NYT Does Encryption and the 5th Amendment

Adam Liptak, who has been on a roll lately, has another great “Sidebar” in today's NYT entitled, If Your Hard Drive Could Testify …. The article quotes me and Orin Kerr as if we were opposed; oddly, although I think Orin and I do have disagreements about what the law on encryption should be, I suspect Orin and I agree with each other on the points for which we're actually quoted.

Although the article does a great job of describing some recent cases and issues, the academic in me wishes that every time anyone writes about this stuff they'd have the space and time to provide what I see as some critical context for the debate as to when a person can be forced to hand over the key to a cryptosystem.

There are plenty of technical issues here (what happens if you really have forgotten your password? or if someone has put random gunk on your hard drive, making it look like there's crypto there?), but even more important fundamental ones. In particular, the current debate over the extent to which the 5th Amendment protects encrypted messages matters so much because our understanding of the 4th Amendment has changed. A hundred years ago, the Supreme Court thought it was obvious that asking a person to turn over his private papers was a constitutional violation. Even 30 years ago the Court thought that the 4th Amendment protected some zone of private papers such as a diary from demands that they be turned over. (Note that there can be an important difference between finding something in a search and demanding that the subject of the search find it for you.) Today, although the Supreme Court has never actually decided the diary issue, it's pretty clear that no other writing — and probably not the diary either — is protected from such demands.

It's the evisceration of the 4th that puts such pressure on the 5th. It may be that as a society we really don't want to allow any zone of privacy beyond what you can keep in your head. But as devices record more of our lives, and as we rely increasingly on what some of us only half-jokingly call our prosthetic memories, I think that it is increasingly unrealistic to exclude at least some bits from the intimate zone of privacy if we wish to remain true to the purposes of the 5th (and 4th) Amendments.

Coral Gables’s Mysterious Nativity Scene

This elaborate nativity scene is prominently displayed in downtown Coral Gables near the corner of Ponce De Leon and Alhambra, on a little circle of land that might be public, or might be an amenity belonging to a nearby office building. It has no sign on it saying who erected it or how it got to be there.

Google Maps actually has a good image of it:

I've never taught or litigated an Establishment Clause case, but I was under the impression that if this is public land, there has to be a sign on such a display explaining who paid for it, lest it appear to be a city-purchased religious display. Then again, it might be private land. Indeed, one of my colleagues tells me that there used to be a church where the building next to the circle now stands (the tall thin building in the image above), and speculates that when they sold the land they held on to this piece (or kept an easement) just for this purpose. Could be: but why no sign claiming credit?

Passphrases and the Fifth Amendment

Declan has the scoop, Judge: Man can't be forced to divulge encryption passphrase:

A federal judge in Vermont has ruled that prosecutors can't force a criminal defendant accused of having illegal images on his hard drive to divulge his PGP (Pretty Good Privacy) passphrase.

U.S. Magistrate Judge Jerome Niedermeier ruled that a man charged with transporting child pornography on his laptop across the Canadian border has a Fifth Amendment right not to turn over the passphrase to prosecutors. The Fifth Amendment protects the right to avoid self-incrimination.

Niedermeier tossed out a grand jury's subpoena that directed Sebastien Boucher to provide “any passwords” used with his Alienware laptop. “Compelling Boucher to enter the password forces him to produce evidence that could be used to incriminate him,” the judge wrote in an order dated November 29 that went unnoticed until this week. “Producing the password, as if it were a key to a locked container, forces Boucher to produce the contents of his laptop.”

Full text of the decision in In Re Boucher, 2007 WL 4246473 (D. Vermont, Nov. 29, 2009).

Long ago I wrote a lot about encryption keys, and touched on this issue. You can read the articles at The Metaphor is the Key: Cryptography, the Clipper Chip and the Constitution, 143 U. Penn. L. Rev. 709 (1995) and especially It Came From Planet Clipper, 1996 U. Chi. L. Forum 15.

