Summarize the following court judgment. Criminal Appeal No. 219 of 1990. 214 WITH Writ Petition (Crl.) No. 92 of 1990. From the Judgment and Order dated 12.12.1989 of the Allahabad High Court in Habeas Corpus W.P. No. 13644 of 1989. A. Jaitley	 Additional Solicitor General	 R.K. Jain	 Yogeshwar Prasad	 Gaurav Jain	 Abha Jain	 D. Bhandari	 Ms. A. Subhashini and R.B. Misra for the Appearing Parties. The Judgment of the Court was delivered by section RATNAVEL PANDIAN	 J. Leave granted in the Special Leave Petition. This appeal is against the judgment and order dated 12.12.89 in Habeas Corpus Writ Petition No. 13644/89 passed by the High Court at Allahabad dismissing the writ petition filed by the appellant	 Vashisht Narain Karwaria	 the detenu herein. The District Magistrate	 Allahabad	 in exercise of powers conferred on him under Section 3(3) of the (hereinafter referred to as 'Act ') passed the impugned order of detention on 31.3.88 against the detenu on reaching his requisite subjective satisfaction on consideration of the materials placed before him that it had become necessary to pass the detention order with a view to preventing the detenu from acting in any manner prejudicial to the maintenance of public order. The salient and material facts which necessitated the detaining authority to pass the impugned order	 as set out in the grounds of detention are as follows: On 30.3.1988 at about 3.30 P.M. the auction of liquor shops for the sale of Indian made foreign liquor was held in the campus of Collectorate at Allahabad. A large number of bidders were present. Among them	 the detenu along with his three other associates also participated in the auction. At about 3.30 P.M. the auction of the liquor shop within the area of Mooratganj took place. For this shop the first bid was from one Ajai Kumar for Rs. one lakh. The next bid for the same shop was of Chedi Lal for Rs. one lakh and ten thousand. The moment the said two persons made their bid	 the detenu along with his associates stood UP in 	the 	presence of all prospective bidders and told Ajai Kumar	 Chedi Lal and others that the above said shop fell within his area and	 therefore	 if anybody dared to bid the shop in the auction he Would shoot him and also the entire members of his 215 family. So saying the detenu along with his associates advanced towards Ajai Kumar and Chedi Lal threatening them with dire consequences. This created terror and panic among all the bidders. As the situation was becoming worse	 Shri Rana Pratap Singh	 Station House Officer along with other police officials advanced towards the detenu and his associ ates to apprehend them. On seeing the police party advanc ing	 the detenu fired at the police party with his country made pistol. Fortunately	 no body was hurt. The detenu	 however	 escaped on being chased by the police party. The detenu fired another two shots and hurled bombs on the police party while fleeing away. His repeated firing and explosion of bombs created further panic and the people assembled for bidding the auction started running away and the nearby shopkeepers pulled down their shutters of their shops. The vehicles parked there fled away. Thus the public order was completely disrupted. In connection with this incident	 a case was registered in crime No. 221/88 in the Colenolganj Police Station under Section 307 and 506 of Indian Penal Code. The case is still under investigation. On the basis of the above material the detaining author ity on being satisfied that there was apprehension of com mission of act of violence at the hands of the detenu	 which would be prejudicial to the maintenance of public order	 passed this impugned order and directed the detenu to be kept under detention. Admittedly	 along with his ground of detention 4 docu ments were enclosed and served on the detenu. Those docu ments are: (1) Report of S.S.P. Allahabad dated 31.3. (2) Report of the S.H.O. Colenolganj Police Station. (3) Copy Chik No.199	 Crime No. 221 of 1988 under Section 307/506 I.P.C. in Colenolganj Police Station	 Allahabad. (4) Copy of G.D. No. 37 relating to the aforesaid offence. The detenu challenged the validity of this order before the High Court	 but became unsuccessful. Feeling aggrieved by the impugned judgment	 this appeal is now preferred. Mr. R.K. Jain	 the learned Sr. counsel appearing on behalf of the appellant made a number of submissions at the hearing	 one of which being that the sponsoring authority had placed 216 certain irrelevant and extraneous matters before the detain ing authority which should have influenced the mind of the detaining authority and stealthily crept into the decision of the said authority directing detention of the detenu and as such the impugned order is liable to be quashed. This argument was resisted by Shri Dalveer Bhandari	 the learned counsel appearing on behalf of the respondents that the detaining authority had not considered any other material save the material referred to in the grounds of detention '. Therefore	 the short question for our consideration is whether the sponsoring authority has placed before the detaining authority any extraneous and irrelevant materials which might have influenced the mind of the detaining au thority. It cannot be disputed indeed