5 USC § 504. Costs and fees of parties
(a)(1) An agency that conducts an adversary adjudication shall award, to a prevailing party other than the United States, fees and other expenses incurred by that party in connection with that proceeding, unless the adjudicative officer of the agency finds that the position of the agency was substantially justified or that special circumstances make an award unjust. Whether or not the position of the agency was substantially justified shall be determined on the basis of the administrative record, as a whole, which is made in the adversary adjudication for which fees and other expenses are sought.
(2) A party seeking an award of fees and other expenses shall, within thirty days of a final disposition in the adversary adjudication, submit to the agency an application which shows that the party is a prevailing party and is eligible to receive an award under this section, and the amount sought, including an itemized statement from any attorney, agent, or expert witness representing or appearing in behalf of the party stating the actual time expended and the rate at which fees and other expenses were computed. The party shall also allege that the position of the agency was not substantially justified. When the United States appeals the underlying merits of an adversary adjudication, no decision on an application for fees and other expenses in connection with that adversary adjudication shall be made under this section until a final and unreviewable decision is rendered by the court on the appeal or until the underlying merits of the case have been finally determined pursuant to the appeal.
(3) The adjudicative officer of the agency may reduce the amount to be awarded, or deny an award, to the extent that the party during the course of the proceedings engaged in conduct which unduly and unreasonably protracted the final resolution of the matter in controversy. The decision of the adjudicative officer of the agency under this section shall be made a part of the record containing the final decision of the agency and shall include written findings and conclusions and the reason or basis therefor. The decision of the agency on the application for fees and other expenses shall be the final administrative decision under this section.
(4) If, in an adversary adjudication arising from an agency action to enforce a party's compliance with a statutory or regulatory requirement, the demand by the agency is substantially in excess of the decision of the adjudicative officer and is unreasonable when compared with such decision, under the facts and circumstances of the case, the adjudicative officer shall award to the party the fees and other expenses related to defending against the excessive demand, unless the party has committed a willful violation of law or otherwise acted in bad faith, or special circumstances make an award unjust. Fees and expenses awarded under this paragraph shall be paid only as a consequence of appropriations provided in advance.
(b)(1) For the purposes of this section—
(A) “fees and other expenses” includes the reasonable expenses of expert witnesses, the reasonable cost of any study, analysis, engineering report, test, or project which is found by the agency to be necessary for the preparation of the party's case, and reasonable attorney or agent fees (The amount of fees awarded under this section shall be based upon prevailing market rates for the kind and quality of the services furnished, except that (i) no expert witness shall be compensated at a rate in excess of the highest rate of compensation for expert witnesses paid by the agency involved, and (ii) attorney or agent fees shall not be awarded in excess of $125 per hour unless the agency determines by regulation that an increase in the cost of living or a special factor, such as the limited availability of qualified attorneys or agents for the proceedings involved, justifies a higher fee.);
(B) “party” means a party, as defined in section 551(3) of this title, who is (i) an individual whose net worth did not exceed $2,000,000 at the time the adversary adjudication was initiated, or (ii) any owner of an unincorporated business, or any partnership, corporation, association, unit of local government, or organization, the net worth of which did not exceed $7,000,000 at the time the adversary adjudication was initiated, and which had not more than 500 employees at the time the adversary adjudication was initiated; except that an organization described in section 501(c)(3) of the Internal Revenue Code of 1986 (26 U.S.C. 501(c)(3)) exempt from taxation under section 501(a) of such Code, or a cooperative association as defined in section 15(a) of the Agricultural Marketing Act (12 U.S.C. 1141j(a)), may be a party regardless of the net worth of such organization or cooperative association or for purposes of subsection (a)(4), a small entity as defined in section 601;
(C) “adversary adjudication” means (i) an adjudication under section 554 of this title in which the position of the United States is represented by counsel or otherwise, but excludes an adjudication for the purpose of establishing or fixing a rate or for the purpose of granting or renewing a license, (ii) any appeal of a decision made pursuant to section 7103 of title 41 before an agency board of contract appeals as provided in section 7105 of title 41, (iii) any hearing conducted under chapter 38 of title 31, and (iv) the Religious Freedom Restoration Act of 1993;
(D) “adjudicative officer” means the deciding official, without regard to whether the official is designated as an administrative law judge, a hearing officer or examiner, or otherwise, who presided at the adversary adjudication;
(E) “position of the agency” means, in addition to the position taken by the agency in the adversary adjudication, the action or failure to act by the agency upon which the adversary adjudication is based; except that fees and other expenses may not be awarded to a party for any portion of the adversary adjudication in which the party has unreasonably protracted the proceedings; and
(F) “demand” means the express demand of the agency which led to the adversary adjudication, but does not include a recitation by the agency of the maximum statutory penalty (i) in the administrative complaint, or (ii) elsewhere when accompanied by an express demand for a lesser amount.
(2) Except as otherwise provided in paragraph (1), the definitions provided in section 551 of this title apply to this section.
(c)(1) After consultation with the Chairman of the Administrative Conference of the United States, each agency shall by rule establish uniform procedures for the submission and consideration of applications for an award of fees and other expenses. If a court reviews the underlying decision of the adversary adjudication, an award for fees and other expenses may be made only pursuant to section 2412(d)(3) of title 28, United States Code.
(2) If a party other than the United States is dissatisfied with a determination of fees and other expenses made under subsection (a), that party may, within 30 days after the determination is made, appeal the determination to the court of the United States having jurisdiction to review the merits of the underlying decision of the agency adversary adjudication. The court's determination on any appeal heard under this paragraph shall be based solely on the factual record made before the agency. The court may modify the determination of fees and other expenses only if the court finds that the failure to make an award of fees and other expenses, or the calculation of the amount of the award, was unsupported by substantial evidence.
(d) Fees and other expenses awarded under this subsection shall be paid by any agency over which the party prevails from any funds made available to the agency by appropriation or otherwise.
(e) The Chairman of the Administrative Conference of the United States, after consultation with the Chief Counsel for Advocacy of the Small Business Administration, shall report annually to the Congress on the amount of fees and other expenses awarded during the preceding fiscal year pursuant to this section. The report shall describe the number, nature, and amount of the awards, the claims involved in the controversy, and any other relevant information which may aid the Congress in evaluating the scope and impact of such awards. Each agency shall provide the Chairman with such information as is necessary for the Chairman to comply with the requirements of this subsection.
(f) No award may be made under this section for costs, fees, or other expenses which may be awarded under section 7430 of the Internal Revenue Code of 1986.
