Montana’s Supreme Court on Wednesday upheld a landmark climate ruling that said the state was violating residents’ constitutional right to a clean environment by permitting oil, gas and coal projects without regard for global warming.

The justices, in a 6-1 ruling, rejected the state’s argument that greenhouse gases released from Montana fossil fuel projects are minuscule on a global scale and reducing them would have no effect on climate change, likening it to asking: “If everyone else jumped off a bridge, would you do it too?”

The plaintiffs can enforce their environmental rights “without requiring everyone else to stop jumping off bridges or adding fuel to the fire,” Chief Justice Mike McGrath wrote for the majority. “Otherwise the right to a clean and healthful environment is meaningless.”

Only a few other states, including Hawaii, Illinois, Pennsylvania, Massachusetts and New York, have similar environmental protections enshrined in their constitutions.  The lawsuit filed in 2020 by 16 Montanans —who are now ages 7 to 23 — was considered a breakthrough in attempts by young environmentalists and their attorneys to use the courts to leverage action on climate change.

“This ruling is a victory not just for us, but for every young person whose future is threatened by climate change,” lead plaintiff Rikki Held said in a statement Wednesday.

During the 2023 trial in state District Court, the young plaintiffs described how climate change profoundly affects their lives: worsening wildfires foul the air they breathe, while drought and decreased snowpack deplete rivers that sustain farming, fish, wildlife and recreation and affect Native traditions.

Going forward, Montana must “carefully assess the greenhouse gas emissions and climate impacts of all future fossil fuel permits,” said Melissa Hornbein, an attorney with the Western Environmental Law Center and attorney for the plaintiffs.

Republican Gov. Greg Gianforte said the state was still reviewing the decision, but warned of “perpetual lawsuits that will waste taxpayer dollars and drive up energy bills for hardworking Montanans.”

“This decision does nothing more than declare open season on Montana’s all-of-the-above approach to energy,” he said, which promotes using both fossil fuels and renewables.

A day earlier, Gianforte held meetings on how the state can increase energy production, which involved energy suppliers, large energy consumers, public utility companies, transmission stakeholders and legislators.

Incoming Senate President Matt Regier and House Speaker Brandon Ler, both Republicans, joined Gianforte in alleging the justices were overstepping their authority and had strayed into making policy.

“Judicial reform was already a top priority for Republican lawmakers,” Regier and Ler said, warning the justices to “buckle up.”

Montana courts have blocked or overturned numerous laws passed by Republicans in the 2021 and 2023 legislative sessions as being unconstitutional, including laws to limit access to abortion.

In seeking to overturn the District Court ruling, the state had argued the plaintiffs should be required to challenge individual fossil fuel development permits as they’re issued — which would have involved trying to challenge even smaller amounts of emissions.

Carbon dioxide, which is released when fossil fuels are burned, traps heat in the atmosphere and is largely responsible for the warming of the climate. June brought record warm global temperatures for the 13th straight month, according to European climate service Copernicus. The streak ended in July.

Montana’s Constitution requires agencies to “maintain and improve” a clean environment. A law signed by Gianforte last year said environmental reviews may not consider climate impacts unless the federal government makes carbon dioxide a regulated pollutant. The Montana Supreme Court’s ruling found that law to be unconstitutional.

The Supreme Court on Monday rejected an appeal from Martin Shkreli, who was once dubbed “Pharma Bro” after jacking up the price of a lifesaving drug.

Shkreli appealed an order to return $64.6 million in profits he and his former company reaped after monopolizing the market for the medication and drastically increasing its price. His lawyers argued that the money went to his company rather than him personally.

The justices did not explain their reasoning, as is typical, and there were no noted dissents.

Prosecutors, though, said the company had agreed in a settlement to pay $40 million, and because Shkreli masterminded the scheme he should bear responsibility for repaying profits.

New York Attorney General Letitia James applauded the court’s action upholding the order, which also included a lifetime ban on Shkreli working in the pharmaceutical industry.

“This win reinforces how our state’s tough anti-fraud laws help protect New Yorkers and ensure bad actors cannot abuse their power, wealth, or influence,” she said in a statement.

Thomas Huff, a lawyer for Shkreli, said the decision was disappointing. But he also said the high court could yet overturn a lower court decision that made the $64 million penalty order possible even though Shkreli hadn’t personally gotten the money.

“If and when the Supreme Court does so, Mr. Shkreli will have a strong argument for modifying the order accordingly,” he said.

Shkreli was also ordered to forfeit the Wu-Tang Clan’s “Once Upon a Time in Shaolin,” the unreleased work that has been called the world’s rarest musical album. The multiplatinum hip-hop group put a single copy of the album up for auction in 2015, on the condition that it not be put to commercial use.

Shkreli was convicted of lying to investors and cheating them out of millions of dollars in two failed hedge funds he operated. Shkreli was CEO of Turing Pharmaceuticals — later Vyera — when it raised the price of Daraprim from $13.50 to $750 per pill after obtaining exclusive rights to the decades-old drug in 2015. It treats a rare parasitic disease that strikes pregnant women, cancer patients and AIDS patients.

He defended the decision as capitalism at work, saying insurance and other programs ensured that people who need Daraprim would ultimately get it. But the move sparked outrage, from the medical community to Congress.

Shkreli was released from prison in 2022 after serving much of a seven-year sentence.

A federal appeals court has sided with commercial fishermen who say proposed restrictions aimed at saving a vanishing species of whale could put them out of business.

The fishermen harvest lobsters and crabs off New England and oppose tough new restrictions on the way they fish that are intended to protect the North Atlantic right whale. The whale numbers only about 340 in the world and it’s vulnerable to lethal entanglement in fishing gear.

The fishermen and the state of Maine appealed their case to the U.S. Court of Appeals for the District of Columbia Circuit after losing in a lower court. The appeals court said Friday it disagreed with the lower court’s ruling.

The appeals court ruling could mean that the federal government must take another stab at crafting new rules to protect the whales. The restrictions would limit where lobster fishers can fish and what kind of gear they can use to try to prevent the whales from becoming entangled in fishing ropes.

The changes would represent a potential worst-case scenario for the lobster fishing industry, wrote Douglas H. Ginsburg, the senior judge of the appeals court, in Friday’s ruling.

“The result may be great physical and human capital destroyed, and thousands of jobs lost, with all the degradation that attends such dislocations,” Ginsburg wrote.

The fishers sued the National Marine Fisheries Service, an arm of the federal government. The service declined to comment on the lawsuit.