there is none that the four documents referred to above	 copies of which were furnished to the detenu have been placed before the detain ing authority. It follows that the detaining authority passed this order only on consideration of the above said materials. In the confidential letter dated 31st March 1988 sent by the Senior Superintendent of Police	 Allahabad to the detaining authority it is stated thus: "It is stated that the accused is a hardened criminal and has a gang. Such persons are committing heinous crimes often which adversely affects the public order. There are many cases/offences against accused Vashistha narayan registered in various police stations. It has become his habit to commit offences . . Hence I recommend that an order for atleast 12 months detention be passed against Shri Vashisht Narayan Karwaria alias Bhukkhal son of late Shri Jagat Narayankarwaria	 the aforesaid accused under Section 3(2) of the above mentioned Act. " The preamble of the letter submitted by the Station House Officer of Colenolganj	 Allahabad dated 31.3. 1988 to the Senior Superintendent of Police	 Allahabad reads as follows: "It is submitted that Shri Vashisht Narayan Karwaria alias Bhukkal	 the aforesaid accused is a hardened criminal and has a gang. In his gang his son Kapil and two other big offenders Ram Chandra Tripathi and Santosh Kumar Tripathi son of Gaya Prasad	 resident of Ganspur	 P.S. Poormufti	 District Allahabad	 are included. These 217 people often used to commit heinous crimes	 by which terror and fear prevails in the people. Many crimes are registered against Vashisht Narayan Karwaria in many Police Stations. " The above averments made in the above two letters	 the copies of which are furnished to the detenu along with grounds of detention unequivocally and clearly spell out that the detenu is a hardened criminal	 having a gang under his control often committing heinous crimes	 that many cases against the detenu are registered in various police stations and that he is in the habit of committing offences. No doubt	 these averments are not made mention of in the grounds of detention. But can it be said that these materi als placed before the authority might not have influenced the mind of the detaining authority in taking the decision of detaining the detenu? In our view	 the above averments which are extraneous touching the character of the detenu though not referred to in the Grounds of detention	 might have influenced the mind of the detaining authority to some extent one way or other .in reaching the subjective satis faction to take the decision of directing the detention of the detenu. As rightly pointed out by Mr. Jain	 had these extraneous materials not been placed before the detaining authority	 he might or might not have passed this order. Therefore	 we have to hold that the detention order is suffering from the vice of consideration of extraneous materials vitiating the validity of the order. There are several pronouncements of this Court	 on this point	 of which we will make mention of to the following decisions: Ram Krishna Paul vs The Government of West Bengal & Ors.	 ; Smt. Pushpa vs Union of India & Others	 [1980] Supp. SCC 39 1; Merugu Satyanarayana vs State of Andhra Pradesh & Ors.	 1 and Mehboob Khan Nawab Khan Pathan vs Police Commissioner	 Ahmedabad and Another	 Mr. Dalveer Bhandari relying on Section 5A of the Act urged that the order of detention should not be deemed to be invalid or inoperative merely on the ground that some extra neous materials were placed before the detaining authority since those alleged extraneous materials have no bearing on the validity of this impugned order which can be sustained on the material set out in the Grounds of detention itself. Placing reliance on decision of this Court in Prakash Chan dra Mehta vs Commissioner and Secretary	 Govt. of Kerala and Others	 [1985] Supp. SCC 144 wherein it has been observed that the 'grounds ' under Article 22(5) of the Constitution do not mean mere factual 218 inferences but mean factual inferences plus factual material submitted that in the present case the factual material set out in the grounds of detention alone led to the passing of the order with a view to preventing the detenu from acting in any manner prejudicial to the maintenance of public order. We are unable to see any force in the above submis sion. What Section 5A provides is that where there are two or more grounds covering various activities of the detenu	 each activity is a separate ground by itself and if one of the grounds is vague	 nonexistent	 not relevant	 not con nected or not proximately connected with such person or invalid for any other reason whatsoever	 then that will not vitiate the order of detention. It is not the case that this impugned order has been made on the two or more grounds covering various activities of the detenu	 but on the other hand the order has been passed on the sole ground relatable to a single incident. The conclusion arrived at by us is only on the basis that the aforesaid extraneous materials	 placed before the de taining authority might have influenced the mind of the detaining authority	 but not on the ground that one of the grounds of the detention order has become invalid or inoper ative