Summarize the following court judgment. N: Criminal Appeal No. 193 of 1979. From the Judgment and Order dated 23 1 1979 of the Gujarat High Court in Special Criminal Application No. 8/79. P. H. Parekh and M. Mudgol for the Appellant. N. M. Phadke	 section P. Nayyar and M. N. Shroff for the Respondent. The Judgment of the Court was delivered by CHINNAPPA REDDY	 J. Kanchanlal Maneklal Chokshi who is in preventive detention under the provisions of the and whose petition for the issue of a writ of Habeas Corpus was rejected by the High Court of Gujarat is the appellant in this appeal. The High Court	 while rejecting the petition	 granted a certificate under Article 133(1) of the Constitution that the case involved a substantial question of law of general importance which needed to be decided by the Supreme Court. The substantial question of law so certified was 'whether it is necessary for the detaining authority to consider whether a person should be prosecuted before an order of detention is made against him '. The Division Bench of the Gujarat High Court in rejecting the particular contention of the appellant 5 475 SCI/79 56 purported to follow an earlier decision of another Division Bench of the same Court in Ashok Murlidhar vs State of Gujarat.(1) In that case Divan C. J.	 and Majumdar	 J.	 though inclined to the view that the possibility of a criminal prosecution being launched should be present to the mind of the detaining authority	 felt constrained to hold otherwise because of what	 they thought had been decided by this Court in Hardhan Saha & Anr. vs State of West Bengal & Ors.(2). In our view	 this Court did not say in Hardhan Saha vs State of West Bengal that the possibility of a prosecution being launched was an irrelevant consideration which need never be present to the mind of the detaining authority. On the other hand	 we do not also think that it is axiomatic	 as sought to be contended by the learned Counsel for the appellant	 that the detaining authority must invariably consider the possibility of launching a prosecution before making an order of detention and that	 if not	 the order of detention must necessarily be held to be bad. In Hardhan Saha vs State of West Bengal	 the vires of the provisions of the Maintenance of Internal Security Act was in question. One of the contentions was that Section 3 of the Act offended Article 14 of the Constitution as it permitted 'the same offence to be a ground for detention in different and discriminatory ways '. It was submitted that while A might be prosecuted but not detained preventively	 might not be prosecuted but only detained preventively and C might be both prosecuted and detained preventively. Dealing with the contention	 a Bench of five judges of this Court explained the basic distinction between preventive detention and detention following upon conviction and observed: "The power of preventive detention is qualitatively different from punitive detention. The power of preventive detention is precautionary power exercised in reasonable anticipation. It may or may not relate to an offence. It is not a parallel proceeding. It does not overlap with prosecution even if it relies on certain facts for which prosecution may be launched or may have been launched. An order of preventive detention may be made before or during prosecution. An order of preventive detention may be made with or without prosecution and in anticipation or after discharge or even acquittal. The pendency of prosecution is no bar to an order of preventive detention. An order of preventive detention is also not a bar to prosecution". 57 The Court then referred to various earlier decisions and deduced the following principles: "First merely because a detenu is liable to be tried in a criminal court for the commission of a criminal offence or to be proceeded against for preventing him from committing offences dealt with in Chapter VIII of the Code of Criminal Procedure would not by itself debar the Government from taking action for his detention under the Act. Second	 the fact that the police arrests a person and later on enlarges him on bail and initiates steps to prosecute him under the Code of Criminal Procedure and even lodges a first information report may be no bar against the District Magistrate issuing an order under the preventive detention. Third	 where the concerned person is actually in jail custody at the time when an order of detention is passed against him and is not likely to be released for a fair length of time	 it may be possible to contend that there could be no satisfaction on the part of the detaining authority as to the likelihood of such a person indulging in activities which would jeopardise the security of the State or the public order. Fourth	 the mere circumstance that a detention order is passed during the pendency of the prosecution will not violate the order. Fifth	 the order of detention is a precautionary measure. It is based on a reasonable prognosis of the future behaviour of a person based on his past conduct in the light of the surrounding circumstances". Clearly	 the Court did not lay down that the possibility of a prosecution being launched was an irrelevant consideration	 not to be borne in mind by the detaining authority. All that was laid down was that the mere circumstance that a detenu was liable to be prosecuted was not by itself a bar to the making of an order of preventive detention. It does not follow therefrom that failure to consider the possibility of a prosecution being launched cannot ever lead to the conclusion that the detaining authority never applied its mind and the order of detention was	 therefore	 bad. In Bhutnath Mate vs State of West Bengal(1) Krishna Iyer and Sarkaria JJ.	 declared the detention illegal for denial of opportunity to make effective representation. On the question whether the failure of criminal prosecution was a bar to preventive detention the answer was a definite 'no '. The learned judges however expressed 58 apprehension against the danger to the democratic way of life inherent in 'the potential executive tendency to shy at Courts for prosecution of ordinary offences and to rely generously on the easier strategy of subjective satisfaction '. The question presently under consideration	 namely	 whether the failure of the detaining authority to keep in mind the possibility of a prosecution would necessarily vitiate the order of detention was not considered by the learned judges. In Srilal Shaw vs State of West Bengal & Ors.