United World Wrestling (UWW) has approved a new IT system to randomly assign referees to matches during competitions.

The move follows controversial decisions which impacted bouts at the Rio 2016 Olympic Games in August.

Members of the UWW's ruling Bureau approved the IT system, which takes into account "several factors" before officials are assigned.

These include current nationality, nation of origin and rating.

A test version of the system was trialed at the UWW Wrestling World Championships for Non-Olympic Weights held in Hungary's capital Budapest this month.

A new referee-education course has also been approved by the Bureau, which will be overseen by the Development Department.

The head of referees and the Referee Commission will now report to the UWW Sport Department, while the position of "supervisor" has been removed.

This leaves just the referee delegate and the mat chairman to form the jury for any challenges.

At Rio 2016, UWW suspended judges Temo Kazarashvilli of Georgia, Tong-Kun Chung of South Korea and Russia's Sergei Novakoskiy for "suspicious officiating".

It came after Uzbekistan's Ikhtiyor Navruzov's quarter-final with Puerto Rico's Franklin Gomez in the men's 65 kilogram division.

There was then further controversy involving Navruzov when he beat Mongolia's Ganzorigiin Mandakhnaran in a bronze medal bout.

Mongolian coaches Tserenbaatar Tsogbayar and Byambarinchen Bayaraa removed their clothes in protest at the result and claimed the judges had "supported" the Uzbek.

"This was a protest, there was a problem with the refereeing," Bayaraa said at the time of the incident. 

"The Mongolian wrestler won 7-6 and he lost because of this [the judges' decision]."

In September, both coaches were banned for three years after being found guilty of "impropriety and assault" and "acts against the reputation and interests of United World Wrestling".

Mongolia's national wrestling federation was fined CHF50,000 (£40,000/$51,000/€46,000), although the country's wrestlers were cleared to compete at future competitions. 

Earlier in September, UWW announced financial support to improve the standard of refereeing.
