The high court acknowledged studies finding that 6 percent to 9 percent of Arizona's population is there illegally. One study cited by the court found that this segment of the state's population was responsible for 21.8 percent of its felonies. The court noted that problems related to illegal immigration in the state must not be underestimated.
But none of that prevented the court from striking down Arizona's best effort to address those problems. The message to other states: No matter how bad illegal immigration gets, you won't be allowed to do much about it.
The court did preserve a narrow opening for state action to restrict illegal immigration. As determined last year in Chamber of Commerce v. Whiting, states can revoke the business licenses of employers who hire illegal immigrants without checking their documentation using the E-Verify system. Hazleton, Pa., made similar use of licensing powers in its anti-illegal immigration ordinances.
The high court also upheld Arizona's requirement that police check the immigration status of those they stop or arrest if there is a reasonable suspicion that they're in the country illegally. The federal government had not attacked that provision as authorizing racial profiling because the same argument could be used against federal immigration laws. In fact, such immigration status checks are already standard operating procedure in many jurisdictions throughout the United States. Arizona lawmakers made it a legal requirement because certain "sanctuary" cities were telling their police not to check immigration status.
Overall, the court's ruling prolongs the current U.S. policy of keeping numerical immigration limits on the books but declining to enforce them. Moreover, it prohibits most state enforcement of those limits. If Congress repealed all our immigration laws and welcomed everyone who would like to enter the country, that would at least be intellectually coherent. The current policy makes no sense.
By rewarding and protecting illegal immigrants, we are punishing the millions awaiting their chance to immigrate legally. With so little risk that immigration law will be enforced, those who immigrate illegally get the last laugh.
