Summarize the following court judgment. : Criminal Appeal No. 502 of 1976. (Appeal by Special Leave from the Judgment and Order dated 16 9 1975 of the Delhi High Court in Criminal Revision No. 139 of 1975). A.K. Gupta	 for the appellants. G. Das	 and R.N. Sachthey	 for the respondent. The Judgment of the Court was delivered by CHANDRACHUD	 J. The appellants who are Railway employ ees	 were convicted by the learned Metropolitan Magistrate	 Delhi under rules 118 and 119 of the Defence of India Rules	 1971 and were sentenced to six months ' rigorous imprison ment. The order of conviction was upheld in appeal by the learned Additional Sessions Judge and in revision by the Delhi High Court with the difference that whereas the former upheld the sentence too	 the latter has reduced it to the period already undergone. In this appeal by special leave the Iegality of conviction is questioned by the appel lants. The case of the prosecution is that the appellants are leaders of the Northern. Railwaymen 's Union and that on May 5	 1974 they 993 held a meeting in Tughlakabad Railway Yard inciting railway workers to go on strike from May 8. This is alleged to be in breach of the order passed by the Government of India under rule 118(1) of the Defence of India Rules	 1971. That rules reads thus: "118. Avoidance of strikes and lock outs. (1) If in the opinion of the Central Government or the State Government it is necessary or expedient so to. do for securing the defence of India and civil defence	 the public safety	 the maintenance of public order or the efficient conduct of military Opera tions	 or for maintaining supplies and services essential to the life of the communi ty	 nothwithstanding anything contained in any other provisions of these rules	 the Central Government may	 by general or special order	 applying generally or to any specific area and to .any undertaking or class of undertakings	 make provision (a) for prohibiting	 subject to the provisions of the order	 a strike or lock out in connection with any industrial dispute; (b) for requiring employers	 workmen	 or both	 to observe for such period as may be	 specified in the order such terms and conditions of employment as may be determined in accordance with the order: Provided that no order made under clause (b) shall require any employer to observe terms and conditions of employment less favourable to. the workmen than those which were applicable to them at any time within three months preceding the date of the order. " By sub rule (2)	 if any person contravenes any order made under sub rule (1) he shall be punishable with imprison ment for a term which may extend to three 'years or with fine or with both. The order issued under rule 118(1)(b) by the Government of India in its Ministry of Labour on November 26	 1973 recites that in the opinion of the Central Government it was necessary and expedient for maintaining supplies and serv ices essential to the life of the community to prevent strikes in the Railway Services 'and that therefore "the Central Government hereby prohibits a strike in connection with any industrial dispute/disputes in the said Railway Services in India for a period of six months w.e.f. the 26th November	 1973. " In support of its case the prosecution examined three witnesses called S.D. Sharing	 Dilbagh Rai and jasbir Singh. Sharma 's evidence is in the nature of hearsay and indeed he admits in so many words that his knowledge regarding the incitement given by the appellants to the Railway workers to go on strike was derived solely from information received by him. The witness admits that he had no personal knowledge that the appellants had held any meeting nor had 994 he heard their speeches. The second witness Dilbagh Rai was in charge of the Police Post at Tughlakabad Railway Station and was entrusted with the investigation of the case. In the nature of things he too has no personal knowledge of what the appellants did or said. Jasbir Singh who was in charge of the Diesel Shed at Tughlakabad is in the circumstances the only witness whose evidence could	 if at all	 help the prosecution to establish the charge that the appellants had contravened the order issued by the Government of India under r. 118(1)(a) of the Defence of India Rules	 1971. But even that evidence	 in our opinion	 is inadequate for proving the charge levelled against the appellants. Jasbir Singh claims to have attend ed a meeting addressed by the appellants but he has not stated as to what exactly the appellants said in the meet ing. He has given his own gist or summary of what the appellants meant to convey to the audience stating that they incited the workers to go on strike and threatened them with dire consequences if they did not respond to the call. Such a broad	 resume is not safe to rely upon for holding the charge proved. In view of the total absence of evidence showing what the appellants in fact said in the meeting	 the summary coined by Jasbir Singh of the happenings in the meeting cannot form the basis of conviction. What is chargeable as contravening the prohibition imposed under the order issued by the Government of India under r. 118(1)(a) is in the circumstances of this case the words used by the speakers and not the gist of the speeches made by a member of the audience. A summary of a speech may broadly and generally not be inaccurate and yet it may not faithfully reflect what the speaker actually said and in what context. Therefore	 we would prefer not to rely on the gist given by the witness without knowing the data on the basis of which the gist was given. The charge must therefore fail. One of the points urged before us is whether the courts below were justified in taking judicial notice of the fact that on the date when the appellants delivered their speech es a railway strike was imminent and that such a strike was in fact launched on May 8	 1974. Section 56 of the Evidence Act provides that no fact of which the Court will take judicial notice need be proved. Section 57 enu merates facts of which the Court "shall" take judicial notice and states that on all matters of public history	 literature	 science or art the 'Court may resort for its aid to appropriate books