This situation is the result of IK's overconfidence in himself.
He was advised about Athar M. when his approval summary was present to the President , Arif Alvi. They could have simply reject his nomination as CJ Islamabad HC on the basis of his proven Pro-PMLN stance.
However, IK gave it a green signal thumping on his chest, " Main sb sambhaal loon ga." ... His overconfidence will wipe him out of the power. You'll see.
