Summarize the following court judgment. Civil Appeal No. 146 of 1981. From the Judgment and Order dated 10.5.1979 of the Allahabad High Court in S.A. No. 512 of 1975. M.K. Ramamurthi	 Syed Ali Ahmad	 Mrs. Jayashree Ahmad	 Syed Tanweer Ahmad and Mohan Pandey for the Appellant. V.C. Mahajan	 Hemant Sharma and C.V. Subba Rao for the Respondent. 1104 The Judgment of the Court was delivered by SINGH	 J. The short question which arises in this appeal is whether the disciplinary proceedings taken against the appellant resulting in his dismissal are null and void as the Enquiry Officer failed to comply with the principles of natural justice in holding the enquiry. The question relating to the non compliance of principles of natural justice is founded on the grievance that a copy of paper No. 5 although mentioned in the memo of charges was not supplied to the appellant	 and that he was not permitted to inspect the same. A learned single Judge of the High Court has answered the question against the appellant. Hence this appeal. The appellant was posted as fireman at Moghulsarai in Northern Railway in May	 1964. On 28th May 1964 coal lying at Pusauli Station was fraudulently removed by some person giving out his name as Shambhu Tiwari. A criminal case was registered	 but on account of absence of reliable evidence	 a final report was submitted. It appears that during the preliminary enquiry held by the Department it was found that Chandrama Tewari	 the appellant had removed the coal lying at Pusauli Station posing himself as Shambhu Tiwari	 a coal contractor. On completion of the preliminary enquiry a charge sheet was issued to the appellant on 6.2.1967. The appellant filed reply to the charges denying the same. An Enquiry Officer was appointed before whom evidence was recorded and the appellant was afforded full opportunity of cross examining the witnesses. The Enquiry Officer submitted his report holding the appellant guilty of charges framed against him. The punishing authority accepted the enquiry report and issued orders on 27.6.1969 dismissing the appellant from the service. The appellant filed a civil suit in the Trial Court for a declaration that the punishment of dismissal awarded to him was illegal and unconstitutional mainly on the ground that the enquiry had been held in violation of the principles of natural justice and he was denied reasonable opportunity of defence. A number of other grounds were also raised in the suit which need not be adverted as the controversy now is confined to the question of violation of the principles of natural justice alone. The trial court decreed the appellant 's suit on 31.1.1974. The decree of the trial court was confirmed in appeal by the District Judge by his order dated 2.11.1974. On a second appeal being filed by the Union of India the High Court set aside the judgment and decree of the subordinate courts on the findings that the appellant had been afforded reasonable opportunity of defence and there was no violation of any principles of natural justice in the enquiry. 1105 Learned counsel for the appellant Shri M.K. Ramamurthy contended that the memo of charges issued to the appellant expressly mentioned that paper No. 5 was proposed to be relied by the Department against the appellant but in spite of demand being made by the appellant a copy of that document was not supplied to him nor was he permitted to inspect the same. In the absence of that document the appellant was handicapped in cross examining Shri A.C. Das	 Dy. S.P.	 S.P.E. He further urged that failure to supply the copy of paper No. 5 was in violation of the principles of natural justice rendering the proceedings	 resulting in the order of dismissal as void. He placed reliance on decisions of this Court in State of Madhya Pradesh vs Chintaman	 AIR 1961 SC 1623; Trilokinath vs Union of India & Ors.	 ; The State of Assam & Anr. vs Mahendra Kumar Das & Ors.	 ; ; State of Punjab vs Bhagat Ram	 ; ; State of Uttar Pradesh vs Mohd. Sharif; AIR 1982 SC 937 and Kashinath Dikshita vs Union of India & Ors. 	 We have given our anxious consideration to the submissions made on behalf of the appellant and we have further considered the aforesaid authorities referred to by the learned counsel for the appellant but we do not find any merit in the appellant 's submissions to justify interference with the High Court 's judgment. Article 311 of the Constitution requires that reasonable opportunity of defence must be afforded to a government servant before he is awarded major punishment of dismissal. It further contemplates that disciplinary enquiry must be held in accordance with the Rules in a just and fair manner. The procedure at the enquiry must be consistent with the principles of natural justice. Principles of natural justice require that the copy of the document if any relied upon against the party charged should be given to him and he should be afforded opportunity to cross examine the witnesses and