LAUSANNE, Switzerland (AP) — The top court in international sports expects to take four months to rule on Japanese hammer thrower Koji Murofushi's disputed bid to become an International Olympic Committee member.

The Court of Arbitration for Sport says Murofushi and the Japanese Olympic Committee are challenging the IOC's decision to annul his election as an athletes' representative during the London Games.

The IOC board barred Murofushi and taekwondo fighter Chu Mu-yen of Taiwan from accepting their eight-year posts for breaking election rules. Both were punished for using computers to lobby voters; Chu was warned for distributing candy to voters.

CAS says Chu also intends to file an appeal. The court adds that all parties will submit documents and a hearing may take place.

The IOC has delayed filling four athlete member seats during the appeal process.