The heart of the argument is that things in your head are not like objects in your possession: the core value of the Fifth Amendment is that you can’t be made to speak in ways that indicate your guilt. Giving up a passphrase to an encrypted message ties you to the encrypted information; if the info is, say, child porn, it creates a very strong inference that you knew what the data were and that you possessed them (there are exceptions, including email some else sent to you that is decryptable with you private key, but ignore those scenarios for now).

Other people, notably the redoubtable Orin Kerr, who argue that there is no Fifth Amendment issue here tend to focus on the analogy of possession of a physical key to a physical lock. The law is pretty clear that you can’t stop the cops from taking a physical key on the grounds that the stuff inside that safe will tend to incriminate you.

But the law is also clear that the Fifth Amendment protects you from having to make an oral or written disclosure which is “testimonial” – that, is, whose content might tend to tie you to crime. (Note that “content” means “informational content” – you can be forced to give a meaningless writing sample for handwriting comparison purposes.) This is why the cops are not able to force suspects to take them to the dead body.

It seems to me that the pure compelled disclosure case is not that hard, and that this Magistrate Judge got it right. Note, however, that this decision, emanating from the lowest-level official in the federal court system, is not precedential for other courts; and since it is pretty brief its persuasive power may not be all that great either.

Nor do I think that making a defendant decrypt something without divulging the key would in any way solve the problem, as it still ties the defendant to the content.

The hard case for me would be if the police provided limited “use immunity”: they would promise not to make the fact that your key decrypted the info any part of the prosecution. Thus, for example, the indictment would just say the information was on your hard drive, without mentioning that you had the only key to decrypt it. I think, given the current state of doctrine, that courts might well hold this to be consistent with the Fifth Amendment, making the underlying provision little more than a fairly cumbersome technicality. Doctrinally, that is not such a hard result to foresee, but it is not as simple to explain why this would apply to a coded message and not a dead body.

The flip side of the hard case is when the government provides use immunity and the suspect/defendant claims he doesn't know or has forgotten the passphrase. Then what?

In fact, I do have one ancient PGP key for which I seem to have forgotten the passphrase, so I know it can happen. But in most cases the police are likely to view this sort of memory malfunction as unduly convenient.

Congress Rediscovers the Power of the Purse

Secrecy News, Intelligence Oversight Flexes One New Muscle, is sort of a good-news, bad-news item.

The good news is that the Senate Intelligence Committee has reported out language that makes expenditures conditional on every member of the committee being briefed on a specific intelligence issue.

The bad news is that the committee apparently wasn't able to figure this out for itself: it had to have the idea explained to it by by former Rep. Lee Hamilton.

If I had any boggle left in my mind this week, that would use it up.

Senators and Representatives Could Have Spoken Out On Waterboarding: the Constitution Protects Their Right to Speak Out Without Fear of Legal Consequences

A number of the best internet commentators are discussing today’s news that a few of the leading Congressional Democrats may have been – probably were – briefed about the administration’s plans to torture (waterboard, and maybe more) suspected terrorists being held in secret CIA facilities abroad. There’s confusion about the facts, with few of the people allegedly briefed confirming the story. Notably, however, it appears that of those briefed, only Rep. Jane Harman objected. (Note that we’re still at an early spin stage here — more facts about who said what to whom are likely to come out.)

The emerging consensus in the blogosphere seems to be that even if they had the presence of mind to object, the Representatives and Senators who were briefed were in a bind: as members of the Intelligence Committees or the leadership, they signed various secrecy pledges which stopped them from going public. To go public, it seems to be agreed, was to “jeopardize their careers and risk jail” as Kevin Drum put it; even so, Matthew Yglesias suggests that this called for civil disobedience, and that the representatives should have dared the administration to arrest them.

All this misses a critical aspect of our constitutional structure. Thanks to the Speech and Debate Clause there was a way for any Senator or Representative who wanted to blow the whistle to do so in a way that involved no risk of jail or fines – at worst they might have lost their security clearances (and even there the law is a little murky).

