exercise its powers under Para 5(2) and make provision for promotion of UD Assistants in the Direc torate and Assistant Section Officers in the Secretariat to be transferred to posts in Zones I to IV	 it will be the very negation of the creation of cadres and zones under Para 5(1) and it will be destructive of the scheme underlying the Presidential Order. In fact the Tribunal has realised the operative force of Para 5(2) to some extent but it has failed to give full effect to its realisation of the scope of Section5(2). In Para 12 of its judgment in RP No. 1595 of 1983 the Tribunal has stated that since the amended rule refers to Para 5(2) of the Presidential Order "it will no longer be open to the petitioners to attack the amendment as was done in respect of the earlier amendment in the previous RP". The Tribunal has thus noticed that the amended Rule has been brought about by the Government in exercise of its powers under Para 5(2) but it has failed to draw the logical inference following therefrom. 354 As regards the view taken by the Tribunal that the reasons which weighed with the Full Bench for holding that the unamended Rule ceased to have operative force after the Presidential Order was made would have relevance even with reference to the amended Rule	 the Tribunal cannot be said to have acted correctly. The Full Bench was concerned with the amended Rule 3 which was framed long before the Presi dential Order was passed. In order to make the provisions of the old Rule to have currency even after the Presidential Order was passed	 the Government issued G.O. Ms. No. 728 on 1 11 75. However	 the Full Bench was of the view that the G.O. did not conform to the requirements of para 5(2) of the Presidential Order and therefore the Full Bench held the old Rule cannot have operative force "without any specific provision being made in the Rules in pursuance of the au thority given to the State Government under para 5(2) of the Presidential Order. " It was in acceptance of this position the Government had issued G.O. Ms. No. 196 dated 17.6.83 for amending Rule 3 so as to make the Rule conform to the re quirements of para 5(2) of the Presidential Order. The Tribunal has failed to realise this position and has there fore committed the error of holding that the view taken by the Full Bench with reference to the old Rule will continue to hold good even with reference to the amended Rule. Anoth er patent error which the Tribunal has committed is in holding that G.O. Ms. No. 196 is not valid because it does not set out the relevant clause under which the Government was exercising its powers under the Presidential Order. The Tribunal 's observation is worded as under: "In the impugned G.O. Ms. No. 196 supra	 no particular sub paragraph has been invoked. The situation under which each sub sub para will be applicable has been stated. Clearly provisions contained in sub sub para (b) and (c) are not attracted; much less sub sub para (a). We are	 therefore	 not convinced that recruitment by the method of transfer could come under any one of the aforesaid provisions. " The observations of the Tribunal is manifestly wrong because G.O. Ms. No. 196 clearly sets out that the Notification was being issued by the Government in exercise of its powers under Section 3 of the Andhra Pradesh Ordinance 5 of 83 read with para 5(2)(a) of the Presidential Order. The Tribunal has completely lost sight of the relevant portion of the G.O. We are now only left with the reasoning of the Tribunal that there is no justification for the continuance of the old Rule and for 355 personnel belonging to other zones being transferred on promotion to offices in other zones. In drawing such conclu sions	 the Tribunal has travelled beyond the limits of its jurisdiction. We need only point out that the mode of re cruitment and the category from which the recruitment to a service should be made are all matters which are exclusively within the domain of the Executive. It is not for judicial bodies to sit in judgment over the wisdom of the Executive in choosing the mode of recruitment or the categories from which the recruitment should be made as they are matters of policy decision falling exclusively within the purview of the Executive. As already stated	 the question of filling up of posts by persons belonging to other local categories or zones is a matter of administrative necessity and exigency. When the Rules provide for such transfers being effected and when the transfers are not assailed on the ground of arbi trariness or discrimination	 the policy of transfer adopted by the Government cannot be struck down by Tribunals or Court of law. In the light of our discussion	 we find that the griev ance expressed by the State over the judgment of the Tribu nal is well founded. In so far as Civil Appeal No. 3491 of 87 is concerned	 though there was no direct challenge there in to the validity of the amended Rule 3	 the Tribunal has allowed the Representation Petition filed by the petitioners because of the view taken by it in R.P. No. 1595 of 1983. Hence the judgment of the Tribunal in that case also has to be set aside. In the result	 we set aside the judgments of the Tribu nal	 and allow both the appeals and declare Rule 3 of the amended Rule to be intra vires of the Presidential Order. There will be no order as to costs. Y. Lal Appeals allowed.

