(a) The authority of any federal agency to sue and be sued in its own name shall not be construed to authorize suits against such federal agency on claims which are cognizable under section 1346(b) of this title, and the remedies provided by this title in such cases shall be exclusive.

(b)

(1) The remedy against the United States provided by sections 1346(b) and 2672 of this title for injury or loss of property, or personal injury or death arising or resulting from the negligent or wrongful act or omission of any employee of the Government while acting within the scope of his office or employment is exclusive of any other civil action or proceeding for money damages by reason of the same subject matter against the employee whose act or omission gave rise to the claim or against the estate of such employee. Any other civil action or proceeding for money damages arising out of or relating to the same subject matter against the employee or the employee's estate is precluded without regard to when the act or omission occurred.

(2) Paragraph (1) does not extend or apply to a civil action against an employee of the Government—

(A) which is brought for a violation of the Constitution of the United States, or

(B) which is brought for a violation of a statute of the United States under which such action against an individual is otherwise authorized.

(c) The Attorney General shall defend any civil action or proceeding brought in any court against any employee of the Government or his estate for any such damage or injury. The employee against whom such civil action or proceeding is brought shall deliver within such time after date of service or knowledge of service as determined by the Attorney General, all process served upon him or an attested true copy thereof to his immediate superior or to whomever was designated by the head of his department to receive such papers and such person shall promptly furnish copies of the pleadings and process therein to the United States attorney for the district embracing the place wherein the proceeding is brought, to the Attorney General, and to the head of his employing Federal agency.

(d)

(1) Upon certification by the Attorney General that the defendant employee was acting within the scope of his office or employment at the time of the incident out of which the claim arose, any civil action or proceeding commenced upon such claim in a United States district court shall be deemed an action against the United States under the provisions of this title and all references thereto, and the United States shall be substituted as the party defendant.

(2) Upon certification by the Attorney General that the defendant employee was acting within the scope of his office or employment at the time of the incident out of which the claim arose, any civil action or proceeding commenced upon such claim in a State court shall be removed without bond at any time before trial by the Attorney General to the district court of the United States for the district and division embracing the place in which the action or proceeding is pending. Such action or proceeding shall be deemed to be an action or proceeding brought against the United States under the provisions of this title and all references thereto, and the United States shall be substituted as the party defendant. This certification of the Attorney General shall conclusively establish scope of office or employment for purposes of removal.

(3) In the event that the Attorney General has refused to certify scope of office or employment under this section, the employee may at any time before trial petition the court to find and certify that the employee was acting within the scope of his office or employment. Upon such certification by the court, such action or proceeding shall be deemed to be an action or proceeding brought against the United States under the provisions of this title and all references thereto, and the United States shall be substituted as the party defendant. A copy of the petition shall be served upon the United States in accordance with the provisions of Rule 4(d)(4) ¹ of the Federal Rules of Civil Procedure. In the event the petition is filed in a civil action or proceeding pending in a State court, the action or proceeding may be removed without bond by the Attorney General to the district court of the United States for the district and division embracing the place in which it is pending. If, in considering the petition, the district court determines that the employee was not acting within the scope of his office or employment, the action or proceeding shall be remanded to the State court.

(4) Upon certification, any action or proceeding subject to paragraph (1), (2), or (3) shall proceed in the same manner as any action against the United States filed pursuant to section 1346(b) of this title and shall be subject to the limitations and exceptions applicable to those actions.

(5) Whenever an action or proceeding in which the United States is substituted as the party defendant under this subsection is dismissed for failure first to present a claim pursuant to section 2675(a) of this title, such a claim shall be deemed to be timely presented under section 2401(b) of this title if—

(A) the claim would have been timely had it been filed on the date the underlying civil action was commenced, and

(B) the claim is presented to the appropriate Federal agency within 60 days after dismissal of the civil action.

(e) The Attorney General may compromise or settle any claim asserted in such civil action or proceeding in the manner provided in section 2677, and with the same effect.
