Legal action

While not directly ruling on the legality of domestic surveillance, the Supreme Court can be seen as having come down on both sides of the Constitution/statute question, in somewhat analogous circumstances.

In Hamdi v. Rumsfeld (2004) the government claimed that AUMF authorized the detention of U.S. citizens designated as an enemy combatant despite its lack of specific language to that effect and notwithstanding the provisions of 18 U.S.C. § 4001(a) that forbids the government to detain an American citizen except by act of Congress. In that case, the Court ruled:

[B]ecause we conclude that the Government's second assertion ["that § 4001(a) is satisfied, because Hamdi is being detained "pursuant to an Act of Congress" [the AUMF]"] is correct, we do not address the first. In other words, for the reasons that follow, we conclude that the AUMF is explicit congressional authorization for the detention of individuals ... and that the AUMF satisfied § 4001(a)'s requirement that a detention be "pursuant to an Act of Congress".

However, in Hamdan v. Rumsfeld the Court rejected the government's argument that AUMF implicitly authorized the President to establish military commissions in violation of the Uniform Code of Military Justice. The Court held:

Neither of these congressional Acts, [AUMF or ATC] however, expands the President's authority to convene military commissions. First, while we assume that the AUMF activated the President's war powers, see Hamdi v. Rumsfeld, 542 U.S. 507 (2004)) (plurality opinion), and that those powers include the authority to convene military commissions in appropriate circumstances, see id., at 518; Quirin, 317 U. S., at 28–29; see also Yamashita, 327 U. S., at 11, there is nothing in the text or legislative history of the AUMF even hinting that Congress intended to expand or alter the authorization set forth in Article 21 of the UCMJ. Cf. Yerger, 8 Wall., at 105 ("Repeals by implication are not favored")

In footnote 23, the Court rejected the notion that Congress is impotent to regulate the exercise of executive war powers:

Whether or not the President has independent power, absent congressional authorization, to convene military commissions, he may not disregard limitations that Congress has, in proper exercise of its own war powers, placed on his powers. See Youngstown Sheet & Tube Co. v. Sawyer, 343 U. S. 579, 637 (1952) (Jackson, J., concurring). The Government does not argue otherwise.

Dozens of civil suits against the government and telecommunications companies over the program were consolidated before the chief judge of the Northern District of California, Vaughn R. Walker. One of the cases was a class-action lawsuit against AT&T, focusing on allegations that the company had provided the NSA with its customers' phone and Internet communications for a data-mining operation. Plaintiffs in a second case were the al-Haramain Foundation and two of its lawyers.^[28][29]

On August 17, 2006, Judge Anna Diggs Taylor of the United States District Court for the Eastern District of Michigan ruled in ACLU v. NSA that the Terrorist Surveillance Program was unconstitutional under the Fourth and First Amendments and enjoined the NSA from using the program to conduct electronic surveillance "in contravention of [FISA or Title III]".^[30] She wrote:^[31]

The President of the United States, a creature of the same Constitution which gave us these Amendments, has indisputably violated the Fourth in failing to procure judicial orders as required by FISA, and accordingly has violated the First Amendment Rights of these Plaintiffs as well.

In August 2007, a three-judge panel of the United States Court of Appeals for the Ninth Circuit heard arguments in two lawsuits challenging the program. On November 16, 2007, the three judges—M. Margaret McKeown, Michael Daly Hawkins and Harry Pregerson—issued a 27-page ruling that the al-Haramain Foundation could not introduce a key piece of evidence because it fell under the government's claim of state secrets, although the judges said that "In light of extensive government disclosures, the government is hard-pressed to sustain its claim that the very subject matter of the litigation is a state secret."^[32][33]

In a question-and-answer session published on August 22, Director of National Intelligence Mike McConnell first confirmed that the private sector had helped the program. McConnell argued that the companies deserved immunity for their help: "Now if you play out the suits at the value they're claimed, it would bankrupt these companies."^[34] Plaintiffs in the AT&T suit subsequently moved to have McConnell's acknowledgement admitted as evidence.^[35]

