High Court Weighs State Role in Prosecuting Immigrants Associated Press The Supreme Court is trying to sort out whether states can prosecute immigrants who use fake Social Security numbers to get a job. The justices heard arguments Wednesday in Kansas' appeal of a state court ruling that threw out three convictions after concluding the state was seeking to punish immigrants who used fake IDs to obtain jobs. The Kansas Supreme Court ruled that the federal government has exclusive authority to determine whether an immigrant may work in the United States. The justices seemed concerned that states shouldn't be hampered in other identity-theft prosecutions when someone might use a stolen Social Security number to get a driver's license or arrange for direct deposit of a paycheck. The case arose from three prosecutions in Johnson County, a largely suburban area outside Kansas City where the district attorney has aggressively pursued immigrants under the Kansas identity theft and false-information statutes. The convictions under state law could alter immigration status and lead to deportation. The issue is whether Kansas is blocked from prosecuting those crimes because it is relying on information that is on a required federal work authorization form, the I-9. Kansas, backed by the Trump administration and 12 states, argues it can prosecute because the same information also appears on state work forms. In 2012, the court ruled that portions of an Arizona law targeting immigrants without proper legal documents could not be enforced because federal law trumps state measures in the area of immigration. The three immigrants in the Kansas case say the high court's Arizona decision should determine the outcome in their situation. .
