Court held that (i) that the Tribunal was not right in holding that the unutilised Modvat credit amounts of earlier years adjusted in the assessment year 1999-2000, could be treated as actual payment of excise duty under section 43B .(ii) That the sales tax paid on raw material in the preceding assessment year was rightly allowed as a deduction in the current assessment year under section 43B .(iii) That the customs duty paid on imports, claimed as a deduction under section 43B , was directly paid by the assessee to the customs authorities during the assessment year in question. The Tribunal had rightly allowed the deduction.( ITA No .250 of 2005 dt. 7-07-2017 ( AY.1999-2000)
