Twenty-two young Americans, 10 of whom prevailed in the Held v. Montana constitutional climate case, are suing the Trump administration over its climate and energy policies.

The plaintiffs argue in a federal lawsuit filed Thursday that by dismantling climate protections and working to “unleash” American energy, the executive branch is violating the separation of powers clause in the U.S. Constitution. The plaintiffs also argue that the president’s executive orders are threatening their rights to life and liberty.

The lead plaintiff in the litigation is Eva Lighthiser, a 19-year-old Livingston resident who also was a plaintiff in a constitutional lawsuit that challenged Montana’s permissive approach to approving fossil fuel projects. Lighthiser is joined by Rikki Held and eight other plaintiffs from the Montana litigation, as well as a handful of young Americans from Hawaii, Oregon, Florida and California.

During a seven-day bench trial in 2023, the Held lawsuit focused an international spotlight on Montana and its unique constitutional guarantee of a “clean and healthful environment,” which the district court — and later the Montana Supreme Court — interpreted to include a “stable climate system.”

The federal lawsuit Lighthiser and her co-plaintiffs filed on May 29 challenges three executive orders that Trump issued during the first three months of his second term in the White House. The plaintiffs argue that the orders have suppressed climate science and slowed the transition to renewable energy sources in favor of fossil fuels, “thereby worsening the air pollution and climate conditions that immediately harm and endanger Plaintiffs’ lives and personal security.”

The plaintiffs are asking the court to invalidate the executive orders and direct Trump and the 11 federal agencies listed as defendants not to implement or enforce them.

“President Trump’s EOs falsely claim an energy emergency, while the true emergency is that fossil fuel pollution is destroying the foundation of Plaintiffs’ lives,” the 126-page filing reads. 

In a press release about the lawsuit, Lighthiser described Trump’s fossil fuel directives as a “death sentence for my generation.”

“I’m not suing because I want to — I’m suing because I have to,” said Lighthiser, who plans to pursue environmental studies in college. “My health, my future, and my right to speak the truth are all on the line. [President Trump is] waging war on us with fossil fuels as his weapon, and we’re fighting back with the Constitution.”

In an email to Montana Free Press on Thursday, White House spokesperson Taylor Rogers defended Trump’s energy agenda.

“The American people are more concerned with the future generations’ economic and national security, which is why they elected President Trump in a landslide victory to restore America’s energy dominance. Future generations should not have to foot the bill for the lefts’ radical climate agenda,” Rogers wrote. 

In addition to enumerating the climate harms plaintiffs have reported, including wildfire-related and heat-induced visits to the emergency room, diminished career opportunities, property damage spurred by extreme weather events and a loss of cultural and recreational traditions, the complaint outlines tensions between Trump’s executive orders and the missions of congressionally authorized agencies such as the U.S. Environmental Protection Agency.

One of the executive orders named in the lawsuit directs federal agencies to identify and rescind actions that place an “undue burden” on the “identification, development or use of domestic energy resources — with particular attention to oil, natural gas, hydropower, biofuels, critical mineral and nuclear energy resources.” Another directs executive branch agencies to use emergency powers to facilitate energy companies’ access to federally-owned energy resources and the infrastructure required to transport and process them. The third focuses on the development and prioritization of coal-fired electricity.

In the Held v. Montana case, the Montana Supreme Court directed the state to develop a system for inventorying and disclosing greenhouse gas emissions associated with large projects seeking state-issued permits. This spring, the Montana Legislature adopted a framework that state agencies like the Montana Department of Environmental Quality can use to quantify greenhouse gas emissions.

Many of the same attorneys who argued the Held v. Montana case are representing the plaintiffs in this litigation, including Roger Sullivan of Kalispell. Three of the plaintiffs’ attorneys in the case work for Our Children’s Trust, an Oregon-based nonprofit focused on climate litigation that spent the better part of a decade fighting the federal government in the Juliana v. United States lawsuit, a federal constitutional climate case that concluded earlier this year in the government’s favor.

