Summarize the following court judgment. CTION: Civil Appeal No. 460 of 1970. Appeal by special leave from the judgment and order dated May 20	 1969 of the Allahabad High Court in Special Appeal No. 1177 of 1968. M. C. Chagla and R. Gopalakrishnan	 for the appellant. V. A. Seyid Muhammad	 P. C. Chandi	 B. D. Sharma and section P. Nayar	 for the respondents. The Judgment of the Court was delivered by Grover	 J. This is an appeal by special leave from a judgement of the Allahabad High Court dismissing a writ petition by which the appellant challenged the validity of a warrant issued by the Assistant Collector	 Central Excise	 Allahabad	 authorising the Superintendent Central Excise	 Varanasi	 to enter certain premises	 search the same and seize the documents therefrom. The appellant	 which is a public limited company having its registered office at Calcutta	 owns and runs a factory known as Sahu Chemicals and Fertilisers at Varanasi where chemicals such 94 as ammonia and soda ash are manufactured. In February 1962 excise duty was fixed on manufacture of ammonia for the purpose of fertilisers at Rs. 25/ per metric ton	 the rate being Rs. 125/ per metric ton if it was used for other purposes. The notification by which the aforesaid duty was payable was later withdrawn by means of another notification dated March 1	 1964 and thereafter no excise duty was required to be paid on the manufacture of ammonia. For the period from May 1962 to the beginning of March 1964 the appellant had paid duty at the rate of Rs. 25/ per metric ton on the ground that ammonia had been utilised for the purpose of manufacture of chemical fertiliser. The Central Excise authorities	 however	 had received information that part of the ammonia had been utilised for purposes other than the manufacture of fertilizers on which higher duty of Rs. 125/ per metric ton was payable. It was considered that there had been evasion of duty. On May 11	 1968	 the Assistant Collector issued a warrant for the search and seizure of goods and documents pursuant to which the premises of the factory at Varanasi were searched on May 11	 12 and 13	 1968 and various documents were seized. The writ petition was heard in the first instance by the learned single judge who dismissed it. In appeal his judgment was upheld by the Division Bench. Three contentions were raised before the Division Bench; the first was that section 1.2 of the 	 hereinafter called	 the "Act" was void as the powers delegated to the Central Government by the legislature were excessive and beyond permissible limits. The second point was that the having been repealed it was not open to the Central Government under section 12 of the Act to apply section 105(1) of the to the Act and the notification dated May 4	 1963 by which this was done was illegal and ultra vires. The	 third was that the search and seizure made by the respondents under the impugned authorisation dated August 11	 1968 and the authorisation itself were not in accordance with the provisions of section 105 of the . Section 12 of the Act is in the following terms: section 12. Application of the provisions of Act VIII of 1878 to Central Excise Duties. The Central Government may	 by notification in the official Gazette declare that any of the provisions of the relating to the levy on and exemption from customs duties	 drawback of duty	 warehousing offences and penalties	 confiscation	 and procedure relating to offences and appeals	 shall	 with such modifications and alterations as it may consider necessary or desirable to adapt them to the circumstances	 be applicable in regard to 95 like matters in respect of the duties imposed by section 3. " When the Act was enacted section 172 of the which could be applied to the Act under section 12 provided : S.172. "Any Magistrate may	 on application by a Customs Collector	 stating his belief that dutiable or prohibited goods (or any documents relating to such goods) are secreted in any place within the local limits of the	 jurisdiction of such Magistrate	 issue a warrant to search for such goods. Such warrant shall be executed in the same way and shall have the same effect	 as a search warrant issued under the law relating to Criminal Procedure. " It may be mentioned that the words "or documents" were inserted by the Sea Customs Amendment Act 1955. After the enactment of the by the notification dated May 4	 1963 as amended by the Notification dated February 6	 1965 amongst other provisions of the 	 sub section (1) of section 105 and section 1	 IO were made applicable with certain modifications of a minor nature under section 12 of the Act. The material part of these sections are reproduced below ; "section 105(1) Power to search premises. (1) if the Assistant Collector of Customs	 or in any area adjoining the land frontier or the coast of India an officer of Customs specially empowered by name in this behalf by the Board	 has reason to believe that any goods liable to confiscation or any documents or things which in his opinion will be useful for or relevant to any proceeding under this Act are secreted in any place	 he may authorise any officer of customs to search or may himself search for such goods	 documents or things." "section 110(3). The proper officer may seize any document or things which	 in his opinion	 will be useful for	 or relevant to	 any proceeding under this Act. " On the first point it has been urged on behalf of the appellant that section 12 of the Act gave unrestricted and unlimited power to the Central Government to modify or alter the provisions of the and to apply the provisions of that Act with