OPINION OF THE COURT
This is an action to enjoin, annul, set aside, and suspend orders of the Interstate Commerce Commission entered by the Commission, Division 2, on April 16, 1971, and by the Commission en banc on September 21, 1971, in proceedings entitled Investigation and Suspension Docket No. 8548, Inspection in Transit, Grain and Grain Products, reported at 339 I. C.C. 364 and
By the reports and orders here assailed, the Commission has found just *367 and reasonable the establishment of tariff provisions applicable throughout the West at the rate of $13.36 per car for the first in-transit inspection services historically provided by the rail carriers under the line-haul rates. The Commission did not require a reduction in the line-haul rates in relation to the reduced service.
The in-transit inspection service with which we are here concerned has reference to the practice of stopping railroad cars loaded with grain and grain products and placing them on railroad track facilities for the purpose of permitting inspection of the contents of the car, awaiting disposition orders from shippers after inspection, and the subsequent movement of the railroad car. The sample or samples tested determine the official grade of the contents of the car for the purpose of establishing its value at market.
This transit service has been historically provided by the rail carriers in the West as part of the line-haul rates. Until 1968, federal law required official federal inspection and sampling. That function was performed by federal officials. That requirement was eliminated by Congress in 1968. 82 Stat. 761, 7 U.S.C. § 71 et seq. The primary purpose of Congress was to effect an increased utilization' of rail cars. In its brief the Commission noted that ear shortages on a nation-wide basis was a grave problem and that “the Commission’s action here represents a determination to employ all rational and lawful means to attempt to alleviate the difficulty.”
After extensive hearings the Commission found that: (1) the proposed charges do not apply in any instance where applicable line-haul rates plus the charge would exceed the maximum reasonable rates set forth in Grain and Grain Products,
The Commission recognized that the Western railroads were not presently assessing a charge in their line-haul rates for the first stop for inspection. The protestants here contend that under these circumstances the railroads could not segregate the inspection service and assign to it a separate charge without presenting substantial evidence that the new aggregate rate, composed of the line-haul plus inspection-transit rates, represent a just and reasonable rate for all of the services.
In its discussion and conclusions, the Commission found that: “A requirement that the reasonableness of the proposed charges cannot be determined without ‘reference to the line-haul rates, the services furnished thereunder, and the cost thereof’ effectively precludes respondents from ever establishing a separate charge for the accessorial first stop for inspection regardless of the need for such a charge. This inability was not present in the cited proceeding (Transit Charges, Southern Territory,
While purporting to “distinguish” the instant decision from its prior decisions, the Commission discovered that which had been known for years: the maximum reasonable rates established in its Docket No. 17000 eases. This discovery suddenly became a “significant distinguishing feature” in its decision here.
There may be facts and circumstances justifying a Commission reversal of its well established rule that whenever a proposal is made for the establishment of an additional charge for a service that has been provided at the line-haul rates, the reasonableness of the proposed charge may not be divorced from the line-haul rates, the services thereunder, and the cost thereof. Transit Charges, Southern Territory,
We recognize that activities and conditions in dynamic fields may dictate that because of later developments prior administrative construction and interpretation of a statute should no longer be binding if it does not achieve general legislative objectives. National Broadcasting Company v. United States,
The Commission here noted that “even though the combined line-haul rate and the proposed charge does not exceed the prescribed maximum level, it is still incumbent on the Commission to determine if the separate charge is reasonable when related to the specific service for which it is to be assessed.” 339 I. C.C. at 388. This, then, was a departure from its prior interpretive decisions.
We hold that the Commission has not adequately explained, for purposes of our review, its departure from prior norms. It has not sufficiently spelled out the legal basis of its decision. The Commission has not repudiated or overruled its prior decisions requiring that a carrier or carriers proposing separate and additional charges for accessorial services previously included within the line-haul rates may only do so if there is substantial evidence that the existing line-haul rates do not adequately cover the entire services. We are not convinced that the instant proceeding can be “distinguished” as the Commission has indicated. It does appear, however, that it has been distinguished by the commission predicated upon the Commission’s own determination of the burden of proof which it will require and impose in variable quantities, at its discretion, on a case-to-case basis.
We do not believe that the findings of the Commission are adequate in relation to our obligations and tasks on review. We recognize, just as the Supreme Court recognized in Secretary of Agriculture v. United States,
supra,
that “the Commission was not precluded from following a procedure fairly adapted to the unique circumstances of this case.”
The matter is remanded to the Commission for further proceedings consistent with this opinion. The proposed charges are suspended and shall be ineffective until and unless otherwise ordered by this Court.
