On April 29, 2010, Arizona Governor Jan Brewer signed into law SB 1070, which gave local authorities sweeping powers to detain suspected illegal immigrants.
The legal issue at question is taken directly from Article VI, Paragraph 2 of the Constitution, commonly called the Supremacy Clause:
This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any state to the Contrary notwithstanding.
The principle which arises out of this paragraph is called preëmption. Preëmption can be express (i.e. explicit, stated clearly) or implied. The basic question for the Court, in oral arguments today, will be: does SB 1070 run afoul of the Supremacy Clause?
Article I Section 8 of the United States Constitution gives Congress the authority to regulate naturalization, that is, explicitly preëmpts state law on the matter:
The Congress shall have Power To … establish an uniform Rule of Naturalization …
It’s not a huge cognitive leap to imagine that naturalization rules and immigration policies are in the same realm.
Arizona (ironically then led by Governor Janet Napolitano who is now the Secretary of Homeland Security with authority over immigration policy) declared an emergency surrounding immigration in 2005. In a double irony, a report today by the Pew Hispanic Center says that net immigration into the United States from Mexico has been near-zero in the 2005 to 2010 period. That is, 1.4 million Mexicans immigrated to the U.S. during that period, while 1.4 million Mexicans emigrated back to Mexico during the same period. This is presumably due to the Great Recession of 2008. Is the timing of this report a coincidence, on the eve of oral arguments before the Court? It’s hard to believe it could be.

Gold Hat: “We are Federales… you know, the mounted police.” Dobbs: “If you’re the police, where are your badges?”
There are four disputed parts to SB 1070:
- Law enforcement is required to determine an individual’s immigration status upon any contact, or if they even suspect someone is an illegal immigrant (see #4 below). [This is section 2b of the law.]
- It is a violation of Arizona state law to fail to register as an alien. [Section 3]
- Illegal aliens are not allowed to find work under Arizona law. [Section 5c]
- Arizona police have the power to make warrantless arrests of those suspected to be in violation of Federal immigration law. [Section 6]
A partially divided Ninth Circuit Court has ruled that these four provisions of SB 1070 fall under the principle of preëmption and are therefore unconstitutional.
Under long-standing policy, Congress allows the states to coöperate with the Federal government to enforce Federal immigration laws. Bill author Russell Pearce (who has since been recalled by voters) was among those spewing partisan rhetoric and thumbing their noses at the Federales, claiming they don’ need no stinkin’ badges.
This ought to be a no-brainer for the courts. I hope the appeals court allows our state to enforce the rule of law because the Obama administration doesn’t seem to care one whit for the safety of the citizens of Arizona. SB 1070 simply reflects federal immigration law. This Obama team doesn’t want immigration laws enforced — but that doesn’t mean that Arizona can’t take common sense steps to protect its own citizens. This is the first time in the history of this Republic, that a sitting President has sided with a foreign government against our citizens and in fact sued them to prevent them from enforcing the laws of the land.
Now counsel for Arizona will argue before the Court that Arizona legislators only intended to help out the United States, in the required spirit of coöperation evident in the above quote.
Over at SCOTUSblog, Stephen Wermiel writes:
Coöperation did not seem to be Arizona’s main motivation in passing the law. When Governor Jan Brewer signed the legislation, known as S.B. 1070, in April 2010, she described it as “another tool for our state to use as we work to solve a crisis we did not create and the federal government has refused to fix.” Alabama, which recently passed a more restrictive immigration law, has defended its action in lower federal court proceedings on the basis of a need to stem the tide of unlawful aliens. In seeking Supreme Court review, however, Arizona now argues that its law is an effort to coöperate with federal enforcement.
Gabriel Chin, a professor of immigration law, firmly believes that SB 1070 will be struck down by the Supreme Court.
Every lower court to look at these types of statutes in Alabama, South Carolina, Utah and Arizona has said they’re unconstitutional. As a sort of plain vanilla constitutional analysis question, if you look at the old cases, if you look at the statute, it’s pretty clear that Congress is in charge here. The federal government is in charge here.
…
These whole problems came up before. They came up in the 1870s in California, when California wanted to drive out the Chinese. And the basic law was established by the U.S. Supreme Court and by Congress, then. And the idea is that these laws should be established and carried out by Congress.
