Earlier quoted context omitted.
As a regular fan of MMA and occasional watcher of boxing, I can't think of a single example of the sports' governing bodies overturning a corrupt result, even in the Olympics. Occasionally judges will be fired later; that's it. PEDs are enforced almost sporadically; I wish they didn't bother. Edit: By corrupt result I meant corrupt or inaccurate judging.

When I said "corrupt result" I meant corrupt judging. Sorry I was unclear.
