Double amputee Oscar Pistorius is taking his ban from able-bodied races to the Court of Arbitration for Sport due to the International Amateur Athletics Federation's refusal to hear an appeal.

"The IAAF told us for the level of appeal we want we might as well go straight to CAS because they won't consider any appeal or second opinions," the South African said.

Pistorius, who holds the Paralympic 100, 200 and 400 metres world records, has competed mostly in able-bodied events in his homeland and twice overseas.

He had hoped to qualify for this year's Beijing Olympics before the IAAF ruled last month his carbon-fibre prosthetics gave him a considerable advantage over able-bodied sprinters and banned him from any sanctioned able-bodied competition.
