The Supreme Court will hear a case Tuesday that could redefine the scope of federal environmental reviews under the National Environmental Policy Act.

The eventual ruling in the case Seven County Infrastructure Coalition v. Eagle County could clarify whether federal agencies must evaluate the environmental effects of decisions they make, even if that involves addressing ramifications that go beyond the agencies’ jurisdiction and expertise — a question pivotal for infrastructure development like roads and highways or efforts to prevent overcrowding in national parks. It could also set the tone for how federal agencies address the effects of federal development projects on the climate under the incoming Trump administration, as Trump himself has criticized the law as stalling construction.