Article I, section 6 of the Constitution reads as follows,

The Senators and Representatives shall receive a Compensation for their Services, to be ascertained by Law, and paid out of the Treasury of the United States. They shall in all Cases, except Treason, Felony and Breach of the Peace, be privileged from Arrest during their Attendance at the Session of their respective Houses, and in going to and returning from the same; and for any Speech or Debate in either House, they shall not be questioned in any other Place.

No Senator or Representative shall, during the Time for which he was elected, be appointed to any civil Office under the Authority of the United States, which shall have been created, or the Emoluments whereof shall have been encreased during such time; and no Person holding any Office under the United States, shall be a Member of either House during his Continuance in Office.

(emphasis added)

The Speech and Debate clause has been interpreted to extend beyond floor speeches, e.g. to committee statements, but it unquestionably applies to floor statements. Thus, it would have been possible for Rep. Harman, or Senator Rockefeller, or the others allegedly briefed to go to the floor, either during the times when members may speak on topics of their choice, or under one of the extraordinary mechanism for privileged statements, and denounce the Bush administration’s determinate to torture helpless captives in secret offshore detention facilities.

I’m not saying this would be easy or politically painless. The political risks are obvious – and recall the Congress was being briefed not all that long after 9/11. But even without the national security angle or the political frenzy angle, there were also counterveilling issues of fundamental personal ethics As Rep. Harman noted,

“When you serve on intelligence committee you sign a second oath — one of secrecy,” she said. “I was briefed, but the information was closely held to just the Gang of Four. I was not free to disclose anything.”

Serious people take oaths like this seriously and are right to do so; but before they took that second oath, they took a first one upon taking office in which they promised to “preserve and defend the Constitution of the United States.” To the extent that the second oath allows the executive to muzzle members of Congress, it is unconstitutional under any theory, including not only the Speech and Debate clause, but also the Incompatibility Clause (which forbids members of congress from serving in the executive branch; a converse conclusion is that this clause forbids the executive branch from turning members of Congress into subordinates).

Although apparently too easily forgotten, the Speech and Debate Clause is, as Justice Harlan said in United States v. Johnson, 383 U.S. 169, 178 (1966),

the culmination of a long struggle for parliamentary supremacy. Behind these simple phrases lies a history of conflict between the Commons and the Tudor and Stuart monarchs during which successive monarchs utilized the criminal and civil law to suppress and intimidate critical legislators. Since the Glorious Revolution in Britain, and throughout United States history, the privilege has been recognized as an important protection of the independence and integrity of the legislature.

The Supreme Court has limited the reach of the Speech and Debate Clause in some relevant respects. In Doe v. McMillan, 412 U.S. 306 (1973), the Court distinguished statements on the floor (or in committee) – which are and remain completely privileged – and their republication elsewhere. In that case a committee print of one of its reports, issued in a routine manner by the Public Printer, contained allegedly defamatory statements about private citizens. They sued for an injunction to prevent further publication, dissemination, and distribution of the report until the objectionable material was deleted, and sought damages. The Court held that the Members of Congress and their staffs could not be sued due to the Speech and Debate Clause, since their actions had all been part of the ordinary legislative process. But the Court also held the Superintendent of Documents and the Public Printer could be sued because they had no broader immunity than Members of Congress would have and their actions in publically disseminating the report outside Congress were not legislative acts, unlike voting, speaking on the floor or in committee, which are protected.

More troubling for third parties, however, is Gravel v. United States, 408 U.S. 606 (1972). Senator Gravel read key parts of the Pentagon Papers at a committee hearing, and then placed the full text of the 47 volumes of it into the public record. That act, the Supreme Court held, was privileged, an argument it called “incontrovertible.” But the Court refused to assume that once the material was in the public record it automatically followed that arrangements to republish them were inevitably legal, nor did at accept that Senator Gravel’s attempts to find a publisher (or his aide’s, which they took to be the same thing for these purposes), fell under the Speech and Debate Clause.

