Here is the TRI video review rule, it has worked well for several years now.
Given that the technology allows (video system doesn’t go down, etc), TRI will be instituting a video review process for the elimination rounds of the bracket.
Each Alliance is allowed one challenge/review in the playoffs. The alliance captain will be provided a video review coupon in addition to their timeout coupon.
Video review coupons must be given to the head ref during the same time periods in which timeout coupons are allowed following the match to be reviewed.
Only match-affecting calls and yellow/red cards can be reviewed.
The score or lack-of-score being reviewed must be significant enough to affect the outcome of the match. The Head Referee can choose to not review any call that they do not believe will change the outcome of the match.
Video evidence must be indisputable to change a call. The point is to receive credit for an obviously missed score, not debate further a close call that a referee already used their best judgment on. The Head Referee’s decision is final after a review.
Only the event provided video will be used by the Head Referee during a video review. Referees will not review any other video footage, including camcorders, phones, or tablets not provided by the event.
The Head Referee, at their discretion, may choose to review any ruling throughout the event. Please do not ask for a video review at any time other than giving the referee your alliance’s video review coupon during the playoffs. All other requests will not be granted. We don’t plan on ever having this happen, but we want to provide the best event possible to teams; video review of other situations may allow us to do this.
