The high court's ruling means the company must hand over records to the Massachusetts attorney general for her ongoing investigation

In a win for climate campaigners and Massachusetts' Democratic Attorney General Maura Healey on Monday, the U.S. Supreme Court rejected ExxonMobil's attempt to block Healey's demand for documents related to her state's ongoing investigation into allegations that one of the world's largest oil and gas corporations deceived the public and investors for decades about how fossil fuels drive global warming.

“The public deserves answers from this company about what it knew about the impacts of burning fossil fuels, and when,” Healey said, responding on Twitter to the ruling. This victory, she added, “clears the way for our office to investigate Exxon's conduct toward consumers and investors.”

The news, which followed a Massachusetts Supreme Court ruling against the company in April, was also welcomed by climate activists — including 350.org U.S. communications manager Thanu Yakupitiyage, who thanked Healey “for her vigilant leadership in standing up for people over polluters.”

“Executives at Exxon knew about climate change decades ago, but they chose to lie to the rest of us to line their oily pockets,” Yakupitiyage declared. “Now, it's those who have done the least to cause the problem who are paying the cost of this deception through our lives and livelihoods. In 2019, we'll use all our power to make sure Big Oil pays its fair share for climate destruction.”

Richard Wiles, executive director of the Center for Climate Integrity, celebrated the high court's decision and said that the company's failed attempt to block Healey from obtaining internal records indicates concern over what the documents could mean for legal attempts to take the company to court over its alleged climate deception.

“Exxon's last ditch effort to avoid turning over additional documents to investigators suggests the company has a whole lot more it's still hiding from the public, shareholders, and policymakers,” he noted.

Wiles also posited that “Exxon fears nothing more than the truth these documents will reveal: that they have known for 50 years that their products cause climate change, and ran a massive deception campaign to confuse the public about it, consequences be damned.”

Bill McKibben, co-founder of 350.org, said in response to the ruling on Monday, “This is an important moment.”

As the #ExxonKnew campaign — run by a coalition of groups that aim to hold the company accountable — concluded, “No one is above the law.”

If this isn't #MondayMotivation, we don't know what is. SCOTUS rejects yet another effort by Exxon to conceal what they knew 50 yrs ago: that their products would lead to catastrophic #climatechange.

Despite a series of damning investigative reports in recent years, ExxonMobil has dismissed allegations of deception as “meritless” and continued to battle against probes launched by the attorneys general of Massachusetts and New York as well as the Security and Exchange Commission (SEC), which ended its investigation in August without any further action.

New York's Democratic Attorney General Barbara Underwood, meanwhile, officially filed suit against ExxonMobil October, claiming the oil giant “built a façade to deceive investors into believing that the company was managing the risks of climate change regulation to its business when, in fact, it was intentionally and systematically underestimating or ignoring them, contrary to its public representations.”

As Carroll Muffett, president of the Center for International Environmental Law (CIEL) pointed out in a statement on Monday, “The millions of pages of documents Exxon was compelled to turn over in the New York investigation evidenced widespread malfeasance reaching the highest levels of the company, and they led the New York attorney general to sue the company on multiple counts of securities fraud.”

However, Muffett continued, “the Massachusetts investigation poses an even bigger risk for the company because the pool of Exxon's potential victims includes not only seven million citizens and consumers in Massachusetts, but also untold tens of millions more living in states with nearly identical consumer protection laws.”
