Co. v. United States, 186 U. S. 279, 22 S. Ct. 920, 46 L. Ed. 1164; United States v. Carr, 132 U. S. 644, 10 S. Ct. 182, 33 L. Ed. 483.
Also, generally, in the absence of statute “the United States is not bound by a mistaken construction of an act of Congress made by one of its officials, and may recover money paid pursuant to such construction.” United States v. Gilhnore (C. C.) 189 F. 761, 762; United States v. Barlow, 132 U. S. 271, 10 S. Ct. 77, 80, 33 L. Ed. 346, In the case last cited this ruling is thus qualified:
“If an allowance is founded upon a clear mistake of fact, not a more error of .judgment, and payments are in consequence made, the statute provides that 'the postmaster general shall cause suit to be b] ought to recover- such wrong or fraudulent payment of exeess, with interest,’ which -means that, if such mistake bo established in tho ae ■ tion of tho department, a recovery must follow. *
“It is also true that where the subjects in relation to which the contract of x>ai ties is made aro necessarily of an uncertain and speculative character or value, and that is known to the parties, a mere mistake by them in their estimate of the value is not deemed sufficient to authorize a recovery of tho moneys paid upon the erroneous estimate. If this were a ease of that description, no recovery could he had.”
Walker v. United States (C. C. Ala.) 139 F. 409, held that: “If officers of tho United States are authorized to shape its course of conduct as to a particular transaction, and they have acted within the purview of tlieir authority, their acts or omissions may in a proper ease work an estoppel against I ho government.” Affirmed (C. C. A. 5) 148 F. 1022.
In Ritter v. United States
(C. C. A. 3) 28 F.(2d) 265, 267, this language is found: “The acts or omissions of the officers of tho government, if they he authorized to bind the United States in a particular transaction, will work estoppel against the government, if the officers have acted within the scope of their authority.”
At this timo, as the report of the Commission states, allowances for maintenance! had been based upon a general formula of the railways, disclosed in their reports in re-sponso io the Commission’s order of October 18, 1920', and elsewhere. The formula and factor subsequently adopted by the Commission were not conceived, or at least reported, nntil many months later. The report of the Commission of Junes 8, 192,6, states that its conclusions differed from the railway formula “chiefly in the use of a general equation factor instead of separate factors for each group of maintenance expenditures, in the-disallowance of claims based on so-called inefficiency of labor, the nse of purchase instead of charge-out prices, the use of separate factors for new and scrap materials, and in the treatment of adjustments for differences in amount and nse of property.” It will be remembered that in making- computations for the issue of the certificate of March 1, 19211, tho Commission struck from the claim of the carrier all items considered questionable because not at that time fully considered and determined.
We think that, under the authority lodged in it by the Act of February 26, 1921, the Interstate Commerce Commission, at tho timo the partial certificate in controversy was issued, had full power, in its discretion, to adopt and act upon tho information and data before it respecting computations to be made? in arriving at the definite ascertainment required by the law, and that it did so. The record discloses no mistake, either of fact or law, nor that the Commission exceeded its authority under the remedial statute. It took affirmative action within the scope of its authority, with no' misconception or misconstruction of thoj terms of that statute, and with full knowledge of the existing facts essential to the determination it was called upon to make. No fraud or collusion is, or could be, claimed. Its conclusion, as evidenced by its certificate of March 1, 1921, is deemed to be conclusive.
In United States v. Louisville, 169 U. S. 249, 18 S. Ct. 358, 360, 42 L. Ed. 735; tho claim was that the government officers had made an error in auditing and allowing the amount of refund of taxes to the city of Louisville, under an act of Congress, authorizing and requiring the Secretary of the, Treasury and the Commissioner of Interna! Revenue to “audit and adjust” the city’s claim. Tho amount allowed had been paid. Subsequently Congress passed another act entitling the city to a further refund, tho amount to be determined in like manner. Under this second authorization, the acting-Commissioner undertook to re-examiner tho first claim, reducing it to the extent of $3,-54,8.89, and deducted that sum. from the amount allowed on the second claim. Tho city recovered in the Court of Claims the amount thus deducted. On appeal the Supreme Court said: “We think the judgment of the court of claims is right. By the pay
