2. (2) A person may not bring an action under subdivision (c) that is based upon allegations or transactions that are the subject of a civil suit or an administrative civil money penalty proceeding in which the state or political subdivision is already a party.

3. (3)

   1. (A) The court shall dismiss an action or claim under this section, unless opposed by the Attorney General or prosecuting authority of a political subdivision, if substantially the same allegations or transactions as alleged in the action or claim were publicly disclosed in any of the following:

      1. (i) A criminal, civil, or administrative hearing in which the state or prosecuting authority of a political subdivision or their agents are a party.

      1. (i) Prior to a public disclosure under subparagraph (A), has voluntarily disclosed to the state or political subdivision the information on which allegations or transactions in a claim are based.

(e)

1. (1) If the state or political subdivision proceeds with the action, it shall have the primary responsibility for prosecuting the action. The qui tam plaintiff shall have the right to continue as a full party to the action.

2. (2)

   1. (A) The state or political subdivision may seek to dismiss the action for good cause notwithstanding the objections of the qui tam plaintiff if the qui tam plaintiff has been notified by the state or political subdivision of the filing of the motion and the court has provided the qui tam plaintiff with an opportunity to oppose the motion and present evidence at a hearing.
   2. (B) The state or political subdivision may settle the action with the defendant notwithstanding the objections of the qui tam plaintiff if the court determines, after a hearing providing the qui tam plaintiff an opportunity to present evidence, that the proposed settlement is fair, adequate, and reasonable under all of the circumstances.

(f)

1. (1) If the state or political subdivision elects not to proceed, the qui tam plaintiff shall have the same right to conduct the action as the Attorney General or prosecuting authority would have had if it had chosen to proceed under subdivision (c).

2. (2)

   1. (A) Upon timely application, the court shall permit the state or political subdivision to intervene in an action with which it had initially declined to proceed if the interest of the state or political subdivision in recovery of the property or funds involved is not being adequately represented by the qui tam plaintiff.
   2. (B) If the state or political subdivision is allowed to intervene under subparagraph (A), the qui tam plaintiff shall retain principal responsibility for the action and the recovery of the parties shall be determined as if the state or political subdivision had elected not to proceed.

(g)

1. (1)

