Who will take part in Landis hearing

With the Floyd Landis arbitration hearing set to begin Monday at Pepperdine University School of Law in Malibu, Calif., here is a look at the main participants in the case:

The accused
Floyd Landis
Landis grew up in a Mennonite family in southeastern Pennsylvania, began competing in mountain-biking races as a teenager and quickly rose to the elite world level. After switching to road racing, he competed for the U.S.-based Mercury team and was signed by the U.S. Postal Service team after the 2001 season. Landis worked as a support rider for Lance Armstrong on three Tour de France-winning teams before jumping to Phonak in late 2004. He was promoted to team leader following Tyler Hamilton's suspension on a doping offense and finished ninth overall at the 2005 Tour. In 2006, Landis swept three important early-season races -- Paris-Nice, the Tour of California and the Tour de Georgia -- before taking the overall victory in the Tour de France, thanks to a remarkable comeback ride in the Alps in Stage 17 and a strong performance in the final individual time trial. His success came crashing down several days later when a positive test result for an abnormal testosterone-to-epitestosterone level from Stage 17 was leaked to the press. After a backup sample confirmed that result, and the presence of synthetic testosterone was allegedly detected in both samples, Landis was suspended from competition and fired by Phonak. He has vigorously contested the test results and has denied ever using performance-enhancing drugs. Landis, 31, lives in Murrieta, Calif., with his wife Amber and stepdaughter Ryan.

The arbitration panel
Patrice M. Brunet
Brunet, the Montreal lawyer who will chair the panel, was selected by the two other arbitrators using a neutral ranking system after they could not agree on a third member. Brunet, a specialist in immigration law, has also served as legal counsel for the International Triathlon Union and as a Canadian Olympic Committee board member. He has been seated on fewer USADA-convened doping arbitration panels than his two colleagues in this case, but he has been selected to resolve disputes in several Canadian cases and also took part in the USADA hearing that resulted in a lifetime competition ban for U.S. track cyclist Tammy Thomas, convicted of a second doping offense for steroid use in 2002. He also sat on panels that upheld sanctions against U.S. archer Mark Hainline and cyclist James Mortenson, both for missed tests.

Christopher L. Campbell
The Bay Area lawyer was a member of the 1980 U.S. Olympic wrestling team that did not compete due to the U.S. boycott. He subsequently retired due to injury. After earning his law degree, Campbell returned to competition and won a bronze medal in freestyle wrestling at the 1992 Barcelona Games at age 37. Campbell won two NCAA championships at the University of Iowa and a world championship in 1981. He is perceived as sympathetic to athletes and has dissented from the majority ruling for conviction in two high-profile cases -- cyclist Tyler Hamilton (2006) and figure skater Kyoko Ina (2002). In the Ina case, which concerned a missed out-of-competition test, Campbell positioned himself as a critic of the system. He wrote that the USADA appeared to be "pursuing their goal with the very same self-destructive motivation of an athlete who intentionally dopes, i.e., win at all cost,'' and termed the agency's behavior "highly questionable."

Richard H. McLaren
A London, Ontario lawyer, author and professor, McLaren's varied practice includes bankruptcy law, and he once sat on an international commission that decided insurance claims by Holocaust survivors and their families. He runs his own company, Innovative Dispute Resolution. McLaren first became involved in sports jurisprudence as a salary arbitrator for the National Hockey League in 1992. Since then, he has been among the busiest arbitrators in North America. McLaren was on panels that heard doping cases brought against tennis players by the ATP, including Petr Korda, Guillermo Coria and Guillermo Canas, and heard non-doping disputes that arose during the 1998 and 2000 Olympic Games. McLaren was on Court of Arbitration for Sport panels that upheld convictions against British slalom skier Alain Baxter, Spanish cross-country skier Johann Muehlegg and Costa Rican swimmer Claudia Poll.

The U.S. Anti-Doping Agency legal team
USADA's general counsel Travis Tygart, who has been the agency's spokesperson since the Landis charges were announced, will not be litigating the case because he is taking on new responsibilities as CEO, a job he assumes formally this fall. Instead, lawyers from the Colorado offices of the Holme, Roberts & Owen firm, USADA's outside counsel and Tygart's former firm, will present the agency's case. The most experienced in the area of sports law, and doping specifically, is partner Richard R. Young, who helped draft the WADA code and has also served as an arbitrator for various sports national governing bodies and heard disputes from two Olympic Games. He has led several high-profile prosecutions of athletes, including the cases involving Hamilton and track stars Tim Montgomery and Chryste Gaines. Matthew S. Barnett's specialties include antitrust, labor, health care and sports law. Also expected to appear are Daniel J. Dunn, whose practice has primarily been in environmental law, and associate Jennifer Sloan.

The Landis legal team
Former U.S. Attorney Maurice Suh is a partner in the Los Angeles office of the Gibson, Dunn & Crutcher firm. He has specialized in complex business litigation, fraud prosecutions, public corruption and official misconduct cases and environmental crime. Suh oversaw the development of homeland security and emergency preparedness departments as Deputy Mayor of Los Angeles. This is his first case involving a doping offense against an athlete. Howard Jacobs has defended numerous prominent U.S. athletes against doping charges, including Montgomery, Hamilton, sprinter Marion Jones and skeleton racer Zach Lund. Jacobs competed in track and field and cross-country at Florida State University and later as a professional triathlete. When he interviewed for a job with a then-fledgling agency called USADA, CEO Terry Madden suggested he look into representing athletes. Jacobs has also handled cases involving endorsement and team selection disputes. He and Tygart graduated several years apart from The Bolles School, a private Jacksonville, Fla., high school known for its swimming program.