(Missoula Current) Montana appears to have a new invasive species, and this one could come with a few nasty parasites.

The Montana Department of Public Health and Human Services announced last week that three blacklegged ticks, also called deer ticks, have been found in eastern Montana over the past year. While the ticks aren’t necessarily pleasant, the real problem is that they’re known to carry Lyme disease, in addition to several other parasites that can infect people and animals.

The first blacklegged tick was found in Dawson County around Glendive earlier in 2024. A man found the tick on his hunting dog and sent it to the Montana State University Extension’s Schutter Diagnostic Lab, where diagnostician Marni Rolston identified it. Rolston collaborated with scientists at the National Institutes of Health’s Rocky Mountain Laboratory in Hamilton to confirm the identification.

“This discovery is incredibly important because it greatly expands the geographic range of the blacklegged tick, a carrier of the pathogen that causes Lyme Disease,” said Bob Peterson, an MSU entomologist in a release. “The implications of finding this tick in Montana cannot be overstated.”

In the fall of 2024, two more ticks were found in Sheridan County in far northeast Montana, an area popular for bird hunting, and DPHHS, along with the Centers for Disease Control and Prevention, confirmed they were blacklegged ticks.

The percentage of blacklegged ticks that are infected with Lyme disease ranges from none to more than 50% of a population, depending on the area and life stage. Lyme disease infection occurs mostly in the northeastern, mid-Atlantic, and north-central United States, according to the CDC. Blacklegged ticks found in most areas of the southeastern United States are almost never infected.

Lyme disease can produce a wide range of symptoms, depending on the stage of infection. These include fever, rash, facial paralysis, an irregular heartbeat and arthritis.

No pathogens were found on the ticks in Montana, according to the DPHHS. But their presence means Montanans should be alert, particularly in Dawson and Sheridan counties, said Devon Cozart, DPHHS vector-borne disease epidemiologist.

“The presence of this new type of tick in the state could mean that Montanans have an increased risk of exposure to diseases that weren’t previously a threat in Montana,” Cozart said in a release. “These ticks could have been carried into the state by a host animal, or they could be active and reproducing here – we just don’t know yet. We will be conducting further investigations this spring.”

Blacklegged ticks are not native to Montana. Research indicates they survived the Ice Age in the southeastern U.S. and then steadily expanded northward during the 20th century, spurred by reforestation, a warming climate and animal hosts moving north. In addition, blacklegged ticks have subsequently been spreading west, followed by the lone star tick.

Research has shown that several species can serve as migration vectors for ticks, including deer and migratory birds. People can also factor in, because they move animals around, including horses and dogs. In recent years, the number of nonresidents using eastern Montana to train their dogs in the winter and hunt in the fall has surged. Just like ticks can be carried into your house, one or two ticks could hitch rides to Montana on nonresident dogs from the hotbeds of Minnesota, Iowa and Wisconsin.

If anything, dog owners should be concerned because pets can get Lyme disease too. In most cases, a tick must be attached for more than 24 hours before the Lyme disease bacterium can be transmitted, according to the CDC. If you remove a tick within 24 hours, you can greatly reduce the chances of you or your pets getting Lyme disease.

According to the CDC, the established populations currently closest to Montana are in the eastern portions of the Dakotas and throughout Minnesota. A November 2023 CDC scientific review concluded that, because black-legged ticks have established in counties in the far eastern parts of Nebraska and the Dakotas, “it is reasonable to assume that (blacklegged ticks) invaded in recent decades from the eastern neighboring states of Minnesota and Iowa.”

The map showing tick presence could change to include Montana if researchers find more ticks. To that end, DPHHS is launching a citizen-scientist program and is requesting the public’s help in tick surveillance, especially in Dawson and Sheridan counties. Anyone who thinks they have found a blacklegged tick is encouraged to fill out this online form.

Montana is home to the Rocky Mountain wood tick and the American dog tick, which can also spread diseases such as Rocky Mountain spotted fever and Colorado tick fever. These ticks tend to be brown and are much larger than the dark-red deer tick.
