Analysis of the Legality of the Secret NSA Warrantless Electronic Surveillance Program

Marty Lederman

We are scholars of constitutional law and former government officials. We write in our individual capacities as citizens concerned by the Bush Administration’s National Security Agency domestic spying program, as reported in the New York Times, and in particular to respond to the Justice Department’s December 22, 2005 letter to the majority and minority leaders of the House and Senate Intelligence Committees setting forth the administration’s defense of the program. Although the program’s secrecy prevents us from being privy to all of its details, the Justice Department’s defense of what it concedes was secret and warrantless electronic surveillance of persons within the United States fails to identify any plausible legal authority for such surveillance. Accordingly the program appears on its face to violate existing law.

The basic legal question here is not new. In 1978, after an extensive investigation of the privacy violations associated with foreign intelligence surveillance programs, Congress and the President enacted the Foreign Intelligence Surveillance Act (FISA). Pub. L. 95-511, 92 Stat. 1783. FISA comprehensively regulates electronic surveillance within the United States, striking a careful balance between protecting civil liberties and preserving the “vitally important government purpose” of obtaining valuable intelligence in order to safeguard national security. S. Rep. No. 95-604, pt. 1, at 9 (1977).

With minor exceptions, FISA authorizes electronic surveillance only upon certain specified showings, and only if approved by a court. The statute specifically allows for warrantless wartime domestic electronic surveillance—but only for the first fifteen days of a war. 50 U.S.C. § 1811. It makes criminal any electronic surveillance not authorized by statute, id. § 1809; and it expressly establishes FISA and specified provisions of the federal criminal code (which govern wiretaps for criminal investigation) as the “exclusive means by which electronic surveillance … may be conducted,” 18 U.S.C. § 2511(2)(f) (emphasis added). [Footnote: More detail about the operation of FISA can be found in Congressional Research Service, “Presidential Authority to Conduct Warrantless Electronic Surveillance to Gather Foreign Intelligence Information” (Jan. 5, 2006). This letter was drafted prior to release of the CRS Report, which corroborates the conclusions drawn here.]

The Department of Justice concedes that the NSA program was not authorized by any of the above provisions. It maintains, however, that the program did not violate existing law because Congress implicitly authorized the NSA program when it enacted the Authorization for Use of Military Force (AUMF) against al Qaeda, Pub. L. No. 107-40, 115 Stat. 224 (2001). But the AUMF cannot reasonably be construed to implicitly authorize warrantless electronic surveillance in the United States during wartime, where Congress has expressly and specifically addressed that precise question in FISA and limited any such warrantless surveillance to the first fifteen days of war.

The DOJ also invokes the President’s inherent constitutional authority as Commander in Chief to collect “signals intelligence” targeted at the enemy, and maintains that construing FISA to prohibit the President’s actions would raise constitutional questions. But even conceding that the President in his role as Commander in Chief may generally collect signals intelligence on the enemy abroad, Congress indisputably has authority to regulate electronic surveillance within the United States, as it has done in FISA. Where Congress has so regulated, the President can act in contravention of statute only if his authority is exclusive, and not subject to the check of statutory regulation. The DOJ letter pointedly does not make that extraordinary claim.

Moreover, to construe the AUMF as the DOJ suggests would itself raise serious constitutional questions under the Fourth Amendment. The Supreme Court has never upheld warrantless wiretapping within the United States. Accordingly, the principle that statutes should be construed to avoid serious constitutional questions provides an additional reason for concluding that the AUMF does not authorize the President’s actions here.
