MCI Telecommunications Corp. v. American Telephone & Telegraph Co.

Background

This dispute involved AT&T, the longtime dominant long-distance phone company, MCI and other nondominant long-distance carriers, and the Federal Communications Commission (FCC). The Communications Act originally required carriers to file publicly available rate schedules (tariffs). Beginning around 1979 the FCC relaxed those rules for many nondominant carriers, sometimes allowing but later briefly prohibiting optional filing. AT&T sued after MCI collected unfiled rates, and lower courts and prior appeals produced conflicting rulings before the 1992 FCC rulemaking that reinstated permissive detariffing.

Reasoning

The Court examined whether the statute’s phrase allowing the FCC to “modify any requirement” authorizes the agency to eliminate the tariff-filing obligation for virtually all nondominant long-distance carriers. The majority said “modify” means a moderate or limited change and that the filing requirement is central to the law’s rate-regulation scheme. Because the FCC’s permissive detariffing removed the core filing requirement for a large share of the market, the Court concluded the agency exceeded its statutory authority and affirmed the Court of Appeals.

Real world impact

The decision prevents the FCC from broadly exempting nondominant long-distance carriers from public tariff filing under the 1934 Act. That preserves the filed-rate framework used for consumer protection and private enforcement in many long-distance services, at least until Congress or new legislation says otherwise.

Dissents or concurrances

Justice Stevens’s dissent (joined by Justices Blackmun and Souter) argued the FCC reasonably interpreted its power, that competition made filing unnecessary for nondominant firms, and that courts should defer to the agency’s technical judgment.
