Summarize the following court judgment. minal Appeals Nos. 109 111 of 1963. Appeals from the judgment and order dated May 31	 1963	 of the Bombay High Court in Criminal Applications Nos. 217	 218 and 114 of 1963. The appellants (in Cr. A. Nos. 109 & 110 of 1963) appeared in person. Janardan Sharma and Appellant also	 for the Appellant (in Cr. A. No. 111 of 1963). N. section Bindra and R. H. Dhebar	 for respondents (in Cr. A. Nos. 109 111 of 1963). Purushottam Trikamdas and R. H. Dhebar	 for the respondents (in Cr. A. No. 110 of 1963). 449 January 29	 1964. The Judgment of the Court was delivered by WANCHOO J. These three appeals on certificates granted by the Bombay High Court raise common questions of law and will be dealt with together. They arise out of three habeas corpus petitions filed by the appellants in the High Court under section 491 of the Code of Criminal Procedure challenging their detention under r. 30 of the Defence of India Rules (hereinafter referred to as the Rules). A large number of constitutional questions were raised in the applications and were decided by the High Court against the appellants. These appeals came up for hearing in August 1963 along with some other appeals from decisions of other High Courts	 and the constitutional questions were decided by this Court on September 2	 1963	 (see Makhan Singh Tarsikka vs State of Punjab) (1). It was held therein that the applications under section 491 (1) of the Code of Criminal Procedure were incompetent in so far as they sought to challenge the validity of the detention on the ground that the Defence of India Act and Rules framed thereunder suffer from the vice that they contravened the fundamental rights guaranteed by articles 14	 21	 22(4)	 (5) and (7). The other points raised in the appeals were not considered at that time and it was directed that the appeals should be set down for hearing before a Constitution Bench to be dealt with in accordance with law. Consequently	 these appeals have been put up before this Bench for disposal of the other points raised therein. A preliminary objection has however	 been raised on behalf of the State to the hearing of these appeals on the ground that the orders under which the appellants were detained and which are under consideration in these appeals had been revoked by the State Government and fresh orders of detention had been passed	 and in consequence these appeals had become infructuous. Reliance in this connection is placed on the decision of the Federal Court in Keshav Talpade vs King Emperor(2). In that case the detenu was released while his appeal was pending before the Federal Court. It was however urged on his behalf that even (1) A.T.R. (2) 134 859 S.C. 29. 450 though he had been released and no order could thereafter be made on the habeas corpus application	 the court should pronounce an opinion on the correctness of the High Court 'a ' judgment. The Federal Court refused to do so and dis missed the appeal on the ground that no order in the appeal could be made after the release of the detenu. Generally speaking	 no useful purpose would be served by the appeal court deciding the appeal in a habeas corpus matter where the detenu has been released before the appeal comes up for final hearing. But the facts in the present case are different. Here what has happened is that the earlier order of detention which is the basis of the present appeals has been revoked by the Government of Maharashtra on the ground of a technical defect and a fresh order of detention was passed on the same date	 and the appellants were immediately rearrested after their release from jail under the fresh order of detention. In the Federal Court case	 however	 it appears that the detenu was released and there was no question of a fresh order of detention being made on the same day leading to his re arrert. In the circumstances	 it is urged by the appellants that though technically the appellants were released before the present appeals came up for final hearing	 in substance they are under detention even now and the points of law raised by them. against the earlier order of detention will apply equally to the fresh order of detention. It is therefore urged that the Court should decide the present appeals as that would settle the law and help the detenus in case they make fresh application under section 491 of the Code of Criminal Procedure against the fresh order of detention. It is further urged that the appellants intend after the emergency is over to sue for damages for false imprisonment and the order of the Bombay High Court would stand in their way 'in case such a suit is brought	 and therefore an authoritative pronouncement on the questions of law raised should be made by this Court in the present appeals	 even though technically the order out of which the present appeals have arise ' in has been revoked. We are of opinion that the circumstances of the present cases are different from the circumstances in Keshav Talpade 'scase(1) and therefore it would be in the interests of justice to decide (1) 451 the points raised in the present appeals. We may add that there is nothing to preclude this Court from deciding the appeals even though the order from which these appeals have arisen has been revoked	 though ordinarily