Once, the R&D facility is approved by the competent authority and assessee has complied with the prescribed rules, the A.O. is bound to allow the deductions claimed u/s 35(2AB) of the Act, if he is satisfied that the assessee’s facility is approved by the competent authority. In case the A.O. is having any doubt with regard to the goods manufactured by the assessee or expenditure claimed, the A.O. is bound to refer the matter back to the competent authority through appropriate authority i.e. the Central Board of Direct Taxes (CBDT) and seek clarifications. Thus, it would emerge from above analysis that neither the A.O. nor the board was competent to take any decision of any such controversy relating to report and approval granted by the prescribed authority as it involved expert view or opinion. It was prescribed authority alone which would be competent to take decision with regard to the correctness or otherwise and its order of approval granted in form no.3CL as prescribed u/s 35(2AB) of the Act read with rule 7A of the Income Tax Rules, 1962. In the present case on hand, on perusal of the facts available on record, we find that the A.O. without following the procedure laid down under rules, simply disallowed the expenditure claimed by the assessee by holding that the goods manufactured by the assessee are mere office machines and apparatus listed in Eleventh schedule. Therefore, we are of the view that the A.O. is not correct in disallowing the claim made by the assessee u/s 35(2AB) of the Act
