158-BC (c), which goes as follows:“The Assessing Officer, on determination of the undisclosed income of the block period in accordance with this Chapter, shall pass an order of assessment and determine the tax payable by him on the basis of such assessment”. Reference to Section 143(3) is merely procedural. There are various Sections in the Act under which assessment are completed like Section 147, Section 158-BC etc. But in the assessment order, along with Section 147/Section 158-BC, Section 143(3) is also referred. Similarly to give effect to C.I.T's order under Section 263 or 264 or C.I.T.(A)'s order under Section 251 or I.T.A.T. Order under Section 254, Section 143(3) is used as “Read with Section”. In this case, the core Section under which the assessment is completed under Chapter XIV-B is under Section 158-BC(c) r.w.s. 158-BD. There has been so many decisions wherein the Courts have held that regular assessments under Chapter XIV and Block assessment under Chapter XIV-B are parallel and can be proceeded simultaneously and independently. In this case for the Assessment Year 1996-97 and 1997-98 no regular assessment has been completed under Section 143(3) or 147 earlier and therefore as mentioned in my last letter dated 28.10.2003, Your case is covered under Section 151(2) of the I.T. Act, 1961. Your objection that notice is beyond jurisdiction is therefore rejected.”