Here’s what the Supreme Court said in 1876. The responsibility for the character of those regulations and for the manner of their execution belongs solely to the national government. If it be otherwise, a single state can, at her pleasure, embroil us in disastrous quarrels with other nations.
Chin is arguing, as other experts have, for the doctrine of express preëmption in this case. Despite the heated arguments on this issue, it appears unlikely that the Supreme Court will find any Constitutional grounds to support Arizona SB 1070.

I realize this isn’t part of the case, but I’m particularly troubled by the wording in 1070 that allows officers to be sued for inadequately enforcing that law. They are, then, in the position of being liable for not arresting someone, and simultaneously liable for arresting that same someone, simply because the officer is forced to make a determination based on insufficient information. It’s a needle they shouldn’t have to thread.
In any case, I’m curious to see how Scalia handles this case. The conservative Tenther side of him surely wants to side with Arizona. But surely he recognizes that we can’t have 51 different foreign policies. How will he thread that needle?
Anyone know how many states Bush sued in his 8 years? Liberals certainly are going after the states.
Partisan ideologues are unconcerned with practicality or reality. Their concern is with making The Other Guy look bad.
But surely he recognizes that we can’t have 51 different foreign policies. How will he thread that needle?
Seems very easy. If a state apprehends a terrorist…are the deemed to “have their own terror policy”? Not sure how “coördination with the Feds” turns into “overriding the Feds”. It honestly seems like a trivial case—should be a slam dunk for AZ.
FYI on the same subject: In September 2007, the Bush administration sued the state of Illinois, seeking to have an Illinois immigration statute declared unconstitutional under the Supremacy Clause of the U.S. Constitution.
rgbact, use the Google if you want an exact count and let us know.
rgbact,
Bush sued Illinois. Why? Because he didn’t want Illinois to preëmpt federal law on immigration. Hmmm…
Well, now that the arguing is over, I now understand that Scalia has no interest in threading the needle. He actively supports having 51 foreign policies. Fortunately, he’s alone among the nine.
rgbact,
No. But if a state passes a law requiring apprehension of terrorists, then they are.
Here’s why it’s different. Let’s assume for the sake of argument that Arizona’s law precisely mirrors federal law. What happens when federal law changes? The Arizona law then is no longer in sync with the federal law. And there’s no provision for 1070 to automatically change to remain in sync with federal law.
Why? Because he didn’t want Illinois to preëmpt federal law on immigration. Hmmm…
Looks like IL was banning the federal system. My understanding is that AZ is just helping enforce the federal system. That seems like a huge difference,
rgbact,
How about if a gang of rabble rousers decides to enforce immigration policy on its own? Is it okay to assemble a vigilante mob posse? Since states don’t have the legal authority to enforce federal law without the permission of Congress, how does Arizona’s action differ from that of an anarchist mob? And why shouldn’t the members of the Arizona state legislature be thrown in federal prison?
@Michael
The possibility that officers could be sued for inadequate enforcement also troubles me, because who gets to determine what “adequate” enforcement is? How are they going to decide who is a “likely” illegal immigrant? By looks? By clothes? By language? Will the officer be sued if he doesn’t stop every Hispanic-looking person that he meets? What about all of the illegal Canadians? How could the officer adequately enforce the law if he doesn’t stop every single person? Or does he only have to demand papers of a Caucasian if they say “aboot” or “eh”? The AZ statute effectively requires all Americans visiting or living in AZ to carry papers proving their citizenship or risk being subjected to detainment. And that’s about as un–American as anything I can imagine.
Officer: “Please show documentation that you are legitimately here in this country.“
Citizen: “What?“
Officer: “I need to see your papers.“
Citizen: “What papers? I’m an American.“
Officer: “Prove it.“
Citizen: “Prove it? This is a free country. As an American, I don’t have to prove that.“
Officer: “If you can’t prove it then I have to arrest you and detain you until you provide sufficient documentation establishing your right to residency. If you can’t prove that you belong here, then we’ll deport you to the country of our choice.”
mclever,
It does kind of come down to that. If you’re a citizen and speak with a foreign accent, and you’d better carry your citizenship papers with you at all times.