In a related legal development, on October 13, 2007, Joseph Nacchio, the former CEO of Qwest Communications, appealed an April 2007 insider trading conviction by alleging that the government withdrew opportunities for contracts worth hundreds of millions of dollars after Qwest refused to participate in an unidentified NSA program that the company thought might be illegal. He claimed that the NSA approached Qwest about participating in a warrantless surveillance program more than six months before 9/11. Nacchio used the allegation to show why his stock sale was not improper.^[36] According to a lawsuit filed against other telecommunications companies for violating customer privacy, AT&T began preparing facilities for the NSA to monitor "phone call information and Internet traffic" seven months before 9/11.^[37]

On January 20, 2006, cosponsors Senator Patrick Leahy and Ted Kennedy introduced Senate Resolution 350, a resolution "expressing the sense of the Senate that Senate Joint Resolution 23 (107th Congress), as adopted by the Senate on September 14, 2001, and subsequently enacted as the Authorization for Use of Military Force does not authorize warrantless domestic surveillance of United States citizens".^[38][39] This non-binding resolution died without debate.^[40]

On September 28, 2006, the U.S. House of Representatives passed the Electronic Surveillance Modernization Act (H.R. 5825).^[41] It died in the Senate. Three competing, mutually exclusive, bills—the Terrorist Surveillance Act of 2006 (S.2455), the National Security Surveillance Act of 2006 (S.2455) and the Foreign Intelligence Surveillance Improvement and Enhancement Act of 2006 (S.3001) – were referred for debate to the full Senate,^[42] but did not pass. Each of these bills would have broadened the statutory authorization for electronic surveillance, while subjecting it to some restrictions.

Termination

On January 17, 2007, Gonzales informed Senate leaders that the program would not be reauthorized.^[2] "Any electronic surveillance that was occurring as part of the Terrorist Surveillance Program will now be conducted subject to the approval of the Foreign Intelligence Surveillance Court," according to his letter.^[43]

Further legal action

The American Civil Liberties Union (ACLU) sued NSA over the program. Detroit District Court judge Anna Diggs Taylor ruled on August 17, 2006 that the program was illegal under FISA as well as unconstitutional under the First and Fourth amendments of the Constitution.^[44][30][45] Judicial Watch, a watchdog group, discovered that at the time of the ruling Taylor "serves as a secretary and trustee for a foundation that donated funds to the ACLU of Michigan, a plaintiff in the case".^[46]

ACLU v. NSA was dismissed on January 31, 2007 by the United States Court of Appeals for the Sixth Circuit.^[47] The court did not rule on the spying program's legality. Instead, it declared that the plaintiffs did not have standing to sue because they could not demonstrate that they had been direct targets of the program.^[48] The Supreme Court let the ruling stand.

On August 17, 2007, FISC said it would consider a request by the ACLU that asked the court to make public its recent, classified rulings on the scope of the government's wiretapping powers. FISC presiding judge Colleen Kollar-Kotelly signed an order calling the ACLU's motion "an unprecedented request that warrants further briefing".^[49] The FISC ordered the government to respond on the issue by August 31.^[50][51] On the August 31 deadline, the National Security Division of the Justice Department filed a response in opposition to the ACLU's motion.^[52] On February 19, 2008, the U.S. Supreme Court, without comment, turned down an ACLU appeal, letting stand the earlier decision dismissing the case.^[53]

On September 18, 2008, the Electronic Frontier Foundation (EFF) sued the NSA, President Bush, Vice President Cheney, Cheney's chief of staff David Addington, Gonzales and other government agencies and individuals who ordered or participated in the program. They sued on behalf of AT&T customers. An earlier, ongoing suit (Hepting v. AT&T) by the EFF bogged down over the recent FISA changes.^[54][55]

