The recent Supreme Court ruling has curtailed federal agencies' power to regulate environmental, health, and labor policy areas, impacting a wide range of areas including climate change. Chief Justice John Roberts authored the decision, with five conservative justices aligning, while three liberal justices dissented. President Joe Biden's climate rules face potential legal challenges as a result of the ruling. The court's skepticism towards federal agencies aligns with past conservative rulings, reflecting a shift in regulatory scrutiny. The decision's impact on EPA's climate regulation under the Clean Air Act may introduce legal vulnerability despite existing legal obligations.
