In Seven County Infrastructure Coalition v. Eagle County, Colorado, the Supreme Court held that under the National Environmental Policy Act (NEPA), an agency evaluating a particular project is not required to consider the effects of other future or geographically separate projects that may be built or expanded if the proposed project were approved, thus closing the door to the expansive NEPA analyses demanded by project opponents in many cases. The Court also separately stressed that the “central principle of judicial review in NEPA cases is deference,” underscoring that NEPA grants agencies discretion to determine the scope of the review and that their discretionary decisions should not be extensively second-guessed by a court. The cumulative impact of these holdings are much more than a minor course correction and should both significantly limit the scope of future NEPA analyzes and strengthen the defensibility of such analyzes in court.