On January 23, 2009, the Obama administration adopted the same position as its predecessor when it urged Judge Walker to set aside a ruling in Al-Haramain Islamic Foundation et al. v. Obama, et al.^[56] The Obama administration sided with the Bush administration in its legal defense of July 2008 legislation that immunized the nation's telecommunications companies from lawsuits accusing them of complicity in the program, according to Attorney General Eric Holder.^[57]

On March 31, 2010, Judge Walker ruled that the program was illegal when it intercepted phone calls of Al Haramain. Declaring that the plaintiffs had been "subjected to unlawful surveillance", the judge said the government was liable for damages.^[58] In 2012, the Ninth Circuit vacated the judgment against the United States and affirmed the district court's dismissal of the claim.^[59]

Proposed FISA amendments

Several commentators raised the issue of whether FISA needed to be amended to address foreign intelligence needs, technology developments and advanced technical intelligence gathering. The intent was to provide programmatic approvals of surveillance of foreign terrorist communications, so that they could then legally be used as evidence for FISA warrants. Fixing Surveillance;^[60] Why We Listen,^[61] The Eavesdropping Debate We Should be Having;^[62] A New Surveillance Act;^[63] A historical solution to the Bush spying issue,^[64] Whispering Wires and Warrantless Wiretaps^[65] address FISA's inadequacies in the post-9/11 context.

The Bush administration contended that amendment was unnecessary because they claimed that the President had inherent authority to approve the NSA program, and that the process of amending FISA might require disclosure of classified information that could harm national security.^[19] In response, Senator Leahy said, "If you do not even attempt to persuade Congress to amend the law, you must abide by the law as written."^[66] President Bush claimed that the law did not apply because the Constitution gave him "inherent authority" to act.^[67][68]

Some politicians and commentators used "difficult, if not impossible" to argue that the administration believed Congress would have rejected an amendment. In his written "Responses to Questions from Senator Specter" in which Specter specifically asked why the administration had not sought to amend FISA,^[69] Gonzales wrote:

[W]e were advised by members of Congress that it would be difficult, if not impossible to pass such legislation without revealing the nature of the program and the nature of certain intelligence capabilities. That disclosure would likely have harmed our national security, and that was an unacceptable risk we were not prepared to take.

Competing legislative proposals to authorize the NSA program subject to Congressional or FISC oversight were the subject of Congressional hearings.^[70] On March 16, 2006, Senators Mike DeWine, Lindsey Graham, Chuck Hagel and Olympia Snowe introduced the Terrorist Surveillance Act of 2006 (S.2455),^[71][72] that gave the President limited statutory authority to conduct electronic surveillance of suspected terrorists in the US, subject to enhanced Congressional oversight. That day Specter introduced the National Security Surveillance Act of 2006 (S.2453),^[73][74] which would amend FISA to grant retroactive amnesty^[75] for warrantless surveillance conducted under presidential authority and provide FISC jurisdiction to review, authorize and oversee "electronic surveillance programs". On May 24, 2006, Specter and Feinstein introduced the Foreign Intelligence Surveillance Improvement and Enhancement Act of 2006 (S.3001) denoting FISA as the exclusive means to conduct foreign intelligence surveillance.

On September 13, 2006, the Senate Judiciary Committee voted to approve all three, mutually exclusive bills, thus, leaving it to the full Senate to resolve.^[42]

On July 18, 2006, U.S. Representative Heather Wilson introduced the Electronic Surveillance Modernization Act (H.R. 5825). Wilson's bill would give the President the authority to authorize electronic surveillance of international phone calls and e-mail linked specifically to identified terrorist groups immediately following or in anticipation of an armed or terrorist attack. Surveillance beyond the initially authorized period would require a FISA warrant or a presidential certification to Congress. On September 28, 2006 the House of Representatives passed Wilson's bill and it was referred to the Senate.^[41]

Each of these bills would in some form broaden the statutory authorization for electronic surveillance, while still subjecting it to some restrictions. The Specter-Feinstein bill would extend the peacetime period for obtaining retroactive warrants to seven days and implement other changes to facilitate eavesdropping while maintaining FISC oversight. The DeWine bill, the Specter bill, and the Electronic Surveillance Modernization Act (already passed by the House) would all authorize some limited forms or periods of warrantless electronic surveillance subject to additional programmatic oversight by either the FISC (Specter bill) or Congress (DeWine and Wilson bills).

