Washington — The Supreme Court on Thursday agreed to block an environmental rule that aims to curb air pollution and address harmful smog that travels from certain states into others while legal proceedings continue.

In a 5-4 decision, the court granted the request from Ohio, Indiana and West Virginia, as well as energy companies and industry groups, to pause the rule. Justice Neil Gorsuch authored the majority opinion.

The dispute involved the Clean Air Act's "good neighbor" provision, which aims to address interstate pollution issues. The law requires the Environmental Protection Agency to set federal standards for the amount of certain pollutants that can be safely in the air. When the agency sets air quality standards, states must submit implementation plans to meet them.
