 At the 2012 Summer Paralympics in London he won gold in the T44 200m, ahead of Oscar Pistorius who was a favorite to win.Immediately after the race Pistorius caused controversy by criticising the blades Oliveira had used, claiming they were too long and artificially increased his stride length, giving him an unfair advantage.Pistorius' complaint was denied at that time by the International Paralympic Committee, which stated all athletes were measured prior to the race by a classifier and all blade lengths were approved for competition.
