Summarize the following court judgment. iminal Appeal No. 8 of 1966. Appeal by special leave from the judgment and order dated April 29	 1965 of the Punjab High Court	 Circuit Bench at Delhi in Criminal Appeal No. 164 D of 1962. Bishan Narain	 K. K. Raizada and A. G. Ratnaparkhi	 for the appellant. Sardar Bahadur and Yougindra Khushalani	 for respondent No. 1. R. N. Sachthey	 for respondent No. 2. The Judgment of the Court was delivered by Ramaswami	 J. On August 29	 1960 Shri Sham Sundar Mathur	 Municipal Prosecutor of the Delhi Municipal Corporation filed a complaint in the court of Magistrate First Class against the respondent	 Jagdishlal under section 7 read with section 16 of the (37 of 1954). In the said complain Shri Sham Sundar Mathur said that lie was competent to file the complaint under section 20 of the aforesaid Act in accordance with a resolution passed by the Corporation in its meeting held on December 23	 1968. By his order dated April 30	 1962 the learned Magistrate acquitted the respondent. The Delhi Municipal Corporation made an application to the High Court asking for special leave under section 417 of the Code of Criminal Procedure to appeal against the order of acquittal. The application was ranted on September 3	 1962. When the appeal came up for hearing a preliminary objection was raised on of the respondent that the only person competent to file the appeal was the complainant	 Shri Sham Sundar Mathur. But the leave application was not filed by him and	 therefore	 the Municipal Corporation was not competent to prosecute the appeal. It was contended that only the complainant was competent to present an application for special leave under section 417(3) of the Code of Criminal Procedure. As the complainant in this case was Shri Sham Sundar Mathur the appeal could not be filed by the Delhi Municipal Corporation. The High Court upheld the preliminary objec tion of the respondent and dismissed the appeal by its order dated April 29	 1965. This appeal is brought by special leave on behalf of the Delhi Municipal Corporation against the judgment of the High Court dated April 29	 1965 in Cr. No. 163 D of 1962. Section 20 of the states : 581 " (1) No prosecution for an offence under this Act shall be instituted except by	 or with the written consent of	 the Central Government or the State Government or a local authority or a person authorised in this behalf	 by general or special order	 by the Central Government or the State Government or a local authority : Provided that a prosecution for an offence under this Act may be instituted by a purchaser referred to in section 12	 if he produces in court a copy of the report of the public analyst along with the complaint. Section 417	 sub sections (1)	 (2) and (3) of the Code of Criminal Procedure after its amendment by Act 26 of 1955 provide : " (1) Subject to the provisions of sub section (5)	 the State Government may	 in any case	 direct the Public Prosecutor to present an appeal to the High Court from an original or appellate order of acquittal passed by any Court other than a High Court. (2)If such an order of acquittal is passed in any case in which the offence has been investigated by the Delhi Special Police Establishment constituted under the (XXXV of 1946)	 the Central Government may also direct the Public Prosecutor to present an appeal to the High Court from the order of acquittal. (3)If such an order of acquittal is passed in any case instituted upon complaint and the High Court	 on an application made to it by the complainant in this behalf	 grants special leave to appeal from the order of acquittal	 the complainant may present such an appeal to the High Court. The principal question to be determined is whether the com plaint dated August 29	 1960 was instituted by the Delhi Municipal Corporation. It is argued on behalf of the respondent that the complaint petition was not made and signed by the person competent under the Delhi Municipal Corporation Act	 1957 to exercise powers of the	 Corporation in the matter of institution of legal proceedings. In our opinion there is substance in this contention. The only provision under the Delhi Municipal Corporation Act	 1965 which confers power to institute legal proceedings is section 476(1) (h) which states 582 "(1) The Commissioner may (h)institute and prosecute any suit or other legal proceeding	 or with the approval of the Standing Committee withdraw from or compromise any suit or any claim for any sum not exceeding five hundred rupees which has been instituted or made in the name of the Corporation or of the Commissioner; It is clear that the phrase "other legal proceedings" includes the power to institute a complaint before a Magistrate and hence it is the Commissioner alone who could exercise the power as there is no other provision in the Act which confers such power on anyone else. This view is supported by the decision of this Court in Bailavdas Agarwala vs J. C. Chakravarty(1) in which it was pointed out that a complaint under The Calcutta Municipal Act	 1923 as applied to the Municipality of Howrah	 would only be filed by the au thorities mentioned therein and not by an ordinary citizen. Section 537 of that Act provided that the Commissioners may institute	 defend or withdraw from legal proceedings under the Act; under section 12 the Commissioners can delegate their functions to the Chairman	 and the Chairman may in his turn delegate the same to the Vice Chairman or to any municipal officer. It was observed in that case that the machinery provided in the Act must be followed in enforcing its provisions	 and it was against the tenor and scheme of the Act to hold that section 537 was merely enabling in nature. The principle invoked in that case was that adopted by the Privy Council in Nazir Ahmad vs King Emperor (2) viz. : that where a power is given to do a certain thing in a certain way	 the thing must be done in that way or not at all. It was	 therefore	 held that if a legal proceeding was instituted under the Municipal Act in question	 it must be done in accordance with the provisions of the Act and not otherwise. But the question presented for determination in the present appeal is somewhat different. Under section 20 of Act 37 of 1954 the prosecution for the offence may be instituted either (a) by the Central Government or the State Government or a local authority or (b) a person authorised in that behalf by general or special order by the Central Government or the State Government or a local authority. Section 2(vii) of Act 37 of 1954 defines a "local authority" to mean "in the case of a local area which is a (1) ; (2) 63 I.A. 372 at 381. 