LOS ANGELES — By admitting to Oprah Winfrey that he doped during his professional cycling career, Lance Armstrong potentially opened himself up to a stream of litigation that could lighten his wallet for years.
And then there's the big question: Will his mea culpa result in the reopening of a criminal investigation by the U.S. government?
Some legal experts believe the disillusionment and anger now directed at Armstrong will force the government to re-examine its evidence in light of his admissions, but others say revisiting the criminal case is unlikely.
"There are no formal guidelines on reopening one, and the discretion is left to the prosecutor," said Matthew Levine, a former federal prosecutor and a white-collar defense attorney in New York. "But generally there's a lot of pressure not to reopen, especially where the declination has been made public. It does happen, but it's quite rare."
Last February, federal prosecutors in Los Angeles announced they were dropping their investigation into Armstrong. A federal grand jury heard testimony from the cyclist's former teammates and associates that could have helped prove Armstrong and some of his fellow cyclists violated federal conspiracy, fraud or racketeering charges.
No reason was given for the decision. Thom Mrozek, a spokesman for the U.S. attorney's office, declined comment Friday.
In the portion of his interview with Winfrey that aired Thursday, Armstrong refused to implicate anyone else. Winfrey asked Armstrong if he felt victorious when the government declined to file charges against him.
"It's hard to define victory," Armstrong said. "But I thought I was out of the woods."
Unlike fellow sports superstars such as Barry Bonds and Roger Clemens who faced criminal charges, Armstrong never spoke with federal authorities or testified before Congress, either or which could have led to obstruction or making false statements charges.
Clemens was acquitted last year on six counts that he lied and obstructed Congress when he denied using performance-enhancing drugs. Bonds was found guilty of obstruction of justice in December 2011 and sentenced to 30 days' home detention. His case is under appeal.
Peter Keane, a law professor at Golden Gate University in San Francisco, is convinced the criminal case will be reopened.
Because of a fraud, "he became very famous, very rich," Keane said. "The idea of him getting a pass on it is going to be looked at with a degree of there's a double standard here. It's something (the government) takes very seriously and they want to discourage people from doing it."
If prosecutors try reopening the case, they do face a hurdle, possibly one that hampered the initial investigation. Any charges may have fallen outside the statute of limitations, but some legal observers said there may be some wiggle room.
"On the criminal side, there are certainly timing issues, but I've never met a prosecutor who didn't try to find a creative way around a statute of limitations," said Marc Mukasey, also a former federal prosecutor and New York-based defense attorney.
Most legal experts agree, however, that Armstrong's confession will expose him to various lawsuits. He is worth an estimated $100 million.
