Definition
The Interstate Commerce Commission (ICC) was the first federal regulatory agency in United States history, established by the Interstate Commerce Act of 1887. It was created to regulate railroads operating across state lines and, over time, expanded to oversee other surface transportation carriers including trucking, bus lines, water carriers, and freight forwarders.
The Commission's core function was to ensure that transportation rates charged by railroads and other carriers were just and reasonable, to prohibit rate discrimination among shippers, and to prevent anticompetitive practices such as pooling arrangements and long-haul/short-haul rate disparities. It had authority to investigate complaints, compel testimony and document production, set maximum rates, and issue cease-and-desist orders.
The ICC was abolished by the ICC Termination Act of 1995. Most of its remaining functions were transferred to the Surface Transportation Board, which continues to exercise jurisdiction over railroad rate and service disputes.

Common Confusion
The ICC is sometimes confused with the Federal Trade Commission (FTC) or other New Deal-era regulatory bodies. The ICC predates the New Deal by nearly fifty years and was a product of Gilded Age reform politics, not Depression-era emergency legislation. Its authority was also sector-specific — limited to surface transportation — whereas agencies like the FTC had broader commercial jurisdiction. Researchers should also distinguish the ICC from the Federal Communications Commission (FCC), which regulates interstate communications, not commerce in goods and transportation.

Why It Matters in Research
The ICC's history spans more than a century of federal regulatory development, making it an unusually rich and complicated source for legal researchers. Several navigational points are essential:
**Chronological complexity.** The Commission's authority changed dramatically through successive legislation. The original 1887 Act gave it limited investigatory power with no binding rate-setting authority. The Hepburn Act of 1906 transformed it into a genuine regulatory body with power to set maximum rates. The Mann-Elkins Act of 1910 extended jurisdiction to telephone and telegraph carriers. Researchers citing ICC authority must identify which statutory period governs.
**Jurisdictional scope expansion.** The ICC's jurisdiction grew to include motor carriers (Motor Carrier Act of 1935), water carriers (Transportation Act of 1940), and freight forwarders (Transportation Act of 1942). Historical sources written before these expansions will describe a narrower agency than the mid-twentieth-century ICC actually was.
**Preemption and dormant commerce clause issues.** The ICC's existence as a federal regulatory body was central to the development of preemption doctrine in transportation law. Where Congress had granted the ICC regulatory authority, state rate regulation was displaced. Researchers working on commerce clause problems should trace which activities fell within ICC jurisdiction at the relevant time, as preemption arguments depend on this boundary.
**Agency as historical record.** ICC decisions, annual reports, and hearing transcripts constitute a substantial primary source record for railroad and transportation history. The Commission published formal decisions beginning in the 1880s; these are separately indexed and distinct from federal court reports.
**Post-abolition transition.** The Surface Transportation Board inherited ICC jurisdiction over railroads, pipelines (other than oil), and certain trucking matters in 1996. Researchers working on post-1995 matters should not cite ICC authority as current law, though STB decisions frequently reference and build on ICC precedent.
**Anderson's entry.** The Anderson's entry provides procedural forms — subpoena and hearing notice language — rather than a substantive legal definition, reflecting the ICC's function as an administrative tribunal. This is useful for researchers reconstructing ICC hearing practice but offers no doctrinal analysis.

Historical Dictionary Support
Anderson's Dictionary of Law does not provide a traditional definitional entry for the Interstate Commerce Commission. What Anderson's includes is procedural form language: hearing notices, subpoena text, and officer-certification language associated with ICC proceedings. This tells us something useful — at the time of Anderson's compilation, the ICC was understood primarily as a quasi-judicial administrative body with defined procedural machinery, not merely an investigatory office.
The form language in Anderson's reflects the Commission's early period, when it functioned largely as an investigatory and adjudicative tribunal rather than a rate-setting authority. This aligns with the known history: the original 1887 Act gave the ICC power to investigate and recommend but not to compel compliance. The procedural apparatus Anderson's captures is that of an administrative court with subpoena power, not yet a body with binding rulemaking authority.
Historical legal dictionaries generally underrepresent the ICC's later regulatory significance because the agency's most consequential powers — binding rate authority under Hepburn, motor carrier oversight under the 1935 Act — accumulated after most nineteenth-century and early twentieth-century dictionary compilations were finalized.

Jurisdictional Note
The ICC exercised federal jurisdiction exclusively. By its nature as an interstate regulatory body, it operated under the Commerce Clause and displaced conflicting state regulation within its jurisdictional scope. Intrastate rail rates were not subject to ICC authority, creating a persistent federal-state boundary that generated litigation throughout the agency's existence.
