For its lay audience City Journal asked me to explain the King v. Burwell decision, which permitted federal exchanges under the Affordable Care Act to receive subsidies. Within its brief compass, I made two points.
First, I suggested, contrary to some conservative commentators, that the majority opinion did not demonstrate that Chief Justice Roberts was unprincipled but that instead the decision followed from a principled purposivist theory of statutory interpretation. I showed why the theory was wrong: like Mike Rappaport, I believe the meaning of the provision was clear and neither purposivist nor intentionalist interpretation should be allowed to defeat a clear meaning. This analysis of Roberts’ opinion comports with my more general view that four justices labeled conservatives are often fractured, because they are more legalists than ideologues, whose different interpretive methods lead to different results that are sound under their principles even when the principles are unsound.
Second, I noted that the effects of purposive interpretation are generally friendly to progressivism because it allows judges to choose overriding purposes that advance progressive goals that were not written into law. But let me be clear that any aid that purposivism gives to progressivism is not a reason to reject purposivism, just an effect of that interpretive method.
Here is an analogy.
