Assessee challenged the levy of interest on ground that since he had paid self-assessment tax along with interest on 19-3-2015, no interest should be charged under sections 234A and 234B beyond said date.  Held that  interest under sections 234A and 234B, being compensatory in nature, could only be levied up to date of self assessment tax paid by assessee along with interest and not to period beyond that date i.e. 19-3-2015.  The Assessing Officer was to be directed to delete excess interest charged by him.  (AY. 2011 -12 )
