Summarize the following court judgment. ition Nos. 5931 and 5932 of 1980. (Under Article 32 of the Constitution.) N. M. Ghatate and section V. Deshpande for the Petitioners. M. K. Banerjee Addl. Genl.	 R. N. Poddar and Miss A. Subhashini for the Respondents. The Judgment of the Court was delivered by KOSHAL	 J. By this order we shall dispose of Criminal Writ Petitions Nos. 5931 and 5932 of 1980 in each of which the contention raised by the learned counsel for the petitioners is the same. In Criminal Writ Petition No. 5931 of 1980	 the petitioner is one Surjeet Singh while the other petition has been filed by a person named Kulwant Singh. 206 3. Each of the petitioners was detained on the 13th October	 1980 under the provisions of the National Security Ordinance which now stands replaced by the National Security Act. They were arrested on that date and on each of them a police officer served an order of detention along with the grounds on which it was based	 both the documents being in English. It is the case of the State and the same has not been controverted before us	 that the police officer effecting the service of the two documents explained to the concerned detenu in Hindi what their contents were. Dr. N. M. Ghatate	 learned counsel for the petitioners has challenged the detention of the two petitioners with the contention that English was not a language which either of them understood	 that this factor rendered it necessary for the grounds of detention to be served on them in Hindi which was their mother tongue and that the same having not been done	 there was in law no communication of such grounds to either of them. After hearing learned counsel for the parties	 we have no hesitation in holding that the challenge to the detention is well founded in view of the dicta of this Court in Harikisan vs The State of Madarashtra & Others	 Hadibandhu Das vs District Magistrate	 Cuttak & Anr.	 and Nainmal Partap Mal Shah vs Union of India and Others. In the first of these cases an order under the Preventive Detention Act (Central Act IV of 1950) was under challenge. The grounds of detention had been provided to the detenu in English and a request by him for a translation of the same was turned down. The High Court was of the opinion that so long as English continued to be the official language of the State	 the communication of the grounds of detention in that language was enough compliance with the requirements of the Constitution. This opinion did not find favour with Sinha	 C.J.	 who delivered the judgment of this Court and observed: If the detained person is conversant with the English language	 he will naturally be in a position to understand the gravamen of the charge against him and the facts and circumstances on which the order of detention is based. But to a 207 person who is not so conversant with the English language	 in order to satisfy the requirements of the Constitution	 the detenu must be given the grounds in a language which he can understand	 and in a script which he can read	 if he is a literate person. The Constitution has guaranteed freedom of movement throughout the territory of India and has laid down detailed rules as to arrest and detention. It has also	 by way of limitations upon the freedom of personal liberty	 recognised the right of the State to legislate for preventive detention	 subject to certain safeguards in favour of the detained person	 as laid down in clauses (4) and (5) of article 22. One of those safeguards is that the detained person has the right to be communicated the grounds on which the order of detention has been made against him	 in order that he may be able to make the representation against the order of detention. In our opinion	 in the circumstances of this case	 it has not been shown that the appellant had the opportunity	 which the law contemplates in his favour	 of making an effective representation against his detention. On this ground alone we declare his detention illegal	 and set aside the order of the High Court and the Order of Detention passed against him." In Hadibandhu 's case (supra) also an order under the Preventive Detention Act was impugned with the contention that the grounds of detention had not been supplied to the detenu in the language and script which he understood. The order was struck down by this Court for the reasons appearing in the following passage : "The grounds in support of the order served on the appellant ran into fourteen typed pages and referred to his activities over a period of thirteen years	 beside referring to a large number of court proceedings concerning him and other persons who were alleged to be his associates. Mere oral explanation of a complicated order of the nature made against the appellant without supplying him the translation in script and language which he understood would	 in our judgment amount to denial of the right of being communicated the grounds and of being afforded the opportunity of making a representation against the order. " 208 In Nainmal 's case	 Fazal Ali	 J.	 who followed Hadibandhu 's case	 held that the communication of the grounds of detention in a language understood by the detenu was an essential requirement for the validity of a detention order which	 in the absence of such requirement being fulfilled	 would be repugnant to the provisions of article 22(5) of the Constitution and would thus stand vitiated. And that is a view which has been consistently held by this Court. The facts with which we are here concerned	 in so far as they are relevant to the decision of the point canvassed before us	 are on all fours with those of the three cases cited above. As already pointed out	 the grounds of detention were supplied to the two petitioners in the English language a language with which they were not conversant. The service of the grounds on them in that manner could not be considered under the circumstances to be effective communication to them thereof so as to afford to them a real opportunity of making a representation against the order of detention. It is true	 as pointed out by the learned Additional Solicitor General	 that in Hadibandhu 's case (supra) the grounds of detention covered numerous pages and related to a long period of time and	 according to this Court	 contained "a complicated order". The complicated nature or the length of the document	 however	 was only mentioned incidentally by this Court and was not meant to be a sine qua non for the fulfilment of the requirement that the grounds must be supplied to the detenu in a language which he understood before the service on him of such grounds could be considered a communication thereof to him for the purposes of the Preventive Detention Act. In the result both the petitions succeed and are accepted. The detention of each of the petitioners is held to be repugnant to the provisions of article 22(5) of the Constitution and is struck down on that account. Both of them are directed to be set at liberty forthwith	 in so far as these petitions are concerned. V.D.K. Petitions allowed.

Allowing the petitions	 the Court ^ HELD: The supply to the detenus of the grounds of detention in the English language with which they were not conversant could not be considered to be effective communication to them so as to afford to them a real opportunity of making a representation against the order of detention. Their detention is repugnant to the provisions of Article 22 (5) of the Constitution. The complicated nature or the length of the document	 is not a sine qua non for the fulfilment of the requirement that the grounds must be supplied to the detenu in a language which he understood before the service on him of such grounds could be considered a communication thereof to him.
