March 26, 2007 - International Association of Athletics Federations (IAAF) introduces rule 144.2, which prohibits: (e) Use of any technical device that incorporates springs, wheels or any other element that provides the user with an advantage over another athlete not using such a device.
July 13, 2007 - In Rome, finishes second in the 400m 'B' race against able-bodied athletes. The race is an IAAF test to observe and determine if rule 144.2 (e) is being broken. The results are inconclusive.

The report claims that the prosthetics give Pistorius an advantage over able-bodied competitors, which Pistorius strongly rejects.
