I've been mulling over this and I'm hoping I'm wrong.
From what i can see, the Olympic committees have banned the IBA from regulating Olympics boxing, permanently.
Earlier, the IOC abdicated responsibility for ensuring eligibility to the sporting associations. But they've banned this particular one. So now nobody oversees eligibility in boxing.
The IOC accept paperwork without question in boxing. It says M or F on the passport = good enough for the Olympycs, with regards boxing (where they've banned the safeguarding via the sport association).
Qualifying for the Olympics is, I believe, a matter of being selected by your country. No heats, no eliminations prior.
The IBA still oversees other international events. The 2 individuals concerned are banned, permanently as far as I know, from competing in the female category in the IBA events. But the Olympics allow them to compete.
Banned from international competition except for the Olympics.
I assume the IBA will continue to test future athletes to ensure eligibility. Banning those who fail the tests from IBA supervised events such as the world champs
So we've got a possible scenario where, at some future Olympic games, ALL women's boxing competitors may be banned by the IBA from the women's competition because of chromosomal irregularities. Never boxed internationally. Never competed against each other. Never been heard of before.
It's a bit doomsdayish I know, but it's possible under the current system, isn't it?
