The judgment of the court was delivered by 
       R. Sudhakar J.- The assessee has filed this appeal under section 260A of  the Income-tax Act, 1961 challenging the order of the Income-tax Appellate  Tribunal, "A" Bench, Chennai, dated October 23, 2007, made in I. T.  A. No. 530/Mds/2006 for the assessment year 2002-03, and the same was admitted  on the following questions of law :
      "(i) Whether the Tribunal was right in holding that  the deferred revenue expenditure in the aggregate incurred by the assessee  towards the product development is not allowable ?
       (ii) Whether the Tribunal was right in holding that the  deferred revenue expenditure claimed by the assessee is not allowable in terms  of the Explanation to section 35 of the Income-tax Act ?
       (iii) Whether the Tribunal was right in holding that the  assessee is not entitled to the deduction of the prior year's expenditure  forming part of the deferred revenue expenditure even though, such a claim is  allowable in law as per the decision of the Supreme Court in the case of Madras  Industrial Investment Corporation Ltd. v. CIT [1997] 225 ITR 802 (SC) ?
       2.1.The facts in a nut-shell are as under : The appellant  is a private limited company engaged in the business of manufacture of  telecommunication products, research and development in telecommunication  products, software development and support services. The assessee filed return  of income admitting total loss of Rs. 5,26,38,410. The return was processed  under section 143(1) of the Act and, subsequently, the case was selected for  scrutiny and notice under section 143(2) of the Act was issued. In response to  the said notice, the assessee's representative appeared in person and furnished  various details as sought for during the course of scrutiny :
       2.2. It is not in dispute that the business of the assessee  commenced even prior to the financial year 1999-2000. The claim of the assessee  under the head deferred research and development expenses is set out in the  assessment order as follows :
      
        
          
            |   | 1999-2000 | 2000-01 | 2001-02 | 
          
            | Balance at the commencement of the year Addition during    the year | -7,631,487
 | 7631,487 13,556,259 | 19,298,564 3,444,649 | 
          