or documents of reference. The list of facts mentioned in section 57 of which the Court can take judicial notice is not exhaustive. and indeed the purpose of the section is to> provide that the .Court shall take judicial notice of certain facts rather than exhaust the category of facts of which the Court may in appropriate cases take judicial notice. Recognition of facts without formal proof is a. matter of expediency and no one has ever questioned the need and wisdom of accepting the existence of matters which are unquestionably within public knowl edge. (see Taylor 11th edn. pp 3 12; Wigmore sec 2571 foot note; Stephen 's Digest	 notes to Art	 58; Whitley Stokes ' Anglo Indian Codes Vol. II p. 887). Shutting the judicial eye to the 995 existence of such facts and matters is in a sense an insult to commonsense and would tend to reduce the judicial process to a meaningless and wasteful ritual. No Court therefore insists on formal proof	 by evidence	 of notorious facts of history	 past or present. The date of poll	 the passing away of a man of eminence and events that have rocked the nation need no proof and are judicially no ticed. Judicial notice	 in such matters	 takes the place of proof and is of equal force. In fact	 as a means of establishing notorious and widely known facts it is supe rior to formal means of proof. Accordingly	 the Courts below were justified in assuming	 without formal evidence	 that the Railway strike was imminent on May 5	 1974 and that a strike intended to paralyse the civic life of the Nation was undertaken by a section of workers on May 8	 1974. But the matter does not rest there. Rule 118(1)(a) empowers the Government to issue an order prohibiting a strike "in connection with any industrial dispute". The Order issued by the Government on November 26	 1973 recites	 as required by the Rule	 that the Central Government prohib its a strike "in connection with any industrial dispute" in the Railway Services in India for a period of six months. Rule 118 (2) prescribes punishment for a person who con travenes any order made under the Rule. We have no doubt that the Government possesses the power to issue an appro priate order under Rule 118 (1) even if there is no existing industrial dispute because the power can be exercised prophylactically for preventing a strike in connection with an imminent industrial dispute. But the prosecution must establish	 in order that the conduct charged as penal may fall within the mischief of the Order	 that the strike in regard to which the incitement was given was in connection with an industrial dispute. Unless that is established	 there can be no contravention of the order issued by the Government	 because the contravention consists in doing what is prohibited by the order. And what is prohibited by the order is a strike in connection with an industrial dispute. Thus the prosecution has to establish not only that a strike was imminent or had actually taken place	 of which judicial notice may be taken	 but further that the strike was in connection with an industrial dispute	 which is a matter of evidence. Rule 118(1)(a) limits the power of the Government to issue an appropriate order	 general or special	 for prohibiting inter alia a strike in connection with any industrial dispute. Since the rule does riot empower the Government to issue an order prohibiting strikes generally	 whether they bear any connection with an industrial dispute or not	 there can be no contravention of the order unless it is established by evidence that the strike was in connection with an industrial dispute. The prosecution did not lead any evidence to prove this impor tant ingredient of the offence and the generalisation made ' by the witnesses in their evidence is wholly inadequate for accepting that the appellants gave incitement to a strike in connection with any industrial dispute. It is urged by the learned counsel appearing for the Delhi Administration	 who are respondents to the appeal	 that what is contemplated by rule 118(1)(a) itself is a strike in connection with 996 an industrial dispute and therefore it is not necessary for the prosecution to establish that the strike was in connec tion with any industrial dispute. There is no warrant for this submission and nothing contained in sub rule (3) of rule 118 which defines the expressions "industrial dispute" and "strike" lends support to the counsel 's submission. It is well known that strikes are sometimes undertaken for purposes unconnected with an industrial dispute	 as for example when the workers demand a closure of the establish ment on the demise Of a person of national importance. In fact	 strikes are not unoften launched for reasons which do not reasonably bear any connection with an industrial dispute. An argument was advanced before us on behalf of the appellants that the conduct attributed to the appellants does not fall within the mischief of the order because inciting other workers to go on strike is outside the defi nition of the word "strike" contained in rule 118(3)(b) of the Defence of India Rules	 1971. It i	s unnecessary to consider this question in view of our finding that the evidence led by the prosecution is insufficient to 'estab lish the charge levelled against the appellants. We would however like to point out that the appropriate provision of the Defence of India Rules under which an incitement to strike as in the instant case may be punished is rule 36(6)(j) read with rule 43(1)(a). The former defines a "prejudicial act" to include instigation or incitement for cessation or slowing down of work by a body of persons employed in any place of employment in which 100 persons or moro are normally employed	 in furtherance of any strike which is prohibited under rule 118 or is illegal under any law for the time being in force. The latter provides that no person shall without lawful authority or excuse do any prejudicial act. By rule 43 (5) a person who contravenes any of the provisions of rule 43 is punishable with impris onment which may extend to 5 years or with fine or with both. In the result we allow the appeal	 set aside the order of conviction and sentence and acquit the appellants. S.R. Appeal allowed.

