Immigration Checks

When is it OK to check a person's status?

Except for Native Americans, everyone in the United States is an immigrant, or the descendant of immigrants. Most of us are here legally, but a significant number are not. Under what circumstances is it permissible to inquire into a person’s immigration status? The Supreme Court has addressed this question in several opinions, most recently in its 2012 decision reviewing Arizona’s immigration statutes.

U.S. v. Brignoni-Ponce

By now, police officers are well aware that detentions cannot be based on racial profiling. But more than 35 years ago, border patrol officers sometimes relied on the apparent race of a suspect as an indication of possible violation of immigration laws. In Brignoni-Ponce, for example, officers stopped a vehicle not far from the Mexican border to see if its occupants were illegal aliens, based on nothing but their apparent Mexican ancestry. The Supreme Court found the stop to be unreasonable under the Fourth Amendment, saying this:

"We cannot conclude that this furnished reasonable grounds to believe that the three occupants were aliens. The Fourth Amendment forbids stopping or detaining persons for questioning about their citizenship on less than a reasonable suspicion that they may be aliens."

Although Brignoni-Ponce made clear that a suspicionless detention may not be made for the purpose of checking on immigration status (except at ports of entry and nearby fixed checkpoints), the case did not decide whether or not such questioning required some level of suspicion if the detention was justified on other grounds, or if there were no detention at all. Two subsequent cases addressed these issues.

INS v. Delgado

Officers from the INS (Immigration and Naturalization Service), forerunner of today's ICE (Immigration and Customs Enforcement), went to a garment factory to check workers' immigration status. Some agents with badges and radios walked around the factory floor talking to workers, and they sometimes asked to see immigration documents. Other agents were stationed inside each exit.

Employee Herman Delgado filed a federal suit for an injunction to prevent the INS from conducting such checks. The Ninth Circuit of the U.S. Court of Appeals ruled that the INS violated the Fourth Amendment by questioning workers about their immigration status without any reasonable suspicion that the individuals who were questioned were illegally in the country.

The U.S. Supreme Court reversed. The court pointed out that while its earlier cases, such as Brignoni-Ponce, prohibited detentions without reasonable suspicion, the Fourth Amendment does not apply to mere questioning of an individual who has not been detained. Ruling that the INS was engaged only in consensual encounters in the factory, the court said this:

"Interrogation relating to one's identity or a request for identification by the police does not, by itself, constitute a Fourth Amendment seizure. What is apparent from our cases is that police questioning, by itself, is unlikely to result in a Fourth Amendment violation."

The Delgado decision established that during a consensual encounter, the Fourth Amendment does not prohibit government agents from asking about a person's immigration status and requesting to see immigration documents, even though there is no reasonable suspicion of alienage. Logically, wouldn't the same rule apply during a lawful detention?

Muehler v. Mena

Police officers with a search warrant went to a home to look for weapons and other evidence of a drive-by gang shooting. Iris Mena, an occupant of the residence, was detained during the search, although she was not one of the suspects. During her detention, INS agents accompanying the police questioned Mena about her citizenship and asked to see her immigration documents. She produced documents showing that she was a legal resident and later sued the officers for violation of her Fourth Amendment rights, based in part on the fact that she had been questioned about immigration status without any suspicion that she might be an illegal alien.

Both the District Court and the Ninth Circuit ruled for Mena and against the officers. The Ninth Circuit held that simply asking questions was Fourth Amendment activity that must be supported by reasonable suspicion. The officers appealed this ruling to the U.S. Supreme Court, which reversed.

The Supreme Court said that the Ninth Circuit had misinterpreted its earlier decisions holding that detentions to check immigration status would violate the Fourth Amendment when there was no reasonable suspicion of wrongdoing, but that these decisions had no application to mere questioning of one who was already lawfully detained, as Mena was during the search warrant service. The court summarized the law as follows:

"In our earlier cases, we certainly did not create a requirement of particularized suspicion for purposes of inquiry into citizenship status. The officers’ questioning of Mena did not constitute an independent Fourth Amendment violation. Hence, the officers did not need reasonable suspicion to ask Mena her name, date and place of birth, or immigration status."

Arizona v. United States

Frustrated by federal inaction in enforcing immigration laws and beset by public safety threats from unchecked immigration across its border with Mexico, the State of Arizona enacted its own set of laws to try to cope with some of the problems. One provision, section 2(b) of the Act known as S.B. 1070, requires law enforcement officers in Arizona to make "a reasonable attempt to determine the immigration status” of any person they stop, detain, or arrest on some other legitimate basis, if “reasonable suspicion exists that the person is an alien and is unlawfully present in the United States."

The United States sued to prevent the state from enforcing this provision (among others), arguing that the entire field of immigration enforcement was preempted from state control by federal law. The United States also argued that immigration checks could unlawfully prolong otherwise lawful detentions. On June 25, 2012, the U.S. Supreme Court rejected both of these contentions.

As to federal preemption, the court pointed out that various provisions of federal law specifically authorize mutual communication between local and federal officers on immigration matters. Quoting a lower court opinion, the court said that "Arizona officers have authority to enforce the criminal provisions of federal immigration law. If § 2(b) only requires state officers to conduct a status check during the course of an authorized, lawful detention or after a detainee has been released, the provision likely would survive preemption."

On the issue of whether state officers could routinely conduct immigration checks during lawful detentions, the court cited to its earlier decision in Muehler v. Mena, which had already decided this issue, "finding no violation where questioning about immigration status did not prolong a stop." In the absence of evidence that Arizona officers would be applying § 2(b) in such a way as to cause detentions to be unlawfully prolonged, the Supreme Court saw no reason to invalidate this particular provision. (Other unrelated provisions were found to be preempted by federal law.)

Recapitulation

Two constitutional rules for police can be taken from this body of decisions:

1. It is not OK to stop someone for an immigration check without reasonable suspicion.

2. During a consensual encounter or a lawful detention or arrest, it is OK to inquire into immigration status without any independent suspicion the person is in violation of immigration laws.

Nice to see how often the 9th Circuit gets things wrong in the eyes of the Supreme Court. The 9th Circuit is continually siding against police on almost every issue but they cannot be sued. Must be nice to have that type of immunity when you are so frequently wrong!

Try pulling this BS in Germany or Israel and see how far an illegal aliens gets. When IED's end up in the streets of a major city will the 9th Circuit and the liberal folks look at it from a different perspective? I sure hope so. I see us american citzens as weak towards all other cultures in this world except for the Native American Indian who really got the screws put to them.
