Lance Armstrong has been given three weeks to appeal a decision by cycling’s governing body to strip him of all the titles he’s won in the past 14 years.

The 41-year-old has been officially informed that his results dating back to Aug. 1, 1998 have been nullified, the Lausanne, Switzerland-based UCI said today. Backdated to Dec. 6, the American has three weeks to appeal.

In August, the U.S. Anti-Doping Agency, or USADA, stripped Armstrong of his seven Tour de France titles and banned him for life for using prohibited substances after he opted not to contest doping charges in arbitration. USADA’s stand was upheld in October by the International Cycling Union, known by the French acronym UCI.

The UCI decision came after USADA released a 202-page summary of its findings on Oct. 10, which stated Armstrong “engaged in serial cheating” throughout his career. Armstrong has denied using performance-enhancing drugs.

International Olympic Committee President Jacques Rogge told reporters Dec. 5 that the IOC wouldn’t take any action on the bronze medal Armstrong won in the individual time trial at the 2000 Sydney Olympics until he’d been notified by the UCI and given the right to appeal.

“It is only after that period that the IOC can legally take action,” Rogge said.
