Suppose there is a US federal regulation that asserts a particular interpretation of a statue (in particular, that a certain class of documents is included among those designated by a phrase in the statute). If the regulation is repealed, can the executive continue to assert that interpretation?
This question was inspired by Can "evidence of registration" be a "certificate of registration"? because I have learned that there was a regulation explicitly answering that question in the affirmative, but the regulation was repealed in 1960.