such modifications and alterations as the Central Government might consider appropriate. Modification	 it has been pointed out	 may be permissible	 and may not fall within the vice of excessive delegation because the basic structure is not changed but alteration	 it is suggested	 has a much wider connotation and it emm 96 braces even the changing of the essential pattern of a thing or object. Such a power inherently involves the making of changes even in regard to matters pertaining to legislative policy. In our opinion the above contention is purely of academic interest in the present case. In the notifications which were issued applying	 inter alia	 section 105 (1) and section 1 10 of the no such changes have been made as can possibly fall within the meaning of the word "alterations". It has been pointed out in the previous decisions of this Court that the power to restrict and modify does not import the power to make essential changes. It is confined to alterations of a minor character and no change in principle is involved. See In re Delhi Laws Act	 1912.(1) It was conceded before the High Court and has not been urged before us that the word "modifications" could not be taken as con ferring on the Central Government any legislative power which was in excess of the permissible limits. Objection was taken only with regard to the word "alterations" but that word must be understood in the sense in which it was open to the legislature to employ it legitimately and in a constitutional manner. No question is thus involved of delegation either of any essential legislative functions or any change of legislative policy. The second contention has hardly any merit. Section 8(1) of the General Clauses Act provides that where any Central Act repeals and re enacts with or without modification any provision of a former enactment then references in any such enactment or in any instrument to the provision so repealed shall	 unless a different intention appears	 be construed as references to the provision so re enacted. By virtue of this provision it cannot be disputed. that in section 12 of the Act the can be read in place of the . An attempt has been made to argue that section 12 of the Act empowers incorporation of the provisions of in the Act itself and whenever a notification is issued under it such provisions of the as have been applied become incorporated as in integral part of the Act. Section 8 of the General Clauses Act would not be applicable to a case of such incorporation and it can only apply if section 12 can be regarded as containing a reference to the provisions of the . In Secretary of State for Indian in Council vs Hindusthan Cooperative Insurance Society Ltd. (2) it was accepted as a settled rule of construction that where a statute is incorporated by reference into a second the repeal of the first statute does not affect the second. The law laid down by the Privy Council can have no applicability to the present case. Section 12 of the Act did not bodily lift	 as it were	 certain provisions of the and incorporate (1) ; (2) 58 I.A.259. 97 them as an integral part of the Act. It only empowered the Central Government to apply the provisions of the with such modifications and alterations as might be considered necessary or desirable by the Central Government for the purpose of implementation and enforcement of section 3 of the Act. No exception could be taken to the view of the High Court that section 12 contained a provision delegating limited powers to the Central Government to draw upon the provisions of the for the purpose of implementing section 3 of the Act. in The Collector of Customs	 Madras vs Nathella Sampathu Chetty & Another(1) this Court examined at length the meaning and effect of incorporation by reference of one statute into another and discussed the Privy Council case referred to before in detail. Section 8(1) of the General Clauses Act	 it was pointed out	 'dealt with reference or citation of one enactment in another without incorporation. The usual or recognised formulae generally employed to effect incorporation were considered; for instance the words used in section 20 of 53 and 54 Vict. 70 Housing of the Working Classes Act	 1890	 the words used were " shall	 for that purpose	 be deemed to form part of this Act in the same manner as if they were enacted in the body thereof." In 54 and 55 Vict. 19	 section 1(3)	 the language employed was	: "The provisions of section 134 of the said Act (set out in the schedule) shall apply as if they were herein enacted. " It is unnecessary to mention the other provisions because a comparison of the recognised formulae with the text of section 12 of the Act shows that the provisions of the were not meant to be incorporated in the Act and were only to be applicable to the extent notified by the Central Government for the purpose of the duty leviable under section 3. Another aspect which has been presented under the second contention is that the impugned notification is bad and stands vitiated because under the previous notification which applies section 172 of the it was a Magistrate who had to bring his judicial mind to bear on the expediency or desirability of issuing a warrant for search whereas under the present notification after the enactment of the it is the Assistant Collector of Customs who performs executive functions and who has been empowered to issue the warrant for search and seizure. The decision of this Court in Collector of Customs & Excise. Cochin & Ors. vs A. section Bava(2) has been sought to be pressed into service in support of the argument that extension of