Well actually, as someone pointed out on Twitter yesterday, their eligibility criteria is pretty clear.
An 'F' on a passport. That's it. That's all it takes to be eligible for female competition.
So actually, all of this discussion and obfuscation about the IBA and the Russians and the tests and the appeals is totally irrelevant. The IOC simple do not care about any of that.
Multiple, verified tests corroborated by the athletes themselves, demonstrating maleness would not matter to IOC criteria. The 'F' is enough for them.
What they're desperately trying to do is distract from that fact.
