Abstract
Older statutes sometimes alter the legal content of newer statutes in a way not apparent from the text of the newer statutes. The puzzle is how, even if a new statute is the choice of the current polis, the legal content created in part by the elderly statute is also the choice of the current polis. I consider several possible answers, including a legislative intent account and Dworkin’s, and argue that none of them is satisfactory. I then offer my own account, the De Re Account, which depends on distinguishing choosing under a description from choosing de re and noting that background norms and conventions sometimes determine what one does. In the case of legislation, because of the pragmatic norms for legal language and conventional practices against which a legislature acts, the legal content of the newer statute is chosen de re.
