Energy in the Judiciary
limate change litigation has been a vibrant industry for two-plus decades, especially in the wake of the Supreme Court’s decisions in Massachusetts v. EPA (2007) and American Electric Power v. Connecticut (2011). State Attorneys General have played a central role, both in litigation over federal agencies’ rules and in cases challenging individual states’ efforts to compel sister states to reduce greenhouse gas emissions or to recoup damages from major producers in those states. This Article provides casual empirical data on state AGs litigation agenda. Their initiatives and interventions, I argue, have nothing to do with public-regarding benefits. They have everything to do with “horizontal federalism”—specifically, states’ competition for productive capital and labor. “Red” states seek to exploit their competitive and comparative advantages in producing cheap and abundant energy; “blue” states seek to shape and mobilize federal and state law for the purpose of raising their red-state rivals’ costs. This carbon war is fought on an open field: the Supreme Court has no coherent view of what states may or may not do to each other. It appears to have no interest in the question and has in many respects encouraged mutual state aggression. A deeply divided polity and for that matter the U.S. Constitution demand a more confident and constructive judicial role. The Article concludes with thoughts on what a coherent federalism jurisprudence, along the lines of constitutional argument that the Roberts Court has deployed in separation of powers cases, might plausibly look like.
