5 Judges score the fight and the computer picks 3 of their scores randomly to get a decision. A bit weird imo but that is the way they do it now!!
Here is the complete scoring system lifted from the England boxing Website, In order to assist with questions about the scoring system adopted with the AIBA rules in January 2014, Giorgio Brugnoli, Chairman of the England Boxing Championships, Technical Rules and Referees & Judges Committee, has provided extra clarification for judges, quoting the relevant sections of the AIBA Technical Rules. It is important that you note the following: 1) Clickers should no longer be used. 2) Scoring is based on what you, as a judge, see and judgement calls you make based on what is seen. Note page 10 of AIBA Technical Rules that states: 3.13 Each Judge will independently judge the merits of the two (2) Boxers using the scoring system based on the following criteria: 3.13.1 Number of quality blows on target (see below) 3.13.2 Domination of the Bout 3.13.3 Competitiveness 3.13.4 Technique and tactics superiority 3.13.5 Infringement of the rules 3.14 The Judges must apply the following criteria to score a round: 3.14.1 10 vs 9 - Close round 3.14.2 10 vs 8 - Clear winner with dominance 3.14.3 10 vs 7 - Total dominance 3.14.4 10 vs 6 - Overmatched As always, judging a contest is subjective, but ensuring the above factors are used and taken into consideration by a judge, the correct winner will be selected in the opinion of a particular judge. Maximum concentration is required, thus the reason for the ring set-up ensuring the judge is sitting on his/her own with no interruptions. The target area has NOT changed in any way. The boxer’s arms are not (and never have been) a target area. The head front and side along with the front of the torso on, or above, the line of the belt, comprise the target area. If a boxer has a great finish, resulting in a 10 – 8 round, having lost the first two rounds 10 – 9 so a tie occurs, the judge MUST using the above criteria select a winner. Likewise, a 10 – 8 first round followed by two rounds of 9 -10 should not automatically result in the winner of two rounds being declared the winner. ALL of the criteria above must be considered. The criteria above is not in any particular order and each should be considered in arriving at a judge’s decision. The most skilful and technically proficient boxer, who has been most competitive and domineering, who has landed the most quality blows without infringing the rules as detailed above should prevail. The judge, and the judge alone, must decide what he/she deems to be a close round selecting the winner of the round as per the criteria. There is no rule on what is or is not a close round. The number of additional blows landed is only one of the criteria. A boxer may have landed significantly more blows but they may, as an example, have been landed whilst fouling. For a 10-8 round one boxer must show to be a clear winner with dominance within the criteria described. Total dominance should be quite obvious and as for overmatched, ideally either the referee or the coach will have intervened.
Has there been any other sport where there's been so many changes to the rules in the last 30 years,from No headguards and a 20-19 Points scoring to headguards and Computer scoring and boxers having to rest 3 days after a contest unless it's a Championship to going back to no headgear and a scoring system of 10-9 five judges scoring a contest but only 3 judges scores count and boxers can compete every day but only once a day at Championships, also the no headguards rule only applies to seniors who are now called Elite Boxers and Clubs can no longer call themselves an Amateur Boxing Club if they wish to affiliate to Boxing England or Scotland ,Wales or any other Nation
