In response to concerns raised by the Citing Slavery Project, the Bluebook has made a rare between-edition change to rule 10.7.1 on citation to cases. This change is reflected in the 2021 printing of The Bluebook Twenty-First Edition was first published in 2020.
Rule 10.7.1(d) now covers slave cases. For cases involving an enslaved person as a party, use the parenthetical “(enslaved party).” For cases involving an enslaved person as the subject of a property or other legal dispute but named as a party to the suit, use the parenthetical “(enslaved person at issue).” For other cases involving enslaved persons, use an adequately-descriptive parenthetical.
Dred Scott v. Sanford, 60 U.S. (19 How.) 393 (1857) (enslaved party), superseded by constitutional amendment, U.S. Const. amend. XIV.
Wall v. Wall, 30 Miss. 91 (1855) (enslaved person at issue).
