Casey Martin, a professional golfer with a circulatory disorder, qualified for the PGA Tour in 2000, and then filed suit against the PGA for not allowing him to use a golf cart to ride between holes on the tour. The case went to the US Supreme Court, where the considered whether the ADA protects access to professional golf tournaments by players and whether a competitor with a disability may be denied the use of a golf cart because it would change the "nature of the competition fundamentally."
Justice Stevens delivered the opinion of the Supreme Court, stating that he could use the cart.
How many of you have either heard of Casey Martin tearing up the tour lately, challenging Tiger Woods for the greatest golfer of the 21st Century, or have seen an influx of golfers undergoing self-inflicted injuries, disabilities, or diseases to gain the "advantage" that the "golf purists" claimed would come with this slippery slope decision.
Oscar Pistorius will make a splash, go away, and we will probably never see another case like this in track and field.
