World boxing's governing body AIBA have acknowledged that 'unprofessional relationships' between their management and judges undermined the boxing competitions at the Rio Olympics.
But they say a four-month independent review has found no evidence of interference in results of bouts.
"An unwelcome axis of influence and sole decision-making had been created and used by former Senior Management that led to a lack of due process being carried out," said AIBA president Ching-kuo Wu.
"Whilst there is no evidence that this had a direct influence on results in Rio, if best practice is not followed 100% of the time by our officials and R&Js (referees and judges), that is unacceptable."
Ireland's Michael Conlan had called AIBA cheats after his defeat at the games.
