The Supreme Court is putting the Environmental Protection Agency’s air pollution-fighting “good neighbor” plan on hold while legal challenges continue, the conservative-led court’s latest blow to federal regulations.

The justices in a 5-4 vote on Thursday rejected arguments by the Biden administration and Democratic-controlled states that the plan was cutting air pollution and saving lives in 11 states where it was being enforced and that the high court’s intervention was unwarranted.

The rule is intended to restrict smokestack emissions from power plants and other industrial sources that burden downwind areas with smog-causing pollution. It will remain on hold while the federal appeals court in Washington considers a challenge to the plan from industry and Republican-led states.

It’s a scenario that terrifies America’s auto industry.

Chinese carmakers set up shop in Mexico to exploit North American trade rules. Once in place, they send ultra-low-priced electric vehicles streaming into the United States.

As the Chinese EVs go on sale across the country, America’s homegrown EVs — costing an average of $55,000, roughly double the price of their Chinese counterparts — struggle to compete. Factories close. Workers lose jobs across America’s industrial heartland.

Ultimately, it could all become a painful replay of how government-subsidized Chinese competition devastated American industries from steel to solar equipment over the past quarter-century.
