Income escaping Assessment

In A.Y 85-86 to 90-91 Exp 'X' was allowed.order made on 23.01.92 also allowed exp 'X'.CIT revised order on 23.12.93 to disallow it.Matter went on to SC which disallowed 'X' on 1.1.2009.

So, what does Sec 148,149,150(1),150(2),263,153 Exp2  have to say about '4/6 A.Y's to be considered ' TO GIVE EFFECT TO THE DIRECTION OF ORDER"?? (which are the 6 A.Y assuming 153 exp2 applies)

Please advise.
