Notwithstanding the provisions of sections 4-278 and 4-279, if the court finds that the action was brought by a person who planned and initiated the violation of subsection (a) of section 4-275, upon which violation an action was brought, then the court may reduce the share of the proceeds of the action that the person would otherwise receive under section 4-278 or 4-279, taking into account the role of that person in advancing the case to litigation and any relevant circumstances pertaining to the violation. If a person bringing the action is convicted of criminal conduct arising from his or her role in the violation of subsection (a) of section 4-275, such person shall be dismissed from the civil action and shall not receive any share of the proceeds of the action. Such dismissal shall not prejudice the right of the Attorney General to continue the action.
