In March 2018 Secretary of Commerce Wilbur Ross issued a memorandum stating a citizenship question would be added to the 2020 census questionnaire. In In Re Department of Commerce the Supreme Court will not be deciding whether this question may be legally added. Instead, the Court will decide—among other things—whether Secretary Ross may be deposed as to his motives for adding this question.
A number of state and local governments and nonprofits sued the Secretary claiming that adding this question is arbitrary and capricious in violation of the Administrative Procedure Act.
In the 2018 memorandum Secretary Ross stated that he “began a thorough assessment” of whether to add a citizenship question “[f]ollowing receipt” of a December 2017 letter from the Department of Justice (DOJ) requesting citizenship data to enforce the Voting Rights Act’s prohibition against diluting the voting power of minority groups.
