The U.S. Postal Service is suing Lance Armstrong, seeking a return of $30 million it paid the cyclist from 1996 to 2004 to sponsor his cycling team. The suit claims that Armstrong's admitted blood doping violated the terms of his contract, and therefore the post office wants its money back.
Armstrong's attorney points out that the Postal Service's own analysis has determined that it received more than $100 million in benefits from sponsoring the Armstrong team. It's really hard for the post office to claim damages now, a decade later. But damages or not, the Post Office is suing Armstrong just because they can, essentially to prove that they are first-rate jackasses.
If the Post Office wants to say the contract is void, it seems to me that Armstrong is entitled to an additional $70 million payment under the doctrine of quantum meruit. Her provided the Post Office with $100 million in benefits and they need to pay him $100 million in compensation. They've only paid $30 million of that. The Post Office needs to pay up.