this Court would not do so. But as we have already indicated	 it seems to us just and fair 'in view of the fact that the appellants have not been filially released and are still under detention under a fresh order of detention under the Rules that the points raised in these appeals should be decided. The points are of general importance and are likely to arise in many cases. We therefore over rule the	 preliminary objection. The facts in the three appeals are similar and we shall therefore briefly refer to the facts in Appeal No. 1 1 0 for the purposes of dealing with the points raised on behalf of the appellants. The appellants were first detained on November 7	 1962 by an order made by the Commissioner of Police	 Greater Bombay	 under the 	 No. IV of 1950. The matter was then reported to the Government. Before this	 however	 the security of India had been threatened by the Chinese invasion and an Emergency had been declared under article 352 of the Constitution. Further on October 26	 1962	 the Defence of India Ordinance 1962 was passed	 followed by the Rules framed thereunder. When the matter came before the Government	 it decided that the order of November 7	 1962 made by the Commissioner of Police should be revoked and ordered accordingly on November 10. On the same day	 the Government decided to detain the appellants and passed an order under r. 30 of the Rules. This order said that with a view to preventing the appellants from acting in a manner prejudicial to the defence of India	 the public safety and the maintenance of public order	 it was necessary to detain them	. and therefore in exercise of the powers conferred upon the Government by r. 30 of the Rules	 the Government directed the detention of the appellants. This order was served on the appellants in jail. It was challenged by the appellants by filing habeas corpus petition under article 226 of the Constitution and under section 491 of the Code of Criminal Procedure. The 452 High Court	 as already indicated	 dismissed the applications but granted leave to the appellants to appeal to this Court. The constitutional points raised	 as already indicated	 were decided by this Court on September 2	 1963	 and now we are concerned with the other points raised on behalf of the appellants. The first contention that has been urged is that the de tention is illegal inasmuch as the detention order was served on the appellants while they were in jail	 and reliance in this connection is placed on the judgments of this Court in the cases of Rameshwar Shaw vs District Magistrate	 Burdwan(1)	 and Makhan Singh Tarsikka vs The State of Punjab(2). In those cases	 it was held by this Court that where a person is detained in jail as an under trial prisoner no order of detention either under the preventive Detention Act or under the Rules could be served on him because one of the necessary ingredients which go to make up the satisfaction of the detaining authority is necessarily absent in such a case. It was pointed out in Rameshwar Shaw 's case(1) that "before an authority can legitimately come to the conclusion that the detention of the person is necessary to prevent him from acting in a prejudicial manner	 the authority has to be satisfied that if the person is not detained	 he would act in a prejudicial manner and that inevitably postulates freedom of action to the said person at the relevant time. If a person is already in jail custody	 how can it rationally be postulated that if he is not detained	 he would act in a prejudicial manner? At the point of time when an order of detention is going to be served on a person	 it must be patent that the said person would act prejudicially if he is not detained and that is a consideration which would be absent when the authority is dealing with a person already in detention." The same principle was reiterated in the case of Makhan Singh Tarsikka(2). There is however a vital difference between the facts of those two cases and the facts in the present appeals. Those two cases were concerned with the service of an order of detention under the or under the Rules on a person who was in jail in one of two (1) A. I. 1964 S.C. 334. (2) A. I. R. 453 circumstances	 namely (1) where he was in jail as an under trial prisoner and the period for which he was in jail was indeterminate	 or (2) where he was in jail as a convicted person and the period of his sentence had still to run for some length of time. In those cases the service of the order of detention under the or under the Rules in jail would not be legal for one of the necessary ingredients about which the authority had to be satisfied would be absent	 namely	 that it was necessary to detain the person concerned which could only be postulated of a person who was not already in prison. In the present cases	 however	 the appellants were not under detention either as under trial prisoners for an indeterminate time or as convicted persons whose sentences were still to run for some length of time. They were detained under the Pre ventive Detention Act by an order of November 7	 1962 which had been reported to Government for approval and which order could only remain in force for 12 days under section 3 (3) of the unless in the meantime it had been approved by the State Government. The