The IRS Believes All Bitcoin Users are Tax Cheats

The Internal Revenue Service has filed a “John Doe” summons seeking to require U.S. Bitcoin exchange Coinbase to turn over records about every transaction of every user from 2013 to 2015. That demand is shocking in sweep, and it includes: “complete user profile, history of changes to user profile from account inception, complete user preferences, complete user security settings and history (including confirmed devices and account activity), complete user payment methods, and any other information related to the funding sources for the account/wallet/vault, regardless of date.” And every single transaction:

All records of account/wallet/vault activity including transaction logs or other records identifying the date, amount, and type of transaction (purchase/sale/exchange), the post transaction balance, the names or other identifiers of counterparties to the transaction; requests or instructions to send or receive bitcoin; and, where counterparties transact through their own Coinbase accounts/wallets/vaults, all available information identifying the users of such accounts and their contact information.

The demand is not limited to owners of large amounts of Bitcoin or to those who have transacted in large amounts. Everything about everyone.

Communications and Data Meet the Fourth Amendment

This week and last, the Cato Institute filed amicus briefs urging the Supreme Court to take up two cases dealing with the constitutional status of “cell site location information,” or “CSLI.” This data, collected of necessity by cellular communications providers, creates detailed records of their customers’ movements. The briefs invite the Court to accept these cases so it can revise Fourth Amendment practice to eschew doctrine and more closely adhere to the language of the Fourth Amendment.

The Fourth Amendment states that “[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated.” Presumably, when called upon to determine whether a Fourth Amendment violation has occurred, courts would analyze the elements of this language as follows: Was there a search? Was there a seizure? Was any such search or seizure of “their persons, houses, papers, [or] effects”? Was any such search or seizure reasonable?

And in cases involving familiar physical objects, courts usually do a sound textual analysis, at least implicitly. But in harder cases dealing with unfamiliar items such as communications and data, courts retreat to “reasonable expectation of privacy” doctrine that emerged from Katz v. United States in 1967, and offshoots of it like the “third-party doctrine.” The “reasonable expectation of privacy” test asks whether defendants’ feelings about things government agents accessed were reasonable. The corollary “third-party doctrine” cancels Fourth Amendment interests in information and things that are shared on the theory that expectations of privacy evaporate in that context.

The “reasonable expectation of privacy” test is the product of one non-essential concurrence in Katz, and the third-party doctrine was wrong when the Supreme Court created it in 1976 to ratify a law that deputized banks into financial surveillance. That doctrine grows further out of synch with each step forward our society takes in modern, connected living. Today, third-party service providers collect incredibly deep reservoirs of information about us: Cellular telephone networks, Internet service providers, search engines, and payment systems have data that can throw open windows onto our relationships, feelings, health conditions, business dealings, sexuality, emotions, and more.

The Weird World of Data (and Your Privacy)

In 2007, Judge Richard Posner found it “untenable” that attaching a tracking device to a car is a seizure. But the Supreme Court struck down warrantless attachment of a GPS device to a car on that basis in 2012. Putting a tracking device on a car makes use of it without the owner’s permission, and it deprives the owner of the right to exclude others from the car.

The weird world of data requires us to recognize seizures when government agents take any of our property rights, including the right to use and the right to exclude others. There’s more to property than the right to possession.

In an amicus brief filed with the U.S. Court of Appeals for the D.C. Circuit last week, we argued for Fourth Amendment protection of property rights in data. Recognition of such rights is essential if the protections of the Fourth Amendment are going to make it into the Information Age.

The case arises because the government seized data about the movements of a criminal suspect from his cell phone provider. The government argues that it can do so under the Stored Communications Act, which requires the government to provide “specific and articulable facts showing that there are reasonable grounds to believe that [data] are relevant and material to an ongoing criminal investigation.” That’s a lower standard than the probable cause standard of the Fourth Amendment.

As we all do, the defendant had a contract with his cell phone provider that required it to share data with others only based on “lawful” or “valid” legal processes. The better reading of that industry-standard contract language is that it gives telecom customers their full right to exclude others from data about them. If you want to take data about us that telecom companies hold for us under contract, you have to get a warrant.

The Fourth Amendment Protects Your Cell-Location Data

When the federal district court in D.C. ordered a seizure of Alonzo Marlow’s cell service location information (CSLI) held by his cell provider, it held that the federal government didn’t need a warrant to obtain CSLI data from a person’s phone provider. The Stored Communications Act of 1986 (SCA) governs the searching of such data, and under § 2703(d) of that act, federal investigators need not demonstrate probable cause in order to search—but merely to show “specific and articulable facts” that there is criminal wrongdoing. Thus, the Fourth Amendment requirement that “no warrants shall issue, but upon probable cause” is effectively removed.

