Supreme Court justices grappled Monday with whether a blue city can make oil companies pay for climate damages — and legal experts are weighing in.
Monday oral arguments for Suncor Energy v. Board of County Commissioners of Boulder County concluded with the Court’s nine justices appearing to be split on the question. In the case, multiple Colorado governments including the City of Boulder argue the companies should pay for alleged local climate harms, while energy companies Suncor and ExxonMobil contend federal law preempts claims involving interstate and global greenhouse gas emissions.
Republican Utah Attorney General Derek Brown told reporters outside the Supreme Court he left the arguments “optimistic,” saying the dispute ultimately comes down to “who gets to decide the policy.”
“It’s an energy tax dressed up in a fraud lawsuit,” Brown said of Boulder’s claims. “That’s ultimately what this is, because the reality is, they’re trying to regulate action that takes place, not just in their own state, but anywhere across the country.”
Republican Alabama Attorney General Steve Marshall likewise said he felt more confident after hearing the justices’ questions, pointing particularly to Justice Brett Kavanaugh.
“We were confident coming in. I feel better having heard, particularly if you listen to Justice Kavanaugh on his line of questioning,” Marshall told the Daily Caller News Foundation. “It makes it abundantly clear that this is not a question for local officials in Boulder, Colorado, to somehow adopt energy policy for our country. But instead, that’s an issue of federal law, and particularly an issue of Congress.”
Marshall cautioned, however, against interpreting individual questions as indications of how a justice might ultimately vote. Asked about Justice Amy Coney Barrett’s pushback on aspects of the companies’ arguments, Marshall said she was “just doing her job as somebody on the court, trying to fully understand specifically what the advocates are advancing.”
“It’s always foolish to try and predict a Supreme Court outcome solely from oral argument, but it seems like several members of the Court appear primed to defer to the state-court action,” Zac Morgan, senior litigation counsel for Washington Legal Foundation, told the DCNF. “That said, Boulder never offered a satisfying answer to the objection raised by both Justices Barrett and Kavanaugh: why is regulating greenhouse gases outside Boulder, Colorado via a state-court action substantively different from doing so via a municipal or state statute, which all agree would conflict with the Constitution.”
President Donald Trump appointed both Kavanaugh and Barrett to the Court, in 2018 and 2020 respectively.
“The arguments today confirmed what we’ve said all along: federal law forecloses these suits several times over,” Michael R. Williams of the West Virginia Attorney General’s Office told the DCNF. “Whichever path the Court takes, we’re confident they all lead to the same conclusion — Boulder can’t proceed.”
“As Justice Kavanaugh suggested, we think it’s ‘crystal clear’ that interstate issues like these must be governed by federal law, not by varying state law in dozens of state courts,” Williams added.
Kavanaugh, appointed by President Donald Trump in 2018, and Justice Elena Kagan, appointed by President Barack Obama in 2010, at one point appeared to exchange remarks and laugh during the argument.
The Supreme Court agreed in February to hear the case and directed the parties to address whether the justices have statutory and constitutional jurisdiction to decide the dispute.
The case has drawn roughly 20 amicus briefs, with environmental organizations and Democratic-led governments backing Boulder while industry and free-speech groups have raised concerns about allowing states to impose liability over global emissions.
Just one week before oral arguments, Justice Samuel Alito, an appointee of President George W. Bush, recused himself, leaving eight justices to consider the dispute. The justice’s absence — which came following scrutiny into his and his wife’s energy investments — raises the possibility of a 4-4 split. An evenly divided Court would leave intact the Colorado Supreme Court’s decision allowing Boulder’s lawsuit to proceed without creating a controlling nationwide precedent.
The dispute has also spilled into Colorado’s statewide elections. Democratic gubernatorial nominee and current Colorado Attorney General Phil Weiser co-led a coalition of Democratic attorneys general urging the Supreme Court to allow Colorado courts to consider Boulder’s claims.
Additionally, Colorado Secretary of State Jena Griswold, the Democratic nominee seeking to succeed Weiser as attorney general, has also backed Boulder’s lawsuit and pledged to pursue climate-related litigation if elected.
The election could therefore shape Colorado’s climate litigation strategy regardless of how the Supreme Court resolves Suncor.