   1. (A) If the Attorney General initiates an action pursuant to subdivision (a) or assumes control of an action initiated by a prosecuting authority pursuant to subparagraph (A) of paragraph (3) of subdivision (b), the office of the Attorney General shall receive a fixed 33 percent of the proceeds of the action or settlement of the claim, which shall be used to support its ongoing investigation and prosecution of false claims.
   2. (B) If a prosecuting authority initiates and conducts an action pursuant to subdivision (b), the office of the prosecuting authority shall receive a fixed 33 percent of the proceeds of the action or settlement of the claim, which shall be used to support its ongoing investigation and prosecution of false claims.
   3. (C) If a prosecuting authority intervenes in an action initiated by the Attorney General pursuant to paragraph (3) of subdivision (a) or remains a party to an action assumed by the Attorney General pursuant to subparagraph (A) of paragraph (3) of subdivision (b), the court may award the office of the prosecuting authority a portion of the Attorney General’s fixed 33 percent of the recovery under subparagraph (A), taking into account the prosecuting authority’s role in investigating and conducting the action.
2. (2) If the state or political subdivision proceeds with an action brought by a qui tam plaintiff under subdivision (c), the qui tam plaintiff shall, subject to paragraphs (4) and (5), receive at least 15 percent but not more than 33 percent of the proceeds of the action or settlement of the claim, depending upon the extent to which the qui tam plaintiff substantially contributed to the prosecution of the action. When it conducts the action, the Attorney General’s office or the office of the prosecuting authority of the political subdivision shall receive a fixed 33 percent of the proceeds of the action or settlement of the claim, which shall be used to support its ongoing investigation and prosecution of false claims made against the state or political subdivision. When both the Attorney General and a prosecuting authority are involved in a qui tam action pursuant to subparagraph (C) of paragraph (6) of subdivision (c), the court at its discretion may award the prosecuting authority a portion of the Attorney General’s fixed 33 percent of the recovery, taking into account the prosecuting authority’s contribution to investigating and conducting the action.
3. (3) If the state or political subdivision does not proceed with an action under subdivision (c), the qui tam plaintiff shall, subject to paragraphs (4) and (5), receive an amount that the court decides is reasonable for collecting the civil penalty and damages on behalf of the government. The amount shall be not less than 25 percent and not more than 50 percent of the proceeds of the action or settlement and shall be paid out of these proceeds.
4. (4) If the action is one provided for under paragraph (4) of subdivision (d), the present or former employee of the state or political subdivision is not entitled to any minimum guaranteed recovery from the proceeds. The court, however, may award the qui tam plaintiff those sums from the proceeds as it considers appropriate, but in no case more than 33 percent of the proceeds if the state or political subdivision goes forth with the action or 50 percent if the state or political subdivision declines to go forth, taking into account the significance of the information, the role of the qui tam plaintiff in advancing the case to litigation, and the scope of, and response to, the employee’s attempts to report and gain recovery of the falsely claimed funds through official channels.
5. (5) Whether or not the state or political subdivision proceeds with the action, if the court finds that the action was brought by a person who planned and initiated the violation of Section 12651 upon which the action was brought, then the court may, to the extent the court considers appropriate, reduce the share of the proceeds of the action that the person would otherwise receive under this subdivision, taking into account the role of that person in advancing the case to litigation and any relevant circumstances pertaining to the violation. The court, however, shall not award the qui tam plaintiff more than 33 percent of the proceeds if the state or political subdivision goes forth with the action or 50 percent if the state or political subdivision declines to go forth, taking into account the significance of the information, the role of the qui tam plaintiff in advancing the case to litigation, the scope of the person’s involvement in the fraudulent activity, the person’s attempts to avoid or resist the activity, and all other circumstances surrounding the activity.
6. (6) The portion of the recovery not distributed pursuant to paragraphs (1) to (5), inclusive, shall revert to the state if the underlying false claims involved state funds exclusively and to the political subdivision if the underlying false claims involved political subdivision funds exclusively. If the violation involved both state and political subdivision funds, the court shall make an apportionment between the state and political subdivision based on their relative share of the funds falsely claimed.
7. (7) For purposes of this section, “proceeds” include civil penalties as well as double or treble damages as provided in Section 12651.
8. (8) If the state, political subdivision, or the qui tam plaintiff prevails in or settles any action under subdivision (c), the qui tam plaintiff shall receive an amount for reasonable expenses that the court finds to have been necessarily incurred, plus reasonable costs and attorney’s fees. All expenses, costs, and fees shall be awarded against the defendant and under no circumstances shall they be the responsibility of the state or political subdivision.

9. (9)

   1. (A) If the state or political subdivision does not proceed with the action and the qui tam plaintiff conducts the action, the court may award to the defendant its reasonable attorney’s fees and expenses against the party that proceeded with the action if the defendant prevails in the action and the court finds that the claim was clearly frivolous, clearly vexatious, or brought primarily for purposes of harassment.
   2. (B) If the state or political subdivision proceeds with the action, the court may award the defendant its reasonable attorney’s fees and expenses against the state or political subdivision that proceeded with the action if the defendant prevails in the action and the court finds that the claim was clearly frivolous, clearly vexatious, or brought primarily for purposes of harassment.

(i) Upon a showing by the Attorney General or local prosecuting authority that unrestricted participation during the course of the litigation by the person initiating the action would interfere with or unduly delay the Attorney General’s or local prosecuting authority’s prosecution of the case, or would be repetitious, irrelevant, or for purposes of harassment, the court may, in its discretion, impose limitations on the person’s participation, including the following:

1. (1) Limiting the number of witnesses the person may call.
2. (2) Limiting the length of the testimony of the witnesses.
3. (3) Limiting the person’s cross-examination of witnesses.
4. (4) Otherwise limiting the participation by the person in the litigation.
