[7] In October 2012, the ICC made amendments on lbw protocols, increasing the margin of uncertainty when the ball hits the batsman's pad.
[11] In September 2013, the ICC announced that for a trial period starting in October 2013, a team's referrals would be reset to two after 80 overs in an innings in Test matches.
[12] Starting in November 2014 from Australia's ODI series versus South Africa, the field umpires' communications have also been broadcast to the viewers.
In 2020, the requirement to appoint neutral match officials was temporarily suspended due to the logistical challenges with international travel during the COVID-19 pandemic.
Following from this change, the number of unsuccessful reviews per test innings was raised from 2 to 3 keeping in mind that there may be less experienced umpires on duty at times.
[17] From 1 June 2023, the "soft-signal" requirement for umpires when referring catches was scrapped as they were "unnecessary and at times confusing".
From October 2017, if the on-field decision remains unchanged because the DRS shows "umpire's call", the team will not lose its review.
[47] The implementation of Umpire's Call has been noted in other sports whereby similar issues have arisen in the case of highly-marginal decisions (i.e. not a "clear mistake) which are perceived to be unfairly decided by forensic and technical means.
Under the experiment, a non-match umpire sits in a separate room with a giant monitor and has discretion over which replays to see rather than relying on the broadcaster.
The system was first used in an Ashes Test (where Nigel Llong performed the duties of non-match umpire) and was repeated in a Pakistan-Sri Lanka ODI.
[54] The Decision Review System has generally received positive response from players and coaches since its launch.
Because of its positive response, the ICC has attempted to apply uniform application of DRS in all cricket games around the world, but this has been difficult for some countries to implement.
[59] Pakistani spinner Saeed Ajmal expressed dissatisfaction over the Decision Review System after a semi-final of the 2011 Cricket World Cup against India.
[60] Hawk-Eye officials admitted in December 2014 that their review technology made an error in a decision to give Pakistan opener Shan Masood out in the second Test against New Zealand in Dubai (17-21 November 2014).
At a meeting held at the ICC office in Dubai two weeks later, Hawk-Eye is understood to have conceded to Pakistan captain Misbah-ul-Haq and team manager Moin Khan that the projection used by their technology for the Leg before wicket decision was incorrect.
[63] During an ODI between Australia and South Africa in June 2016, Hawk-Eye's accuracy came under criticism after AB de Villiers was dismissed clean bowled by Josh Hazlewood but subsequent Hawk-Eye trajectory prediction of the same delivery showed that the ball would go over the stumps.
