This case presents the issue of whether the “filed rate doctrine,” which requires a motor carrier to collect the rate published in a filed tariff, obliges Primary Steel, Inc. to pay Maislin Industries and U.S., Inc. an amount greater than that which the parties negotiated. The district court affirmed a ruling of the Interstate Commerce Commission finding it unreasonable under 49 U.S.C. § 10701 for Maislin to recover tariff charges higher than those agreed to by the parties.
Maislin Indus. v. Primary Steel,
Maislin brought this action against Primary Steel to recover freight tariff charges in the amount of $187,923.36. Quinn Freight Liners, Inc., a division of Maislin, made 1,081 shipments of steel for Primary Steel over a three year period. Pursuant to 49 U.S.C. § 10761 (1982), Maislin had filed tariffs with the ICC containing rates and charges applicable to the transportation services provided for Primary Steel. Primary Steel and Maislin, however, had negotiated a shipment rate for an amount below the filed tariff rate, with the understanding that Maislin would file the lower negotiated rate with the ICC. Maislin never filed this negotiated rate with the ICC.
Maislin and its divisions later initiated Chapter 11 bankruptcy proceedings, and the alleged undercharges were discovered by an audit agency appointed by the bankruptcy court. The claimed undercharges of $187,923.36 represent the difference between the negotiated rates paid by Primary Steel and the tariff rate filed by Maislin with the ICC.
*402 The district court relied on the doctrine of “primary jurisdiction,” referring to the ICC the questions of whether Maislin’s freight rates and charges were unreasonable and whether Maislin’s practice of assessing and rebilling Primary Steel for tariff rates higher than those originally negotiated by the parties constituted an unreasonable practice in violation of 49 U.S.C. § 10701(a).
The ICC relied upon its earlier decision in
National Indus. Transp. Leagu
e—Peti
tion to Institute Rulemaking on Negotiated Motor Common Carrier Rates, Ex Parte No. MC-177,
Both parties moved before the district court for summary judgment, Primary Steel relying on the ICC decision, and Mais-lin contending that the ICC decision was not binding, but only an advisory opinion, and that its decision was contrary to law. The district court found that the ICC decision resolved a question within its primary jurisdiction because the issue presented required an inquiry into the lawfulness of a carrier’s practice, and that it was appropriate to defer to the special expertise and administrative discretion of the ICC.
See Iowa Beef Processors, Inc. v. Illinois Centr. Gulf R.R. Co.,
The district court recognized that in the past courts have not permitted deviation from the filed rate required under 49 U.S.C. § 10761.
See, e.g., Louisville & Nashville R.R. Co. v. Maxwell,
I.
Maislin first argues that the issue before the district court was not within the ICC’s primary jurisdiction. The issue before the ICC here was whether Maislin’s practice of assessing and rebilling Primary Steel for the filed tariff rate, which is higher than the rate negotiated and paid by Primary Steel, constituted an unreasonable practice in violation of 49 U.S.C. § 10701(a). Maislin contends that this issue is a question of law and within the competence of the judiciary. In its Order of Referral, the district court, citing
Iowa Beef Processors,
We are satisfied that the reasonableness of Maislin’s billing practices is a matter properly within the ICC’s primary jurisdiction. The Supreme Court in
United States v. Western Pac. R.R. Co.,
The Eighth Circuit has not specifically addressed the application of the primary jurisdiction doctrine in a case involving an allegation of unreasonable collection of undercharges. This issue, however, was addressed by the Eleventh Circuit in
Seaboard System R.R. Co. v. United States,
The decision of whether to allow Maislin to collect undercharges directly involves the reasonableness of Maislin’s billing practices. This determination requires the con *404 sideration of the facts and circumstances regarding both the existence of the alleged negotiated rate and the reasonableness of allowing Maislin to collect the undercharges. Such matters involve the special expertise of the ICC. We affirm the district court’s holding that the ICC had primary jurisdiction to determine the reasonableness of Maislin’s billing practices.
II.
The central argument asserted by Maislin is that the filed rate doctrine bars consideration of equitable defenses. Maislin argues that the district court erred in adopting the ICC decision which considered equitable defenses and found that it would be an unreasonable practice in violation of 49 U.S.C. § 10701 for the carrier to recover tariff charges that were higher than the charges previously agreed to by the carrier and the shipper.
Section 10761(a) of the Interstate Commerce Act requires that common carriers collect the rate published in their tariffs. 49 U.S.C. § 10761(a). In the past, a party’s mistake or ignorance of the applicable tariff rate, or even carrier misquotation of the correct tariff rates, was not an excuse for paying less than the tariff rate.
See, e.g., Louisville & Nashville R.R. v. Maxwell,
In
Buckeye Cellulose Corp. v. Louisville & Nashville R.R. Co.,
Maislin argues that the ICC’s interpretation of the filed rate doctrine in
Negotiated Rates
is contrary to law, and that the district court is precluded from applying that interpretation because of prior judicial precedent, which strictly construed section 10761 as requiring the filed rate doctrine.
