Assessee, in return of income claimed interest income earned on fixed deposit as part of its business income and AO disallowed same on ground that it did not carry out any business during year and passed assessment order under S. 143(3) on 30-3-2014 and subsequently AO issued  reopening notice dated 26-3-2018 on ground that interest income was required to be taxed as income from other sources. On writ the Court held that  notice was issued beyond period of four years from end of assessment year 2011-12 and there had been a complete disclosure of all material facts on part of assessee during regular assessment proceedings under S. 143(3), impugned notice was clearly hit by first proviso to section 147 and deserved to be set aside.  (AY. 2011-12)
