Summarize the following court judgment. No. 7 of 1972. Under Article 32 of the Constitution of India for a writ In the	 nature of habeas corpus. H. K. Puri	 for the petitioner. D. N. Mukherjee and G. section Chatterjee	 for the respondent. The Judgment of the Court was delivered by Khanna	 J. This is a petition through _jail for the issuance of ' a writ of habeas corpus by Nishi Kanta Mondal who has been ordered by the District Magistrate	 24 Parganas to be detained under section 3 of the West Bengal (Prevention of Violent Activities) Act	 1970 (President 's Act No. 19 of 1970)	 hereinafter referred to as the Act. The order of detention reads as under "GOVERNMENT OF WEST BENGAL OFFICE OF THE DISTRICT MAGISTRATE 24 PARGANAS ORDER No. 352/71 Dated	 the 6 7 71 Whereas I am satisfied with respect to the person known as Shri Nishi Kanta Mondal	 son of Shri Radhanath Mondal of Daccapara	 P. section Bongaon	 Dt. 24 Parganas that with a view to preventing him from acting in any manner prejudicial to the maintenance of public order	 it is necessary so to do	 I therefore in exercise of the powers conferred by sub section (1) read with sub section (3) of section 3 of the West Bengal (Prevention of Violent Activities) Act	 1970 (President 's Act No. 19 of 1970)	 make this order directing that the said Nishi Kanta Mondal be detained. Given under my hand and seal of office. Sd/ DISTRICT MAGISTRATE 24 PARGANAS 6 7 71" In pursuance of the above order	 the petitioner was arrested on July 8	 1971 and was served with the order as well as the 226 grounds of detention on the same day. On July 10	 1971 the District Magistrate sent report to the State Government about his having passed the order for 'the detention of the petitioner. The grounds of detention and other necessary particulars were also sent along with the report. The State Government	 after considering the report and other particulars	 approved the detention order on July 17	 1971. Representation made by the petitioner against his detention was received by the State Government on July 30	 1971. The representation was considered by the State Government and rejected on August 5	 1971. The case of the petitioner was placed before the Advisory Board on August 6	 1971. The petitioner 's representation was also sent to the Advisory Board. The Advisory Board	 after considering the material placed before it as well as the representation sent by the petitioner and after giving him a hearing in person	 submitted its report to the State Government on September 14	 1971. Opinion was expressed by the Advisory Board that there was sufficient cause for the detention of the petitioner. The State Government passed an order on October 5	 1971 confirming the order for the 	detention of the petitioner. The confirmation order was there	after communicated to the petitioner. The petition has	 been resisted by the State of West Bengal and the affidavit of Shri Chandi Charan Bose	 Deputy Secretary	 Home (Special) Department	 Government of West Bengal has been filed in opposition to the petition. Mr. Puri has addressed arguments amicus curiae on behalf of the petitioner	 while the respondent State has been represented by Mr. D. N. Mukherjee. The first contention which has been advanced by Mr. Puri is that the Act was enacted by the President in exercise of the powers conferred by	 section 3 of the West Bengal State Legislature (Delegation of Powers) Act	 1970. According to section 3 of the last mentioned Act	 the power of the Legislature of the State of West Bengal to make laws	 which 'had been declared by the Proclamation to be exercisable by or under the authority of Parliament	 was conferred on the President. In the exercise of the said power	 the President could	 from time to time whether Parliament was or was not in session	 enact. as a President 's Act	 a Bill containing such provisions as he considered necessary. Some other formalities	 detailed in section 3	 were also required to be complied with by the President	 but it is not necessary for the purpose of this case to 'refer to	 the. Section 2 of the aforesaid Act defined "Proclamation" to mean the Proclamation issued on the 19th day of March	 1970	 under article 356 of the Constitution by the President	 and published with the notification of the Government of India it) the Ministry of Home Affairs No. G.S.R. 490 of the said date	 It is urged 227 by Mr. Puri that the above mentioned Proclamation was revoked by the President by another Proclamation in the beginning of this month. On account of the revocation of the Proclamation	 the President 's Act No. 19 of 1970	 according to the learned counsel	 ceased to have effect. As such	 the petitioner could not be kept in detention in pursuance of the order made under that Act. There is	 in our opinion	 no force in the above contention because it is based upon the assumption that the law made by the President ceases to operate immediately upon the revocation of the Proclamation. This assumption is not correct and runs contrary to clause (2) of article 357 of the Constitution. According to that clause	 "any law made in exercise of the power of the Legislature of the State by Parliament or the President or other authority referred to in sub clause (a) of clause (1) which Parliament or the President or such other authority would not	 but for the issue of a Proclamation under article 356	 have been com petent to make shall	 to the extent of the incompetency	 cease to have effect on the expiration of a period of one year after the Proclamation has ceased to operate except as respects thing done or omitted to be done before the expiration of the said period	 unless the provisions which shall so cease to have effect are sooner repealed or reenacted with or without modification by Act of the appropriate Legislature". The above provision makes it plain that the period for which a law made under article 3 5 6 (I remains in force is not co