State Government	 however	 decided on November 10	 1962	 to revoke the order of the Commissioner of Police under the and to pass an order itself under the Rules. In those circumstances	 the principle of the two cases referred to above would not in our opinion apply	 for the detention of the appellants depended upon the approval of the State Government. The State Government	 however	 decided to revoke the order of November 7	 1962 and instead decided to pass an order under the Rules on the same day	 namely November 10	 1962. In these circumstances it would be in our opinion an empty formality to allow the appellants to go out of jail on the revocation of the order of November 7	 and to serve them with the order dated November 10	 1962 as soon as they were out of jail. Where the detention is not of the two kinds considered in the cases of Rameshwar shaw(1) and Makhan Singh Tarsikka (2 ) and is either under the or under the Rules	 and its duration is dependent upon the will of the State Government	 we cannot see any reason for holding that if the State Government decides 1964 S.C. 334. (2) A. I. R. 1964 S.C. I 120. 454 to revoke an earlier order of detention it cannot pass a fresh order of detention the same day and serve it on the detenu in jail	 for the two orders are really of the same nature and are directed towards the same purpose. Further the order of the Commissioner dated November 7	 1962 was subject to the approval of the State Government without which it could only be in force for 12 days. In these circumstances the order passed by the State Government on November 10 under the Rules when it had decided to revoke the order of November 7	 1962	 would in our opinion be perfectly valid so far as the time of the making of the order was concerned and its service in jail on the persons who were detained not as under trials or as convicted persons but as detenus	 could not be assailed on the ground on which the order of detention was assailed in the cases of Rameshwar Shaw(1) and Makhan Singh Tariskka(2). The principal of those two cases cannot in our opinion be applied to a case where a fresh order of detention is passed after the cancellation or revocation of an earlier order of detention. The contention therefore that the making of the order of detention on November 10	 1962 or its service in jail in these cases	 makes the detention illegal	 must be negatived. It is next urged that the detaining authority has failed to arrive at that kind of satisfaction which the Rules require. This contention is based on the words of the order dated November 10	 1962. Rule 30 inter alia lays down that the State Government	 if it is satisfied with respect to any particular person that with a view to preventing him from acting in any manner prejudicial to the defence of India and civil defence	 the public safety	 the maintenance of public order	 India 's relations with foreign powers	 the maintenance of peaceful conditions in any part of India	 the efficient conduct of military operations or the maintenance of supplies and services essential to the life of the community	 it is necessary so to do	 may make an order directing that the person be detained. Now the order of November 10	 1962 is in these terms: "No. S.B.III/DOR.1162 IV Home Department (Special) (1) ; (2) A.I.R. 1964 S.C.1120. 455 ORDER "Whereas the Government of Maharashtra is satisfied with respect to the person known as Shri Shamrao Vishnu Parulekar of Bombay that with a view to preventing him from acting in a manner prejudicial to the defence of India	 the public safety and the maintenance of pub lic order	 it is necessary to make the following order: "Now	 therefore	 in exercise of the powers conferred upon it by rule 30 of the Defence of India Rules	 1962	 the Government of Maharashtra does hereby direct that the said Shri Shamrao Vishnu Parulekar be detained. By order and in the name of the Governor of Maharashtra Sd. Deputy Secretary to Government of Maharashtra	 (Home Department) Sachivalaya	 Bombay	 this 10th day of November	 1962". The contention of the appellants is that the first part of the order does not say that it is necessary to detain the appellants. The words used in the first part of the order are "it is necessary to make the following order" and then follows the second part which says that the Government directs that the said person be detained. We are of opinion that when the first part says "it is necessary to make the following order"	 it in effect says that "it is necessary so to do which is what r. 30 of the Rules requires. Reading the order as a whole	 in substance it does say that it is necessary to detain the person with a view to preventing him from acting in a manner prejudicial to the defence of India	 etc. In r. 30 the words are "so to do" while in the order they are "to make the following order". The two expressions in our opinion mean the same thing and we cannot 456 accept the argument that the satisfaction necessary under r. 30 of the Rules was not arrived at in these cases by the authority making the order. Then it is urged that as the State Government is equivalant to the Governor	 it is the Governor who should. be satisfied and not the Home Minister as is the case according to the affidavit filed on behalf of the State