The assessment order was passed without referring the matter to pass Draft Assessment order . The  assessee challenged the said order before CIT (A). when the appeal was pending before the CIT (A) the Commissioner passed revision order and set aside the original order , with the direction to pass fresh assessment order. Against  the  revision order , the asseee filled an appeal before the Tribunal . Tribunal up held that the revision order . Assessee filed an appeal before the High Court against the revision order affirmed by the Appellate Tribunal . On behalf of the assessee ,it was contended that when the order passed by the AO being void ab-initio or a nullity revision jurisdiction is bad in law . It was argued on behalf of the revenue that the Tribunal was justified in holding that revision is justified as  the assessee has not challenged the original order by filing writ petition . On appeal the Court held that  merely because the assessee has not filed writ petition but challenged in appeal , ratio laid down by various High Courts could not have been ignored by the Tribunal merely observing that these were the decisions in writ petitions instituted  by the assessees . Accordingly the revision order was set aside and consequently the order of the ITAT also set aside .  (Referred Zuari Cement Ltd v.ACIT (AP) (HC) ( WP.No . 5557 of 2012 dt 21 -2 2013 ) , Control Risk India ( P) Ltd v .Dy.CIT ( 2019) 107 taxmann.com 82 ( Delhi) (HC) , International Air Transport Association v Dy .CIT ( 2016) 68 taxmann.com 246 ( Bom) (HC) , PCIT v.
