This legislation significantly amends the Immigration and Nationality Act by mandating the detention of certain aliens. Specifically, it requires the Secretary of Homeland Security to take into custody any alien who is inadmissible under specified grounds and has been charged with, arrested for, convicted of, or admits to committing acts constituting burglary, theft, larceny, or shoplifting . The bill defines these theft-related terms according to the jurisdiction where the acts occurred and obligates the Secretary to issue a detainer for such aliens and expeditiously take custody. Beyond mandatory detention, the bill expands the enforcement powers of state attorneys general. It grants them, or other authorized state officers, standing to bring civil actions against the Secretary of Homeland Security, the Attorney General, or the Secretary of State for alleged violations of various immigration detention, removal, and parole requirements. These actions can be pursued if the alleged violation harms the state or its residents, with harm defined to include financial harm exceeding $100. The legislation also ensures that courts will advance and expedite the disposition of these state-initiated lawsuits, and it modifies existing limitations on injunctive relief to allow for such actions.