to produce his own witnesses in his defence. If findings are recorded against the government servant placing reliance on a document which may not have been disclosed to him or the copy whereof may not have been supplied to him during the enquiry when demanded would contravene principles of natural justice rendering the enquiry	 and the consequential order of punishment illegal and void. These principles are well settled by a catena of decisions of this Court. We need not refer to them. However	 it is not necessary that each and every document must be supplied to the delinquent government servant facing the charges instead only material and relevant documents are necessary to be supplied to him. If a document even though mentioned in the memo of charges is not relevant to the charges or if it is not referred to or relied upon by the enquiry officer or the punishing 1106 authority in holding the charges proved against the government servant	 no exception can be taken to the validity of the proceedings or the order. If the document is not used against the party charged the ground of violation of principles of natural justice cannot successfully be raised. The violation of principles of natural justice arises only when a document	 copy of which may not have been supplied to the party charged when demanded is used in recording finding of guilt against him. On a careful consideration of the authorities cited on behalf of the appellant we find that the obligation to supply copies of documents is confined only to material and relevant documents and the enquiry would be vitiated only if the non supply of material and relevant documents when demanded may have caused prejudice to the delinquent officer. In State of Madhya Pradesh vs Chintaman	 the respondent who was a police officer was dismissed from service on certain charges. The High Court of Madhya Pradesh quashed the order of dismissal on the finding that the enquiry was held in violation of the principles of natural justice in as much as the statement of witnesses recorded in the preliminary enquiry were not supplied to the concerned officer as a result of which he could not effectively cross examine the witnesses produced before the enquiry officer. This Court while upholding the view taken by the High Court	 observed that the departmental enquiries should observe rules of natural justice. The Court referred to the observations of Venkatarama Aiyar	 J. in Union of India vs T.R. Verma	 [1958] SCR 499 "stating it broadly and without intending it to be exhaustive it may be observed that rules of natural justice require that a party should have the opportunity of adducing all relevant evidence on which he relies	 that the evidence of the opponent should be taken in his presence	 and that he should be given the opportunity of cross examining the witnesses examined by that party	 and that no material should be relied on against him without his being given an opportunity of explaining them". Relying on the aforesaid observations the Court held that right to cross examine witnesses who give evidence against a delinquent officer is a very valuable right and if effective exercise of that right is prevented by the enquiry officer by not giving to officer relevant document to which he is entitled	 the enquiry cannot be said to have been held in accordance with the principles of natural justice. In Triloki Nath vs Union of India	 it was held that if a public servant facing enquiry was not supplied copies of documents it would amount to denial of reasonable opportunity. In that case the statement of witnesses recorded during the investigation of the criminal case registered against the delinquent officer prior to the 1107 departmental proceedings had not been supplied to him	 as a result of which the delinquent officer was prejudiced in his defence at the enquiry. In State of Assam and Anr. vs Mahendra Kumar Das & ors. J dismissal of a police sub inspector in pursuance of a disciplinary enquiry held against him had been set aside by the High Court on the ground that the enquiry officer had during the course of the enquiry consulted the Superintendent of Police	 Anti Corruption Branch and had taken into consideration certain material gathered from the AntiCorruption Branch	 without making the said material available to the sub inspector. On appeal by the State of Assam this Court held that it was improper for an enquiry officer during the conduct of an enquiry to collect any material from outside sources and in not making that material available to the delinquent officer. The Court observed that if the enquiry officer collects material behind the back of the delinquent officer and such material is relied upon by the enquiry officer without being disclosed to the delinquent officer	 the enquiry proceedings would be vitiated. After making these observations this Court recorded a finding that the enquiry officer had not taken into consideration the material