Conn. Gen. Stat. § 4-278

(b) The Attorney General may withdraw such action notwithstanding the objections of the person bringing the action if the Attorney General has notified such person of the filing of the motion and the court has provided such person with an opportunity for a hearing on the motion.

(c) The Attorney General may settle the action with the defendant notwithstanding the objections of the person bringing the action if the court determines, after a hearing, that the proposed settlement is fair, adequate and reasonable under all the circumstances. Upon a showing of good cause, such hearing may be held in camera.

(d) Upon a showing by (1) the Attorney General that unrestricted participation during the course of the litigation by the person bringing the action would (A) interfere with or unduly delay the Attorney General's prosecution of the case, or (B) be repetitious, irrelevant or for purposes of harassment; or (2) the defendant that unrestricted participation during the course of the litigation by the person bringing the action would be for purposes of harassment, or would cause the defendant undue burden or unnecessary expense, the court may, in its discretion, impose limitations on the person's participation, including, but not limited to, (i) limiting the number of witnesses that such person may call, (ii) limiting the length of the testimony of any such witnesses, (iii) limiting the person's cross-examination of any such witnesses, or (iv) otherwise limiting the participation by the person in the litigation.

(e) If the court awards civil penalties or damages to the state or if the Attorney General settles with the defendant and receives civil penalties or damages, the person bringing such action shall receive from the proceeds not less than fifteen per cent but not more than twenty-five per cent of such proceeds of the action or settlement of the claim, based upon the extent to which the person substantially contributed to the prosecution of the action. Any such person shall also receive an amount for reasonable expenses which the court finds to have been necessarily incurred, plus reasonable attorneys' fees and costs. All such expenses, fees and costs shall be awarded against the defendant.

(f) Notwithstanding the provisions of subsection (e) of this section, where the action is one that the court finds to be based primarily on disclosures of specific information that was not provided by the person bringing the action relating to allegations or transactions (1) in a criminal, civil or administrative hearing, (2) in a report, hearing, audit or investigation conducted by the General Assembly, a committee of the General Assembly, the Auditors of Public Accounts, a state agency or a quasi-public agency, or (3) from the news media, the court may award from such proceeds to the person bringing the action such sums as it considers appropriate, but in no case more than ten per cent of the proceeds, taking into account the significance of the information and the role of the person bringing the action in advancing the case to litigation. Any such person shall also receive an amount for reasonable expenses that the court finds to have been necessarily incurred, plus reasonable attorneys' fees and costs. All such expenses, fees and costs shall be awarded against the defendant.
