From the Judgment and Order dated 31 3 1986 of the Allahabad High Court in W.P. Nos. 1448 and 1405 of 1986. A.K. Gupta for the Petitioners in W.P. Nos. 300 and 301 of 1986. S.A. Syed and Shakil Ahmed for the Appellants in Crl. A. Nos. 374A and 411 of 1986. A.D. Singh	 Ms. Rachna Joshi and Dalveer Bhandari for the Respondents. The Judgment of the Court was delivered by PATHAK	 C.J. I. The petitioners Fazal Ghosi and Wahid in the two writ petitions before us and the appellants Ayaz Ahmad and Riaz Ahmad in the two Criminal Appeals are ag grieved by the orders of detention made respectively in respect of them under sub s.(2) of section 3 of the . The petitioners Fazal Ghosi and Wahid filed writ petitions in the High Court of Allahabad against the detention orders concerning them and those writ peti tions were dismissed. They have now filed the present peti tions under Article 32 of the Constitution. The appellants Ayaz Ahmad and Riaz Ahmad filed writ petitions in the High Court of Allahabad against the detention orders concerning them	 and those writ petitions having been dismissed they have appealed here by special leave. All the four cases have been heard together. It is agreed between the parties that although separate orders of detention were made under sub section (2) of section 3 of the against the various petitioners and appellants the grounds raised in this court against their detention orders are identical. It appears that consequent upon the opening of the Ram Janam Bhumi temple at Ayodhya	 Faizabad	 there was consider able agitation 473 among the Muslim community. According to the State Govern ment	 several members of the community were returning from the mosque after their afternoon prayers	 and at Bholanath Ka Kuan	 Abdul Aziz Road	 Lucknow they were addressed by Fazal Ghosi and his son Wahid in language inciting them to beat the police and the Police Armed Constabulary. At anoth er place	 Sarkata Nala	 a large number of the Muslim commu nity are said to have been similarly addressed by the appel lants	 Ayaz Ahmd and Riaz Ahmad. It is alleged that in consequence the crowd commenced pelting stones and dis charged fire arms on the Government officials and the police personnel assembled there as a result of which they received injuries. The petitioners and the appellants were arrested along with other persons	 and a First Information Report was lodged in respect of each of them for offences under sec tions 147/148/149/307 and 332 of the Indian Penal Code. The petitioners and the appellants applied for grant of bail	 and while the bail applications were pending the District Magistrate	 Lucknow	 purporting to act under sub section (3) of section 3 of the 	 served a detention order on February 20	 1986 on each of the four detenus. This was followed on February 21	 1986 by service of the grounds of detention. Learned counsel for the detenus challenges the detention orders on several grounds. In our opinion	 it is not neces sary to consider all the points raised because it appears to us that the cases can be disposed of on a short ground. The contention on behalf of the detenus is that there was no material before the District Magistrate on the basis of which he could form the opinion that the detenus would act in future in a manner prejudicial to the maintenance of public order. It is pointed out that the provides for preventive detention. and preventive deten tion is intended where it is apprehended that the person may act prejudicially to one or more of the considerations specified in the statute. There is no doubt that preventive detention is not intended as a punitive measure	 as a cur tailment of liberty by way of punishment for an offence already committed. Section 3 of the Act clearly indicates that the power to detain thereunder can be exercised only with a view to preventing a person from acting in a manner which may prejudice any of the considerations set forth in the section. In the present case	 we are unable to discover any material to show that the detenus would act in the future to the prejudice of the maintenance of public order. Even if it is accepted that they did address the assembly of persons and incited them to lawlessness there is no material to warrant the inference that they would repeat the miscon duct or do anything else which would be prejudicial to the maintenance of public order. The District Magistrate	 it is true	 has stated that the detention 474 of the detenus was effected because he was satisfied that it was necessary to prevent them from acting prejudicially to the maintenance of public order	 but there is no reference to any material in support of that satisfaction. We are aware that the satisfaction of the District Magistrate is subjective in nature	 but even subjective satisfaction must be based upon some pertinent material. We are concerned here not with the sufficiency of that material but with the existence of any relevant material at all. In the circumstances. the detention orders in respect of the four detenus must be quashed. The writ petitions and the appeals are allowed	 the order of detention in respect of each detenu is quashed	 and the detenus are entitled to be set at liberty unless their detention is required in connection with other cases. N.P.V. Petitions and appeals allowed.

Consequent upon the opening of the Ram Janam Bhumi Temple at Ayodhya	 there was considerable agitation among the Muslim Community. The Petitioners and appellants were arrested for inciting the members of the community to in dulge in violence and charged for offences under sections 147/148/149/307/332 of the Indian Penal Code. While their bail applications were pending; the District Magistrate	 purporting to act under sub.s. (3) of section 3 of the 	 served detention orders on them. Writ Petitions challenging the detention orders filed by the appellants were rejected by the High Court. The Petitioners and appellants contended that the deten tion orders were bad for the reason that there was no mate rial before the District Magistrate on the basis of which he could form the opinion that they would act in future in a manner prejudicial to maintenance of public order. Allowing the petitions and appeals	 this Court	 HELD: The power to detain under the Act can be exercised only with a view to preventing a person from acting in a manner which may prejudice any of the considerations set forth in Section 3 thereof. Preventive detention is not intended as a punitive measure	 as a curtailment of liberty by way of punishment for an offence already committed. No doubt the satisfaction of the District Magistrate making the detention order is subjective in nature	 but	 even subjec tive satisfaction	 must be based upon some pertinent materi al. [473F G; 474A B] In this case there is no material to show that the detenus would act 472 in the future to the prejudice of the maintenance of public order. Even if it is accepted that the detenus did address the assembly of persons and incited them to lawlessness	 there is no material to warrant the inference that they would repeat the misconduct or do anything else which would be prejudicial to the maintenance of public order.