Government. The State Government in this connection relies on the Rules of Business	 copy of which has been made available to us. These rules have been framed by the Governor under article 166 of the Constitution for the more convenient transaction of the business of Government and for the allocation among Ministers of the said business. In the affidavit on behalf of the State Government reliance is placed on item 2 (b) of the First Schedule to the Rules of Business dealing with subjects allocated to the Home Department (Special)	 entry (7) which provides for preventive detention for reasons connected with the security of a State	 the maintenance of public order or the maintenance of supplies and services essential to the community. During the hearing	 our attention was drawn to item (1) of the First Schedule to the Rules of Business dealing with subjects allotted to General Administration Department	 entry (44)	 which provides for preventive detention for reasons connected with defence	 foreign affairs or the security of India. It is obvious from the Rules of Business that preventive detention has been divided into two parts and allocated to two different departments. Where preventive detention is for reasons connected with the security of a State	 the maintenance of public order or the maintenance of supplies and services essential to the community	 it can be dealt with by the Minister in charge of item 2 (b) dealing with subjects allocated to the Home Department (Special); but where the preventive detention is for reasons connected with defence	 foreign affairs or the security of India	 it can be dealt with by the Minister in charge of item 1 relating to subjects allotted to the General Administration Department. The detention order in the present cases states that it was made with a view to preventing the appellants from acting in a manner prejudicial to the defence of India	 the public 457 safety and the maintenance of public order. As the deten tion order mentions both the defence of India and the maintenance of public order	 such an order could only be made by a Minister who was in charge both of item 1 relating to subjects allotted to the General Administration Depart ment and of item 2(b) relating to subjects allotted to Home Department (Special). In the affidavit on behalf of the State the order was sought to be justified on the round that it was made by the Home Minister in charge of item 2 (b) relating to subjects allocated to the Home Department (Special). We are of opinion that as the detention order was for reasons connected with the defence of India also	 it could not be dealt with under item 2 (b)	 entry (7) only which item deals with subjects allocated to the Home De partment (Special) and had to be dealt by a Minister who was in charge of both item 1 relating to subjects allotted to the General Administration Department and item 2 (b) relating to subjects allotted to Home Department (Special). In the original affidavit filed on behalf of the State it was however not clear whether the Minister who dealt with these orders was also in charge of the subjects allotted to the General Administration Department but it was stated at the bar that the Minister who dealt with the matter and passed the order on the basis of which the appellants were detained was in charge not only of item 2 (b) relating to subjects allocated to the Home Department (Special.) but was also in charge of item 1 relating to subjects allotted to the General Administration Department. We therefore called upon the State Government to file an affidavit to that effect and an affidavit was filed on December 21	 1963. That affidavit says that the order of November 10	 1962 was passed by the Chief Minister who was at the relevant time in charge both of the General Administration Department as well as the Home Department (Special). We have already referred to the terms of the order of detention. That order refers to three reasons as the basis for the order	 namely	 (i) the defence of India	 (ii) the public safety	 and (iii) the maintenance of public order. Now preventive detention connected with the defence of India could only be ordered under the Rules of Business by the Minister who was in charge of the General Administration Department. 458 while preventive detention for reasons connected with the maintenance of public order could only be ordered by the Minister in charge of subjects allocated to the Home Depart ment (Special). The order therefore in the present case could only be made by a Minister who was in charge both of subjects allotted to the General Administration Department and subjects allotted to the Home Department (Special). In view of the affidavit now filed it appears that the Chief Minister was in charge of both the departments and in the circumstances he could pass the order under challenge. The contention under this head must therefore fail. The next argument is that there is no order of allocation made by the Governor under article 166 of the Constitution after the passing of the Defence of India Ordinance and the Rules framed thereunder and therefore the allocation of business by the	 Rules of Business which were enforced by an order of the Governor dated May 1	 1960 would not be of any effect in allocating the subject of