But, in respect of GP of assessee was more than 9% for AY 2010-11, no addition was made.  PCIT seta side the order. Tribunal held that PCIT was not justified in setting aside assessment order and substituting his opinion for opinion of AO. All documents in support of purchase made were submitted before AO.
