It's interesting - in Gymnastics, they're basically saying "Yeah, there was an error, and the officials who made it have been suspended, but the decision stands", while in Equestrian (Team Eventing, I think), when an error was pointed out, the gold medallists (Germany) had their medals rescinded, and the next three teams moved up a spot.
Consistency would be nice.
Hamm will find that for the rest of his life, the "It wasn't a real gold medal" whispers will follow him around... I'd think he'd do far better with a real silver and a reputation as a stand-up guy, than a gold based on a screw-up at the administrative end...
On a related note, now that pseudoephedrine has been removed from the banned substances list, Andreea Raducan is appealing to get her Sydney AA gold back...