In respect of an alleged speech made	 on May 5	 1974	 at a meeting held in Tughlakabad Railway Station Yard inciting workers to go on strike from May 8	 1974	 the appellants who were leaders of the Northern Railwaymen 's Union were convicted by the learned Metropolitan Magistrate under Rule 118 and 119 of the Defence of India Rules and sentenced to six months rigorous imprisonment. The order of conviction was upheld in appeal by the Sessions Court but in revision	 the Delhi High Court while upholding the conviction re duced the sentence to the period already undergone. In appeal by special leave to this Court	 the appellants contended (1) There was no legal evidence to warrant the conviction; (2) The courts below were not justified in taking judicial notice of the fact that on the date when the appellants delivered their speeches a railway strike was imminent and that such a strike. was	 in fact	 launched on May 8	 1974 and (3) The conduct attributed to the appellants does not fall within the mischief of the order because inciting other workers to go on strike is outside the defi nition of the word "strike" contained in rule 118(3)(b) of the Defence of India Rules	 1971. Allowing the appeal by special leave	 the court	 HELD: (1) The courts below were justified in assuming without formal evidence that the railway strike was immi nent on May 5. 1974 and that a strike intended to paralyse the civic life of the nation was undertaken by a section of workers On May 8	 1974. [995A B] (2) The purpose of section 57 of the Evidence Act is to provide that the court shall take judicial notice of certain facts rather than exhaust the category of facts of which the court may in appropriate cases take judicial notice. Recog nition of facts without formal proof is an act of expedien cy. Shutting the judicial eye to the existence of such facts and matters is in a sense an insult to commonsense and would tend to reduce the judicial process to a meaningless and wasteful ritual. No court insists on a formal proof by evidence of notorious facts of history past or present and events that have rocked the nation need no roof and are judicially noticed. judicial notice in such matters takes place of proof and is of equal force. [994F H	 995 A] (3) The Government possesses the power to issue an appropriate order under rule 118(1) prohibiting the strike "in connection with any industrial dispute" even if there is no existing industrial dispute because the owner can be exercised prophylactically by preventing a strike in connec tion with an imminent strike. [995C D] (4) In order to maintain a charge under rule 118(1) of the Defence of India Rules	 1971	 the prosecution has to establish not only that a strike was imminent or had actual ly taken place of which indicial notice may be taken but further that the strike was in connection with the industri al dispute which is a matter of evidence. [995E F] 992 (5) What is chargeable as contravening the prohibition must under the order issued by the Government of India under Rule 118(1)(a) is	 in the circumstances of this case	 the words used by the speakers and not the gist of the speeches made by a member of the audience. A summary of speech may broadly and generally not be inaccurate and it may ' not faithfully reflect what the speaker actually said and in what context. [994D E] (6) Rule 118(1)(a) limits the power of the Government to issue an appropriate order	 general or special	 for prohib iting inter alia	 a strike in connection with any industrial dispute. Since the rule does not empower the Government to issue an order prohibiting strikes generally	 whet.her it is in connection with the industrial dispute or not	 there can be no contravention of the order unless it is established by evidence that the strike was in connection with an industri al dispute. In the instant case	 the prosecution did not lead any evidence to prove this important ingredient of the offence and the generalisation made by the witnesses in their evidence is wholly inadequate for accepting that the appellants gave incitement to a strike in connection with any industrial dispute. [995F G] (7) The contention of the prosecution that what is contem plated by rule 118 (1)(a) itself is a strike in connection with an industrial dispute and	 therefore	 it is not neces sary for the prosecution to establish that the strike was in connection with any industrial dispute is neither warranted nor supported by anything contained in sub rule (3) of rule 118 which defines expressions "industrial dispute" and "strike". [995H	 996A B] [In view of the finding that the evi dence led by the prosecution is insufficient to establish the charge	 in the instant case	 the court thought it unnecessary to consider the question whether the conduct attributed to the appellants fall within the mischief of the order dated 26 11 1973	 since inciting other workers to go on strike may be outside the definition of the words "strike" contained in Rule 118(3)(b) of the Defence of India Rules	 1971. " The court	 however	 pointed out that the appropriate provision of the Defence of India Rules under which an incitement to strike as in the instant case may be punished in Rule 36(6) read with Rule 43(1)(a).]
