Summarize the following court judgment. No. 205 of 1971. Petition under article 32 of the Constitution of India for a writ in the nature of habeas corpus. 518 V. Mayakrishnan	 for the petitioner. section P. Mitra	 G. section Chatterjee for Sukumar Basu	 for the respondent. The impugned order states that the District Magistrate was satisfied that it was necessary that the petitioner should be detained with a view to prevent him from acting in any manner prejudicial to the security of the State or the maintenance of public order as provided by section 3(1) of the Act. According to the affidavit in reply of the District Magistrate	 he reported under section 3 (4) of the Act to the State Government On March 3	 1971 regarding the fact of his having passed the order of detention together with the grounds of detention and all other. particulars having a bearing on the name. It is further stated that the. petitioner was arrested on March 5	 1971 and was served on the same day with the order of detention together with the	 grounds for passing the order of detention. The petitioner was also informed that he is entitled to make a representation to the State Government against the order of detention and that such representation is to be addressed to the Assistant Secretary Home (Special) DEpartment	 Government of West Bengal and forwarded through the Superintendent of Jail. He was further informed that his case will be placed under section 10 of the Act before	 the Advisory Board within 30 days from the date of the order of detention. He was also informed that under section 11 of the Act	 the; Advisory Board shall	 if so desired by him	 hear him in person and that the petitioner must intimate the said desire to be heard in the representations that he may make to the State Government. The State Government considered the report of the District Magistrate together with other materials placed before it and approved	 on March 11	 1971 as required by section 3 (4) of the Act	 the order of detention passed by the District Magistrate. On the same day	 as required	by section 3(5) the State Government sent the necessary report to the Central Government. The State Government on April 3	 1971 placed the case of the petitioner before the Advisory Board. 519 The petitioner sent two representations dated March 17	 and April 19	 1971 denying the allegations made in the grounds for passing the order of detention and pleaded that he was innocent. He has admitted in these representations that he was arrested on March 5	 1971. In neither of these representations did the petitioner make a request that he should be provided an opportunity of being heard in person by the Advisory Board. The State Government rejected the representations of the petitioner	 but forwarded them to the Advisory Board for being considered. The Advisory Board after considering the	 materials placed before it relating to the detention of the petitioner including the represen tations made by him on March 17	 1971 and April 19	 1971	 submitted its report on May 11	 1971 to the State Government stating that it is of opinion that there is sufficient cause for the detention of the petitioner. The State Government passed an order on July 12	 1971 under section 12(1) of the Act confirming the order: of detention dated March 2	 1971 passed by the District Magistrate and directed that the petitioner 's detention shall be continued till the expiration of twelve months from the date of his detention. The petitioner has challenged the order of detention on the ground that he has never committed any offence nor has he been involved in any illegal activities as alleged in the grounds of detention. He has further stated that the various allegations mentioned against him are false and that he never participated in any of the incidents referred to in the grounds of detention. The petitioner has further stated that he is innocent and that he has been illegally detained. It Will be noted from his averments in the writ petition that except denying that the allegations are false and that he has never participated in any of those incidents referred to in the grounds of detention	 he has not alleged any mala fides nor challenged the jurisdiction of the officer who	 passed the order of detention or the various proceedings connected therewith. Under section 3 (1) of the Act	 *hat is required is the satisfaction of the State Government or the relevant District Magistrate	 as the case may be	 of the necessity to detain a person with a view to prevent him from acting in a manner prejudicial to the security of the State or the maintenance of public order. In the order of detention dated March 2	 1971	 the District Magistrate has stated that he was satisfied that with a view to prevent the petitioner from acting in any manner prejudicial to the security of the State or the maintenance of public order	 it is necessary to detain the petitioner and that the order was being passed in exercise of the powers conferred on the District Magistrate by sub section (1) read with subsection (3) of section 3 of the Act. In the grounds of detention 520 . furnished to the petitioner on March 5	 1971 along with the order dated March 2	 1971 the following particulars have been given: "(1) That	 on 26 1 71 between 11.00 and 12.31 hours	 you along with your associates being armed with bombs	 ballasts	 pipe guns	 lathis etc.	 assembled at Piali Railway Station and created terror among the passengers by charging bombs and showering ballasts indiscriminately and also moving from compartment to compartment of train Nos. SC 193 UP and SC 195 UP in search of your rivals	 shouting that "if I get the Rascal	 I will kill them" and in doing so you caused injury to some innocent passengers and broke the glass panes of driver 's cab of SC 195 Up. You created disturbance of the public order thereby. (2)That	 on 2 2 71 at about 17.39 hours	 you along with your associates	 being armed with bombs	 daggers etc.	 attacked and assaulted the guard of train No. SC 199 Up at Champahati Railway Station and also created terror among the passengers by charging a bomb. You created disturbance of the public order thereby. (3) That on 9 2 71 at about 13.15 hours you and your associates charged bombs and ballasts on duty Police party at Jadavpur Railway Station as they seized 10 bags of rice weighing about 3 quintals from SC 195 Up	 while you were taking the said stock to Calcutta rationing area illegally by train. Your attack grew so violent that the Police party had to open fire upon you in self defence. Your violent activities created serious panic in the Station area and the public order was disturbed