Good question! This refers to caselaw from courts that predate the United States, such as Maryland and Massachusetts: https://api.case.law/v1/cases/ https://api.case.law/v1/cases/ State courts didn't come into existence with the US Constitution -- the Massachusetts Supreme Judicial Court, for example, dates back to 1692, and those precedents are still "good" in some sense though unlikely to be cited. We don't have English precedents, unfortunately, as guessed by some sibling comments.
