Criminal Law Reform
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.

Reproductive Freedom
Moira Akers v. State
This case concerns whether prosecutors can admit evidence that a person exercised their right to decide whether to terminate their pregnancy as proof of intent for murder. Here, the prosecution’s use of this evidence at Moira Akers’ trial denied her due process, resulting in an unjust conviction and a 30-year prison term. The ACLU’s Abortion Criminal Defense Initiative, alongside the ACLU of Maryland, filed an amicus brief arguing that allowing admission of this evidence not only violated Ms. Akers’ rights but chills the right of all Marylanders to freely decide whether to continue or end their pregnancies. The Maryland Supreme Court issued a ruling on February 19th, 2025 overturning Moira Akers’ conviction on the grounds of inadmissible evidence.