BTW, I was once asked by INS if I was a US citizen. I looked at him like he was crazy before I responded. I can’t be in any foreign country without being obviously American, no matter how hard I try to blend in. But the fact is, if the INS guy had demanded proof of my citizenship, I would have been out of luck. I had none.
Should this law be upheld, any legal Hispanic from California must avoid being in Arizona at all costs, unless that person is also carrying a birth certificate, citizenship certificate, or passport. A California driver’s license is not acceptable as proof of citizenship in Arizona.
Michael,
Funny that you’d get questioned by INS. I’ve been mistaken for both British and German while traveling abroad, of course neither while I was actually in England or Germany. Outside the USA, I’m pretty obviously foreign, but apparently I don’t always give off a scary American vibe. Here in the USA, I was once asked if I was Canadian, but not by anyone in an official capacity. Kinda funny, eh?
The point remains that US citizens aren’t supposed to have to carry or provide any proof of their citizenship or residency while in the United States. That’s the whole point of this being a free country. Frankly, I’m shocked that anyone who would consider themselves marginally Libertarian (as many conservatives do) would see it any differently. Or, maybe it’s only because they can’t imagine themselves ever being stopped, and it’s all OK as long as it happens to those people.
Looks like another rough day in court for the Obama team.
From NBC:
Based on comments during Wednesday’s oral arguments on the case, even some of the court’s liberal justices seemed to find no strong objection to the most controversial part of the law, which requires local police to check on the immigration status of anyone they detain or arrest.
rgbact posted an NBC article:
I disagree that this provision (section 2b) is the most controversial part of the law. Not even the most ardent civil libertarians, in my experience, have a problem with the police running “wants and warrants” on you if you are legitimately arrested.
If you look at the above discussion, what scares people the most is section 6, which provides — demands — warrantless arrest of anyone suspected of being too brown.
I would trust Lyle Denniston’s SCOTUSblog analysis of the case more than MSNBC’s. This is a much more nuanced and accurate view, I think.
I would also note that MSNBC has modified the section rgbact quotes above. The new lede is much more nuanced and accurate:
Also note that with former Solicitor General Kagan recused, and with the Ninth Circuit ruling against Arizona, that Arizona needs a 5–3 vote to prevail.
Good points, Monotreme.
It’s important to remember that the SC decision on the question currently before it won’t answer for all time whether the AZ law is Constitutional or not, because they’re only considering whether it’s stepping on Federal toes by creating a separate or independent immigration policy. The question is all about preemption.
So, if I understand the situation, the Court could rule now that the AZ law doesn’t violate the preemption clause, but later a US Citizen could bring suit for having been detained, and the law could be ruled un-Constitutional on those grounds, because the police can’t detain citizens without cause. Or a class-action suit could be brought by a group of brown-skinned citizens who all got stopped for no other apparent reason. Or perhaps a police officer sued for failing to enforce it thoroughly enough for some racist resident could appeal the suit up through the courts, etc.
As is so often the case, this may be an instance of Solomonic baby-splitting. On one hand, people who are here illegally should be found and deported. On the other hand, finding and deporting those who are here illegally should not subject a much larger population of legal residents to undue curtailment of daily activities.
27% of Arizona’s residents are Hispanics who are legal residents. More than one in four. If you add in the Native American population (who is to many indistinguishable from Hispanic), you get an additional 6%. This means that one in three legal Arizonans “look illegal”.
The likelihood of false positives is huge in that environment.
Whatever system we develop to find and deport illegal residents, it shouldn’t be crafted in such a manner as to subject a third of the legal population to random, lengthy, unwarranted incarceration. But that’s what 1070 necessarily does.
Arizona, New Mexico, and Colorado may be in play in the Presidential election in November, thanks to AZ 1070. Florida and Virginia are increasingly winnable for President Obama. It’s a gift to the Democrats.
Romney cannot distance himself from the desire to side with bigots against Hispanics and Latinos. The ads write themselves — and might not need ever to be aired.
The guy who co-authored AZ 1070 today admitted the purpose of the law was to maximize America’s white population.
Learn about Russel Pierce here.
Let’s see Romney walk that back.
Arizona, New Mexico, and Colorado may be in play in the Presidential election in November, thanks to AZ 1070.
