Rule of Law:
An agency's enabling statute must explicitly require rulemaking to be conducted "on the record" after a hearing to trigger the formal rulemaking procedures of the Administrative Procedure Act (§§ 556-557). Additionally, an agency's rule is considered "reasonable" if it is rationally supported by evidence in the record and addresses a legitimate regulatory objective, even if it causes short-term disruptions.
Facts:
- For many years, U.S. railroads operated a system where freight cars were used as a single common pool, traveling over various connecting lines to their final destination.
- This practice required rules for returning empty cars to the owning railroad, which were established in a voluntary code by a railroad trade association.
- These voluntary rules were frequently disregarded, causing freight cars to remain off their owner's lines for extended periods.
- The Interstate Commerce Commission (ICC) found that this system created a disincentive for railroads to invest in new freight cars, as they could often use cars owned by other railroads while having limited access to their own.
- This lack of investment led to a chronic nationwide shortage of freight cars, resulting in railroads often being unable to promptly supply cars to shippers.
- To address this long-term shortage, the ICC decided to make two of the voluntary car-service rules mandatory, requiring that unloaded freight cars be returned in the direction of the owning railroad's lines.
Procedural Posture:
- The Interstate Commerce Commission (ICC), after an investigation and notice-and-comment rulemaking process, promulgated two mandatory car service rules.
- Allegheny-Ludlum Steel Corp., along with several other railroads and shippers, filed suit in the U.S. District Court for the Western District of Pennsylvania seeking to enjoin the enforcement of the ICC's rules.
- A three-judge panel of the District Court held that the Commission's order was invalid and enjoined its enforcement.
- The United States, on behalf of the ICC, appealed the District Court's decision directly to the Supreme Court of the United States.

Issue:
Does the Interstate Commerce Commission's promulgation of car service rules, authorized by a statute requiring a 'hearing' but not a determination 'on the record,' violate the formal rulemaking requirements of the Administrative Procedure Act or exceed the Commission's authority to establish 'reasonable' rules under the Esch Car Service Act?
Opinions:
Majority - Mr. Justice Rehnquist
No, the Commission's rules do not violate the Administrative Procedure Act and are a reasonable exercise of its statutory authority. First, the formal rulemaking procedures of the APA, found in §§ 556 and 557, are only triggered when the enabling statute requires a rule to be made 'on the record' after a hearing. The Esch Act requires a 'hearing' but does not include the words 'on the record,' meaning the less stringent, informal notice-and-comment procedures of § 553 apply, which the Commission satisfied. Second, the rules are 'reasonable' under the Esch Act because the standard of judicial review for such legislative rulemaking is highly deferential. The Court does not weigh the evidence or substitute its judgment for the agency's. The Commission's finding of a nationwide car shortage was supported by substantial evidence, and its conclusion that these rules would create an incentive for railroads to acquire more cars was a rational long-term solution to that problem, even if it caused short-term inefficiencies. The choice to prioritize a long-term cure over short-term optimization is a policy judgment within the Commission's authority.
Analysis:
This case is a foundational decision in administrative law that clarifies the threshold for formal versus informal rulemaking under the Administrative Procedure Act. By holding that the phrase 'on the record' (or similar language) is necessary to trigger the trial-like procedures of formal rulemaking, the Court significantly expanded agencies' ability to use the more flexible and efficient notice-and-comment process. This interpretation prevents courts from imposing cumbersome procedural requirements on agencies where Congress has not explicitly done so. The decision reinforces judicial deference to agency expertise in complex regulatory fields and affirms that an agency may adopt rules aimed at solving long-term systemic problems, even at the cost of short-term disruption.