See, e.g., Maxwell,
Section 10761(a), which mandates the collection of tariff rates, is only part of an overall regulatory scheme administered by the ICC, and there is no provision in the Interstate Commerce Act elevating this section over section 10701, which requires that tariff rates be reasonable. When conflicts between the two provisions arise, “it is not for * * * [courts] to place enforcement of one doctrine above the other.”
In re Tucker Freight Lines,
Our position is supported by similar cases from other circuits involving the filed rate doctrine. In
Seaboard,
The Interstate Commerce Act, as amended, still embodies the policies of nondiscrimination and uniformity. The primary authority to give effect to those policies, though, is reposed in the ICC. * * * The Commission in this case merely refused to allow the, carrier to collect its undercharge when there was no evidence that the carrier intentionally or knowingly undercharged, when waiving the undercharges was unlikely to encourage carriers to indulge in intentional discriminatory rate “misquotations,” and when the shipper relied upon the carrier’s continuing conduct in misleading the shipper as to the applicable rate under a confusing tariff. The Commission did not abolish the requirement of 49 U.S.C. 10761(a) that carriers must charge the tariff rate.
Seaboard,
Also, in
Western Transp. Co.,
it does not follow that the shipper is necessarily without any remedy in a case like this. A tariff provision has to be reasonable. See 49 U.S.C. § 10704(a). If it is not, it violates the statute; and the Commission, either on its own initiative or on complaint, “shall take appropriate action to compel compliance with” the statute. 49 U.S.C. § 11701. If the notation requirement is, as it appears to be, entirely pointless, the Commission can be expected to set aside this part of the tariff * * *. * * * Wilson should have done what Iowa Beef Processors, Inc., another of Western’s customers, did when sued by Western in bankruptcy court on the very tariff in issue on this case — ask for stay of the court proceedings and then ask the Commission to declare the notation requirement unreasonable.
Thus, the district court is required to enforce the tariff provisions of section 10761(a), unless the ICC, upon referral by the district court, determines that a carrier’s billing practices were unreasonable and that to enforce the tariff requirement would be unlawful.
Maislin further argues that the ICC does not have the authority to change its policy concerning the filed rate doctrine as it can point to no specific statutory change in the
*406
Motor Carrier Act of 1980. We are not persuaded. In
American Trucking Ass’n, Inc. v. Atchison Topeka & Santa Fe Ry. Co.,
the Commission, faced with new developments or in light of reconsideration of the relevant facts and its mandate, may alter its past interpretation and overturn past administrative rulings and practice. * * *. Regulatory agencies do not. establish rules of conduct to last forever; they are supposed, within the limits of the law and of fair and prudent administration, to adapt their rules and practices to the Nation’s needs in a volatile, changing economy.
The ICC may therefore alter its past interpretation and we must accept that change if the new interpretation is reasonable.
See Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc.,
The district court adopted the factual findings of the ICC in determining that collection of the undercharges would be an unreasonable practice. The parties do not challenge the ICC’s findings of fact. Mais-lin continually urges that the ICC’s decision was no more than advisory, relying upon language in
Negotiated Rates. See
III.
Maislin’s argument that it is entitled to prejudgment interest computed from the dates of the shipments at issue need not be addressed, as we have affirmed the district court’s determination that Primary Steel is not liable for the amount of undercharges below the filed tariff rate.
Accordingly, we affirm the judgment of the district court.
Notes
. The Honorable John W. Oliver, Senior United States District Judge for the Western District of Missouri.
. 49 U.S.C. § 10701(a) (1982) provides:
A rate (other than a rail rate), classification, rule, or practice related to transportation or service provided by a carrier subject to the jurisdiction of the Interstate Commerce Commission * * * must be reasonable.
49 U.S.C. 10704(a)(1) (1982) further provides:
When the Interstate Commerce Commission, after a full hearing, decides that a rate charged or collected by a carrier for transportation * * * or that a classification, rule, or practice of that carrier, does or will violate this subtitle, the Commission may prescribe the rate (including a maximum or minimum rate, or both), classification, rule, or practice to be followed. The Commission may order the carrier to stop the violation.
. In Negotiated Rates, the ICC addressed the scope of its primary jurisdiction:
[T]he Commission lacks initial jurisdiction to entertain challenges to the reasonableness of motor carrier rates charged in the past, or to order the waiver of undercharges. However, this does not mean that we lack authority to address the question of what rate should have been charged by a carrier (the tariff rate, the negotiated rate or some other rate) if the carrier brings an action for undercharges in district court, 49. U.S.C. §§ 10705(b)(3), 11706, and the court refers the question of whether the collection of undercharges would be an unreasonable practice to us under the doctrine of primary jurisdiction.
. The Motor Carrier Act of 1980 relaxed regulatory requirements and ICC oversight, thereby allowing far more pricing freedom and increasing competition among carriers.
