Supreme Court of the United States May 31, 1988, 87-363 (Federal Energy Regulatory Commission v. Martin Exploration Management Co.)

Justice Brennan

delivered the opinion of the Court.

These cases involve natural gas covered by overlapping provisions of the Natural Gas Policy Act of 1978 — one setting a price ceiling, the other declaring prices deregulated. Petitioners contend that under § 101(b)(5) of the Act such gas should be classified as deregulated gas.