terminous with the duration of the Proclamation. It has not been disputed that the President was competent under clause (1) of article 356 of the Constitution to enact Act No. 19 of 1970. The said Act	 in view of the provisions of clause (2) of article 357	 shall continue to remain in force in spite of the revocation of the Proclamation dated Mach 19	 1970 and would cease to have effect only on the expiry of on	 	 year after the Proclamation has ceased to operate except as respects things done or omitted to be done before the expiration of the said period	 unless the provisions of the Act are sooner repealed or reenacted with or without modification by Act of the appropriate Legislature. As the aforesaid period of one year has not expired and as the provisions of the Act have not been repealed or re enacted with or without modification by Act of the appropriate Legislature	 the impugned Act should be held to be still in force. In view of our finding that the Act (Act No. 19 of 1970) is still in force	 it is not necessary to consider the question as to what would be the legal position in respect of subsisting detentions after the Act ceases to have effect in accordance with article 357(2) of the Constitution. 228 Argument has then been advanced by Mr. Puri that the im pugned detention order was not in conformity with section 10 of the Act as it did not specify the date of detention. Section 10 reads as under : "10. In every case where a detention order has been made under this Act	 the State Government shall	 within thirty days from the date of detention under the order	 place before the Advisory Board	 constituted by it under section 9	 the grounds on which the order has been made and the representation	 if any	 made by the person affected by the order	 and in case where the order has been made by an officer specified in sub section (3) of section 3	 also the report made by such officer	 under sub section (4) of section 3. " According to the learned counsel	 the words "within thirty days from the date of detention under the order" in the section indicate that it is imperative on the part of the detaining authority to specify the date of detention in the order. We find ourselves unable to accede 'to this submission. All that section 10 contemplates is that the State Government should within 30 days from the commencement of the detention place before the Advisory Board the grounds on which the order has been made and the representation	 if any	 made by the person affected by the order	 and in case where an order has been made by an officer specified in sub section (3) of section 3	 also the report made by such officer under sub section (4) of section 3. There is nothing	 however	 in the section which makes it obligatory on the part of the detaining authority to specify the date of the commencement of detention. Detention starts from the time a detenu is taken into custody in pursuance of the detention order. In most of the cases it may be difficult to state in the detention order as to when the detention WOuld commence because the detaining authority cannot be certain at the time of the making of the detention order about the date on which the person ordered to be detained would be taken into custody. The possibility of the person ordered to be detained avoiding or delaying his apprehension by absconding or concealing himself cannot be ruled out. In case the contention advanced on behalf of the petitioner were to be accept 	 the detention order would cease to be enforceable in case the person. ordered to be detained cannot somehow be apprehended on the date mentioned in the order. We find it difficult to draw such an inference from the language of section 10 of the Act. The words "from the date of detention under the order"	 in our opinion	 have reference to the date of the commencement of the detention in pursuance of the detention order. 229 Lastly	 it has been argued by Mr. Puri that the grounds of detention are not germane to the objects for which a person can be ordered to be detained under the Act. In this connection	 we find that	 according to the grounds of detention which were furnished to the petitioner	 he was being detained as he was acting in a manner prejudicial to the maintenance of public order as evidenced by particulars given below : "On 12 2 71 at about 02.00 hrs. 	 you and some of your associates being armed with bombs and other lethal weapons attacked Shri K. K. Naskar	 I.A.S.	 S.D.O.	 Bongaon and his guard by hurling bombs and thereby causing injuries to the guard constable when they came out on hearing sounds of explosion of bombs near the quarters of Shri section C. Sarkar	 Magistrate 1st Class	 Bongaon	 at Amlapara near Bongaon Court. You	 thereby	 created a panic in the locality and disturbed the public order. (2) On 23 2 71 between 10.45 hrs. and 02.15 hrs Bongaon Police on receipt of a secret information searched a house at Subhaspalli	 Bongaon and recovered 3 high explosive bombs and some explosive materials from you and your associates possession." According to section 3 of the Act	 the State Government may. if satisfied with respect to any person that with a view to preventing him from acting in any manner prejudicial to the security of the State or the maintenance of public order it is necessary so to do	 make an order directing that such person be detained. District Magistrates and some other officers under subsection (3) of section 3 of the Act have been empowered	 if satisfied as provided in sub section (1)	 to exercise the powers conferred by the said sub section. According to clause (d) of sub section (2) of section 3 of the Act	 for the purposes of sub section (1) the expression "acting in any manner prejudicial to the security of the State or the maintenance of public order" inter alia means : "committing	 or instigating any person to commit	 any offence punishable with death or imprisonment for life or imprisonment for a term extending to seven years or more or any offence under the or the 	 where the com mission of such offence disturbs	 or is likely to disturb	 public order. " It is manifest from the above definition that the expression "acting in any manner prejudicial to the maintenance of public order" would include the commission of an offence under the when the commission of such offence disturbs or is likely to disturb public order. Particulars 230 supplied to the petitioner regarding the incident of February 12	 1971 show that the petitioner and his associates hurled bombs near the quarter of the S.D.O.	 