thereby. " In the two representations dated March 17 and April 19	 1971 made to the State Government	 the petitioner after referring to the fact that he was arrested on March 5	 1971 has denied that he was involved in any of the types of violent activities referred to in the grounds for detention. He has further stated that he is leading a very honest life doing the work of mason and that the allegations made against him are false. As we have already mentioned	 the petitioner did not ask for an opportunity of. being heard	in person by the Advisory Board. He has not also alleged in these representations and mala fides in passing the order of dention. The District Magistrate who passed the order of detention has filed a counter affidavit. The District Magistrate has stated that the petitioner is rice smuggler operating in Subarban Railway 521 trains in Southern Section of Eastern Railway and that he along with his associates armed with bombs and other deadly weapons attacked the passengers and the guard of railway trains and created terror by hurling bombs in Champahati and Piali Railway Stations. The District Magistrate further proceeds to state that the petitioner was detained for acting in a manner prejudicial to the security of the State or the maintenance of public order in the Jadavpur area of the district of 24 Parganas for his having taken a leading and active part in violent activities. It is further stated in the counter affidavit that the activities of the petitioner disturbed the public order and were so persistent and violent that he became a terror to the residents of the locality and the railway traveling public and that but for his detention he could not have been prevented from acting in a manner prejudicial to the security of the State 	or maintenance of public order. It is further stated that the deponent after receiving reliable information relating to the anti social and prejudicial activities of the petitioner and after carefully considering these materials	 he was fully satisfied that the petitioner was engaged and was indulging in activities which were prejudicial to the security of the State or the maintenance of public order	 and that his detention was essential. On being thus satisfied	 the District Magistrate proceeds to state that he bona fide passed the order of detention on his own satisfaction	 judgment and reasoning. The counter affidavit then proceeds to state about the order of confirmation passed by the State Government and other matters resulting finally in the order passed by the Government on July 12	 1971. It may be pointed out that in paragraph 6 of the counter affidavit it has been mentioned that the Advisory Board submitted its report on May 11	 1971 "after hearing the petitioner. " This statement is obviously wrong because the petitioner never asked for being heard in person. The Advisory Board also does not say that the petitioner was heard in person. The counsel appearing for the State has expressed his regret regarding this mistaken averment made in the counter affidavit. But that does not in any manner advance the case of the petitioner	 as we will presently show. We have already referred to the fact that the petitioner has merely denied his being associated with the incidents. referred to in the grounds of detention. We are satisfied from the averments made by the District Magistrate in the counter affidavit	 which have not been further controverted by the petitioner by filing any rejoinder that the order of detention has been validly and properly passed. Mr. V. Mayakrishnan	 Amicus Curiae	 appearing on behalf of the petitioner has urged that every one of the grounds has referred to the activities of the petitioner having resulted in disturbance of 522 public order. But the order of detention refers to the fact that the District Magistrate was of the view that the petitioner should be detained with a view to preventing him from acting in any manner prejudicial to the security of the State or the maintenance of public order. No ground showing as to how any activity of the petitioner is prejudicial to the security of the State justifying the order Of detention has been furnished to the petitioner. Therefore	 according to the learned counsel	 the order of detention is illegal inasmuch as the petitioner has not been informed of any grounds as to how his activities are prejudicial to the security of the State. Inasmuch as both the matters have been mentioned in the order of detention	 it must be that the detaining authority has taken into account extrenuous and irrelevant matters in passing the order of detention. In particular	 according to the learned counsel	 it is only the matters referred to in sub cl. (1) of cl. (a) of section 3 (2) of the Act that will relate to the activities adversely affecting the security of the State. None of those matters have been mentioned in the grounds furnished to the petitioner. Therefore	 it is not clear whether the detaining authority passed the order to prevent the petitioner from acting in any manner prejudicial to the Security of the State or for maintenance of public order. For all these	 reasons	 the counsel urged	 the order of detention is illegal. Mr. section P. Mitra	 learned counsel appearing for the State drew our attention to the provisions contained in section 3(2) of the Act and pointed out that the various acts mentioned in the grounds of detention come within the expressions "acting in any manner prejudicial to the security of the State or the maintenance of public order." In particular he relied upon cl. (d) of section 2 and pointed out that the petitioner has committed an offence under the 	 (Act No. 6 of 1908) and	 therefore	 his detention was legal. We are not inclined to accept the contention of the learned counsel for the petitioner. As already mentioned	 under section 3(1) of the Act	 what is required is the satisfaction of the State Government or the relevant District Magistrate	 as the case may be	 of the necessity to detain a person with a view to prevent him from acting in a manner prejudicial to the security of the State or the maintenance of public order. As defined by sub section (2) of section 3	 the expression "acting in any manner prejudicial to the security of the State or the maintenance of public order means : lm15 "(a)using or instigating any person by words	 either spoken or written	 or by signs or by visible representations or otherwise	 to use	 any lethal weapon (i) to promote or propagate any cause or ideology the promotion or propagation of which affects 523 or is likely to affect	 adversely the security of the State or the maintenance of