PENSACOLA, Fla. — Justin Gatlin wants to be a spokesman for attention deficit disorder, organize youth running camps and give back to his hometown.

All three are in the works, but they’re also on hold while the banned sprinter tries to defend his 100-meter Olympic title in Beijing.

The task could be getting tougher, too.

The International Olympic Committee said Gatlin, whose four-year doping ban recently was upheld by the Court of Arbitration for Sport, is not eligible to compete in the Beijing Games, regardless of any ruling by a federal court judge in Pensacola.

“Should he wish to appeal this CAS decision, he must do so before the Swiss Federal Court,” wrote IOC director of legal affairs Howard Stupp in the letter dated June 23 that was filed with the court.

Nine lawyers from the U.S. Olympic Committee, USA Track & Field and the U.S. Anti-Doping Agency absolutely agreed Monday. They descended upon Pensacola to try to persuade U.S. District Judge Lacey A. Collier that he doesn’t have the authority to override CAS, sport’s highest court.

Last Friday, Collier issued a temporary restraining order that would allow Gatlin to compete in the 100-meter rounds at the U.S. Olympic track and field trials, which begin Friday in Eugene.

Gatlin must finish in the top three of his event to make the U.S. Olympic team.

“I’m not afraid of what anybody thinks or what anybody’s going to say,” Gatlin said. “Half are going to believe, and the other half are not going to believe in what’s going on right now. My focus and determination is to get out there and prove to the world that I am Justin Gatlin.”

Gatlin spent the last month training with his former college coach in Atlanta. He has tried to stay focused on earning a spot in the Summer Games, but it hasn’t been easy, especially since his future has been so uncertain for so long.

But Friday’s victory — even if it was a temporary one — provided a boost for the former Tennessee star.

“It was more of a strengthening tool for me to get back out there,” Gatlin said. “I felt like I had more purpose to be on the track.”

Maybe so, but Gatlin also refused to let himself get too excited. He knows he hasn’t raced in more than two years and would face plenty of competition at trials.

“Obviously I haven’t had any professional races, but I think with the competitiveness I’ve had in my heart and the determination and feeling that I’ve been discriminated against, I think that will make me a worthy competitor out there.”

First, though, he has to get to the trials.

Collier heard hours of arguments from both sides Monday, then broke for the day. No timetable was set for a decision.

Gatlin had sought the court’s relief to compete, contending the punishment for his first doping offense in 2001 — a positive test for amphetamines, a substance that was part of medication he was taking for attention deficit disorder — violated the Americans with Disabilities Act.

“You can dress this up any way you like, but what it really is a motion to vacate the CAS award,” USOC attorney Howard Jacobs argued. “You can’t come here now just because you’re not happy with the result.”

Two weeks ago, CAS upheld a four-year doping ban against the former world 100- and 200-meter champion. Gatlin asked CAS to rescind the 2001 doping violation — his first of two — which he had hoped would reduce his penalty to a two-year ban, allowing him to compete at trials. Gatlin’s second doping offense stems from a positive test at the Kansas Relays in 2006.

If Gatlin is again barred from the trials, it’s not clear whether he will pursue an appeal with the Swiss Federal Court.

“The idea that the result will be any different with a Swiss court trying to interpret American law under the ADA act seems a little problematic,” Gatlin’s attorney, Joe Zarzaur said outside the courthouse. “But certainly that’s something Justin should consider.”

In the meantime, the U.S. Olympic Committee filed Monday to appeal the restraining order allowing Gatlin to run at the Olympic trials to the 11th Circuit court in Atlanta.

“This last stance we’ve taken has probably been the strongest stance we’ve taken,” Gatlin said. “People feel like it’s the most indirect way to come, but it’s been the most positive since 2 1/2 years ago and I’m really feeling good about that.”
