The assessee has challenged imposition of penalty under section 271(1)(c). It was noted that the addition/disallowance made by Revenue on account of deduction claimed under section 10A of the Act is not due to any inaccurate particulars furnished by the assessee but on a purely presumptive basis. Thus, the penalty was accordingly deleted.  (AY. 2006-07, 2008-09, 2009-10)