FISC order

On January 18, 2007, Gonzales told the Senate Judiciary Committee,

Court orders issued last week by a Judge of the Foreign Intelligence Surveillance Court will enable the government to conduct electronic surveillance – very specifically, surveillance into or out of the United States where there is probable cause to believe that one of the communicants is a member or agent of al Qaeda or an associated terrorist organization – subject to the approval of the FISC. We believe that the court's orders will allow the necessary speed and agility the government needs to protect our Nation from the terrorist threat.^[76]

The ruling by the FISC was the result of a two-year effort between the White House and the court to find a way to obtain court approval that also would "allow the necessary speed and agility" to find terrorists, Gonzales said in a letter to the top committee members. The court order on January 10 will do that, Gonzales wrote. Senior Justice department officials would not say whether the orders provided individual warrants for each wiretap or whether the court had given blanket legal approval for the entire NSA program. The ACLU said in a statement that "without more information about what the secret FISC has authorized, there is no way to determine whether the NSA's current activities are lawful".^[77] Law professor Chip Pitts argued that substantial legal questions remain regarding the core NSA program as well as the related data mining program (and the use of National Security Letters), despite the government's apparently bringing the NSA program within the purview of FISA.^[78]

FISCR ruling

In August 2008, the United States Foreign Intelligence Surveillance Court of Review (FISCR) affirmed the constitutionality of the Protect America Act of 2007 in a heavily redacted opinion released on January 15, 2009, only the second such public ruling since the enactment of the FISA Act.^{[79][80][81][82][83]}

U.S. Constitution

National Security Act of 1947

The National Security Act of 1947^[101] requires Presidential findings for covert acts. SEC. 503. [50 U.S.C. 413b] (a) (5) of that act states: "A finding may not authorize any action that would violate the Constitution or any statute of the United States."

Under § 501–503, codified as 50 USC § 413-§ 413b,^[102] the President is required to keep Congressional intelligence committees "fully and currently" informed of U.S. intelligence activities, "consistent with ... protection from unauthorized disclosure of classified information relating to sensitive intelligence sources and methods or other exceptionally sensitive matters." For covert actions, from which intelligence gathering activities are specifically excluded in § 413b(e)(1), the President is specifically permitted to limit reporting to selected Members.^[103]

Foreign Intelligence Surveillance Act

The 1978 Foreign Intelligence Surveillance Act (FISA) regulates government agencies' physical searches and electronic surveillance, in cases wherein a significant purpose is to gather foreign intelligence information. "Foreign intelligence information" is defined in 50 U.S.C. § 1801 as information necessary to protect the U.S. or its allies against actual or potential attack from a foreign power, sabotage or international terrorism. FISA defines a "foreign power" as a foreign government or any faction(s) of a foreign government not substantially composed of US persons, or any entity directed or controlled by a foreign government. FISA provides for both criminal and civil liability for intentional electronic surveillance under color of law except as authorized by statute.

FISA specifies two documents for the authorization of surveillance. First, FISA allows the Justice Department to obtain warrants from the Foreign Intelligence Surveillance Court (FISC) before or up to 72 hours after the beginning of the surveillance. FISA authorizes a FISC judge to issue a warrant if "there is probable cause to believe that ... the target of the electronic surveillance is a foreign power or an agent of a foreign power." 50 U.S.C. § 1805(a)(3). Second, FISA permits the President or his delegate to authorize warrantless surveillance for the collection of foreign intelligence if "there is no substantial likelihood that the surveillance will acquire the contents of any communication to which a United States person is a party". 50 U.S.C. § 1802(a)(1).^[104]

In 2002, the United States Foreign Intelligence Surveillance Court of Review (Court of Review) met for the first time and issued an opinion (In re: Sealed Case No. 02-001). They noted that all of the Federal courts of appeal had considered the issue and concluded that constitutional power allowed the president to conduct warrantless foreign intelligence surveillance. Furthermore, based on these rulings it "took for granted such power exists" and ruled that under this presumption, "FISA could not encroach on the president's constitutional power."