If PPACA is overturned and 1070 is upheld.…Obama can have those states
I’m actually more interested in how this effects the down ballot races. Chuck Shumer has a plan to put this issue to a vote if 1070 is upheld, so we’ll see how senators and candidates in the toss-up states come down on this. If DC is right, all the Senate Dems should be drooling at the chance to vote against 1070.
It never ceases to amaze me when folks, most of whom can’t even name eight of the nine justices, assume they know the decision the SCOTUS will make based on the questions asked during orals.
It’s worse when they expound on the case in a manner that demonstrates that they don’t understand what is at issue in the case before the SCOTUS and the possible outcomes that will be decided.
Take FAA v Cooper. The SCOTUS decided in favor of the FAA. Does that mean the FAA has won the suit filed against it by Cooper?
No. The SCOTUS decided ONLY the question of violation of the Privacy Act of 1974, as pertaining. The lawsuit has never even been heard! The SCOTUS case was over the Motions for Summary Judgement filed with the judge at the beginning. That suit may now go forward, but Cooper cannot hide behind the Privacy Act. From a practical standpoint, this may well make Cooper’s case moot. I’ve not read his original Complaint, and there well may be other matters at issue such that may allow him to move forward, or he may filed an Amended Complaint. We’ll see.
rgbact,
Such is the reasoning of many on the right on the prospects of the future of the GOP. And it is pure denial. Denial of the changing demographics in this country. The browning of America.
Because it AIN’T just “those states”. It’s also Florida, North Carolina and Virginia. And that’s just in the short term! What happens when those states, now we’re up to SIX, become reliably blue? Do you want to give away all THOSE electoral votes? Because, even when you give Ohio, Iowa, Pennsylvania and New Hampshire to the GOP, those six, added to the current leans Democratic or better, adds up to 310 EV!
And not counting those latter three, if they all go red, the Democrats taking only Ohio will put them over 270.
Be very careful in what you ask for.
Max,
According to the Republicans, the “real America” is white anyway.
Agreed, Max. I think everyone assumed that Toobin’s read of the Justices’ questions during orals on PPACA is some sort of special wisdom. I think he’s going to end up with egg on his face.
I don’t presume to know how the Justices will decide PPACA or Arizona or, for that matter, FAA v Cooper. That’s what I think is fascinating about writing up these Supreme Court Watch pieces.
I do think the history of the Roberts Court is to decide on very narrow technical grounds, and I think that the one thing we can get out of orals in this case is that Roberts clearly signaled the world and his colleagues that it’s going to be a very very narrow decision.
What happens when those states, now we’re up to SIX, become reliably blue
Go reread my immigration article from a few months back about the “browning” myth. Here’s a recent article that basically backs up what I had written.
http://decoded.nationaljournal.com/2012/04/rethinking-the-hispanic-vote.php
And heres the money shot
“Indeed, a complementary Pew Hispanic Center study, released last month, showed immigrants becoming more Republican the longer they’ve been in this country — a similar narrative to other first-generation ethnic groups”
Agreed, Max. I think everyone assumed that Toobin’s read of the Justices’ questions during orals on PPACA is some sort of special wisdom.“
I agree. That why I said I would give up states EV’s for the rulings. But I’m surprised people assume PPACA is dead because of some tough questioning. I’d say 1070 will be hard to overturn though. I’ll put PPACA at 50⁄50 and 1070 at 90%.
rgbact,
I don’t think that you understand that there are SEVERAL parts of 1070 at issue before the SCOTUS? (As is the case of PPACA) That their decision will not be all or nothing? If not, please go back and look at the bigger picture.
How do you call the various PARTS of 1070 before the Court.
Yes, I read it back then. And nothing changes, IMHO. The reality of the past several presidential elections and the Hispanic vote tell a different empirical tale. I’d rather go with the facts versus a good theory.
Max, in other words, rgbact is hoping’/prayin’ Hispanics don’t become the majority voting block in America anytime soon.
Again, as older white folk continue to pass on to teabagger heaven …
So it shall be written, so it shall be done. Praise the Lord!
Republicans = short term imaginary gain vs. big political picture as they can’t see the forest for the trees because of inate bigotry/prejudice. As per usual.
