A coalition of conservative legal organizations is pressing the Senate Judiciary Committee to investigate whether Supreme Court Justice Elena Kagan violated federal ethics rules by refusing to step aside from a major climate change case heading to the Court next term. The groups argue that Kagan's own published writings have already compromised her ability to serve as a neutral judge in the dispute.
The coalition, which includes the Judicial Crisis Network, sent a letter to Senate Judiciary Committee leaders on Monday urging hearings into Kagan's participation in Suncor Energy v. Boulder County, Fox News Digital reported. The case asks whether Colorado local governments can use state law to hold oil and gas companies financially liable for their alleged contributions to climate change, a question with enormous implications for the energy industry and for the broader wave of climate litigation sweeping through American courts.
At the center of the recusal demand is a foreword Kagan wrote for the Reference Manual on Scientific Evidence, a resource published by the Federal Judicial Center and distributed to federal judges nationwide. In that foreword, Kagan wrote that judges would increasingly confront lawsuits involving "climate science" and encouraged them to use the manual to evaluate scientific evidence.
The manual included a chapter on climate science that Republican lawmakers and a coalition of Republican attorneys general later accused of presenting a one-sided view. The critics said the chapter promoted scientific theories frequently relied upon by state and local governments suing oil and gas companies over climate change. The Federal Judicial Center eventually removed the chapter from the version of the manual it distributed to judges.
That removal is a telling detail. When Congress and state attorneys general from your own party's opposition force a federal agency to yank a chapter for bias, the material was not a neutral primer. It was advocacy dressed up in a lab coat. And Kagan put her name on the cover letter.
Judicial Crisis Network President Carrie Severino framed the issue in blunt terms, as Fox News reported:
"Justice Kagan's conflicts of interest on climate litigation preclude her from serving as the 'neutral arbiter' required by her oath."
Severino went further, describing the manual's climate chapter as "overtly biased" and arguing that Kagan's endorsement amounted to embracing "the partisan ideals and legal theories driving state and local climate lawfare."
The word "lawfare" is not casual rhetoric. It points to a growing concern among conservatives and energy-sector defenders that climate litigation has become a coordinated strategy, using courtrooms to achieve regulatory goals that elected legislatures have declined to impose. If the justice assigned to weigh the legality of that strategy has already endorsed the scientific framework underlying it, the question of impartiality is not hypothetical.
The coalition's letter does not rest solely on the manual foreword. It also flags what it calls a history of inconsistent recusals by Kagan, citing three prior cases. In NFIB v. Sebelius, the landmark Affordable Care Act challenge, Kagan participated despite having served as solicitor general during the Obama administration while the law was being defended. In American Tradition Partnership v. Bullock, she sat on a case revisiting issues related to Citizens United after she had argued against Citizens United as solicitor general.
And in United States v. Briones, the Supreme Court itself later acknowledged that Kagan should have been recused because of her prior involvement while serving in the executive branch. That concession from the Court's own bench is not a minor footnote, it is an institutional admission that Kagan got a recusal call wrong.
The pattern matters because recusal rules exist to protect public confidence in judicial impartiality. When a justice's track record includes at least one case where even the Court acknowledged she should have stepped aside, fresh demands for recusal carry more weight than they otherwise might. Chief Justice Roberts has pushed back on claims the Supreme Court is a political body, but episodes like these make that defense harder to sustain.
The coalition is asking the Senate Judiciary Committee, now under Republican control, to hold hearings and investigate whether Kagan complied with federal ethics law and the Supreme Court's code of conduct. The request carries a pointed political subtext.
During 2023 and 2024, when Democrats controlled the committee, it launched ethics investigations into Justices Clarence Thomas and Samuel Alito. The committee held hearings and authorized subpoenas, though the inquiry did not lead to impeachment proceedings. Democrats treated those investigations as urgent matters of institutional integrity.