583 pality	 the municipal board or municipal corporation. " A complaint under section 20 of the Act may	 therefore	 be instituted either by the Municipal Corporation or by a person authorised in its behalf by general or special order by the Municipal Corporation. The Resolution of the Delhi Municipal Corporation dated December 23	 1958 reads as follows "Subject : Authorising the Municipal Prosecutor and the Assistant Municipal Prosecutor to launch Prosecutions under section 20 of the . The area under the jurisdiction of the Delhi Municipal Corporation has been declared a "local area" under section 2(vii) of the vide Chief Commissioner 's Notification No	 F.32(30) 58 M and PH(i) dated 13th June	 1958 published in the Delhi Gazette (Part IV) dated 26th June	 1959 and consequently the Municipal Corporation of Delhi is the Local Authority for that area within the meaning of section 2(vii) of the said Act. Section 20 of the contemplates the appointment of persons who shall be authorised to institute prosecutions under this Act by the Local Authority concerned. Shri Sham Sundar Mathur	 M.A.	 LL.B.	 Municipal Prosecutor and Shri Bankey Behari Tawkley	 Assistant Municipal Prosecutor were authorised by the erstwhile Delhi Municipal Committee tinder the above section." "Shri Vijay Kumar Malhotra moved the following resolution	 which was seconded by Shri Prem Sagar Gupta Resolved that the recommendations of the Commissioner vide letter No. 139/Legal/58 dated 1 12 58 regarding authorising the Municipal prosecutor and the Assistant Municipal Prosecutor to launch prosecutions under section 20 of the be approved. The resolution was carried. " In the present case Shri Sham Sundar Mathur	 Municipal Prosecutor filed the complaint under section 20 of Act 37 of 1954 under L14Sup. C.I/69 8 584 the authority given to him by the resolution of the Municipal Corporation. Since the Municipal Corporation	 Delhi	 is a local authority within the meaning of section 20 of Act 37 of 1954 and since it conferred authority on the Municipal Prosecutor the complaint was properly filed by Sham Sundar Mathur. The question is whether the Delhi Municipal Corporation or Shri Mathur was the complainant within the meaning of section 417(3) of the Code of Criminal Procedure. It was argued on behalf of the respondent that the complainant was Shri Sham Sundar Mathur	 the Municipal Prosecutor and the Delhi Municipal Corporation was not competent to make an application for special leave under section 417(3)	 Cr. P.C. We are unable to accept this argument as correct. It is true that Shri Sham Sundar Mathur filed the complaint petition on August 29	 1960. But in filing the complaint Shri Mathur was not acting on his own personal behalf but was acting as an agent authorised by the Delhi Municipal Corporation to file the complaint. It must	 therefore	 be deemed in the contemplation of law that the Delhi Municipal Corporation was the complainant in the case. The maxim qui per alium facit per seipsum facere videtur (he who does an act through another is Jeemed in law to do it himself) illustrates the general doctrine on which the law relating to the rights and liabilities of principal and agent depends. We are	 therefore	 of opinion that Shri Mathur was only acting in a representative capacity and that the Delhi Municipal Corporation was the complainant within the meaning of section 417(3) of the Code of Criminal Procedure and the petition for special leave and the appeal petition were properly instituted by the Delhi Municipal Corporation. For these reasons we allow the appeal	 set aside the judgment of the High Court dated April 9	 1965 and direct that the appeal should be remanded to the High Court for being heard afresh and disposed of according to law. G.C. Appeal allowed.

A complaint under section 7 read with section 16 of the Prevention of Food Adulteration Act	 1964 was filed against the respondent. It was filed by the Municipal Prosecutor who had been authorised to file such complaints by a resolution passed by the appellant corporation under section 20 of the aforesaid Act. On the respondent being acquitted the appellant corporation filed an application in the High Court for special leave to appeal under section 417 of the Code of Criminal Procedure. The application was allowed. When the appeal came up for hearing a preliminary objection was raised by the respondent that the complaint having been filed by the Municipal Prosecutor the corporation was not a 'complainant ' within the meaning of section 417(3) of the Code of Criminal Procedure and therefore special leave to appeal should not have been granted. The High Court upheld the preliminary objection and dismissed the appeal. By special leave the corporation appealed to this Court. HELD : (i) Under section 476(1)(h) of the Delhi Municipal Corporation Act the person competent to institute legal proceedings is the Commissioner. However the present case was governed not by that provision but by section 20 of the Prevention of Food Adulteration Act	 1964 which provides that a prosecution under that Act may be instituted "by the Central Government or the State Government or a local authority or a person authorised in this behalf	 by general or special order by the Central Government or the State Government or a local authority". Section 2(vii) of the Prevention of Food Adulteration Act defines a "local autho rity" to mean "in the case of a local area which is a municipality	 the municipal board or municipal corporation". The Delhi Municipal Corporation was a local authority within the meaning of section 20	 [581 H; 582 C	 G H; 584 A] (ii)The Municipal Prosecutor had filed the complaint against the respondent under authority given to him by the resolution of the Delhi Municipal Corporation under section 20 of the Prevention of Food Adulteration Act. in filing the complaint the said prosecutor was not acting on his own personal behalf but was acting as an agent authorised by the Delhi Municipal Corporation to file the complaint. It must therefore be deemed in law that the Delhi Municipal Corporation was the 'complainant ' in the case	 for according to the Latin maxim. "One who does an act through another is deemed in law to do it himself." [583 H; 584 C D] Being thus the complainant in the case the appellant Corporation could properly file the application under section 417 of the Code of Criminal Procedure. [Case remanded to High Court for disposal according to law.] [584 E] 580 Ballavdas Agarwala vs J. C. Chakravarty	 [1962] 3 S.C.R. 739 and Nazir Ahmad vs King Emperor	 63 I.A. 372 as 381	 referred to.
