Week in Review at a Glance

US News: Supreme Court Opens Term With Boulder Climate Case

Verified facts

• On Monday, Oct. 5, the Supreme Court heard arguments in Suncor Energy (U.S.A.) Inc. v. County Commissioners of Boulder County, a 2018 lawsuit in which Boulder alleges ExxonMobil and Suncor misled the public about the dangers of fossil fuels (Colorado Public Radio).
• The question is whether federal law, including the Clean Air Act, blocks state-law claims seeking damages for local climate effects. The justices also pressed whether the case is ripe, since no trial has taken place.
• Justice Samuel Alito is recused, so only eight justices will decide the case. A 4–4 split would leave the Colorado Supreme Court’s ruling in place. A decision is expected in the coming months.

Context

According to CPR’s account of the argument, several conservative justices appeared receptive to the oil companies’ position, while Justice Ketanji Brown Jackson suggested review may be premature. A broad ruling could affect more than two dozen similar suits nationwide. Background: Supreme Court’s New Term Opens With Boulder Climate Case.