In these two appeals filed by the State of Andhra Pra desh against the orders of the Andhra Pradesh Administrative Tribunal	 the question that arises for consideration is whether amended Rule 3 of the Andhra Pradesh Treasury and Accounts Subordinate Service Rules 1963 Is violative of the Andhra Pradesh Public Employment (Organisation of Local Cadres and Regulation of Direct Recruitment) Order 1975. The circumstances under which this question has arisen are stated hereinbelow. Prior to the filing of Representative Petitions Nos. 1595 and 788 of 1984 by the Respondents in the Tribunal out of which these appeals have arisen	 seven persons belonging to category 5 of Branch II of the Andhra Pradesh Treasury and Accounts Subordinate Service had presented a Petition before the Andhra Pradesh Administrative Tribunal challeng ing the vires of Rule 3 of the Andhra Pradesh Treasury and Accounts Subordinate Service Rules 1963	 being violative of para 5(1) of Andhra Pradesh Public Employment Order	 issued by the President of India under clauses (1) & (2) of Article 371 D of the Constitution	 inter alia on the ground that it made provision for promotion of clerks of the Directorate of Treasuries and Accounts and Assistants of the Finance De partment of the Secretariat to the post of Head Accountants and Sub Treasury Officer which posts had become Zonal posts after the promulgation of Presidential order. According to them only the U.D. Accountants of the feeder sources of the Zone were eligible for consi 343 deration in that particular Zone for promotion to the rank of Head Accountant and Sub Treasury Officer and not the personnel from the other Zones	 including U.D. Accountants of the Directorate. The Tribunal held that by virtue of para 5(1) of the Presidential order	 for purposes of promotion	 Zonal Cadre had to be treated as a separate unit and consequently the posts of Head Accountants/SubTreasury Officers	 could be filled up by promotion only on Zonal basis and as such Rule 3 which specified various categories of posts without refer ence to Zone as feeder posts for the purpose of promotion to the posts in question were inconsistent with para 5(1) of the Presidential order. The Tribunal therefore declared that after the promulgation of Presidential order	 the provisions of Rule 3 would have to be reviewed so as to make them consistent with the provisions of the Presidential order. The Tribunal further declared that various categories of feeder posts including the posts of Assistant Section Offi cers of the Secretariat from which promotion to the posts of Head Accountants/Sub Treasury Officer could be made	 Could not be made operative after the promulgation of the Presi dential order. After the aforesaid decision of the Tribunal	 the State Government amended Rule 3 and gave it a retrospec tive operation w.e.f. 18.10.1975. The validity of the amended Rule was questioned by the Respondents in the context of certain Assistant Section Officers in the Finance Department (Secretariat Service) borne on Zone VII being appointed to the post of Sub Treas ury Officers borne on the Subordinate Offices under the Directorate of Treasuries and Accounts borne on Zones I to IV	 by filing the said Representation Petitions before the Andhra Pradesh Administrative Tribunal. It was again con tended before the Tribunal that the amended Rule 3 was violative of the Presidential order. According to the State the amended Rule had been issued by the Governor in exercise of the power conferred on him by the Proviso to Article 309 of the Constitution and hence the validity of the Rule could not be questioned by the Petitioners. It was further con tended by the State that the earlier G.O. was not violative of the Presidential order of the provisions of Article 371 D	 but even so	 as it was considered by the Tribunal to be inoperative because the special provision did not explicitly state that they had been made in exercise of the authority vested in the State Government under para 5(2) of the Presi dential order	 the Government had set right the lacuna by framing the amended Rule specifically in exercise of the powers conferred on Government under para 5(2) of the Presi dential order. 344 The Tribunal held that the impugned G.O. 196 did not set out under which sub para viz.	 sub para (a)	 (b) or (c) in para 5(2) of the Presidential order	 the G.O. was issued and therefore the amended G.O. could not be upheld. The Tribunal also declared that there was no justification for transfer ring a person who did not belong to concerned Zone to be inducted into that Zone	 as that would defeat the underlying purpose of the Presidential order. The State has	 therefore	 preferred these appeals. Allowing the appeals this Court	 HELD: That the Tribunal has failed to construe para 5(2) of the Presidential order in its proper perspective and give full effect to the powers conferred thereunder on the State Government to make provisions contrary to the scheme of local cadres prescribed under para 5(1). The words in para 5(2) viz.	 "nothing in this order shall prevent the State Government from making provision for" sets out the over riding powers given to the State Government under the sub para. Such overriding powers have been given to the State Government in express terms in recognition of the principle that public interest and administrative exigencies have precedence over the promotional interests of the members belonging to local cadres and zones. [353C E] In order to make the provisions of old rule to have currency even after the Presidential order was passed	 the Government issued G.O. Ms. No. 728 on 1.11.75. The Govern ment has issued G.O. Ms. No. 196 dated 17.6.83 for amending Rule 3 so as to make the Rule conform to the requirements of para 5(2) of the Presidential order. [354B	 C D] The mode of recruitment and the category from which the recruitment for a service should be made are all matters which are exclusively within the domain of the Executive. It is not for judicial bodies to sit in judgment over the wisdom of the Executive in choosing the mode of recruitment or the categories from which the recruitment should be made as they are matters of policy decision failing exclusively within the purview of the Executive. [355B] The question of filling up of posts by persons belong ing to other local categories or zones is a matter of admin istrative necessity or exigency. When the rules provide for such transfers being effected and when the transfers are not assailed on the ground of arbitrariness or discrimination the policy of transfer adopted by the Government cannot be struck down by Tribunals or Court of Law. [355C] 345 Rule 3 of the amended Rule declared to be intra vires of the Presidential Order. [355E F]
