There are still various technical loopholes which Asif can get through (assuming that the difference of 1.8 is nothing, which I've still seen evidence which defys that)
One is that is the IPL under the ICC's jurisdiction? The Champions League organizers have convinced the ICC that the Champions League has nothing to do with the ICC, and then theres the Stanford games coming up which Digicel have sued over I believe, since they don't get the rights for them.
I'm sure Asif can be banned from the IPL, but can he be banned from world cricket? One thing that could happen is WADA bans him (since I believe they tested the pee pee) from all competitions which are WADA complacent or are signatories of WADA, and the ICC being one, would have to enforce that (as well as PCB I believe)
This would probably lead Asif to going to the ICL, which I doubt drug tests...