public order. or (ii)to overthrow or to overawe the Government established by law in India. Explanation In this clause	 "lethal weapon" includes fire arms	 explosive or corresive substances. swords	 spears	 daggers	 bows and arrows; or (b)committing mischief	 within the meaning of section 425 of the Indian Penal Code	 by fire or any explosive substance on any property of Government or any local authority or any corporation owned or controlled by Government or any University or other educational institution or on any public building	 where the commission of such mischief disturbs	 or is likely to disturb	 public order; or (c)causing insult to the Indian National Flag or to any other object of public veneration	 whether by mutilating	 damaging	 burning	 defiling	 destroying or otherwise	 or instigating any person to do so. Explanation In this clause	 "object of public veneration" includes any portrait or statute of an eminent Indian	 installed in a public place as a mark of respect to him or to his memory; or (d)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 commission of such offence disturbs	 or is likely to disturb	 public order; or (e)in the case of a person referred to in clause (a) to (f) of section 110 of the Code of Criminal Procedure	 1898	 committing any offence punishable with imprisonment where the commission of such offence disturbs or is likely to disturb	 public order. It will be seen that the Act itself furnishes a dictionary meaning. for the two expressions and a perusal of cls. (a) to (e) clearly shows that any of the matters referred to therein will be both " prejudicial to the security of the State or the maintenance of public order". We are not inclined to accept the contention on behalf of the petitioner that it is only sub cl. (1) of cl. (a) of section 3(2) which 524 deals with the matters	 which adversely affect the security of the 	State. In fact that very sub clause refers to the 'matters mentioned therein as affecting the security of the State or the maintenance of public order. Therefore	 in this case the grounds of detention .cannot be held to be vague nor can the order of detention be held to be invalid on the ground that the petitioner must have been detained only to prevent him from acting in any manner prejudicial to the maintenance of public order and not to the security of the State. In particular	 under cl. (d) of section 2	 a person will be considered to be acting in a manner prejudicial to the security of the State or the maintenance of public order	 if he commits any offence under the . The various incidents mentioned in the grounds of detention may also come under cl. (b) of sub section (2) of section 3 Section 3 of the 	 is as follows : "Sec. 3 : Any person who unlawfully and mali ciously causes by any explosive substance an explosion of a nature likely to endanger life or to cause serious injury to property shall	 whether any injury to person or property has been actually caused or not	 be punished with transportation for life or any shorter term	 to which fine may be added	 or with imprisonment for a term which may extend to ten years	 to which fine may be added." ' The various grounds mentioned in the order of detention clearly bring the activities of the petitioner under section 3 quoted above. The date and the place as well as the time when the incidents occurred	 and also the train numbers which were affected	 as well as the association of the petitioner with those incidents	 have been fully given in the grounds of detention. No doubt the names of the persons	 who are stated to be his associates have not been given. For all the above reasons	 we are satisfied that the order of detention is valid. In the result	 rule nisi is discharged and this writ petition dismissed. G.C. Petition dismissed.

The petitioner was detained under an order dated March 2	 1971 passed by the District Magistrate	 24 Pargana	 West Bengal	 under sub section (i) read with sub section (3) of section 3 of the West Bengal (Prevention of Violent Activities) Act	 1970. The order stated that the District Magistrate was satisfied that it was necessary that the petitioner should be detained with a view to prevent him from acting in any manner pre judicial to the security of the State or the maintenance of public order as provided in section 3(1). In the grounds of detention supplied to the petitioner three incidents of violence at railway stations in which the petitioner was alleged to have participated and used explosives were men tioned. In his representations against being detained the petitioner did not allege any mala fides against the administration but only denied that he took part in the violent activities. In 'support of the writ petition under article 32 of the Constitution challenging the order of its detention it was urged that while the impugned order mentioned his activities as being prejudicial to public order as well as security of the State	 the instances given in the grounds of detention only mentioned activities pre judicial to public order. The detaining authority had thus taken into account extraneous and irrelevant matters in passing the order of detention. ' According to the appellant it is only matters referred to in sub c. (i) of c1. (a) of section 3(2) of the Act which will relate to the activities adversely affecting the security of the State	 and none of these matters had been mentioned in the grounds of detention furnished to the petitioner. HELD : The contention of the petitioner that it is only sub cl. (1) of cl. (a) of section 3(2) which deals with matters adversely affecting the security of the State could not be accepted. In fact that very sub clause refers to the matters herein as affectingthe security of the State or the maintenance of public order. Thereforein this case the grounds of detention could not be held to be vague norcould the order of detention be held to be invalid on the ground thatthe petitioner must have been detained only to prevent him from actingin any manner prejudicial to the maintenance of public order and not to the security of the State. In particular under cl. (d) of section 2 a person will be considered to be acting in a manner prejudicial to the security of the State or the maintenance of public order	 if he commits any offence under the . The various incidents mentioned in the grounds of detention may also come under cl. (b) of sub section '(2) of section 3. Further the said grounds clearly bring the activities of the petitioner under section 3 of the . [523 H 524 E] Accordingly the detention of the petitioner must be held to be valid and the petition under article 32 must be dismissed.
