President Trump signs Laken Riley Act into law

U.S. Capitol

Key Takeaways

On January 29, President Trump signed the bipartisan Laken Riley Act (S.5/H.R. 29) into law, requiring the U.S. Department of Homeland Security (DHS) to detain any undocumented immigrant who has been arrested for violent or property-related crimes and giving states new authority to sue the federal government over certain immigration-related decisions.  

How will this law impact mandatory detention?  

S. 5/H.R. 29 expands the list of crimes that require Immigration and Customs Enforcement (ICE) to detain undocumented immigrants. Under existing law, undocumented immigrants who are accused, arrested or convicted of committing certain serious crimes are required to be detained by ICE. The new legislation expands this list to include property-related crimes such as theft and burglary, as well as assault on law enforcement. There are no exceptions for children. Depending on state and local ordinances, counties may be required to report these arrests to ICE.

What happens if a county reports an undocumented immigrant charged with a crime to ICE?

If a county reports an undocumented immigrant to ICE, the agency is now required to issue a detainer to the county and take the individual into federal custody. The legislation does not obligate counties to hold the individual until ICE arrives. In some cases, counties have faced legal challenges related to holding individuals under ICE detainers.

Existing law mandates detention for individuals accused or convicted of serious crimes, but ICE has stated that it lacks the resources to enforce these requirements adequately. In December, ICE issued a memo indicating that without additional funding, the agency may need to release individuals back into local communities if the Laken Riley Act is enacted. Additionally, local prosecutors may be unable to carry out criminal prosecutions of individuals who are taken into federal immigration custody.

How does this legislation impact states? What types of new authorities are granted to states?

The Laken Riley Act (S.5/H.R. 29) proposes changes to current Supreme Court precedent, granting state governments the ability to sue the federal government over certain immigration-related decisions. This includes providing states with standing to challenge changes in federal immigration enforcement priorities, such as decisions to focus on deportations of individuals convicted of violent crimes rather than those accused of lesser offenses. The legislation also allows states to pursue lawsuits regarding court-ordered visa bans for countries that do not accept repatriated individuals.
