- Jury Regulations
6.1 The "Jury" will consist of all Leaders, together with a Chairman.

Members of the IMO Advisory Board who are not already members of the Jury, members of the Problem Selection Committee and the Chief Coordinator (as defined in Clause 7 below), may also attend meetings of the Jury as observers. Observers may attend meetings of the Jury only with the permission of the Chairman of the Jury, but will not be entitled to speak or vote. However, they may exceptionally speak at the explicit request of the Chairman of the Jury. Deputy Leaders may attend, as observers, meetings of the Jury held after the Contest.

6.8 Any allegation or suspicion of a violation of the Regulations shall be reported to the Chairman of the Jury, who will determine if there is a prima facie, and the necessity to form a committee to investigate further. The committee will report its findings to the Jury, which will decide if a violation has occurred and, if so, what sanction, if any, to apply. Possible sanctions include the disqualification of an individual Contestant or an entire team from the competition. The decision of the Jury will be final.
7.1 Each problem will be allocated a score out of a maximum of seven points.
7.2 Prior to coordination, Contestants' solutions will be assessed by Leaders and Deputy Leaders in accordance with the marking schemes prepared under the direction of the Chief Coordinator and approved by the Jury.
7.3 Each coordination session will involve two Coordinators provided by México and representatives of the relevant country. Two representatives, normally the Leader and Deputy Leader, are permitted to participate actively in any one session. With the approval of the Chief Coordinator, one further representative may be present to observe the coordination process, but cannot take any active part in it.
7.4 The Leader and the designated Coordinators should agree on the scores for each Contestant. These scores will be recorded on official forms and signed by the Leader and the Coordinators. If the Leader and the Coordinators fail to agree on a score for a Contestant, the matter will first be referred to the head Coordinator for that problem. If there is still no agreement, the matter will be referred to the Chief Coordinator. If the Leader and Chief Coordinator then fail to agree on a score, the Chief Coordinator will report the matter to the Jury with a recommendation as to what the score should be. The Jury will then determine the score.
7.5 If, during a coordination session, the designated Coordinators consider that an irregularity may have occurred, they will immediately refer the matter to the Chief Coordinator. Unless he is satisfied that there is no case to answer, he will report the situation to the Chairman of the Jury.
7.6 Solutions for each problem by Mexican Contestants will be coordinated by the Leader and Deputy Leader of the country that submitted the problem, with the assistance of the head Coordinator for that problem if required.