preventive detention arising under the Defence of India Ordinance Act and the Rules to the Minister and the Governor should have passed the order of detention himself. We are of opinion that there is no force in this contention. Allocation of busi ness under article 166 (2) of the Constitution is not made with reference to particular laws which may be in force at the time the allocation is made; it is made with reference to the three lists of the Seventh Schedule to the Constitution	 for the executive power of the Centre and the State together extends to matters with respect to which Parliament and the Legislature of a State may make laws. Therefore. when allocation of business is made it is made with reference to the three Lists in the Seventh Schedule and thus the allocation in the Rules of Business provides for all con tingencies which may arise for the exercise of the executive power. Such allocation may be made even in advance of legislation made by Parliament to be available when ever Parliament makes legislation conferring power on a State Government with respect to matters in List I of the Seventh Schedule. It was therefore in our opinion not necessary that there should have been an allocation made by the Governor under article 166 (3) of the power to detain under 459 the Defence of India Ordinance	 Act and Rules after they were passed; it will be enough if the allocation of the sub ject to which the Defence of India Ordinance	 Act and Rules refer has been made with reference to the three Lists in the Seventh Schedule and if such allocation already exists	 it may be taken advantage of if and when laws are passed. Preventive detention is provided for in List 1	 item 9	 for reasons connected with defence	 foreign affairs and the security of India	 and in item 3 of List III for reasons connected with the security of a State	 the maintenance of public order	 or the maintenance of supplies and services essential to the community. The allocation of business made under article 166 is in pursuance of these entries in the three Lists in the Seventh Schedule and would be available to be used whenever any law relating to these entries is made and power is conferred on the State Government to act under that law. The contention of the appellants that fresh allocation should have been made under article 166 (3) by the Governor after the passing of the Defence of India Ordinance	 Act and Rules must therefore fail. Lastly reliance is placed on sections 40 and 44 of the Defence of India Act. Section 40 gives power to the Central Government to delegate its powers under the Act or the Rules to any officer or authority subordinate to the Central Government or to any State Government or any officer or authority subordinate to such Government or to any other authority	 and the argument is that before the State Government can exercise the power conferred by r. 30	 there has to be a delegation by the Central Government. This argument in our opinion is misconceived. It is true that section 40 gives authority to the Central Government to delegate its powers under the Act or the Rules to the State Government and others. But no delegation under that section is required for the exercise of the power under r. 30 by the State Government	 for r. 30 itself lays down that the power there in can be exercised by the Central Government or the State Government. No further delegation therefore was necessary in favour of the State Government in so far as the exercise of power under r. 30 is concerned. 460 Next it is urged that the order of detention does not show that section 44 was kept in mind when it was made. Section 44 lays down that "any authority or person acting in pursuance of this Act shall interfere with the ordinary avocations of life and the enjoyment of property as little as may be consonant with the purpose of ensuring the public safety and interest and the defence of India and civil defence". It is urged that an order of detention necessarily interferes completely with the ordinary avocation of life of the person detained and therefore before such an order could be made	 section 44 should be borne in mind. Therefore the order of detention is to be made when it is the only way of carrying out the purposes of the Act	 for section 44 provides that there should be as little interference with the ordinary avocations of life as possible under the Act. The argument further is that r. 30 (1) provides as many as eight clauses which provide for the regulation of conduct of an individual and cl. (b) relating to detention	 which amounts to complete interference with the avocation of life of the detenu could only be resorted to in view of section 44 when it is shown that no other way of regulating the conduct of the person de tained as provided in the other clauses of r. 30 (1) would meet the needs of the situation. So it is urged that unless the order shows on the face of it that the State Government thought that the detention was the only mode in which the purposes of the Act and the Rules could be carried out	 the order would be bad in view of section 44 of the Act. We are of opinion that there is no force in this contention. It is true that section 44 provides that there should be as little interference with the ordinary avocations of life