Trophy hunts are halted on the day before they were to begin, when a federal court ruled the decision to strip Endangered Species Act protections from the grizzly bears of the Greater Yellowstone Ecosystem was illegal.

A year earlier, in defiance of the best available science, the U.S. Fish & Wildlife Service had removed federal protections, clearing the way for the hunts.

The U.S. EPA is forced by a federal court to end its delay of life-saving protections that safeguard first-responders and approximately 177 million people who live, work, and go to school within the worst-case scenario zones for industrial chemical disasters.

The agency had been delaying implementation of the protections since March 2017, based on petitions from industry trade associations.

A three-judge panel orders U.S. EPA to decide whether to ban chlorpyrifos, a dangerous pesticide known to harm human health, water, and wildlife. The agency had, in 2017, reversed its own proposal, refusing to ban chlorpyrifos.

U.S. EPA has continued to refuse to take action. On Aug. 6, 2019, Earthjustice again took the administration to court for its defiance of the law and science.

The administration violated the law when it opened up America's public lands to coal leasing just two months after coming into office, ruled a federal court.

The pause in coal leasing on federal public land had been ordered in 2016 to allow time to review and reform the federal program to ensure protection of the climate.

A federal court rules U.S. EPA must tell the public where smog levels exceed safety standards. Once the designations are issued, the work of cleaning up elevated smog levels can finally begin.

The agency itself estimated that compliance with the 2015 ozone standard will save hundreds of lives and prevent hundreds of thousands of asthma attacks in children every year.

At the 11th hour, a federal court halts a copper mine from desecrating Native American Tribes’ ancestral grounds.

The court fundamentally disagreed with the U.S. Forest Service's assumption that a mining company had the right to obliterate public lands to pave the way for quick profits for the company.
