Voting Rights
United States v. DeMarinis
The Department of Justice (“DOJ”) sued Maryland demanding the release of its full, unredacted voter file, which includes the highly sensitive and personal data of every voter in the state. This suit appears to be part of DOJ’s effort to build a national voter database without congressional authorization, improperly question the validity of state voter rolls, and intimidate eligible voters in Maryland and around the country.

Roland Branch v. State of Maryland
This petition to the Supreme Court of Maryland asked the court to reconsider its adherence to Whren v. U.S., 517 U.S. 806 (1996), which declared that a traffic stop undertaken for pretextual reasons does not violate the Fourth Amendment to the U.S. Constitution so long as the police have probable cause to believe that a traffic violation occurred. The ACLU, alongside the ACLU of Maryland, filed an amicus brief in support of the defendant’s petition, in which the ACLU argued that the court should take up the question of whether pretextual stops violate the Maryland Constitution. In September 2024, the Court denied the petition.