contained in the records of Anti Corruption Branch	 and therefore failure to supply the material of the AntiCorruption Branch to the delinquent officer was of no consequence and it could not vitiate the enquiry. The Court set aside the order of the High Court on the finding that there had been no violation of principles of natural justice. In State of Punjab vs Bhagat Ram	 copies of statement of witnesses recorded during investigation and produced at the disciplinary enquiry in support of the charges framed against the delinquent officer were not supplied	 instead a synopsis of the statements had been supplied to him. This Court upheld the order of the High Court on the finding that it was unjust and unfair to deny the government servant copies of statement of witnesses recorded during investigation and produced in support of the charges levelled against the government servant. In the absence of the copies of the statement of witnesses the government servant could not have opportunity of effective and useful cross examine of the witnesses produced during the disciplinary enquiry. The Court observed that synopsis of statement did not satisfy the requirement of giving the government servant a reasonable opportunity. Same view was taken by this Court in State of Uttar Pradesh vs Mohd. Sharif	 as in that case also copies of the statement of witnesses recorded at the preliminary enquiry were not furnished to 1108 the delinquent government officer	 as a result of which the delinquent officer could not effectively cross examine the witnesses before the enquiry officer. In Kashinath Dikshita vs Union of India & ors.	 this Court set aside the order of dismissal of a police officer on the finding that during the departmental proceedings the officer concerned was not supplied the copies of statements made by the witnesses at a pre enquiry stage and also the copies of the documents on which reliance was placed in support of the charges	 in spite of specific request being made by the officer. The Court held that the order of dismissal was violative of Article 311 (2) in as much as the officer had been denied reasonable opportunity of defending himself. While setting aside the order of dismissal the Court observed that whether or not refusal to supply copies of documents or statements has resulted in prejudice to an officer facing the departmental enquiry depends on the facts of each case. After making this observation the Court examined the circumstances of that case and concluded that since 38 witnesses were examined against the officer and a large number of documents were relied upon against him and the disciplinary authority should have supplied the copies of the statement of witnesses recorded during the preliminary enquiry as we as the copies of the documents. Wherein agreement with the view taken in this decision It is now well settled that if copies of relevant and material documents including the statement of witnesses recorded in the preliminary enquiry or during investigation are not supplied to the delinquent officer facing the enquiry and if such documents are relied in holding the charges proved against the officer	 the enquiry would be vitiated for the violation of principles of natural justice. Similarly	 if the statement of witnesses recorded during the investigation of a criminal case or in the preliminary enquiry is not supplied to the delinquent officer	 as that would amount to denial of opportunity of effective cross examination. It is difficult to comprehend exhaustively the facts and circumstances which may lead to violation of principles of natural justice or denial of reasonable opportunity of defence. This question must be determined on the facts and circumstances of each case. While considering this question it has to be borne in mind that a delinquent officer is entitled to have copies of material and relevant documents only which may include the copy of statement of witnesses recorded during the investigation or preliminary enquiry or the copy of any other document which may have been relied in support of the charges. If a document has no bearing on the charges or if it is not relied by the 1109 enquiry officer to support the charges	 or if such document or material was not necessary for the cross examination of witnesses during the enquiry	 the officer cannot insist upon the supply of copies of such documents	 as the absence of copy of such document will not prejudice the delinquent officer. The decision of the question whether a document is material or not will depend upon the facts and circumstances of each case. In the instant case there is no denying the fact that a copy of paper No. 5 as mentioned in the charge sheet was not supplied to the appellant and he was not permitted to inspect the same. It appears that paper No. 5 was the report submitted by the Special Police Establishment in respect of the criminal case of theft of coal	 in which final report had been submitted. After