Summarize the following court judgment. ivil Appeal No. 544 of 1975. From the Judgment and Order dated 20.8. 1973 of the Gujarat High Court in Special Civil Application No. 631 of 1970. C.M. Lodha and Miss Subhashini for the Appellant. The Judgment of the Court was delivered by RANGANATH MISRA	 J. This is an appeal by the Revenue by special leave and is directed against the judgment of the Gujarat High Court dated August 20	 1973 in a writ petition. The High Court quashed the notice for reassessment issued under section 147(b) of the Income tax Act	 1961 (hereinaf ter referred to as 'the Act ') for the assessment year 1965 66. Inspite of service of notice	 the assessee respondent has not appeared. The High Court has quashed the notice by accepting the assessee 's contention that the action of the Income tax Officer was barred by limitation prescribed by the Act. There is no dispute that the notice in this case under section 147(b) of the Act was issued by registered post on March 31	 1970	 and was received by the assessee on April 3	 1970. To the facts of the case	 section 147(b) of the Act applies. The two relevant provisions are in sections 148 and 149 of the Act which provide: "148(1) Before making the assessment	 reas sessment or recomputation under section 147	 the Income tax Officer shall serve on the assessee a notice containing all or any of the requirements which may be included in a notice under sub section (2) of section 139; and the provisions of this Act shall	 so far as may be	 apply accordingly as if the notice were a notice issued under that sub section. 44 (2). . . . . . . "149(1) No notice under section 148 shall be issued	 (a). . . . . . . (b) In cases falling under clause (b) of section 147	 at any time after the expiry of four years from the end of the relevant as sessment year. (2) The provisions of sub section (1) as to the issue of notice shall be subject to the provisions of section 151." The High Court relied upon the decision of this Court in the case of Banarsi Debi & Anr. T. 0.	 District IV	 Cal cutta & Ors.	 where the validity of a notice under section 34(1) of the Incometax	 Act	 1922 and the scope of section 4 of the Income tax (Amendment) Act of 1959 by which sub section (4) was introduced into section 34 were considered. This Court indicated	 keeping the provisions of section 34 in view	 that there was really no distinction between "issue" and "service of notice". Section 34	 sub section (1) as far as relevant provided thus: "34(1) If (a). . . . . . . (b) . . he may in cases falling under clause (a) at any time within 8 years and in cases falling under clause (b) at any time within four years at the end of that year	 serve on the assessee	 . . and may proceed to assess or reassess such income . . ." Section 34	 conferred jurisdiction on the Income tax Officer to reopen an assessment subject to service of notice within the prescribed period. Therefore	 service of notice within limitation was the foundation of jurisdiction. The same view has been taken by this Court in Janni vs Indu Prasad Bhat	 as also in C.I.T. vs Robert	 The High Court in our opinion went wrong in relying upon the ratio of in disposing of the case in hand. The scheme of the 1961 Act so far as notice for reassessment is concerned is quite different. What used to be contained in section 34 of the 1922 Act has been spread out into three sections	 being sections 147	 148 and 149 in the 45 1961 Act. A clear distinction has been made out between 'issue of notice ' and 'service of notice ' under the 1961 Act. Section 149 prescribe the period of limitation. It categorically prescribes that no notice under section 149 shall be issued after the prescribed limitation has lapsed. Section 148(1) provides for service of notice as a condition precedent to making the order of assessment. Once a notice is issued within the period of limitations	 jurisdiction becomes vested in the Income tax Officer to proceed to reassess. The mandate of section 148(1) is that reassessment shall not be made until there has been service. The require ment of issue of notice is satisfied when a notice is actu ally issued. In this case	 admittedly	 the notice was issued within the prescribed period of limitation as March 31	 1970	 was the last day of that period. Service under the new Act is not a condition precedent to conferment of jurisdic tion in the Income tax Officer to deal with the matter but it is a condition precedent to making of the order of as sessment. The High Court in our opinion lost sight of the distinction and under a wrong basis felt bound by the judg ment in As the Income tax Officer had issued notice within limitations	 the appeal is allowed and the order of the High Court is vacated. The Income tax Officer shall now proceed to complete the assessment after complying with the requirements of law. Since there has been no ap pearance on behalf of the respondents	 we make no orders for costs. A.P.J. Appeal allowed.

The respondent challenged the notice for reasessment issued under section 147(b) of the Income Tax Act	 1961 for the assessment year 1965 66. The High Court quashed the notice holding that the action of the Income Tax Officer was barred by limitation prescribed by the Act. Allowing the appeal of the Revenue	 HELD: 1. The scheme of the 1961 Act so tar as notice for reassessment is concerned is quite different. What used to be contained in section 34 of the 1922 Act has been spread out into three sections	 being sections 147. 148 and 149 of the 1961 Act. A clear distinction has been made out between "issue of notice" and "service of notice" under the 1961 Act. Section 149 prescribes the period of limitation. It categor ically prescribes that no notice under section 148 shall be issued after the prescribed limitation has lapsed. Section 148(1) provides for service of notice as a condition prece dent to making the order of assessment. Once a notice is issued within the period of limitations	 jurisdiction be comes vested in the Income Tax Officer to proceed to reas sess. The mandate of section 148(1) is that reassessment shall not be made until there has been service. The requirement of issue of notice is satisfied when a notice is actually issued. Banarsi Debi & Anr. vs L T.O. District IV	 Calcutta & Ors.	 ; Janni vs Indu Prasad Bhat	 and C.I.T. vs Robert	 	 distinguished. In the instant case	 notice was issued within the prescribed period 43 of limitation as March 31	 1970 was the last day of that period. Service under the new Act is not a condition prece dent to conferment of jurisdiction in the Income Tax Officer to deal with the matter but it is a condition precedent to making of the order of assessment. The High Court lost sight of the distinction and under a wrong basis felt bound by the judgment in Banarsi Debi & Anr. T. 0.	 District IV	 Calcutta & Ors.	 ( As the Income Tax Officer had issued notice within limitation the order of the High Court is vacated.