(1)	 the prosecution was dropped and thereafter an order of preventive detention was passed. The substance of the allegation against the detenu was that he was in unlawful possession of scrap metal belonging to the Railway. The Court came to the conclusion that on the material which was available to the detaining authority	 it was impossible to arrive at the conclusion that the possession of the petitioner was unlawful. The Court found that the reason given by the District Magistrate for dropping the prosecution was unacceptable. It was observed that the prosecution was in all probability dropped as the petitioner might have been able to establish that his possession of the goods was not unlawful. The case struck the Court as a typical case in which for no apparent reason a person who could easily be prosecuted under the punitive law was being preventively detained. It is seen that the decision turned on the peculiar facts of the case and throws no light on the question presently raised before us. In Abdul Gaffer vs State of West Bengal(2) the order of detention was passed on the basis of a few instances of theft of Railway property for which the detenu could well and easily have been prosecuted. The contention before the Court was that the order of detention was passed by the detaining authority mechanically without applying its mind to the question whether the facts disclosed the tendency of the petitioner to act prejudicially in the manner mentioned in the detention order. The bald and sweeping allegation was made in the counter filed on behalf of the State that material witnesses were afraid of giving evidence in the Court against the detenu. The material witnesses were members of the Railway Protection Force. In that situation Sarkaria J.	 observed that the version given in the counter was incredible and could not be swallowed. The learned Judge then observed "the conclusion therefore is inescapable that the petitioner has been proventively detained without application of mind as to whether the prosecution against him was foredoomed to failure on the ground of witnesses being afraid to depose against the detenu 59 in Court. The impugned order has been made in a casual and cavalier manner". It is seen that there was an express allegation that recourse was had to preventive detention despite the fact that criminal prosecutions could well have been successfully launched	 based as the case was on the evidence of members of the Railway Protection Force. The reason given by the State for taking recourse to preventive detention was found to be fantastic. The decision thus stands on the special facts of the case. In Dulal Roy vs The District Magistrate	 Burdwan & Ors.	(1) the Court had to consider a situation where a month after a person was arrested in connection with a criminal case he was discharged but was taken into custody on the same day pursuant to an order of detention. Krishna Iyer and Sarkaria	 JJ.	 while observing that as an abstract legal proposition an order of preventive detention could be validly passed against a person in jail custody on the same facts on which he was being prosecuted for a substantive offence in a Court	 pointed out that such an order of detention was readily vulnerable to the charge that the detaining authority was taking recourse to preventive detention in order to circumvent the penal law and the process of the Court. The learned Judges were satisfied that the discharge of the detenu in a criminal case was not due to any shortcoming in the evidence or difficulty in its production in Court. The order of detention was	 therefore	 quashed on the ground of non application of mind by the detaining authority. In Salim vs State of West Bengal	(2) Chandrachud J.	 speaking for the Court observed that the fact that the detenu could have been prosecuted for the acts attributed to him did not affect the validity of the order of preventive detention. The further question whether it was incumbent on the detaining authority to consider the question of possibility of prosecution was not considered by the Court. In Ashok Murlidhar vs State of Gujarat	 (supra) Divan C.J.	 and Majumdar	 J.	 appeared to think that the Bench of five Judges of this Court which decided Hardhan Saha & Anr. vs State of West Bengal & Ors. 	 (supra) had taken a view different from that expressed in Bhuthnath Mate vs State of West Bengal	 Abdul Gaffer vs State of West Bengal	 Srilal Shaw vs State of West Bengal & Ors.	 Dulal Roy vs The District Magistrate	 Burdwan & Ors. 	 (supra) We do not think that there is any such conflict as thought by the Division Bench of the Gujarat High Court. The principles emerging from a review of the 60 above cases may be summarised in the following way: The ordinary criminal process is not to be circumvented or short circuited by ready resort to preventive detention. But	 the possibility of launching a criminal prosecution is not an absolute bar to an order of preventive detention. Nor is it correct to say that if such possibility is not present to the mind of the detaining authority the order of detention is necessarily bad. However	 the failure of the detaining authority to consider the possibility of launching a criminal prosecution may	 in the circumstances of a case	 lead to the conclusion that the detaining authority had not applied its mind to the vital question whether it was necessary to make an order of preventive detention. Where an express allegation is made that the order of detention was issued in a mechanical fashion without keeping present to its mind the question whether it was necessary to make such an order when an ordinary criminal prosecution could well serve the purpose	 the detaining authority must satisfy the Court that that question too was borne in mind before the order of detention was made. If the detaining authority fails to satisfy the Court that the detaining authority so bore the question in mind the Court would be justified in drawing the inference that there was no application of the mind by the detaining authority to the vital question whether it was necessary to preventively detain the detenu. The facts of the present case are that the grounds of detention served on the appellant contain a very elaborate statement of facts quite clearly pointing to an application of the mind by the detaining authority. The appellant did not complain in the Writ Petition that the detaining authority had not applied its mind and in particular had not considered the question of the possibility of a prosecution. Nor are there any facts appearing from the record which can lead us to infer that the detaining authority did not apply its mind to relevant considerations. We do not	 therefore	 think that the order of detention is in any manner infirm. The appeal is accordingly dismissed. P.B.R. Appeal dismissed.

In Ashok Murlidhar vs State of Gujarat a Division Bench of the High Court thought that this Court in Hardhan Saha & Anr. vs The State of West Bengal & Ors.	 ; laid down that where a person was sought to be detained preventively the possibility of a prosecution being launched was an irrelevant consideration which need never be present to the mind of the detaining authority. Purporting to follow this decision another Division Bench of the High Court rejected the habeas corpus petition of the appellant who was in preventive detention under the provisions of . The Division Bench certified that a substantial question whether it is necessary for the detaining authority to consider whether a person should be prosecuted before an order of detention is made against him needed to be decided by this Court. In appeal to this Court it was contended on behalf of the appellant that it was axiomatic that the detaining authority must invariably consider the possibility of launching a prosecution before making an order of detention	 in the absence of which the order of detention must be held to be bad. Dismissing the appeal	 ^ HELD: 1. In Hardhan Saha 's case this Court did not say that the possibility of a prosecution being launched was an irrelevant consideration which need never be present to the mind of the detaining authority. All that was laid down in that case was that the mere circumstance that a detenu was liable to be prosecuted was not by itself a bar to the making of an order of preventive detention. It does not follow therefrom that failure to consider the possibility of a prosecution being launched cannot ever lead to the conclusion that the detaining authority never applied its mind and the order of detention was	 therefore	 bad. [57 F G] 2. The principles emerging from a review of the cases decided by this Court are that the ordinary criminal process is not to be circumvented or short circuited by ready resort to preventive detention	 but that the possibility of launching a criminal prosecution is not an absolute bar to an order of preventive detention. Nor is it correct to say that if such possibility is not present to the mind of the detaining authority the order of detention is necessarily bad. However	 the failure of the detaining authority to consider the possibility of launching a criminal prosecution may	 in the circumstances of a case	 lead to the conclusion that the detaining authority had not applied 55 its mind to the vital question whether it was necessary to make an order of preventive detention. Where an express allegation is made that the order of detention was issued in a mechanical fashion without keeping present to its mind the question whether it was necessary to make such an order when an ordinary criminal prosecution could well serve the purpose	 the detaining authority must satisfy the court that the question too was borne in mind before the order of detention was made. If the detaining authority fails to satisfy the court that the detaining authority so borne the question in mind the court would be justified in drawing the inference that there was no application of the mind of the detaining authority to the vital question whether it was necessary to preventively detain the detenu. [60 A D] In the instant case the grounds of detention served on the appellant contained a very elaborate statement of facts quite clearly pointing to an application of the mind by the detaining authority. The appellant did not complain in his petition that the detaining authority had not applied its mind and in particular had not considered the question of the possibility of a prosecution nor were there any facts appearing from the record which could lead to the conclusion that the detaining authority did not apply its mind to relevant considerations. The order of detention is not infirm in any manner.
