State v. Engel
The Minnesota Supreme Court is poised to decide whether there are any circumstances in which someone subjected to an unconstitutional traffic stop can suppress evidence that he temporarily avoided the police when they initiated the unconstitutional stop. The Minnesota Court of Appeals held that evidence of even temporary “flight” can never be suppressed—even when someone simply delays acquiescing to an unconstitutional traffic stop—on the theory that fleeing from the police is a crime. The ACLU’s State Supreme Court Initiative, along with the ACLU of Minnesota and the law firm Faegre Drinker Biddle & Reath LLP, filed an amicus brief arguing that Article I, Sections 8 and 10 of the Minnesota Constitution—which guarantee Minnesotans remedies for constitutional violations and protect them from unreasonable searches and seizures—require a broad application of the exclusionary rule. Accordingly, we argue that the Court should use a flexible, multi-factor test that can allow for suppression of evidence where a suspect, as in this case, responds to an illegal stop or seizure with nonviolent attempts to keep himself safe.

Energy Transfer LP v. Greenpeace International, Unicorn Riot
This case in the Minnesota Supreme Court asks whether the MFFIA's protections apply to newsgatherers even if they are alleged to have engaged in trespassing while newsgathering. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Minnesota and law firm Biersdorf & Associations, filed a brief representing Unicorn Riot, a media organization that covered protests of the Dakota Access Pipeline. The brief argues that MFFIA and constitutional reporter’s privileges, under both the U.S. and Minnesota constitutions, protect Unicorn Riot from having to comply with Energy Transfer’s subpoenas.

State v Malecha
In this case, the Minnesota Supreme Court is considering the scope of a crucial doctrine that protects criminal defendants from being convicted based on evidence obtained in violation of their constitutional rights. Under both the U.S. and Minnesota Constitutions, courts apply an “exclusionary rule” that allows criminal defendants to seek the exclusion of evidence obtained in violation of their rights. For nearly 40 years, the U.S. Supreme Court has chipped away at the exclusionary rule by adopting and expanding the “good faith exception,” a doctrine providing that in some situations courts need not exclude evidence obtained in violation of the Constitution. In this case, officers acquired evidence after arresting someone based on a warrant that was listed as valid due to a recordkeeping error, but which in fact should have been recalled. In July 2023, together with other ACLU attorneys and partners, the SSCI submitted an amicus brief to the Minnesota Supreme Court asking it to hold as a matter of state constitutional law that the exclusionary rule applies to this situation, and that the good-faith exception does not apply. In March 2024, the Court ruled in the ACLU's favor, stating that the district court did not err in finding that the defendant's arrest warrant had been quashed before her arrest and the good-faith exception did not apply.
