This chapter advances theoretical reasons to support symmetric interpretation. First, favoring symmetry accords with the Constitution’s character as a comparatively terse, “framework” document focused on establishing democratic procedures rather than definitive policies. Second, an ethic of symmetric interpretation accords with widely accepted features of judicial role-morality. Finally, symmetric interpretation accords with the framers’ own constitutional aspirations and interpretive methods. Multiple widely accepted theoretical considerations in constitutional law thus support preferring symmetric understandings when possible.
