WASHINGTON (AP) — Attorney General Merrick Garland on Friday rescinded a Trump-era memo that curtailed the use of consent decrees that federal prosecutors have used in sweeping investigations of police departments.

Garland issued a new memorandum to all U.S. attorneys and other Justice Department leaders spelling out the new policies on civil agreements and consent decrees with state and local governments.

The memo comes as the Justice Department shifts its priorities to focus more on civil rights issues, criminal justice overhauls and policing policies in the wake of nationwide protests over the death of Black Americans at the hands of law enforcement.

In easing restrictions placed on the use of consent decrees, the Justice Department is making it easier for its prosecutors to use the tool to force changes at police departments and other government agencies with widespread abuse and misconduct.

The memo in particular rescinds a previous memo issued by then-Attorney General Jeff Sessions shortly before he resigned in November 2018.

Democrats have long argued the ability of the Justice Department's civil rights division to conduct sweeping probes of police departments had been curtailed under President Donald Trump. The so-called pattern or practice investigations examine whether systemic deficiencies contribute to misconduct or enable it to persist.

"This memorandum makes clear that the Department will use all appropriate legal authorities to safeguard civil rights and protect the environment, consistent with longstanding Departmental practice and informed by the expertise of the Department's career workforce," Garland said.

The Justice Department didn't totally ban pattern or practice investigations under Trump, but former Attorney General William Barr suggested they may have been previously overused.

As attorney general in the Obama administration, Eric Holder frequently criticized violent police confrontations and opened a series of civil rights investigations into local law enforcement practices. The civil rights investigations often ended with court-approved consent decrees that mandated reforms.

The consent decrees included those with the police in Ferguson, Missouri, after the killing of Michael Brown and in Baltimore following the police custody death of 25-year-old Freddie Gray.
