VILLEPINTE, France — Nearly 17 months ago in New Delhi, Algerian boxer Imane Khelif was disqualified from the International Boxing Association’s world championships three days after she won an early-round bout with Azalia Amineva, a previously unbeaten Russian prospect.

The disqualification meant Amineva’s official record was perfect again.

The IBA said Khelif and fellow boxer Lin Yu-ting of Taiwan had failed “to meet the required necessary eligibility criteria and were found to have competitive advantages over other female competitors.” The governing body claimed the fighters had failed unspecified eligibility tests — the same tests that ignited a massive controversy about gender regulations and perceptions in sports this week as Khelif and Lin compete at the Paris Olympics.