            |   | 7,631,487 | 21,187,746 | 22,743,213 | 
          
            | Less : Written off during the year | - | 1,889,182 | 22,743,213 | 
          
            | Balance at the close of the year | 7,631,487 | 19,298,564 | - | 
        
       
      2.3. In the financial year 2000-01 (assessment year  2001-02), only a sum of Rs. 18,89,182 was claimed as expenditure to be written  off during the year, even though the total expenditure during the year was to  the tune of Rs. 1,35,56,259. The assessee carried forward the expenditure to  the next financial year 2001-02 (assessment year 2002-03) and claimed the  expenditure to the tune of Rs. 2,27,43,213, of which only a sum of Rs. 34,44,649  was allowed by the Assessing Officer, while completing the assessment under  section 143(3) of the Act by an order dated February 25, 2005. The Assessing  Officer disallowed the claim of expenditure relating to Rs. 1,92,98,564 stating  that there is no provision for carrying forward such expenditure. In brief, the  finding of the Assessing Officer is as follows :
       "It will be seen from the above details that the  assessee has incurred expenses of Rs. 76,31,487 in the financial year  1999-2000. Rs. 1,35,56,259 in the financial year 2000-01 and Rs. 34,44,649 in  the financial year 2001-02. In the lengthy submissions made by the asses see,  the assessee has only stated as to how the product was developed and what is  its utility and the market potentiality. However, there is no explanation as to  why the expenses were written off in one year and as to why the research and  development expenses which fall under the purview of section 35 have been  deferred. In the formal discussion it was, however, stated that since new  technologies are being developed in their field the product technology has  become obsolete and, therefore, it was decided to write off the whole expenses.
       A careful study of the assessee's submissions and the close  look at the details of expenses would reveal that none of the expenses  mentioned in the list are of capital nature. The same were also stated to have  been incurred on research and development. It is also stated that the company  was developing a technology for its new product known as DIAS. The assessee in  the background of the submissions has admitted the fact that during the year  the company was close on the completion of the development of their product and  the necessary field trials of the product were completed. This very revelation  indicate that the expenses made by the assessee were made for research and  developments, they, therefore, very much fall under the purview of section 35.  As per the submissions made by the assessee, the assessee has written off Rs. 18,89,182  for the financial year 2000-01 relevant to the assessment year 2001-02. The  balance is treated as deferred scientific expenditure. There is no concept like  deferred scientific research expenses in the Income-tax Act. The research and  development expenses as envisaged under section 35 of the Income-tax Act and as  relevant to the assessee's case states as under :
       '(1) In respect of expenditure on scientific research, the  following deductions shall be allowed-
        (i) any expenditure (not being in the nature of capital  expenditure) laid out or expended on scientific research related to the  business.
       Explanation.-Where any such expenditure has been laid out  or expended before the commencement of the business (not being expenditure laid  out or expended before the 1st day of April, 1973) on payment of any salary [as  defined in Explanation 2 below sub-section (5) of section 40A] to an employee  engaged in such scientific research or on the purchase of materials used in  such scientific research, the aggregate of the expenditure so laid out or  expended within the three years immediately preceding the commencement of the  business shall, to the extent it is certified by the prescribed authority to  have been laid out or expended on such scientific research, be deemed to have  been laid out or expended in the previous year in which the business is  commenced ;'
       Here in this, the assessee's business has already commenced  and, therefore, the Explanation to section 35 is not applicable to the asses see.  Looking to the nature of expenses the same does not include any expenditure  towards acquisition of any capital asset and, therefore, as per the provisions  of the Act if at all it was an expenditure on research and development the same  ought to have been claimed in the year in which it was actually incurred. The  assessee has not done so. As the assessee-company itself has admitted these  expenses as expenses on research and development and there is no concept of  deferred expenses under section 35 only those expenses which relate to the year  under consideration can be allowed to the assessee. I accordingly restrict the  assessee's claim only to the extent of Rs. 34,44,649. The balance expenses of  Rs. 1,92,98,564 are disallowed as not pertaining to this year and added to the  assessee's total income." (emphasis supplied)
       2.4. Calling into question the assessment order, the  assessee preferred an appeal before the Commissioner of Income-tax (Appeals).  The Commissioner of Income-tax. (Appeals), while concurring with the findings  of the Assessing Officer, dismissed the appeal holding that the expenditure  incurred by the assessee on research and development falls within the purview  of section 35 of the Act and since the business of the assessee has already  commenced, the expenditure shall be allowed only in the year in which it was  incurred.
       2.5. Aggrieved by the said order, the assessee appealed to  the Tribunal. The Tribunal observed that since the business of the assessee had  already commenced, the assessee cannot come within the purview of the  Explanation to section 35 of the Act. It was also observed that the expenses  relatable to the year under consideration were duly allowed by the Assessing  Officer and only the expenditure not relatable to the relevant year of assessment  was disallowed. The Tribunal held that the assessee failed to produce any  evidence to demonstrate that the expenditure claimed is relatable to the year  under consideration. Thus, the Tribunal upheld the orders passed by the  authorities below.
       2.6. Assailing the said order, the assessee has preferred  this appeal on the questions of law referred to supra.
       3. We have heard Mr. K. Magesh, learned counsel for the  appellant and Mr. T. Ravi Kumar, learned senior standing counsel appearing for  the revenue and perused the orders passed by the Tribunal and the authorities  below.
       4. Before adverting to the merits of the case, it would be  apposite to refer to section 35(1)(i) of the Act and the Explanation thereto,  which are as under :
"35. Expenditure on scientific research.-(1) In  respect of expenditure on scientific research, the following deductions shall  be allowed-
        (i) any expenditure (not being in the nature of capital  expenditure) laid out or expended on scientific research related to the  business ;
       Explanation.-Where any such expenditure has been laid out  or expended before the commencement of the business (not being expenditure laid  out or expended before the 1st day of April, 1973) on payment of any salary (as  defined in Explanation 2 below sub-section (5) of section 40A) to an employee  engaged in such scientific research or on the purchase of materials, used in  such scientific research the aggregate of the expenditure so laid out or  expended within the three years immediately preceding the commencement of the  business shall, to the extent it is certified by the prescribed authority to  have been laid out or expended on such scientific research, be deemed to have  been laid out or expended in the previous year in which the business is  commenced." (emphasis supplied)
        5. With regard to the second question of law, namely,  whether the Tribunal was right in holding that the deferred revenue expenditure  claimed by the assessee is not allowable in terms of the Explanation to section  35 of the Act, the learned counsel for the assessee fairly states that the  business of the assessee has commenced long prior to the relevant assessment  year and, therefore, he is not canvassing the said question of law. In view of  the fair submission made by the learned counsel for the assessee, we do not  propose to answer the same in this appeal.
       6. Apropos the first question of law, on a plain reading of  section 35 of the Act, we are unable to accept the plea of the learned counsel  for the assessee that deferred revenue expenditure could be allowed by way of  carry forward. There is no provision under the Income-tax Act which provides  for such a method of claiming deferred research and development expenditure.  Moreover, the Assessing Officer has allowed the expenses relatable to the year  under consideration and disallowed only the expenditure not relatable to the  relevant assessment year. It is also not the case of the assessee that the  expenditure is relatable to the year under consideration. Therefore, in our  firm view, the authorities below were justified in disallowing such a claim  made by the assessee. Accordingly, the first question of law is answered  against the assessee and in favour of the Revenue.
        7. As regards the third question of law, the main plank of  the argument of the learned counsel for the assessee is based on the decision  of the Supreme Court in Madras Industrial Investment Corporation Ltd. v. CIT  [1997] 225 ITR 802 (SC). However, we find that the said decision relates to the  issue of discount on debentures and the said decision does not apply to the  facts of the present case. Therefore, in our considered opinion, the third  question of law does not merit consideration.
       For the foregoing reasons, this appeal is dismissed.
       No costs.
