The Supreme Court ruled unanimously in favor of an Idaho couple in a landmark case that weakens the Clean Water Act. The Sacketts had challenged the EPA's compliance order claiming their land was subject to the law, arguing that their land did not contain wetlands subject to federal oversight. The decision is a major victory for property rights advocates and a setback for environmental groups, and will likely have far-reaching implications for the scope of the law and the ability of the EPA to regulate water pollution.
