A coalition of watchdog organisations is urging the Senate Judiciary Committee to investigate Supreme Court Justice Samuel Alito over potential ethical breaches linked to his financial interests in the oil industry. With climate-related lawsuits poised to reshape the future of environmental accountability, concerns about Alito’s involvement in cases that could impact his personal investments have reached a boiling point.
Allegations of Ethical Violations
Justice Alito, the only member of the Supreme Court with direct financial stakes in energy companies, is facing scrutiny for his participation in cases that may favour the oil sector. The coalition’s letter, signed by prominent green groups such as the League of Conservation Voters and the Center for Biological Diversity, emphasises that Alito’s inconsistent recusal practices in matters related to oil and gas are undermining public trust in the judiciary.
“His irregular recusal practice in oil and gas industry-related cases is undermining public confidence in the impartiality of the Court,” the letter asserts. The Supreme Court recently agreed to hear a pivotal case involving major oil companies like Suncor Energy and ExxonMobil. This historic decision marks the first time the court will address whether federal law restricts state and local governments from suing fossil fuel companies for their contributions to climate change.
Alito’s Financial Holdings in Question
Alito’s financial disclosures reveal investments ranging from £60,000 to £245,000 in companies such as ConocoPhillips and Phillips 66, alongside significant holdings in a Vanguard fund that includes Exxon as a major player. These financial ties raise serious questions about his ability to remain impartial in cases that could directly influence the fortunes of the oil industry and his own wallet.

“Their holdings alone should compel Justice Alito to recuse himself from the Boulder case and the parallel state climate deception cases,” the watchdog groups argue. They refer to ongoing lawsuits from over 70 state and local governments accusing oil companies of misleading the public regarding their role in the climate crisis. Yet, it remains uncertain whether Alito has divested any of his stock since his last financial disclosure.
In a previous case concerning the fossil fuel industry’s responsibility for damage along the Louisiana coastline, Alito disclosed his stock in ConocoPhillips and subsequently recused himself just days before oral arguments. This pattern of selective recusal raises eyebrows and adds fuel to the fire of ethical concerns surrounding his position.
Ties to Billionaire Donors
Further complicating matters, Alito’s connection to billionaire donor Paul Singer, whose hedge fund owns a substantial stake in Suncor, has also come under scrutiny. ProPublica highlighted Alito’s failure to disclose a private jet trip funded by Singer, defending his decision by claiming it did not warrant disclosure under existing ethics rules.
Critics argue that Alito’s decision to engage with cases involving his financial interests and those of Singer represents a troubling breach of ethical norms. “Alito’s decision to reverse course and participate in granting the companies’ most recent petition—when a finding in favour of the companies could directly and indirectly benefit both himself and his billionaire friend—is an indefensible breach of ethical boundaries,” the watchdog letter states.
The Need for Robust Ethics Standards
In light of these allegations, the Supreme Court’s recent adoption of its first formal ethics code has been met with scepticism. Although the code calls for justices to recuse themselves when their impartiality might reasonably be questioned, it lacks a robust enforcement mechanism and allows justices to make their own determinations about recusal.

“This year, the court has also implemented new software to identify potential conflicts of interest,” explains Hannah Story Brown from the Revolving Door Project. “Yet, given the stakes involved in climate accountability lawsuits, any holdings in oil companies should disqualify justices from weighing in on these cases.”
For many advocates, a blanket refusal to participate in such cases is the only ethical course of action for Alito. “The highest court in the country should uphold the highest standards, not the lowest ones,” says Lisa Graves, director of True North Research.
Why it Matters
The implications of Justice Alito’s financial entanglements extend far beyond the courtroom. As the climate crisis intensifies, the outcomes of lawsuits against big oil will have lasting effects on environmental policy and accountability. If the judiciary lacks the integrity and impartiality to adjudicate these cases free from personal financial interests, the very foundation of democratic justice is at stake. The call for a thorough investigation into Alito’s conduct is not just about one justice; it is a crucial step in preserving the integrity of the judicial system and ensuring that justice prevails in the fight against climate change.
