ROME — The Court of Arbitration for Sport dismissed an urgent appeal Saturday from French swimmers Amaury Leveaux and Aurore Mongel seeking last-minute approval of their TYR-manufactured bodysuits for the world championships.

"The court has dismissed the request for provisional measures," CAS secretary general Matthieu Reeb told The Associated Press. "We do not have the full reasons yet but we wanted to inform the parties as soon as possible."

Reeb said the case could still be heard eventually, although with traditional swimming events at Foro Italico beginning Sunday, it would have little meaning.

The decision was made individually by CAS president Mino Auletta, an Italian lawyer.

The TYR B8 was rejected by swimming governing body FINA last month, and the American company maintains the 100 percent polyurethane suit is essentially the same as the Jaked 01, which did meet FINA's standards.

On Friday, FINA passed a rule banning bodysuits, although it won't go into effect until after the worlds.
