Dismissing the appeal of the Revenue the Court held that  the Tribunal had followed its own decision in which it had granted exemption under section 11 to the assessee for the assessment years 2008-09 and 2009-10. Since there was nothing on record that such orders had been set aside or overruled in any manner by the court, the Tribunal had found no reason to interfere with the order of the Commissioner (Appeals). There was no infirmity in the order of the Tribunal granting exemption under section 11 to the assessee for the assessment year 2010-11.(AY.2010-11)