Combine this holding with the administration’s more recent and aggressive re-interpretations of the Espionage Act, which seek to extend it to reach the conduct of parties not holding clearances who share information that they acquire from someone who has one, and you begin to wonder whether newspapers that republished the floor speech might not face some legal attacks from the Justice Department. Although I personally think that the First Amendment must protect a newspaper that republishes a member of Congress’s statements on the floor, it is clear that the current administration has taken positions that would allow it to argue the contrary; more to the point, although I think the newspapers would win such a case, even the main Pentagon Papers case, much less the Gravel case noted above, don’t conclusively foreclose the government from arguing the contrary.

The question of security clearances is the murkiest part of the story. The Bush administration has consistently taken the extreme position that it never has any legal duty to tell Congress anything. It claims the power to ignore subpoenas. It says that the President is the only judge of what he has to do, and any attempt to compel him is unconstitutional. As early as 2001 the administration unilaterally revoked the security clearances of 91 Senators, arguing as GW Bush put it “it’s not in the nation’s interest” that they have access to information they could leak.

I believe that Congress could Constitutionally legislate to preserve the security clearances of members who disclose classified information on the floor. As far as I know (please correct me if I’m wrong), Congress has never passed such a rule, and in its absence, I think it is within the power of the executive to choose to deny clearances to whistle blowing members of Congress. That is a forward-looking loss of privilege rather than a legal disability of the sort that the Speech and Debate Clause protects against. But legally, that’s it. A member of Congress who learned of torture plans and chose to tell the nation about them would face no other legitimate legal risk; (there was, with the Gonzales gang, the not inconsiderable possibility of an improper prosecution, but many of the key events here were when Ashcroft was Attorney General) .

It would have taken great courage, and carried political risk, but our Constitution does provide a channel by which members of Congress can stand up and call the executive to account on its plans to torture someone in a secret CIA prison. At the end of the day it was that courage, not the legal avenue to expose wrongdoing, which was in too short supply in Congress.

(I’ve written the above in something of a hurry and think of it as a very preliminary attempt to explain the role of the Speech and Debate clause. I welcome correction and amplification from those who may know more than I; I would be particularly grateful for any insights regarding the granting and withholding of security clearances for members of Congress, a subject I am sure I have much to learn about.)

Senator Biden Ought to Read the Constitution

My brother's column today, Is Bush Ready to Talk Pullout?, contains the following pointer:

Adam Leech writes in the Portsmouth (Maine) Herald: “Presidential hopeful Delaware Sen. Joe Biden stated unequivocally that he will move to impeach President Bush if he bombs Iran without Congressional approval.

“Biden spoke in front of a crowd of approximately 100 at a Seacoast Media Group forum Thursday, which focused on the Iraq War and foreign policy. When an audience member expressed fear of another war with Iran, he said he does not typically engage in threats, but had no qualms about issuing a direct warning to the oval office.

“'The President has no authority to unilaterally attack Iran and if he does, as foreign relations committee chairman, I will move to impeach,' said Biden, which was followed by a raucous applause.

“Biden said he is in the process of meeting with constitutional law experts to prepare a legal memorandum saying as much, and intends to send it to the President.”

Small problem. The Senate doesn't initiate impeachments. Those have to come from the House of Representatives; the Senate's role is then to judge the merits of the impeachment.

Art. I, Sec. 2, Clause 5: The House of Representatives shall chuse their Speaker and other Officers; and shall have the sole Power of Impeachment.

Art. I, Sec. 3, Clause 6: The Senate shall have the sole Power to try all Impeachments. When sitting for that Purpose, they shall be on Oath or Affirmation. When the President of the United States is tried, the Chief Justice shall preside: And no Person shall be convicted without the Concurrence of two thirds of the Members present.

Doesn't Biden — a long-serving Senator, and veteran of impeachment trials — know that by now? Was he misquoted, or is he stupid, or does he think we are?
