Summarize the following court judgment. ivil Appeal No. 161 Of 1986. From the Judgment and Order dated 17.9.85 of the Customs Excise and Gold (Control) Appellate Tribunal	 New Delhi in Appeal No. ED(SB) (T) 463/84 D. Soli J. Sorabjee	 Ravinder Narain	 Harish Salve	 section Ganesh and P.K. Ram for the Appellant. B. Datta	 Additional Solicitor General	 Mrs. Indra Sawhney and Ms. section Relan for the Respondent. The Judgment of the Court was delivered by RANGANATH MISRA	 J. The fate of this appeal under sec tion 35(L) of the 	 de pends upon the meaning and scope of the Explanation appear ing in section 11A of the Act. The High Court of Karnataka by its order dated 4.6.1976 in Writ Petition No. 2632 of 1976 gave the following direc tion: 311 "Pending disposal of the aforesaid writ Peti tion	 it is ordered by this Court that collec tion of excise duty as a fabric be and the same is hereby stayed. It is further ordered that the petitioner shall however continue to pay exercise duty as yarn and shall further maintain an account in square metres for future clearance." The said Writ Petition was ultimately dismissed by the High Court on 16.2. The operative part of the Court 's final order ran thus: "For the reasons aforesaid	 we make the fol lowing order: (i) Rule discharged; (ii) We decline to interfere at this stage leaving open to the petitioner to urge all the contentions in reply to the show cause notices. " On 20th May	 1982	 a notice to show cause was issued to the appellant by the Assistant Collector	 being Notice No. 913	 and with this the Collector sought to raise a demand for the period from 20th June	 1976 to 28th February	 1981 apart from for the period between 1.4. 1975 to 18.8.1975 in respect of which an earlier show cause notice dated 29.1. 1976 had already been issued. It is not disputed by the Revenue that the appropriate period of limitation to apply to the facts of the case is six months as provided in section 11A of the Act and that the Notice issued on 20th of May	 1982 was beyond that period. Reliance was placed on the Explanation for obtaining extension of that period. The Explanation reads thus: "Where the service of the notice is stayed by an order of a Court	 the period of such stay shall be excluded in computing the aforesaid period of six months or five years	 as the case may be." The provision in the Explanation incorporates a well known principle of law. Section 15 of the Limitation Act of 1908 (also of Section 15 of the Limitation Act of 1963) incorpo rates the same principle. This Court in Sirajul Haq Khan & others vs The Sunni Central Board of Waqf	 U.P. & others	 dealt with the effect of an order of injuc tion in the matter of computation of limitation. At page 1302 of the Reports	 Gajendragadkar	 J. as he then was	 spoke for the Court thus. 312 "It is plain that	 for excluding the time under this section	 it must be shown that the institution of the suit in question had been stayed by an injunction or order; in other words	 the section requires an order or an injunction which stays the institution of the suit. And so in cases falling under Section 15	 the party instituting the suit would by such institution be in contempt of court. But in our opinion	 there would be no justifi cation for extending the application of section 15 on the ground that the institution of the subsequent suit would be inconsistent with the spirit or substance of the order passed in the previous litigation . . " In the instant case	 the order of stay passed by the Karna taka High Court had only stayed the collection of the excise duty	 which is a stage following levy under the scheme of the Act. Obviously there was no interim direction of the High Court in the matter of issue of notice for the purpose of levy of duty. The relevant portion of Section 11A provid ed. "(1) When any duty of excise has not been levied or paid or has been short levied or short paid or erroneously refunded	 a Central Excise Officer may	 within six months from the relevant date	 serve notice on the person chargeable with the duty which has not been levied or paid or which has been short levied or short paid or to whom the refund has erro neously been made	 requiring him to show cause why he should not pay the amount specified in the notice: (2) The Assistant Collector of Central Excise shall	 after considering the representation	 if any	 made by the person on whom notice is served under sub section (1)	 determine the amount of duty of.excise due from such person (not being in excess of the amount specified in the notice) and thereupon such person shall pay the amount so determined. ' ' Reference to Section 3 of the Act which contains the charg ing provision clearly shows that levy and collection are two distinct and separate 313 steps. This Court in N.B. Sanjana	 Assistant Collector of Central Excise	 Bombay & Ors. vs Elphinstone Spinning & Weaving Mills Co. Ltd.	 ; 	 at page 514 stat ed: " . The charging provision section 3(i) specifically says "there shall be levied and collected in such a manner as may be pre scribed the duty of excise . . "It is to be noted that sub section (i) uses both the expressions "levied and collected" and that clearly shows that the expression "levy" has not been used in the Act or the Rules as meaning actual collection." The High Court having directed stay of collection had	 therefore	 not given any interim direction in the matter of issue of notice or levy of the duty. The Explanation in clear terms refers to stay of service of notice. The order of the High Court did not at all refer to service of notice. Therefore	 there is force in the submission of the appellant that the benefit of the Explanation is not available in the facts of the case. No notice seems to have been issued in this case in regard to the period in question. Instead thereof an out right demand had been served. The provisions of Section 11A (1) and (2) make it clear that the statutory scheme is that in the situations covered by the sub section (1)	 a notice of show cause has to be issued and sub section (2) requires that the cause shown by way of representation has to be considered by the prescribed authority and then only the mount has to be determined. The scheme is in consonance with the rules of natural justice. An opportunity to be heard is intended to be afforded to the person who is likely to be prejudiced when the order is made	 before making the order thereof. Notice is thus a condition precedent to demand under sub section (2). In the instant case	 compliance with this statutory requirement has not been made	 and	 there fore	 the demand is in contravention of the statutory provi sion. Certain other authorities have been cited at the hearing by counsel for both sides. Reference to them	 we consider	 is not necessary. The appeal has to be allowed and the demand raised for the period 19.8.1975 to 23.2.1981 has to be set aside. There shall be no order for costs. The tax paid	 if any	 shall be refunded to the appellant. S.R. Appeal al lowed.

A show cause notice dated 29.1.1976 issued by the re spondent to the appellant calling upon him to explain as to why excise duty treating his product as "fabric" and not as "yarn" may not be levied	 was challenged in the High Court of Karnataka in Writ Petition No. 2632/ 1976. Pending final disposal of the writ petition	 an interim order staying the collection of excise duty as a "fabric" for the period 1.4.1975 to 18.8.75 alone was passed with a specific direc tion that the appellant should continue to pay excise duty as "yarn". Finally the writ petition was dismissed on 16.2.1981. On 20th May	 1982	 another notice No. 913 to show cause was issued to the appellant simultaneously seeking to raise a demand for the period from 20.6.1976 to 28.2.1981 apart from for the period between 1.4.1975 to 18.8.1975 challenged in the earlier writ petition. The Karnataka High Court having rejected the plea of bar of limitation under section 11A of the raised in the writ petition challenging the said second show cause notice and demand	 the appellant has come in appeal by way of special leave. Allowing the appeal	 the Court	 HELD: 1.1 Section 3 of the Act which contains the charg ing provision clearly shows that levy and collection are two distinct and separate steps. [312H] 1.2 The provision of section 11A(1) and (2) of the make it clear that the statutory scheme is that in the situations covered by the sub section(1)	 a notice of show cause has to be issued and sub section(2) requires that the cause shown by way of representation has to be considered by the prescribed au thority and then 310 only the amount has to be determined. The scheme is in consonance with the rules of natural justice. An opportunity to be heard is intended to be afforded to the person who is likely to be prejudiced when the order is made	 before making the order thereof. Notice is thus a condition prece dent to a demand under sub section(2). In the instant case	 compliance with this statutory requirement has not been made	 and	 therefore	 the demand is In contravention of the statutory provision. [313E G] 2. Explanation to section 11A of the 	 which incorporates a well known principle of law	 in clear terms refers to 'stay of service of notice '. The High Court order did not at all refer to service of notice. The High Court having directed stay of collection of duty as 'fabric ' has not issued any interim direction in the matter of issue of notice of levy of the duty. Therefore	 the benefit of Explanation to section 11A of the Act is not available to the Respondent. [313C D] Sirajul Haq Khan & Ors. vs The Sunni Central Board of Waqf	 U.P. & Ors. 	 ; and N.B.
