(b) A copy of the complaint and written disclosure of substantially all material evidence and information the person possesses shall be served on the state pursuant to subdivision one of section three hundred seven of the civil practice law and rules. Any complaint filed in a court of the state of New York shall be filed in supreme court in camera, shall remain under seal for at least sixty days, and shall not be served on the defendant until the court so orders. The seal shall not preclude the attorney general, a local government, or the qui tam plaintiff from serving the complaint, any other pleadings, or the written disclosure of substantially all material evidence and information possessed by the person bringing the action, on relevant state or local government agencies, or on law enforcement authorities of the state, a local government, or other jurisdictions, so that the actions may be investigated or prosecuted, except that such seal applies to the agencies or authorities so served to the same extent as the seal applies to other parties in the action. If the allegations in the complaint allege a violation of section one hundred eighty-nine of this article involving damages to a local government, then the attorney general may at any time provide a copy of such complaint and written disclosure to the attorney for such local government; provided, however, that if the allegations in the complaint involve damages only to a city with a population of one million or more, or only to the state and such a city, then the attorney general shall provide such complaint and written disclosure to the corporation counsel of such city within thirty days. The state may elect to supersede or intervene and proceed with the action, or to authorize a local government that may have sustained damages to supersede or intervene, within sixty days after it receives both the complaint and the material evidence and information; provided, however, that if the allegations in the complaint involve damages only to a city with a population of one million or more, then the attorney general may not supersede or intervene in such action without the consent of the corporation counsel of such city. The attorney general shall consult with the office of the medicaid inspector general prior to superseding or intervening in any action related to the medicaid program. The attorney general may, for good cause shown, move the court for extensions of the time during which the complaint remains under seal under this subdivision. Any such motions may be supported by affidavits or other submissions in camera.

(c) Prior to the expiration of the sixty day period or any extensions obtained under paragraph (b) of this subdivision, the attorney general shall notify the court that he or she:

(i) intends to file a complaint against the defendant on behalf of the people of the state of New York or a local government, and thereby be substituted as the plaintiff in the action and convert the action in all respects from a qui tam civil action brought by a private person into a civil enforcement action by the attorney general under subdivision one of this section;

(ii) intends to intervene in such action, as of right, so as to aid and assist the plaintiff in the action; or

(iii) if the action involves damages sustained by a local government, intends to grant the local government permission to: (A) file and serve a complaint against the defendant, and thereby be substituted as the plaintiff in the action and convert the action in all respects from a qui tam civil action brought by a private person into a civil enforcement action by the local government under subdivision one of this section; or (B) intervene in such action, as of right, so as to aid and assist the plaintiff in the action. The attorney general shall provide the local government with a copy of any such notification at the same time the court is notified.

(d) If the state notifies the court that it intends to file a complaint against the defendant and thereby be substituted as the plaintiff in the action, or to permit a local government to do so, such complaint, whether filed separately or as an amendment to the qui tam plaintiff's complaint, must be filed within thirty days after the notification to the court. For statute of limitations purposes, any such complaint filed by the state or a local government shall relate back to the filing date of the complaint of the qui tam plaintiff, to the extent that the cause of action of the state or local government arises out of the conduct, transactions, or occurrences set forth, or attempted to be set forth, in the complaint of the qui tam plaintiff.

(e) If the state notifies the court that it intends to intervene in the action, or to permit a local government to do so, then such motion to intervene, whether filed separately or as an amendment to the qui tam plaintiff's complaint, shall be filed within thirty days after the notification to the court. For statute of limitations purposes, any complaint filed by the state or a local government, whether filed separately or as an amendment to the qui tam plaintiff's complaint, shall relate back to the filing date of the complaint of the qui tam plaintiff, to the extent that the cause of action of the state or local government arises out of the conduct, transactions, or occurrences set forth, or attempted to be set forth, in the complaint of the qui tam plaintiff.

