The TRUST Act, which went into effect Jan. 1, prevents local law enforcement from detaining noncitizens pursuant to an immigration hold or detainer, beyond the time that they otherwise could be released from criminal custody. See Immigrant Legal Resource Center, Guide, California TRUST Act: A Guide for Criminal Defenders, http://www.ilrc.org/crimes. This Guide discusses how the TRUST Act works and defense strategies in light of the Act.