Understanding U.S. v. Ackerman

The Supreme Court has eschewed the “reasonable expectation of privacy” test in its most important recent Fourth Amendment cases. It’s not certain that the trend away from the so-called “Katz test,” largely driven by Justice Scalia, will continue, and nobody knows what will replace it. But doctrinal shift is in the air. Courts are searching for new and better ways to administer the Fourth Amendment.

A good example is the Tenth Circuit’s decision last week in U.S. v. Ackerman. That court found that opening an email file was a Fourth Amendment “search,” both as a matter of reasonable expectations doctrine and the “distinct line of authority” that is emerging from the Supreme Court’s 2012 decision in U.S. v. Jones.

Here are the facts: AOL scans outgoing emails for child porn by comparing hashes of files sent through its network to hashes of known child porn. When it becomes aware of child porn, it is required by law to report them to the National Center for Missing and Exploited Children. NCMEC is a governmental entity and agent. (That point takes up the bulk of the decision; Congress has made huge grants of governmental power to the organization.) NCMEC opened the file without a warrant.

Economics Will Be Our Ruination II

Economics appears to be a neutral tool, but it often subtly embeds values that we are better off surfacing and discussing. In a recent post henceforth to be known as “Economics Will Be Our Runiation I,” I pointed out how, by preferring to measure the movement of dollars, orthodox economics treats leisure as a bad thing and laments advances in technology-based entertainments.

This installment of EWBOR focuses on an interesting and insightful article recently published in the University of Pennsylvania Law Review, “An Economic Understanding of Search and Seizure Law.” In it, George Washington University Law School professor Orin Kerr shows that the Fourth Amendment helps increase the efficiency of law enforcement by accounting for external costs of investigations. Here is his model:

The net benefit of any particular investigative step can be described as P*V – Ci – Ce, where P represents the increase in probability that the crime will be solved and successfully prosecuted, V represents the net value of a successful prosecution resulting from deterrence and incapacitation, Ci represents the internal costs of the investigative step, and Ce represents its external costs.

Ci means things like the cost of training and equipping police officers and paying their salaries, as well as their own use of their time. Ce, external costs, “include privacy harms and property losses that result from an investigation that is imposed on a suspect. They also include the loss of autonomy and freedom imposed directly on the subject of the investigation (who may be guilty or innocent) as well as his family or associates.” Kerr rightly includes in Ce more diffuse burdens such as community hostility to law enforcement.

Patel: Right Result, Wan Rationale

Making short work of the idea that facial challenges aren’t available under the Fourth Amendment, the Supreme Court ruled today in Los Angeles v. Patel that a city may not require its hotels to turn over their business records without some opportunity for review of the government’s demands. It’s the right result, but the Court was too quiet about its treatment of Fourth Amendment doctrine, and it did not take the opportunity to fully address situations like the case presented, in which the government dragoons private businesses into surveillance on its behalf.

Justice Sotomayor, writing for a 5-4 majority, held: “the provision of the Los Angeles Municipal Code that requires hotel operators to make their registries available to the police on demand is facially unconstitutional because it penalizes them for declining to turn over their records without affording them any opportunity for pre-compliance review.” Justice Scalia led one bloc of dissenters believing it was reasonable to institute this kind of regulation on business owners suspected of no substantive crime because their facilities are sometimes used for crime. Justice Alito dissented as well, arguing that there should be no facial challenge to the statute because constitutional applications of it exist.

Had the stars lined up, the Court might have used the Patel case to address simmering issues around current Fourth Amendment doctrine, as the Cato Institute’s brief for the Court suggested. The Court indeed eschewed the backward “reasonable expectation of privacy” test, which finds that Fourth Amendment interest exists when people reasonably feel that it does. It instead examined whether the government’s scheme was reasonable, which is where the language of the Fourth Amendment focuses courts’ attention. But the Court did not broadcast the inapplicability of “reasonable expectation” doctrine, so most lawyers and lower courts will probably not realize that another in a growing line of cases is applying the Fourth Amendment in a new and better way, by hewing more closely to the text.

Part of the reason the Court didn’t take all the constitutional bait was the unusually narrow challenge the hoteliers brought. They attacked the collection of information by the government, granting for the sake of argument in this case that the government has the power to require them to collect information about their customers for the government’s later use. Had the Court considered the totality of what we called “the warrantless search scheme,” it would have had to assess whether it is reasonable in our constitutional system for private businesses to be dragooned into wholesale, comprehensive surveillance on behalf of the government. That scope might have brought the Court’s conservatives off the sidelines and into defending the degree of privacy against government that existed when the Fourth Amendment was adopted. (Surely, the government couldn’t have conscripted businesses into mass surveillance of the public at the time of the framing.)

Folks who are paying attention will recognize that the “reasonable expectation of privacy” test continues to recede in importance. We will continue to wait, though, for the case that clearly and articulately applies the right against unreasonable seizures and searches to information as such. While Patel is a technical win, some later case or cases will have to truly address how the Fourth Amendment is to be administered in the modern era.