(f) If the state declines to participate in the action or to authorize participation by a local government, the qui tam action may proceed subject to judicial review under this section, the civil practice law and rules, and other applicable law. The qui tam plaintiff shall provide the state or any applicable local government with a copy of any document filed with the court on or about the date it is filed, or any order issued by the court on or about the date it is issued. A qui tam plaintiff shall notify the state or any applicable local government within five business days of any decision, order or verdict resulting in judgment in favor of the state or local government. 3. Time to answer. If the state decides to participate in a qui tam action or to authorize the participation of a local government, the court shall order that the qui tam complaint be unsealed and served at the time of the filing of the complaint or intervention motion by the state or local government. After the complaint is unsealed, or if a complaint is filed by the state or a local government pursuant to subdivision one of this section, the defendant shall be served with the complaint and summons pursuant to article three of the civil practice law and rules. A copy of any complaint which alleges that damages were sustained by a local government shall also be served on such local government. The defendant shall be required to respond to the summons and complaint within the time allotted under rule three hundred twenty of the civil practice law and rules. 4. Related actions. When a person brings a qui tam action under this section, no person other than the attorney general, or a local government attorney acting pursuant to subdivision one of this section or paragraph (b) of subdivision two of this section, may intervene or bring a related civil action based upon the facts underlying the pending action; provided, however, that nothing in this subdivision shall be deemed to deny persons the right, upon leave of court, to file briefs amicus curiae. 5. Rights of the parties of qui tam actions. (a) If the attorney general elects to convert the qui tam civil action into an attorney general enforcement action, then the state shall have the primary responsibility for prosecuting the action. If the attorney general elects to intervene in the qui tam civil action then the state and the person who commenced the action, and any local government which sustained damages and intervenes in the action, shall share primary responsibility for prosecuting the action. If the attorney general elects to permit a local government to convert the action into a civil enforcement action, then the local government shall have primary responsibility for investigating and prosecuting the action. If the action involves damages to a local government but not the state, and the local government intervenes in the qui tam civil action, then the local government and the person who commenced the action shall share primary responsibility for prosecuting the action. Under no circumstances shall the state or a local government be bound by an act of the person bringing the original action. Such person shall have the right to continue as a party to the action, subject to the limitations set forth in paragraph (b) of this subdivision. Under no circumstances shall the state be bound by the act of a local government that intervenes in an action involving damages to the state. If neither the attorney general nor a local government intervenes in the qui tam action then the qui tam plaintiff shall have the responsibility for prosecuting the action, subject to the attorney general's right to intervene at a later date upon a showing of good cause.

(b)(i) The state may move to dismiss the action notwithstanding the objections of the person initiating the action if the person has been served with the motion to dismiss and the court has provided the person with an opportunity to be heard on the motion. If the action involves damages to both the state and a local government, then the state shall consult with such local government before moving to dismiss the action. If the action involves damages sustained by a local government but not the state, then the local government may move to dismiss the action notwithstanding the objections of the person initiating the action if the person has been served with the motion to dismiss and the court has provided the person with an opportunity to be heard on the motion.

(ii) The state or a local government may settle the action with the defendant notwithstanding the objections of the person initiating the action if the court determines, after an opportunity to be heard, that the proposed settlement is fair, adequate, and reasonable with respect to all parties under all the circumstances. Upon a showing of good cause, such opportunity to be heard may be held in camera.

(iii) Upon a showing by the attorney general or a local government that the original plaintiff's unrestricted participation during the course of the litigation would interfere with or unduly delay the prosecution of the case, or would be repetitious or irrelevant, or upon a showing by the defendant that the original qui tam plaintiff's unrestricted participation during the course of the litigation would be for purposes of harassment or would cause the defendant undue burden, the court may, in its discretion, impose limitations on the original plaintiff's participation in the case, such as:

(A) limiting the number of witnesses the person may call;

(B) limiting the length of the testimony of such witnesses;

(C) limiting the person's cross-examination of witnesses; or

(D) otherwise limiting the participation by the person in the litigation.

(c) Notwithstanding any other provision of law, whether or not the attorney general or a local government elects to supersede or intervene in a qui tam civil action, the attorney general and such local government may elect to pursue any remedy available with respect to the criminal or civil prosecution of the presentation of false claims, including any administrative proceeding to determine a civil money penalty or to refer the matter to the office of the medicaid inspector general for medicaid related matters. If any such alternate civil remedy is pursued in another proceeding, the person initiating the action shall have the same rights in such proceeding as such person would have had if the action had continued under this section.

