Colombia’s Jaime Eduardo Corredor Segura was excluded from participating in any FIG activities and other international events for three months, for favouring his country during the men’s horizontal bar qualification competition.

His punishment followed that of Frenchman Jean-François Blanquino, who was banned for four months after scoring in favour of five French gymnasts during the rings competition at the event in April.

In rhythmic gymnastics, Spain’s Berta Veiga Vila and Portugal’s Catarina Paula Leandro de Susa e Silva were both warned for "unsatisfactory" judging in the ribbon group finals.

Both test events took place at the Rio Olympic Arena with the sanctions following four that were issued at FIG World Championships last year.

Azerbaijan's Yevgeniya Zhidkova was banned for three months after the Rhythmic World Championships in Stuttgart, where another judge was warned, while two more were warned at the 2015 Artistic World Championships in Glasgow.

None of the sanctioned judges will appear at the Rio 2016 Olympics, FIG confirmed, while six other disciplinary cases which were brought led to no action being taken.

"Accuracy in scoring and the integrity of rankings are key priorities for the International Gymnastics Federation," a FIG statement said.

"Following the 2015 World Championships and the Rio Test Events, both qualifiers for gymnastics at the 2016 Olympic Games, the FIG conducted a thorough analysis of the scores awarded by sworn judges in order to ensure that the athletes' results were compatible with the current code of points.

"This analysis once again confirmed the excellent work of the vast majority of the judges on the road to Rio.

"It also highlighted several apparent problems, leading the FIG to initiate a total of 14 proceedings with the Disciplinary Commission over the past few months."

In January, FIG President Bruno Grandi revealed he was "obsessed with justice".

Judging problems are nothing new in his sport, however.

At Athens 2004, American Paul Hamm won gold in the men's all-around competition but only after South Korean bronze-medalist Yang Tae-young was incorrectly given a start value of 9.9 instead of 10.0 by judges in the parallel bars portion of the final.

The 0.1-point discrepancy was enough to drop Yang from top spot into third.

FIG suspended the three judges for the error, but ruled the final results would remain unchanged.

Yang later filed an official appeal seeking to have his score changed and be awarded a gold medal.

The Court of Arbitration for Sport rejected this action, however.

Last October, seven judges who officiated at the 2014 Artistic Gymnastics World Championships in Nanning, China, were issued with warnings and told to “pay closer attention” at future events.

A plan to introduce fully automated scoring has been touted ahead of Tokyo 2020.
