The plaintiffs in a Maryland case that challenges the addition of a citizenship question to the 2020 census on Tuesday won the opportunity to present new evidence that purports to show U.S. officials acted with discriminatory motivations in moving to require survey-takers to identify their status in the country.

The ruling by a divided panel of the U.S. Court of Appeals for the Fourth Circuit allows additional proceedings in the trial court, and it comes as the U.S. Supreme Court prepares to announce a decision on a separate but related census case that came to the justices from New York federal district court. The justices could issue a ruling as early as Wednesday on whether the Trump administration acted lawfully in adding the citizenship question.
