The U.S. Supreme Court agreed to use a Montana case involving a BP Plc unit to consider shielding companies from environmental cleanup lawsuits that go beyond what federal regulators have ordered.

The justices will review a Montana Supreme Court decision that allowed a suit by property owners whose land was contaminated by arsenic discharged decades ago from a copper smelter in the western part of the state. The landowners are suing BP’s Atlantic Richfield, which acquired the smelter’s operator, Anaconda Co., in 1977.
