(iv) Mr. Sridharan, learned Senior Counsel for the Assessee very fairly concedes that this issue, is no longer res integra. In fact, it stands concluded in favour of the Appellant-Revenue and against Respondent-Assessee by the decision of the Supreme Court in Fibre Boards Pvt. Ltd., v/s. CIT 10 SCC 333 an d Shree Bhagawati Steel Rolling Mills v/s. CCE 326 ELT 209 . In both the aforesaid decisions, the Apex Court held that omission/ substitution would fall within the ken of a repeal of a provision. It further held that the earlier decision of the Apex Court in this aspect by M/s. Rayala Corporation (P) Ltd. (supra) and Kolhapur Canesugar Mills Pvt.

Tulloch & Co., 1964 (SC) 1284. It thus held that omission would be included in the meaning of repeal. In the light of the above, Section 38A of the Act (inserted in 2001 with retrospective effect from 1944) will make the notice dated 17th January, 2000 valid even post 1st April, 2000. This is in view of Section 38A (c) of the Act which states that any amendment, repeal, supersession or rescinding shall not affect any right, privilege, obligation or liability acquired, accrued or incurred under any rule so amended, repealed, superseded or rescinded. This is further qualified by providing that any investigation, legal proceedings may be continued, as if the Rule had not been