(d) Notwithstanding any other provision of law, whether or not the attorney general elects to supersede or intervene in a qui tam civil action, or to permit a local government to supersede or intervene in the qui tam civil action, upon a showing by the state or local government that certain actions of discovery by the person initiating the action would interfere with the state's or a local government's investigation or prosecution of a criminal or civil matter arising out of the same facts, the court may stay such discovery for a period of not more than sixty days. Such a showing shall be conducted in camera. The court may extend the period of such stay upon a further showing in camera that the state or a local government has pursued the criminal or civil investigation or proceedings with reasonable diligence and any proposed discovery in the civil action will interfere with the ongoing criminal or civil investigation or proceedings. 6. Awards to qui tam plaintiff. (a) If the attorney general elects to convert the qui tam civil action into an attorney general enforcement action, or to permit a local government to convert the action into a civil enforcement action by such local government, or if the attorney general or a local government elects to intervene in the qui tam civil action, then the person or persons who initiated the qui tam civil action collectively shall be entitled to receive between fifteen and twenty-five percent of the proceeds recovered in the action or in settlement of the action. The court shall determine the percentage of the proceeds to which a person commencing a qui tam civil action is entitled, by considering the extent to which the plaintiff substantially contributed to the prosecution of the action. Where the court finds that the action was based primarily on disclosures of specific information (other than information provided by the person bringing the action) relating to allegations or transactions in a criminal, civil or administrative hearing, in a legislative or administrative report, hearing, audit or investigation, or from the news media, the court may award such sums as it considers appropriate, but in no case more than ten percent of the proceeds, taking into account the significance of the information and the role of the person or persons 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, reasonable attorneys' fees, and costs pursuant to article eighty-one of the civil practice law and rules. All such expenses, fees, and costs shall be awarded against the defendant.

(b) If the attorney general or a local government does not elect to intervene or convert the action, and the action is successful, then the person or persons who initiated the qui tam action which obtains proceeds shall be entitled to receive between twenty-five and thirty percent of the proceeds recovered in the action or settlement of the action. The court shall determine the percentage of the proceeds to which a person commencing a qui tam civil action is entitled, by considering the extent to which the plaintiff substantially contributed to the prosecution of the action. Such person shall also receive an amount for reasonable expenses that the court finds to have been necessarily incurred, reasonable attorneys' fees, and costs pursuant to article eighty-one of the civil practice law and rules. All such expenses, fees, and costs shall be awarded against the defendant.

(c) With the exception of a court award of costs, expenses or attorneys' fees, any payment to a person pursuant to this paragraph shall be made from the proceeds.

(d) If the attorney general or a local government does not proceed with the action and the person bringing the action conducts the action, the court may award to the defendant its reasonable attorneys' fees and expenses if the defendant prevails in the action and the court finds that the claim of the person bringing the action was clearly frivolous, clearly vexatious, or brought primarily for purposes of harassment. 7. Costs, expenses, disbursements and attorneys' fees. In any action brought pursuant to this article, the court may award any local government that participates as a party in the action an amount for reasonable expenses which the court finds to have been necessarily incurred, plus reasonable attorneys' fees, plus costs pursuant to article eighty-one of the civil practice law and rules. All such expenses, fees and costs shall be awarded directly against the defendant and shall not be charged from the proceeds, but shall only be awarded if a local government prevails in the action. 8. Exclusion from recovery. If the court finds that the qui tam civil action was brought by a person who planned or initiated the violation of section one hundred eighty-nine of this article 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 which the person would otherwise be entitled to receive under subdivision six of this section, taking into account the role of such person in advancing the case to litigation and any relevant circumstances pertaining to the violation. If the person bringing the qui tam civil action is convicted of criminal conduct arising from his or her role in the violation of section one hundred eighty-nine of this article, that person shall be dismissed from the qui tam 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 supersede or intervene in such action and to civilly prosecute the same on behalf of the state or a local government. 9. Certain actions barred. (a) The court shall dismiss a qui tam action under this article if:

(i) it is based on allegations or transactions which are the subject of a pending civil action or an administrative action in which the state or a local government is already a party;

(ii) the state or local government has reached a binding settlement or other agreement with the person who violated section one hundred eighty-nine of this article resolving the matter and such agreement has been approved in writing by the attorney general, or by the applicable local government attorney; or

(iii) against a member of the legislature, a member of the judiciary, or a senior executive branch official if the action is based on evidence or information known to the state when the action was brought.

(b) The court shall dismiss a qui tam action under this article, unless opposed by the state or an applicable local government, or unless the qui tam plaintiff is an original source of the information, if substantially the same allegations or transactions as alleged in the action were publicly disclosed:

(i) in a state or local government criminal, civil, or administrative hearing in which the state or a local government or its agent is a party;

(ii) in a federal, New York state or New York local government report, hearing, audit, or investigation that is made on the public record or disseminated broadly to the general public; provided that such information shall not be deemed "publicly disclosed" in a report or investigation because it was disclosed or provided pursuant to article six of the public officers law, or under any other federal, state or local law, rule or program enabling the public to request, receive or view documents or information in the possession of public officials or public agencies;

(iii) in the news media, provided that such allegations or transactions are not "publicly disclosed" in the "news media" merely because information of allegations or transactions have been posted on the internet or on a computer network. 10. Liability. Neither the state nor any local government shall be liable for any expenses which any person incurs in bringing a qui tam civil action under this article.