Bongaon and caused injuries to his guard	 as a result of which panic was created in the locality and public order was disturbed. The particulars regarding the incident of February 12	 1971 clearly bring the case within ambit of clause (d) of sub section (2) of section 3 of the Act. As regards the second incident of February 23	 1971 we find that the particulars show that three high explosive bombs and explosive materials were recovered from the possession of the petitioner and his associates on search of a house. The particulars thus show that the petitioner was guilty of an offence under the . It is also obvious that the use of high explosive bombs was likely to disturb public order. The fact that the high explosive bombs were	 recovered from the petitioner and his associates and taken into possession before they could be used would not take the case out of the purview of clause (d) The earlier incident of February 12	 1971 gives a clear indication of the propensity of the petitioner to use and explode such bombs. The recovery of the high explosive bombs from the possession of the petitioner prevented him from using and exploding the bombs and disturbing public order. As the object of detention is to prevent the detenu from acting in any manner prejudicial to the security of the State or the maintenance of public order	 the grounds of detention supplied to the petitioner	 in our opinion	 should be held to be germane to the purpose for which detention order can legally be made under the Act. In order to detain 1 person with a view to pit vent him from acting in any manner prejudicial to the security of the State or the maintenance of public order	 as contemplated by section 3 (2) (d) of the Act	 it is sufficient that the detaining authority considers it necessary to detain him in order to preve nt him from doing any of the acts mentioned in clause (d). If the past conduct and antecedents of the person concerned reveal a tendency to do the acts referred to in clause (d)	 the order of detention would be upheld	 even though because of some supervening cause like prompt action by the police	 the public order is not actually disturbed. We	 therefore	 find no infirmity in the impugned detention order. It also cannot be said that the detention of the petitioner is not in accordance with law. The petition consequently fails and is dismissed. K.B.N. Petition dismissed.

The petitioner was detained under section 3 of the West Bengal (Prevention of Violent Activities) Act	 1970 (President 's Act 19 of 1970) as he was acting in a manner prejudicial to the maintenance of public order. The particulars supplied to the	 petitioner showed that he and his associates hurled bombs as a result of which panic was created in the locality and that high explosive bombs were recovered from the possession of the petitioner and his associates. In the petition for the issue of a writ of habeas corpus it was contended on behalf of the petitioner that (1) on the revo cation of the Proclamation under article 356 of the Constitution	 President 's Act No. 19 of 1970 ceased to have effect and	 as such	 the petitioner could not be kept in detention in pursuance of the order made under the Act 	 (ii) the impugned detention order was not in conformity with section 10 of the Act as it did not specify the date of detention and (iii) the ground 	 of detention were not germane to the objects for which a person can be ordered to be detained under the Act. Dismissing the petition	 HELD : (i) The period for which a law made under article 356 (1) remains in force is not co terminous with the duration of the proclamation. In view of the provisions of clause (2) article 357	 President 's Act 19 of 1970 shall remain in force in spite of the revocation of the proclamation and would cease to have effect only on the expiry of one year after the proclamation has ceased to operate unless the provisions of the Act are sooner repealed or reenacted by Act of the appropriate State Legislature. [227E] (ii) There is nothing in section 10 which makes it obligatory on the part of the detaining authority to specify the date of the commencement of the detention : The words "from the date of detention tinder the order" have reference to the date of the commencement of the detention in pursuance of the detention order. [228E F] (iii) According to cl. (d) of sub section (2) of section 3 the expression "acting in any manner prejudicial to the maintenance of public order" would include commission of an offence under the 	 or the . The particulars supplied to the petitioner clearly bring the case within the ambit of clause (d) of subsection (2) of section 3 of the Act. [229H] In order to detain a person with a view to preventing him from acting in any manner prejudicial to the security of the state or the maintenance of public order	 as contemplated by section 3 (2) (d) of the Act	 it is sufficient. 225 that the detaining authority considers it necessary to detain him in order to prevent him from doing any of the acts mentioned in clause (d). If the past conduct and antecedents of the person concerned reveal a tendency to do the acts referred to in clause (d)	 the order of detention would be upheld	 even though because of some supervening cause like prompt action by the police	 the public order is not actually disturbed.
