The disabled 21-year-old sprinter, who runs on specially adapted carbon fibre blades after having his legs amputated below the knee, will learn if his appeal to the Court of Arbitration for Sport (CAS) over his Olympic ban has been successful.

"The decision will be published at 1500 local time (1300GMT) on the CAS official website," said a CAS statement released on Thursday.

The appeal was heard on April 29-30.

The International Association of Athletics Federations (IAAF) banned the 400m runner from all competitions involving able-bodied athletes because of claims that the artificial legs he uses give him an unfair advantage.

If he wins his case he still has to achieve the minimum Olympic qualifying time of 45.95sec, or 45.55 if another South African runs less than 45.95. Pistorius' personal record is 46.46.

Pistorius, who as an 11-month-old baby had both of his legs amputated below the knee, runs on specially adapted carbon fibre blades that have seen him win Paralympic titles and challenge the times set by top-level able-bodied athletes.

But a scientific investigation into his springy prosthetics carried out by the Institute of Biomechanics at Cologne University last November found that they gave him a clear competitive edge over such athletes.
