The ACLU, the ACLU of Arizona, and the law firm Perkins Coie filed the case in 2015 against the Sheriff, the County Attorney, and other Pinal County, Arizona officials, for their enforcement of Arizona’s civil asset forfeiture laws. The defendants filed three motions to dismiss, but a federal court ruled on August 18, 2017, that the claims at the heart of the case can move forward. The judge found that the lawsuit establishes a plausible claim that the state’s asset forfeiture laws violate due process rights “because Defendants have a financial incentive to zealously enforce the forfeiture laws.”

Despite a federal court order from 2008, the Maricopa County jails – overseen by Sheriff Joe Arpaio –continue to skirt their constitutional responsibility for detainees' mental health. On April 1, 2016, the American Civil Liberties Union and the ACLU of Arizona – which have represented the detainees at the Maricopa County jails for close to 20 years – filed a motion to enforce the 2008 order. Many detainees with mental illnesses were still suffering unnecessarily from the scarcity and poor quality of the jails' care.
