The PGA Tour, Inc., is a nonprofit entity that sponsors professional golf tournaments. The PGA has adopted a set of rules that apply to its golf tour. One rule requires golfers to walk the golf course during PGAsponsored tournaments. Casey Martin is a talented amateur golfer who won many high school and university golf championships. Martin has been afflicted with Klippel-TrenaunayWeber Syndrome, a degenerative circulatory disorder that obstructs the flow of blood from his right leg to his heart. The disease is progressive and has atrophied his right leg. Walking causes Martin pain, fatigue, and anxiety, with significant risk of hemorrhaging. When Martin turned professional, he qualified for the PGA Tour. He made a request to use a golf cart while playing in PGA tournaments. When the PGA denied his request, Martin sued the PGA for violation of the Americans with Disabilities Act (ADA) for not making reasonable accommodations for his disability. Did the PGA owe a duty of social responsibility to accommodate Martin’s disability? Does the ADA require the PGA Tour, Inc., to accommodate Casey Martin, a disabled professional golfer, by permitting him to use a golf cart while playing in PGA-sponsored golf tournaments? PGA Tour v.
