A federal judge on Thursday issued a clarification order stating that the Census Bureau must inform its employees that it is not changing the deadline for its 2020 census data collection efforts.

The ruling outlines the bureau’s “repeated violations” of a preliminary injunction issued by Lucy Koh, district judge of the Northern District of California, that blocked the bureau from moving the census deadline from Oct. 31 to Sept. 30. The “most egregious” of those violations, Koh said, was a one-sentence tweet on Monday.