The coalition is now asking whether the same standard applies to a liberal justice. If the committee's ethics apparatus was appropriate for Thomas and Alito, it is difficult to argue it should not be turned toward Kagan when the facts raise a comparable question about impartiality. The principle is either universal or it is partisan theater.
Kagan's situation is not identical to the Thomas and Alito inquiries, which centered on undisclosed gifts and travel. But the underlying question, whether a justice's conduct creates the appearance of bias, is the same. And the coalition's argument has a factual anchor that the Thomas and Alito critics sometimes lacked: a published document, in Kagan's own words, endorsing the very framework at issue in the case before her.
Severino pressed the point directly:
"Kagan's implicit judicial endorsement of the manual and her support of climate-lawfare theories are evidence she cannot remain impartial on climate litigation, including the Court's upcoming Suncor case. She must recuse herself immediately."
The letter's timing is notable. Kagan is scheduled to appear alongside Justice Amy Coney Barrett before the House Appropriations Committee on Tuesday to testify on the Supreme Court's proposed fiscal year 2027 budget. That appearance puts Kagan before Congress at the same moment conservative groups are demanding Congress scrutinize her judicial conduct. Whether any lawmakers raise the recusal issue during budget testimony remains to be seen.
The Supreme Court's Public Information Office did not immediately respond to Fox News Digital's request for comment. Kagan herself has not publicly addressed the recusal demand. She is not the only liberal justice whose neutrality has drawn scrutiny in recent terms, but the specificity of the allegations here, a named document, a removed chapter, a pending case, gives the coalition's argument a concrete foundation that generic complaints about judicial bias often lack.
Several questions remain unanswered. The coalition's letter does not specify which federal ethics statutes it believes Kagan violated, at least not in publicly available descriptions of the correspondence. The exact edition of the Reference Manual and the date Kagan wrote her foreword are not identified in current reporting. And it is unclear whether the Senate Judiciary Committee, under its new Republican leadership, intends to act on the request.
The case itself, Suncor Energy v. Boulder County, is expected to be argued before the Supreme Court next term. The stakes extend well beyond Colorado. If local governments can use state tort law to extract damages from energy companies for climate change, the precedent would open the door to a flood of similar suits nationwide. The legal theory underlying those suits is precisely the theory the coalition says Kagan has already endorsed.
For years, progressive leaders have demanded radical reform of the Supreme Court, including proposals to pack the bench with additional justices. Those demands have typically been framed as responses to conservative rulings. But the Kagan recusal controversy illustrates a different kind of institutional problem, one that reform advocates rarely acknowledge.
The issue is not the size of the Court. It is whether individual justices follow the rules that exist. A nine-member Court with justices who recuse themselves properly is more trustworthy than a fifteen-member Court where justices sit on cases they have already prejudged.
Democrats who have pushed to pack the Court argued that structural changes were necessary to restore public trust. But public trust does not require more seats. It requires justices who take their ethical obligations seriously, and a Senate willing to hold them accountable regardless of which president appointed them.
The coalition's letter puts the Republican-controlled Senate Judiciary Committee in a position to demonstrate whether ethics oversight at the Supreme Court is a bipartisan principle or a weapon wielded only against ideological opponents. Democrats set the precedent by investigating Thomas and Alito. If Republicans decline to examine the Kagan question with equal seriousness, they will have surrendered the high ground they claimed during those earlier fights.
Kagan may have a defensible explanation. Perhaps she views the foreword as a generic endorsement of judicial education rather than an embrace of the climate litigation theories the manual promoted. But that argument grows harder to make when the chapter she promoted was so one-sided that the Federal Judicial Center itself pulled it from circulation.
At a minimum, the question deserves an answer, from Kagan, from the Senate, and from anyone who spent the last two years insisting that Supreme Court ethics are too important to ignore. Public scrutiny of justices is not a partisan exercise. It is a basic requirement of self-government.
If the standard for recusal means anything, it has to mean the same thing whether the justice was appointed by a Republican or a Democrat. Right now, the facts are sitting on the table. The only question is whether anyone in the Senate has the nerve to pick them up.
