Larry P. v. Riles

Plaintiffs in these consolidated cases challenge the spraying of herbicides on United States Forest Service (USFS) and Bureau of Land Management (BLM) lands. Both cases involve whether research on and disclosure of the potential carcinogenic, teratogenic and mutagenic effects of the herbicides is required under the National Environmental Policy Act of 1969, 42 U.S.C. §§ 4331-4335 (1976) (NEPA).
