The proposed bill, titled the "Defense Against Criminal Illegals Act," aims to establish enhanced penalties for illegal aliens who commit serious felonies involving violence. It defines serious felonies to include offenses such as murder, aggravated assault, and terrorism, among others. If an individual is convicted of a serious felony while illegally present in the United States, the penalties will be escalated based on the classification of the felony, potentially resulting in a Class Y felony for the most severe cases. Additionally, the bill mandates that individuals convicted under this section will not be eligible for early release on parole or other forms of supervised release for the enhanced portion of their sentence.

Furthermore, the bill expands the state's ban on sanctuary policies to include counties and unincorporated areas, ensuring that local governments cannot adopt policies that limit cooperation with federal immigration authorities. It also allows sheriff's offices and the Division of Correction to participate in the Warrant Service Officer Program, which enables state and local law enforcement to execute administrative warrants under federal immigration law. The bill outlines procedures for applying to this program and stipulates that if a local government is found to have enacted a sanctuary policy, it will be ineligible for state-administered discretionary funds until the policy is repealed.
