Boxing governing body AIBA has sidelined all 36 referees and judges used at the Rio de Janeiro Olympics.
AIBA is currently investigating the performance of judges after they were embroiled in controversy with allegations some beaten boxers were robbed of victory.
The controversy over the new '10 point must' scoring system is at the heart of the investigation.
"While the majority of the boxing competition in Rio 2016 was received very positively... a small number of decisions under debate indicated that further reforms in the AIBA R&J (referee and judging) procedures were necessary," the International Boxing Association said in a statement.
"Initial decisions were made on-site during Rio 2016 to ensure the smooth running of the rest of the competition. The results of a specific R&J investigation, currently underway, will allow AIBA to fully assess what action needs to be taken.
"In the meantime, it has been decided that all 36 R&Js that were used at the Olympic Games will not officiate at any AIBA event until the investigation reaches its conclusion, along with further immediate measures adopted by the commissions."
AIBA found that "less than a handful" of the decisions from 239 bouts reviewed were not at the level expected prompting some officials to be stood down during the Rio Games.
