The US legal system on data protection in the field of law enforcement. Safeguards, rights and remedies for EU citizens

EXECUTIVE SUMMARY OF STUDY FOR THE EUROPEAN PARLIAMENT LIBE COMMITTEE PUBLISHED HERE

by Francesca BIGNAMI (*)

In US law, there are a number of different legal sources that govern data protection in the field of federal law enforcement. This study first considers the two most important sources of data protection law^the Fourth Amendment to the US Constitution and the Privacy Act of 1974. It then turns to the most significant methods of information collection that are available for ordinary criminal investigations and national security investigations and the data protection guarantees set down under the laws authorizing and regulating such information collection.

The Fourth Amendment prohibits “unreasonable searches and seizures” by the government. Reasonableness is established if the search or seizure is conducted pursuant to a valid warrant, that is, a judicial order based on a showing of probable cause and on a particular description of the property to be searched and the items to be seized. Reasonableness can also be established if one of the exceptions to the warrant requirements exists. In the data protection context, however, the application of the Fourth Amendment is relatively limited because of the third-party records doctrine which holds that individuals do not have an expectation of privacy in personal data that they voluntarily turn over to third parties like financial institutions and communications providers. With regard to EU citizens, the Supreme Court has held that foreign citizens resident abroad are not covered by the Fourth Amendment.

Among U.S. laws, the Privacy Act of 1974 is the closest analogue to a European data protection law in that it seeks to regulate comprehensively personal data processing, albeit only with respect to federal government departments and agencies. It regulates the collection, use, and disclosure of all types of personal information, by all types of federal agencies, including law enforcement agencies. At a general level, the Privacy Act contains most of the elements of the EU right to personal data protection. However, it only protects US citizens and permanent residents, not EU citizens.

Furthermore, there are a number of exemptions available specifically for law enforcement agencies. As a result, the benefits of the proposed legislation on judicial redress for EU citizens are unclear. The proposed legislation contemplates three types of law suits, two of which are designed to protect the right of access to and correction of personal data, and one of which enables individuals to obtain compensation for unlawful disclosures of personal data. Since law enforcement agencies commonly exempt their data bases from the access requirements of the Privacy Act, the right of action for intentional or willful disclosures that cause actual damage is the only one that would be available on a general basis.

In investigations involving ordinary crime, there are at least three different methods of personal data collection available to law enforcement officials: (1) use of private sources like commercial data brokers; (2) court and administrative subpoenas; (3) electronic surveillance and access to electronic communications based on a court order under the Electronic Communications Privacy Act. These information-gathering methods afford the same level of data protection for US and EU citizens.

With respect to EU data protection law, however, some of these methods contain relatively few data protection guarantees.

In the case of private sources of personal data, this is attributable to the absence of a comprehensive data protection scheme in the private sector and the vast quantities of personal information freely available to market actors and, consequently, also to law enforcement officials. With respect to the subpoena power and access to communications metadata and subscriber records (under the Stored Communications Act and the Pen Register Act), the lack of significant data protection guarantees is associated with the standard of “relevance” to any type of criminal investigation and the permissive application of that standard by the courts. The law and jurisprudence of “relevance,” in turn, is driven by the failure of US law to recognize a robust privacy interest in the personal data held by corporate entities and other third parties.

In investigations involving national security threats, which can involve both an intelligence and a law enforcement component, there are a number of additional means available to the government: (1) a special type of administrative subpoena known as a “national security letter”; (2) surveillance authorized by the Foreign Intelligence Surveillance Act (FISA); (3) any other form of intelligence gathering authorized by Executive Order 12,333 (and not covered by FISA). The information gathered through such methods can be shared with criminal prosecutors if relevant for law enforcement purposes.

Foreign intelligence gathering, both inside and outside the United States, follows a two-track scheme, one for US persons and another for non-US persons. With the exception of FISA electronic and physical surveillance orders, the data protection guarantees afforded to non-US persons are minimal. The stated intent of Presidential Policy Directive 28 is to provide for stronger personal data protection for non-US persons, but it is difficult to come to any conclusions at this point in time on what effect it will have.

More generally, even with respect to US persons, personal data protection under foreign intelligence law raises a couple of questions.

The first concerns the point in time when the right to privacy is burdened by government action. The US government has suggested that in the case of bulk collection of personal data, harm to the privacy interest only occurs after the personal data is used to search, or results from a search of, the information included in the data base.

This position stands in marked contrast with EU law, where it is well established that bulk collection, even before the personal data is accessed, is a serious interference with the right to personal data protection because of the number of people and the amount of personal data involved.

The second question concerns the conditions under which personal data can be shared between intelligence and law enforcement officials. In the realm of data processing by law enforcement and intelligence agencies, the European courts have emphasized that intrusive surveillance can only be conducted to combat serious threats that are carefully defined in law. They have also held that the information that results from such surveillance can only be used to combat those serious threats, whether to take national security measures or to prosecute the associated criminal offenses. In US law, by contrast, the law allows for intelligence to be transferred to the police and criminal prosecutors for any type of law enforcement purpose.

One thought on “The US legal system on data protection in the field of law enforcement. Safeguards, rights and remedies for EU citizens

  1. Useful, fascinating topic in an of international data flows. Some additional thoughts to contribute.

    1. Would be useful to have a side by side comparison of data protection rights and remedies in the US and EU for non-citizens of those jurisdictions. Rights of non-EU citizens in the EU and rights of non-US citizens (not just EU citizens) in the US.

    2. Wonder if your study considered mentioned existing policies and procedures that allow EU and all other citizens to seek redress including:
    *2007 DHS privacy policy that provides administrative rights to non-US citizens and permanent residents under the Privacy Act. https://www.dhs.gov/xlibrary/assets/privacy/privacy_policyguide_2007-1.pdf
    *DHS Traveler Redress Program

    3. The Report mentions rights of access. Would be useful to include the Freedom of Information Act (FOIA) that allows (U.S. Citizens and non-US Citizens) rights of access to information about themselves enforceable in a court of law. This has been used successfully by EU citizens including members of EU Parliament to gain access to information about themselves

    4. Oversight over the privacy act involves not just courts but other entities including the office of inspector general and congress. https://www.dhs.gov/xlibrary/assets/privacy/privacy_networked_layered.pdf
