President Barack Obama garnered his second legal victory this month in his effort to clean up coal-fired power plants, as the U.S. Supreme Court upheld a rule designed to cut pollutants that cause smog and acid rain.
The justices, voting 6-2 to overturn a lower court, backed an Environmental Protection Agency rule targeting air pollution that crosses state lines. Advocates for utilities and coal producers argued that the EPA’s approach was too intrusive and would force plants to clean up more pollution than necessary to deliver clean air in downwind states.
