Supreme Court Halts EPA's Cross-State Air Pollution Rule

The 5-4 decision temporarily blocks the Biden administration's plan to reduce ozone pollution while legal challenges proceed.

The Supreme Court's stay affects 23 states, primarily targeting power plants and industrial sources of ozone.
Justice Neil Gorsuch, writing for the majority, questioned the EPA's cost-effectiveness analysis.
Justice Amy Coney Barrett, in dissent, argued that the EPA had sufficiently justified its plan.
The EPA's rule aimed to help downwind states meet national air quality standards.
The case will continue in the D.C. Circuit Court, with potential hearings in the fall.