as possible when orders are made under the Act or the Rules; but that does not mean that a detention order must show on the face of it that the State Government had considered the various clauses of r. 30 (1) and had come to the conclusion that the only way in which the purposes of the Act and the Rules could be carried out was by the use of cl. (b) of r. 30 (1). In our opinion when the order says that it is necessary to make an order of detention in order to restrain the prejudicial activities mentioned therein it means that that was the only way which the State Government thought was necessary to adopt in order to meet the situation. It will then 461 be for the detenu to show that the order had gone beyond the needs of the situation and was therefore contrary to section 44. No such thing has been shown in the present cases and we are satisfied that the orders in question cannot be said to go beyond the needs of the situation	 even assuming that section 44 is mandatory as urged on behalf of the appellants and not merely directory as urged on behalf of the State. The appeals therefore fail and are hereby dismissed.

Appellants were first detained on November 7	 1962 under . That order was revoked by the Government and the appellants were released but re arrested under Rule 30 of the Defence of India Rules. The orders of detention were served on appellants in Jail. The appellants challenged those orders in the High Court by filing habeas corpus petitions under article 226 of the Constitution and section 491 of the Code of Criminal Procedure. The writ petitions were dismissed by the High Court and the appellants came to this Court under a certificate from the High Court. The contentions raised by the appellants were that their detention was illegal because the detention order was served on them when they were in jail	 that the orders of detention were passed without the satisfaction of the authority concerned regarding their necessity	 the satisfaction was to be that of the Governor and not of any Minister	 that there should have been fresh allocation of business by the Governor under article 166(3) of the Constitution after the passing of the Defence of India Ordinance	 Act and Rules	 that before the State Government could exercise the power conferred by Rule 30	 there had to be delegation by the Central Government that the order of detention did not show that section 44 of Defence of India Act was kept in mind when the order was made and that unless the order showed on the face of it that the State Government thought that detention was the only mode in which the purpose of the Act and Rules could be carried out	 the order was bad. Dismissing the appeals. Held: The orders of detention passed by the State Government and their service on the appellants in jail were perfectly valid and did not make the detention illegal. The appellants were detained not as undertrials or as convicted persons but as detenus and hence the cases of Rameshwar Shaw and Makhan Singh Tarsikka did not apply in the present case. Reading the detention order as a whole	 it was clear that it did Ray in substance that it was necessary to detain the appellants with a view to preventing them from acting in a manner prejudicial to the Defence of India	 public safety and maintenance of public order. There was no difference between the words "so to do" in Rule 30 and the words "to make the following order ' in the detention order. As the detention order mentioned both the defence of India and maintenance of public order	 such an order could be made on the satisfaction of a Minister who was incharge of both the subjects in view of the Rules of Business promulgated by the Governor. It was not necessary that fresh allocation of business should be made by the Governor under article 166(3) after the passing of the Defence of India Ordinance	 Act and Rules. It Is enough if the allocation of the 448 subject to which the Defence of India Ordinance	 Act and Rules refer has been made with reference to the three lists in the Seventh Schedule and if such allocation already exists	 it may be taken advantage of if and when laws are passed. Rule 30 of the Defence of India Rules lays down that the power can be exercised by the Central Government or the State Government and hence no further delegation is necessary in favour of the State Government for the exercise of power under Rule 30. It is true that section 44 of the Defence of India Act provides that there should be as little interference with the ordinary avocation of life as possible when orders are made under the Act or the Rules	 but that does not mean that a detention order must show on the face of it that the State Government had considered the various clauses of Rule 30(1) and had come to the conclusion that the only way in which the purpose of the Act and the Rules could be carried out was by the use of Rule 30(1) (b). When the order says that it is necessary to make an order of detention in order to restrain the prejudicial activities mentioned therein	 it means that that was the only way which the State Government thought was necessary to adopt in order to meet the situation. It is for the detenu to show that the order had gone beyond the needs of the situation and was therefore contrary to section 44.
