The government this week filed its complaint in the False Claims Act case against Lance Armstrong. The US annouced it would be joining the lawsuit, filed by "whistleblower" Floyd Landis, back in February.
The government's complaint is available here.
The second amended complaint submitted by Landis, the "relator", is available here, and his original 2010 complaint here. The Landis complaint, though long the subject of rumor, only became public in January after the seal required in filing FCA whistleblower actions was lifted.
Back in 2010, I identified one issue in the rumored case as being the need to demonstrate a false claim submitted to the government. The government has asserted both false claims and "reverse false claims" to meet that piece of the statute.
Lance's $125 million personal fortune is on the line. In February, I predicted that Armstrong's public pseudo-mea culpa meant he was prepared to settle the FCA case. No sign yet that a settlement has been reached.
