Quick Summary

Law professor Jonathan Adler’s amicus brief in the upcoming Supreme Court case Suncor Energy v. Boulder County has drawn criticism from Michael Buschbacher, a managing partner at Boyden Gray PLLC. Buschbacher argues that Adler's brief incorrectly supports Boulder County's position on preemption issues related to climate regulation and litigation. The core of the dispute revolves around whether states or municipalities can regulate greenhouse gas emissions produced outside their jurisdictional boundaries, potentially impacting companies worth nearly $28 trillion in putative damages.

Story summary

The Supreme Court opened its new term on Monday by hearing arguments in Suncor Energy v. Boulder County, a landmark case that could determine whether states and local governments can sue oil and gas companies for climate change damages. The case, which began in 2018 when Boulder County sued Exxon Mobil and Suncor Energy, accuses these companies of contributing to climate-related harms through their fossil fuel operations. The lawsuit aims to hold the companies financially responsible for local climate impacts using state tort laws.

If the Supreme Court allows such lawsuits, it could set a precedent for similar cases across the nation, potentially affecting industries that emit carbon and leading to increased costs for consumers due to higher legal liabilities. Conversely, if the court rules against Boulder County, it would limit states' ability to use their courts for addressing national policy issues like climate change through tort law, thereby protecting manufacturers from an expanding patchwork of lawsuits based on complex environmental problems.

🔮 It seems to suggest that the claims made by the petitioners (and their allies) about the potentially catastrophic effects on the oil and gas industry of an adverse ruling in Suncor may have convinced Justice Alito that he needed to recuse, even though he does not own stock in any of the companies that are part of the case.

Narrative

That cuts strongly against Boulder County, since nothing in the Clean Air Act purports to give states any new power to impose their own specific state law on emissions that originate outside their borders, much less authorizes them to do so with the "exceedingly clear language" required if Congress "wishes to significantly alter the balance between federal and state power."

Claims (87 extracted, 18 hedged)

