ICC announced a new rule ahead of the T20 World Cup 2021

Decision Review System (DRS) will be utilised for the first time in an ICC men's T20I tournament when it is made available at the T20 World Cup starting in the not too distant future by the governing body.

There will be a maximum of two audits each innings according to the playing rules announced by the ICC this week for the next T20 World Cup, which begins on October 17 and will be held in the United Arab Emirates and Oman.

There were fewer competent umpires on the job on occasion because of Covid-19, therefore the supervising board had confirmed an additional pointless DRS audit in June of last year for each group in every inning of a match across all configurations. There are now two ineffective requests each inning for white-ball clubs and three in Tests, depending on the format.

In addition, the ICC has decided to increase the number of overs in postponed and rain-interrupted games. The DLS method dictates that each team must bat for at least five overs during the group stages of the T20 World Cup before the final result is determined.

That is the current norm for all T20I matches. However, in the semi-finals and final, each team should bat for at least 10 overs to have an impact on the result, just like the standard in the women's T20 World Cup last year, where it became a significant debate after the main semi-final between England and India was cleaned out in Sydney and the absence of a hold day saw England dispensed with.

The men's T20 World Cup, for example, has never used the DRS since the last time it was held was in 2016, when the audit framework was not in place for T20Is. DRS was first used in the 2018 ICC Women's World T20 Cup in the Caribbean when just one survey was available to teams. Before the Covid-19 epidemic, this same approach was used at the 2020 release of Australia's women T20 World Cup, the ICC's last multi-group event.

Knowing that umpires can make mistakes in dynamic decisions, the DRS has been used since around 2017 in major ICC events like men's Champions Trophy, 50-over World Cup, and World Test Championship, as well as women's ODI and T20 World Cups, an interaction under which the third umpire can be counselled according to a choice of the on-field umpires, via an umpire survey or a player audit.

As long as the ICC's rules and regulations are followed, the use of DRS in all types of international tournaments for people is allowed.
