Eight lawsuits related to the 2020 Census have been filed by state and local governments, civil rights and professional organizations, and concerned individuals. Seven are known to be against the addition of the citizenship question in the 2020 Census, one in support.
The two New York cases were consolidated into one on September 14, 2018. The trial began on November 5, 2018 and ended on November 27, 2018. Judge Jesse Furman ruled against the Trump Administration in the New York District Court and blocked the citizenship question in the 2020 Census on January 15, 2019.
The two California cases began on January 7, 2019. Judge Richard Seeborg ruled in March 2019 that the citizenship question is unconstitutional and a violation of a federal statute.
The two Maryland cases began on January 22, 2019. Judge George Jarrod Hazel ruled in April 2019 that the decision to include it on forms for the 2020 Census was unlawful.
The most recent case was filed by Electronic Privacy Information Center on November 20, 2018.
The Supreme Court has scheduled to begin hearings on the citizenship question on April 23 at 10 a.m.