section 105 (1)	 (1) ; (2) 98 is illegal. In that case the provisions of section 129 of the had been applied under section 12 of the Act. Section 129 dealt with the procedure relating to appeals and required an appellant to deposit pending the appeal the duty or penalty imposed and empowered the appellate authority	 in its discretion	 to dispense with such deposit pending the appeal in any particular case. There was a provision in the Act itself	 section 35	 which gave an unfettered right of appeal to a person aggrieved by any decision or order made under the Act. It was in these circumstances that it was held that section 129 of the could not be made applicable so as to whittle down the substantive right of appeal conferred by section 35 of the Act. The ratio of that decision can afford no assistance to the appellant in the present case. By the notification issued under section 12 of the Act after the enactment of 	 the previous notification under the stood superseded and no question survives with regard to the validity of the notification issued in 1963 and amended in 1965. On the third point an attempt was made to argue that the Assistant Collector	 while issuing the	 warrant for search and seizure did not apply his mind to the relevant and necessary facts. Our attention has been invited to the warrant itself in which the documents have not been particularised or specified but the words certain documents" have been used. The learned single judge dealt with this matter fully and repelled the contention that there was no relevant material before the authority upon which the belief could be founded in terms of section 105(1) of the by the Assistant Collector. We find no merit in this contention. The appeal fails and it is dismissed with costs. G.C. Appeal dismissed.

The appellant company had a factory at Varanasi at which chemicals including ammonia were manufactured. It was considered by the Central Excise authorities that there had been evasion of duty on ammonia by the company. The Assistant Collector Central Excise issued a warrant for search and seizure of goods and documents	 pursuant to which the premises of the aforesaid factory were raided in May	 1968 and certain documents seized. The company filed a writ petition in the High Court which was dismissed by the Single Judge. The Division bench upheld the order of the Single Judge. In appeal to this Court by special leave	 the questions that fell for consideration were (i) Whether section 12 of the Central Excise Act was void because the powers delegated to the Central Government thereby including the power to make alterations in the Act applied were excessive; (ii) Whether the Sea Customs Act	 1875 having been re pealed	 it was open thereafter to the Central Government under section 12 of the Excise Act to apply section 105 of the ; and (iii) Whether the Assistant Collector issued the warrants in the present case after due application of mind to relevant materials and 'facts in terms of section 105(1) of the . HELD : (i) In the notifications issued inter alia applying section 105(1) and section 1 10 of the 	 no such changes had been made as could possibly fall within the meaning of the word 'alterations. The power to restrict and modify does not import the power to make essential changes. It is confined to alterations of minor character and no change in principle is involved. The word 'alteration ' in section 12 must be understood in the sense in which it was open to the legislature to employ it legitimately and in a constitutional manner. No question was thus involved of delegation either of any essential legislative functions or any change of legislative policy. [96 B D] In re ; 	 	 referred to. (ii)S. 8(1) of the General Clauses Act provides that where any Central Act repeals and re enacts with or without modification any provision of the former enactment then references in any such enactment or in any instrument	 to the provisions so repealed shall	 unless a different intention appears	 be construed as references to the provisions so re 93 enacted. By virtue of this provision it could not be disputed that in section 12 of the Central Excise and Salt Act	 1947	 the can be read in place of the . [96 E] The contention that section 12 of the Act empowers incorporation of the provision of the in the Act itself and	 therefore	 8(1) of the General Clauses Act	 does not apply could not be accepted. Section 12 only contained a provision delegating limited powers to the Central Government to draw upon the provisions of the for the purpose of implementing section 3 of the Act. A] Secretary of State for India in Council vs Hindusthan Co operative Insurance Society	 58 I.A. 259	 distinguished; The Collector of Customs Madras vs Nathella Sampatha Chetty The extension of section 105 could not be said to be illegal merely because under section 172 of the it was a Magistrate who after applying judicial mind had to issue search warrant whereas under the present notification after the enactment of the 	 it was the Assistant Collector of Customs performing executive functions who had been empowered to issue a search warrant. By the latter notification the previous notification applying the provisions of the was superseded and no question with regard to the validity of the notification issued in 1963 and then amended in 1965 could survive. Collector Custom & Excise Cochine & Ors	 vs A. section Bava 	 distinguished [98 A C] (iii)On the facts of the case it could not be said that the Assistant Collectorhad no relevant material upon which the belief could be founded in termsof section 105(1) of the
