CLE Training: Immigration Detainers in NYC: The Impact on State Criminal Cases

Immigration detainers are a key component of ICE’s detention-to-deportation pipeline.  An immigration detainer is an administrative request to state or local law enforcement to detain individuals who would otherwise be released, or notify ICE in advance of release, so that ICE can arrest the person. State and local law enforcement are not required to honor detainers but many do. ICE relies on state and local law enforcement as a “force multiplier” which increases their ability to detain and deport people. 

In 2014, New York City council passed local laws to limit the ability of the Department of Corrections (“DOC”) and NYPD to honor detainers. In practice, this means that the City should only cooperate with ICE in limited situations. While the detainer laws sometimes clearly apply, there are some situations that are not explicitly addressed by the law and how DOC interprets the law may be at odds with how advocates and city council intended the law to operate.

The Immigrant Defense Project regularly advises defense attorneys on detainers and will share some of the obstacles in answering the deceptively simple question of “will my client be turned over to ICE if they are released from custody?” This training will provide background about the use of detainers by ICE, review New York City laws governing when a detainer may be honored, and suggest tips for advocating for the safe release of clients in DOC custody. This training is recommended for assigned and privately retained defense attorneys.
