The International Cricket Council has announced that England and Australia will be handed extra reviews under the controversial Decision Review System during this winter's Ashes series. to trial use of two extra reviews per innings in Test matches.
Following a meeting of the ICC's chief executives committee in Dubai it was agreed that the number of reviews will be topped-up to two after after 80 overs of a Test innings.
At present teams are only permitted a maximum of two reviews per innings.
The new playing condition will be put on trial from October 1, meaning they will be in place for the start of the Ashes, which begin in Brisbane on November 21.
The change comes following an Ashes series in which the DRS came under criticism from both England and Australia.
The ICC were forced to fly out their general manager cricket Geoff Allardice midway through the series to meet both sides after they lodged official complaints about the DRS.
The third umpires' use of the system, as well as perceived anomalies in some of the technology including Hot Spot, were highlighted as problem areas.
The CEC on Wednesday acted on those concerns - and an update on a technology trial conducted during the third Test at Emirates Old Trafford - by agreeing to set up a 'Working Group' to look at ways to better use the system and train umpires.
It also suggested that Real-Time Snickometer - which is currently only used by TV networks covering matches - could be included in the list of DRS technology available to third umpires.
"The CEC reviewed the performance of the Decision Review System (DRS) during the Ashes series and received an update on a technology trial that was conducted during the Old Trafford Test," an ICC statement read.
"The CEC agreed that a Working Group be constituted to consider how the ICC should best use technology in umpire decision-making in the future.
"The considerations of the group will be wide ranging and include a review of the objectives and philosophies of using technology, the technologies, protocols and procedures as well as the role and training of television umpires.
"It was also agreed that a trial will be conducted whereby a team's referrals will be topped-up to two reviews after 80 overs of an innings. This trial will start from 1 October 2013 in all Test matches in which the DRS is used, with the results being monitored and considered by the Working Group."
On the issue of including Snicko, the statement continued: "Noting that most of the contentious decisions relate to faint edges, the performance of the Real-Time Snickometer during the ICC Champions Trophy 2013 and the Ashes, and the potential to use this technology to assist the umpires in making these decisions was discussed.
"An independent assessment of this technology will be conducted before a decision is made on its inclusion in the list of approved DRS technologies."