submission of final report in the criminal case disciplinary enquiry was initiated against the appellant. Paper No. 5 (the report) was	 however	 not considered or relied by the enquiry officer in recording findings against the appellant. We have perused the copy of the report of the enquiry officer furnished to the Court by the appellant but we do not find any reference to paper No. 5 therein. The enquiry officer has not either referred to nor relied upon that report in recording findings on the charges framed against the appellant. In this view the report (paper No. 5) was not a material or relevant document and denial of copy of that document could not and did not prejudice the appellant and there was no violation of principles of natural justice. The appellant 's grievance that in the absence of report he could not effectively cross examine Shri A.C. Das	 Dy. S.P. Of Special Police Establishment	 the investigating officer	 is not sustainable. A copy of the statement as recorded by the enquiry officer has been placed before us by the appellant on a perusal of the same we find that Shri A.C. Das	 was cross examined at length in detail. His examination in chief is confined to one page while his cross examination runs into six full scape typed pages. The appellant has failed to point out as to how he was prejudiced. In our opinion the appellant was not handicapped in cross examining Shri A.C. Das	 his grievance that he was not afforded reasonable opportunity of defence is without any merit. In view of the above discussion we hold that the High Court was right	 in holding that the enquiry was fair and the principles of natural justice had not been violated. The appeal fails and is accordingly dismissed. There will be no order to costs. S.L. Appeal dismissed.

% Coal lying at the Pusauli Railway Station was fraudulently removed by some person	 giving out his name as Shambhu Tiwari	 a coal contractor. A criminal case was registered	 but on account of absence of reliable evidence final report was submitted. During the preliminary enquiry held by the Department	 it was found that Chandrama Tewari	 the appellant	 who was posted as a fireman at Moghulsarai in the Northern Railway	 had removed the coal posing himself as Shambhu Tiwari. A charge sheet was issued to the appellant. An Enquiry Officer was appointed before whom evidence was recorded. The appellant was afforded full opportunity of cross examining the witnesses. The Enquiry Officer held the appellant guilty of the charges framed against him. The punishing authority accepted the report of the enquiry officer and passed orders	 dismissing the appellant from service. The appellant filed a civil suit for a declaration that the punishment of dismissal was illegal and unconstitutional mainly on the ground that the enquiry had been held in violation of the principles of natural justice and he was denied reasonable opportunity of defence	 inasmuch as a copy of paper No. 5	 mentioned in the Memo of charges	 had not been supplied to him. The trial court decreed the suit. The decree of the trial court was confirmed in appeal by the District Judge. On a second appeal by the Union of India	 the High Court set aside the decisions of the subordinate courts	 holding that the appellant had been afforded reasonable opportunity of defence and there had been no violation of the principles of natural justice in the enquiry. The appellant appealed to this Court against the order of the High Court. Dismissing the appeal	 the court	 1103 ^ HELD: It is not necessary that each and every document must be supplied to the delinquent government servant facing charges; instead	 only material and relevant documents are necessary to be supplied to him. If a document even though mentioned in the Memo of charges is not relevant to the charges or if it is not referred to or relied upon by the enquiry officer or the punishing authority in holding the charges proved against the government servant	 no exception can be taken to the validity of the proceedings or the order passed on the ground of non supply of the copy of the order. If a document is not used against the party charged	 the ground of violation of principles of natural justice cannot be successfully raised. Violation of the principles of natural justice arises only when a document	 a copy of which may not have been supplied to the party charged	 is used in recording findings of guilt against him. [1105G H; 1106A B] Copy of paper No. 5	 mentioned in the charge sheet	 was not supplied to the appellant and he was not permitted to inspect the same. But that document was not considered	 or relied upon by the enquiry officer in recording the findings against the appellant. Therefore	 the paper No. 5 was not a material or relevant document	 and denial of a copy of that document did not prejudice the appellant and there was no violation of the principles of natural justice involved in the case. The enquiry was fair.
