Association of Surfing Professionals Chief Executive Officer Brodie Carr resigned over the error that led to Kelly Slater being prematurely crowned world champion last week.

The governing body had calculated that Slater’s Nov. 2 third-round win in San Francisco was enough to give him an unassailable lead atop the championship rankings. Two days later, the association said a mistake had been made and that Slater could still be caught.

“The determination of the ASP world title is the most important moment in professional surfing,” Carr said in a statement on the ASP website. “Ultimately, the responsibility for every activity within ASP lies with me. Therefore, I have elected to resign my position as CEO.”

Carr, who was appointed in 2005, will leave Dec. 31. ASP Chairman Richard Grellman will take temporary charge while a replacement is found, the ASP said.

The final event of this year’s elite World Tour, the Billabong Pipe Masters, takes place Dec. 8-20 on Oahu’s North Shore.
