Battle lines over President Trump's nominee for a new U.S. Supreme Court justice are now being drawn, as they should be, over crucial issues such as a woman's right to choose, health care, immigration, civil rights and criminal justice. In past nomination fights, little attention has been paid to the court's role in shaping environmental law and science-based regulation. But it would be a major mistake to overlook these issues now. The Supreme Court has an enormous impact on how U.S. environmental laws are interpreted and enforced, and a new justice could tip the balance against science-based rules on climate change, clean air and clean water.