for the reasons mentioned in Section 5(A)(a). The next submission made by Mr. Jain on behalf of the detenu is on the basis of Ground Nos. VII & VIII of the Special Leave Petition in which the appellant has expressed his grievance that he had been deprived of making an effec tive and purposeful representation as envisaged under Arti cle 22(5) of the Constitution of India since no particulars or details are given in documents I & H enclosed with the grounds of detention in regard to the alleged 'many cases/offences ' said to have been registered in various police stations against him and in regard to the allegations that he was a hardened criminal and had a gang often commit ting heinous crimes and that it had become the habit of the detenu to commit offences. In support of this contention reference was made to the decision in Mehboob Khan Nawab Khan Pathan 's case (ibid). No denial is made in the counter filed on behalf of the first respondent. This latter submis sion	 in our opinion	 cannot be rejected as having no force. In the result	 we without going into the merits of the other contentions allow this appeal	 quash the detention order and direct the detenu to be set at liberty forthwith. 219 ORDER The Writ Petition is connected with the Criminal Appeal No. 219 of 1990 arising out of SLP (Crl.) No. 2473/89. The detention order under challenge in both the proceedings is the one passed by the District Magistrate	 Allahabad on 31.3.1988 under Section 3(.3) of the . As we have now set aside the order of detention in the Criminal Appeal	 no order is necessary in this Writ Peti tion. The Writ Petition is disposed of accordingly. T.N.A. Appeal allowed and Petition disposed of.

The petitioner was detained under section 3(3) of the 	 under an order passed by the detaining authority after consideration of the documents placed before it by the sponsoring authority alleging that the detenu was a hardened criminal and habitual offender against whom many cases were registered. The documents placed before the detaining authority were also served on the detenu along with the ground of detention. The appellant filed a writ of Habeas Corpus in the High Court challenging the validity of the detention which was dismissed. Hence this appeal. The appellant also filed a writ petition in this Court challenging his detention. In this appeal it was contended on behalf of the appellant that the detaining authority had acted on irrelevant and extrane ous matters therefore the detention order is liable to be quashed. On behalf of the respondent it was contended that the order of detention was not invalid merely because some extraneous materials were placed before the detaining au thority since the impugned order could be sustained on the material set out in the grounds of the detention itself. Allowing the appeal and disposing the Writ Petition	 this Court	 213 HELD: 1. The averments made in the documents	 the copies of which are furnished to the detenu along with grounds of detention unequivocally and clearly spell out that the detenu is a hardened criminal	 having a gang under his control often committing heinous crimes	 that many cases are against the detenu are registered in various police stations and that he is in the habit of committing offences. These averments which are extraneous touching the character of the detenu though not referred to in the grounds of detention	 might have influenced the mind of the detaining authority to some extent one way or other in reaching the subjective satisfaction to take the decision of directing the detention of detenu. Had these extraneous materials not been placed before the detaining authority	 he might or might not have passed this order. Therefore the detention order is suffer ing from the vice of consideration of extraneous materials vitiating the validity of the order. detention order is therefore quashed. [217B E] Ram Krishna Paul vs The Government Of West Bengal & Ors.	 ; ; Smt. Pushpa vs Union of India & Ors.	 [1980] Supp. SCC 391; Merugu Satyanarayana vs State of A.P. & Ors.	 ; and Mehboob Khan Nawab Khan Pathan vs Police Commissioner	 Ahmedabad & Anr.	 ; followed. Section 5A provides that where there are two or more grounds covering various activities of the detenu	 each activity is a separate ground by itself and if one of the grounds is vague	 non existent	 not relevant	 not connected or not proximately connected with such person or invalid for any other reason whatsoever	 then that will not vitiate the order of detention. In the instant case the impugned order has not been made on two or more grounds covering various activities of the detenu. but has been passed on the sole ground relatable to a single incident. The conclusion ar rived at is only on the basis that the extraneous materials placed before the detaining authority might have influenced the mind of the detaining authority	 but not on the ground that one of the grounds of the detention order has become invalid or inoperative for the reasons mentioned in Section 5(A)(a). Therefore the submission that the factual material set out in the grounds of detention alone led to the passing of the order with a view to preventing the detenu from acting in any manner prejudicial to the public order is not correct.
