"It is my duty to accept responsibility for the recent calculation error that resulted in the premature crowning of Kelly Slater's 11th ASP World Title," Carr said in a statement. "The determination of the ASP World Title is the most important moment in professional surfing. Ultimately, the responsibility for every activity within ASP lies with me. Therefore, I have elected to resign my position as CEO."
Carr leaves after replacing then president Wayne "Rabbit" Bartholomew in 2005. Prior to that, Carr was involved with the 2000 Olympic Games in Sydney, Australia.
Carr has been criticized for his handling of certain situations, namely the death of Andy Irons in 2010 and, more recently, the restructuring of the ASP World Tour.
The ASP's annual board meetings were scheduled during the Rip Curl Pro Search in San Francisco, which finished earlier this week with a win by 17-year-old Gabriel Medina.
"The Board of Directors met today and reluctantly accepted the resignation of Brodie Carr," said ASP Board Member Richard Grellman, who will serve as interim executive chairman. "We would like to recognize his valuable contribution over the last six years and wish him every success in the future."
