Summarize the following court judgment. minal Appeal No. 178 of 1957. 117 920 Appeal by special leave from the order dated May 28	 1956	 of the former Nagpur High Court in Criminal Revision No. 150 of 1956 arising out of the order dated February 2	 1956	 of Shri K. L. Pandey	 Special Magistrate at Nagpur in Criminal Case No. I of 1955. R. Patnaik	 for the appellant. section N. Bindra and R. H. Dhebar	 for the respondent. May 22. The Judgment of the Court was delivered by KAPUR J. This is an appeal against the judgment and order of the High Court of Nagpur confirming the decision of the Special Magistrate disallowing the application of the appellant to give evidence as a witness under section 342A of the Criminal Procedure Code. The Advocate General of Madhya Pradesh	 on January 13	 1953	 filed a complaint against the appellant and three others under section 282 of the Indian Companies Act and sections 465 and 477A of the Indian Penal Code. The proceedings commenced in 1954 before a Magistrate but on May 18	 1955	 they were transferred to a Special Magistrate who commenced the recording of evidence on July 4	 1955. On August 12	 1955	 the Criminal Procedure Code (Amendment) Act (26 of 1955) received the assent of the President and came into force on January 2	 1956. In this judgment it will be referred to as the Amending Act and the Code of Criminal Procedure as the Code. On January 14	 1956	 the appellant made an application to the Magistrate claiming the right to appear as a witness on his own behalf under section 342A of the amended Code "in disproof of the charges made against him ". His application was dismissed and so was his revision to the High Court of Nagpur which held: " While it must be conceded that the wording of clause (c) as also the other clauses of section 116 of the amending Act could have been put in simpler and more direct language	 its ingenuous circumlocution cannot be allowed to cloak. its true meaning or to permit the construction which the applicant seeks to 921 put upon it. The language used doe	 	 not justify hold ing that when the statute says " this Act it means only " some of the provisions of this Act Thus the High Court was of the opinion that the proceedings pending before the Special Magistrate would be according to the procedure laid down in the unamended Code and the appellant could not therefore appear as a witness under section 342A of the amended Code. According to the provisions of the unamedded Code an accused person could not appear as a witness in his defence although for the purpose of enabling him to explain circumstances appearing in the evidence against him the Court could put such questions as it considered necessary. Section 118 of the Evidence Act deals with persons who are competent to testify as witnesses but in view of section 342 of the unamended Code no accused person could appear as a witness and there fore section 118 was inapplicable to such persons. Article 20(3) of the Constitution provides that no person accused of an offence shall be compelled to be a witness against himself and section 342A was inserted into the Code by section 61 of the amending Act. It provides: S.342A " Any person accused of an offence before a Criminal Court shall be a competent witness for the defence and may give evidence on oath in disproof of the charges made against him or any person charged together with him at the same trial: Provided that (a) he shall not be called as a witness except on his own request in writing; or (b) his failure to give evidence shall not be made the subject of any comment by any of the parties or the Court to give rise to any presumption against him:self or any person charged together with him at the same trial." Thus the law was amended and the accused person has become a competent witness for the defence but he cannot be compelled to be a witness and cannot be called as a witness except at his own request in writing and his failure to give evidence cannot be 922 made the subject matter of comment by the parties or the Court. The question that arises for decision is whether to a pending prosecution the provisions of the amended Code have become applicable. There is no controversy on the general principles applicable to the case. No person has a vested right in any course of procedure. He has only the right of prosecution or defence in the manner prescribed for the time being by or for the Court in which the case is pending and if by an Act of Parliament the mode of procedure is altered he has no other right than to proceed according to the altered mode. See Maxwell on Interpretation of Statutes on p. 225; The Colonial Sugar Refining Co. Ltd. vs Irving (1). In other words a change in the law of procedure operates retrospectively and unlike the law relating to vested right is not only prospective. The amending Act contains provisions in regard to the procedure to be applied to pending cases in section 116 which is as follows: S.116 " Notwithstanding that all or any of the provisions of this Act have come into force in any State (a)the provisions of section 14 or section 30 or section 145 or section 146 of the principal Act as amended by this Act shall not apply to or affect	 any trial or other proceeding which	 on the date of such commencement	 is pending before any Magistrate and every such trial or other proceeding shall be continued and disposed of as if this Act had not been passed ; (b)the provisions of section 406 or section 408 or section 409 of the principal Act as amended by this Act shall not apply to	 or affect	 any appeal which	 on the date of such commencement	 is pending before the District Magistrate or any Magistrate of the First class empowered by the State Government to hear such appeal	 and every such appeal shall	 notwithstanding the repeal of the first proviso to section 406 or of section 407 of the principal Act	 be heard and disposed of as if this Act had not been passed; (i)(1905) A.C. 369	372. 