PARIS — Olympics organizers said Sunday that arbitrary testing imposed on boxers Imane Khelif and Lin Yu-Ting that led to a storm of vitriol misidentifying the women as transgender or men was “so flawed that it’s impossible to engage with it.”

International Olympic Committee spokesman Mark Adams again vigorously defended Khelif of Algeria and Lin of Taiwan, hammering the sport’s now-banned governing body, the International Boxing Association, that claimed the fighters failed unspecified eligibility tests for women’s competition.
