In the wake of the TIA's decision to uphold Noriyuki Haga's ban and loss of points following his drugs test failures at Kyalami and Monza, Yamaha have taken their appeal to the Court of Arbitration for Sport (CAS).

This latest twist in the on-going saga will allow Haga to race at Laguna Seca this weekend, a bonus for the rider and fans alike who now get to see one of the most spectacular riders in the world on one of the most spectacular tracks in the world. Haga is known to love Laguna Seca and won at the Californian track in 1998.

Yamaha's original appeal fell on deaf ears when the TIA announced that their appeal had 'not been well founded'. This was a tremendous blow to Haga who has kept himself in the title picture despite the constant dark clouds hanging over his head. If the 45 points that he was stripped of in South Africa were returned to him, he would currently be leading the World Championship.

Yamaha must be careful over the timing of the announcement as it is possible that it could do more harm than good. The TIA reduced Haga's one month ban to three weeks, meaning that Noriyuki would only have missed the Laguna Seca round of the World Superbike Series. However if the CAS announce their decision toward the end of the season when there are races at Assen and Oschersleben on consecutive weekends, Haga may face missing more than one race.