923 (c)the provisions of clause (w) of section 4 or section 207A or section 251A or section 260 of the principal Act as amended by this Act shall not apply to, or affect, any inquiry or trial before a Magistrate in which the Magistrate has begun to record evidence prior to the date of such commencement and which is pending on that date, and every such inquiry or trial shall be continued and disposed of as if this Act had not been passed; (d)the provisions of Chapter XXIII of the principal Act as amended by this Act shall not apply to, or affect, any trial before a Court of Sessions either by jury or with the aid of assessors in which the Court of Sessions has begun to record evidence prior to the date of such commencement and which is pending on that date, and every such trial shall be continued and disposed of as if this Act had not been passed; but save as aforesaid, the provisions of this Act and the amendments made thereby shall apply to all pro ceedings instituted after the commencement of this Act and also to all proceedings pending in any Criminal Court on the date of such commencement.  It was contended on behalf of the respondent that the following words in clause (c) of section 116 of the amending Act " and every such enquiry or trial shall be continued and disposed of as if this Act had not been passed " mean that no provision of the Act would be applicable to pending trials and particular stress was laid on the words " as if this Act had not been passed". If that is the interpretation to be put then it would be in conflict with the last portion of the section i. e. " Save as aforesaid the provisions of this Act and the amendments made thereby shall apply to all proceedings instituted after the commencement of this Act and also to all proceedings pending in any Criminal Court on the date of such commencement. " The language used in this portion of the section in regard to the proceedings which are instituted after the commencement of the amended Code is identical with that dealing with proceedings pending in a Criminal Court on the date of its commencement. Therefore if this Act applies to all proceedings which commenced 924 after the Act came into force they would equally apply to proceedings which had already commenced except those provisions which have been expressly excluded. If the whole section is construed in the manner contended for by the respondent then there will be a conflict between the words used in the various clauses and words used in the main section 116 and it is one of the principles of interpretation that the words should be construed in such a manner as to avoid a conflict. Thus construed the words of cl. (c) and the words of the rest of the section 116 would mean this that the pro visions of sections 4 (w)	 207A	 251A or 260 of the Code as amended shall not apply or affect any enquiry or trial before a Magistrate where the recording of evidence has started prior to the date of the commencement of the amending Act and every such enquiry should be continued and disposed of as if these sections had not been enacted. Except as to this and except as to the provisions mentioned in sub cls. (a)	 (b) and (d) the other provisions of the amended Code would be applicable to such proceedings which is also in accordance with the general principles applicable to amendments in procedural law. By section 34 of the amending Act	 section 251 of the Code was substituted by two sections i. e. 251 and 251A. Section 251 lays down the procedure in warrant cases. It provides: section 251 " In the trial of warrant cases by Magi. strates	the Magistrate shall	 (a) in any case instituted on a police report	 follow the procedure specified in section 215A; and (b) in any other case	 follow the procedure specified in the other provisions of this Chapter. " Sub clause (a) deals with cases instituted on a police report and sub cl. (b) with other cases. To the former section 251A is applicable and to other cases procedure specified in other provisions in Chapter 21 is made applicable. Section 342A is in Chapter 24 and there is nothing in the amending Act or the amended Code which makes the provision of section 342A inapplicable to criminal proceeding 	 which are pending before a Magistrate and in which the recording of evidence has commenced. 925 In our opinion on the plain construction of the words used in section 116 of the amending Act	 section 342A available to the appellant. The High Court	 it appears	 was misled into construing the words in clause (c) of section 116 i. e. "as if this Act had not been passed". The High Court was therefore in error and the appellant is entitled	 in our view	 as a competent witness for the defence to testify in disproof of the charges made against him or any other person charged together with him at the same trial. We would	 therefore.	 allow this appeal	 set aside the order of the courts below and hold that the application made by the appellant to appear as a witness was well founded and should have been allowed. Appeal allowed.

A complaint was filed against the appellant on January 13	1953	 and the Special Magistrate trying him commenced the recording of evidence on July 4	 955. During the trial the Criminal Procedure Code (Amendment) Act (26 of 955) came into force on January 2	 1956	 which introduced section 342 A in the Code of Criminal Procedure. The appellant made an application to the Magistrate claiming the right to appear as a witness on his own behalf under section 342 A in disproof of the charges made against him. The Magistrate rejected the application on the ground that section 342 A could not be applied to pending proceedings which would be according to the procedure laid down in the unamended Code: Held	 that on a plain construction of section ii6 of the amending Act which provided for procedure to be followed in pending cases section 342 A was clearly applicable in such cases. Under the general law also a change in procedure operates retrospectively.
