Rule 12 refers to reviewing previous decisions:
32 In certain specified circumstances, the registrar may decide to review a decision taken by the GMC to conclude a case, issue a warning, or cease consideration of a case on receipt of undertakings.
33 The review may arise as a result of an application by the practitioner, the maker of the allegation or may be on the registrar’s own initiative.
34 A review may only take place if (1) either the decision in questio may be materially flawed; or there is new information which may have led to a different decision and (2) the registrar considers that the review is necessary for the protection of the public; the prevention of injustice to the practitioner; or is otherwise necessary in the public interest. The registrar will not review a decision more than two years after it was made except in exceptional circumstances.
35 When the registrar decides to review a decision, he will seek representations from the practitioner and the maker of the allegation on his decision to review a case, and, where appropriate, disclose to them any new information received. The registrar will carry out any further enquiries that he considers are necessary to enable him to make a decision.
36 Where the registrar concludes that all or part of the original decision was materially flawed or that there is new information which would probably have led to a different decision, and where he considers that to do so is necessary for the protection of the public; or for the prevention of injustice to the practitioner; or otherwise necessary in the public interest, he may decide to replace the original decision with a fresh decision (if one that the registrar is entitled to make); or refer the matter for reconsideration by the case examiners. If the registrar decides that there are no grounds to do so, then the original decision will stand
