There is a popular belief among statutory interpretation scholars that substantive canons of statutory construction—that is, policy-based background norms or presumptions such as the rule of lenity and the canon of constitutional avoidance—act as an “escape valve” that helps textualist judges eschew, or “mitigate,” the rigors of textualism.