On Monday the Supreme Court will hear oral argument in Suncor Energy v. Boulder County. asserted
Court → hear → County
My amicus brief in Suncor has received a decent amount of attention--but not all of it favorable. asserted
all → receive → it
Perhaps because I have been critical of much climate regulation and litigation, some were surprised that I believe Boulder County has the better of the preemption arguments here. asserted
County → believe → arguments
Michael Buschbacher, Managing Partner of Boyden Gray PLLC, is among those who think I have erred. asserted
I → think → those
Indeed, he thinks that my work actually supports the other side. asserted
work → think → side
I am unconvinced, and will reply in a follow-up post. asserted
I → reply → post
For now, here is what Buschbacher has to say. asserted
has → say → what
* Prof. Adler Filed His Suncor Amicus Brief in Support of the Wrong Party Michael Buschbacher asserted
Adler → file → Buschbacher
The occasion for this guest post is Prof. Adler's recent amicus brief submitted to the U.S. Supreme Court in Suncor v. Boulder County, set to be argued next month.[1] asserted
occasion → submit → County
By some estimates, the litigation campaign of which Suncor is part asserts some $28 trillion in total putative damages against a select group of energy companies—nearly an entire year of American GDP. asserted
Suncor → assert → GDP
The central question in Suncor is whether states and municipalities can apply their own law to regulate the greenhouse-gas emissions of fuel producers and users, not just for emissions within their own borders, but also for emissions anywhere in the world. asserted
states → apply → world
If that sounds a bit out there, that's because it is. asserted
it → sound → ?
So far, even some of the hand-picked state courts that have heard these claims have been slow to bite. uncertain
that → pick → claims
For example, the Maryland Supreme Court earlier this year rejected similar arguments by the City of Baltimore, concluding that its claims about climate change were all preempted by federal law. uncertain
claims → reject → law
Even the pro-climate litigation dissents in that case agreed that Maryland state law could not reach worldwide emissions directly. uncertain
law → agree → emissions
Several other state courts have reached similar conclusions. asserted
courts → reach → conclusions
Prof. Adler's brief falls to the "left" of these decisions. asserted
brief → fall → decisions
But while his brief is offered in support of Boulder County, it also stops well short of the plaintiffs' position that one state or municipality can apply its own law to the rest of the world. asserted
state → offer → world
Although Prof. Adler opens with broad strokes—"Nothing in federal law, let alone the Constitution, preempts state-law claims seeking relief from injuries allegedly caused or exacerbated by petitioners' conduct," Adler Br. at 2—he later adds a very important caveat: perhaps only the law of the source state (that is, the jurisdiction where the emissions took place) can apply, and everything else is precluded. uncertain
everything → open → place
"No home cooking," as he's put it elsewhere. asserted
he → put → it
There are several points in the brief where I think Prof. Adler errs or leaves key information out, but it's the no-home-cooking caveat that I want to focus on. asserted
I → be → that
In my view, the reading of the Clean Air Act he advocates should require him to take the petitioners' side or, at least, to file on behalf of neither party. asserted
he → advocate → party
As I'll explain below, Prof. Adler comes out on the plaintiffs' side here only by misdescribing (or misapprehending) the case that Boulder County has actually pled. asserted
County → explain → that
As Prof. Adler points out, state power over in-state pollution was historically very broad and remains broad today. asserted
power → point → pollution
What happens in Vegas (or anywhere else) doesn't necessarily stay there. asserted
happens → happen → Vegas
So, although in-state pollution can be governed by state law, interstate pollution—that is, pollution that originates in one jurisdiction and ends up having an alleged effect in another—was exclusively controlled by federal law from time immemorial. asserted
that → govern → time
As my colleague Jared Kelson and I explain in our amicus brief for 74 members of the House, application of this principle to interstate air pollution goes back at least to Georgia v. Tennessee Copper Co., 206 U.S. 230 (1907). asserted
application → explain → Co.
Originally, the federal law in question was federal common law—or "general law," as it was often called, in contrast with specific local law. asserted
it → call → law
Erie Railroad Company v. Tompkins did not abrogate this body of law since rules dealing "with air and water in their ambient or interstate aspects," Illinois v. City of Milwaukee, 406 U.S. 91, 103 (1972), are "matters essentially of federal character," United States v. Standard Oil Co. of Cal., 332 U.S. 301, 307 (1947). asserted
Illinois → abrogate → .
However, the governing federal law changed in the 1970s, when Congress enacted the core environmental regulatory statutes we still have today: the Clean Air Act, the Clean Water Act, etc. asserted
we → govern → statutes
These statutes not only displaced federal common law, they also significantly federalized pollution policy, albeit in a novel way. asserted
they → displace → way
Rather than set uniform national command-and-control regulations as the default rule, the Clean Air Act and Clean Water Act mostly imposed a regime somewhat misleadingly described as "cooperative federalism." asserted
Act → set → federalism
Basically, Congress makes an offer the states can't refuse, using funding strings and sanctions to pressure them to regulate stringently enough to meet federal pollution-control targets set by EPA. asserted
states → make → EPA
Prof. Adler spins all this as Congress "preserving" a large amount of state discretion. asserted
Congress → spin → discretion
That's a rosy version of the history as to traditional areas of state territorial sovereignty—the Clean Air Act in particular drove much American industry overseas contrary to state wishes—but in many areas Congress did at least leave states room to choose how to reduce in-state pollution. asserted
Congress → drive → pollution
As Prof. Adler acknowledges, there are some exceptions where Congress took away even traditional in-state regulatory authority when doing so was necessary to avoid a patchwork of inconsistent state regulations over, e.g., motor vehicle emissions. asserted
doing → acknowledge → emissions
But he's right that, generally, Congress did not disturb the pre-existing balance of federal and state power over emissions regulation. asserted
Congress → disturb → regulation
The problem for Boulder County is that under that pre-existing balance, states had no authority to apply their own law to out-of-state air emissions, which had always been governed by federal common law. asserted
which → have → law
That cuts strongly against Boulder County, since nothing in the Clean Air Act purports to give states any new power to impose their own specific state law on emissions that originate outside their borders, much less authorizes them to do so with the "exceedingly clear language" required if Congress "wishes to significantly alter the balance between federal and state power." asserted
Congress → cut → power
Indeed, the various Clean Air Act provisions that expressly address interstate and international air emissions concerns all presuppose the continued existence of traditional territorial limits on governmental authority. asserted
that → address → authority
