In recent years, with the acceleration of technology growth, teams have been given the opportunity, if they wish, to make sure the decisions of the judge are correct. These rules are not yet strictly regulated anywhere and there are different approaches in different countries. The best option is still being sought.
At the start of the 2014-15 season, this was the rule. Each team has two views in each set. If the review showed that the referee made a mistake, he remains in force, no – the team “burns out” the right to one viewing. “Two burnings” were “burned” – one would not have to pick and hear the judge, yet he was right at least twice.