18 U.S.C. § 2511(2)(f) provides in part that FISA "shall be the exclusive means by which electronic surveillance, as defined in 50 U.S.C. § 1801(f) ... and the intercept of domestic [communications] may be conducted". The statute includes a criminal sanctions subpart 50 U.S.C. § 1809 granting an exception, "unless authorized by statute".

Authorization for the Use of Military Force

The Authorization for Use of Military Force was passed by Congress shortly after the 9/11 attacks. AUMF was used to justify the Patriot Act and related laws. It explicitly states in Section 2:

(a) IN GENERAL- That the President is authorized to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons.

USA PATRIOT Act

Section 215 of the PATRIOT act authorized the FBI to subpoena some or all business records from a business record holder using a warrant applied for in the Foreign Intelligence Surveillance Court.

Terrorist surveillance program

The legality of surveillance involving US persons and extent of this authorization is the core of this controversy which includes:

• Constitutional issues concerning the separation of powers and the Fourth Amendment immunities
• The program's effectiveness^[105] and scope^[106]
• The legality of the leaking and publication of classified information and their implications for national security
• Adequacy of FISA as a tool for fighting terrorism

Constitutional issues

The constitutional debate surrounding the program is principally about separation of powers. If no "fair reading" of FISA can satisfy the canon of avoidance, these issues must be decided at the appellate level. In such a separation of powers dispute, Congress bears burden of proof to establish its supremacy: the Executive branch enjoys the presumption of authority until an Appellate Court rules against it.^[121]

FISA practicality

FISA grants FISC the exclusive power to authorize surveillance of US persons as part of foreign intelligence gathering and makes no separate provision for surveillance in wartime. The interpretation of FISA's exclusivity clause is central because both sides agree that the NSA program operated outside FISA. If FISA is the controlling authority, the program is illegal.^[127]

The "no constitutional issue" critique is that Congress has the authority to legislate in this area under Article I and the Fourth Amendment,^[128] while the "constitutional conflict" critique^[129] claims that the delineation between Congressional and Executive authority in this area is unclear,^[130] but that FISA's exclusivity clause shows that Congress had established a role for itself in this arena.

The Bush administration argued both that the President had the necessary power based solely on the Constitution and that conforming to FISA was not practical given the circumstances. Assistant Attorney General for Legislative Affairs, William Moschella, wrote:

As explained above, the President determined that it was necessary following September 11 to create an early warning detection system. FISA could not have provided the speed and agility required for the early warning detection system. In addition, any legislative change, other than the AUMF, that the President might have sought specifically to create such an early warning system would have been public and would have tipped off our enemies concerning our intelligence limitations and capabilities.

FBI Special Agent Coleen Rowley, in her capacity as legal counsel to the Minneapolis Field Office^[131] recounted how FISA procedural hurdles had hampered the FBI's investigation of Zacarias Moussaoui (the so-called "20th hijacker") prior to the 9/11 attacks. Among the factors she cited were the complexity of the application, the amount of detailed information required, confusion by field operatives about the standard of probable cause required by the FISC and the strength of the required link to a foreign power. At his appearance before the Senate Judiciary Committee in June 2002, FBI Director Robert Mueller responded to questions about the Rowley allegations, testifying that unlike normal criminal procedures, FISA warrant applications are "complex and detailed", requiring the intervention of FBI Headquarters (FBIHQ) personnel trained in a specialized procedure (the "Woods" procedure) to ensure accuracy.^[132]

The Supreme Court made no ruling on this question. However, on June 29, 2006, in Hamdan, the Supreme Court rejected an analogous argument. Writing for the majority, Justice John Paul Stevens, while ruling that "the AUMF activated the President's war powers, and that those powers include the authority to convene military commissions in appropriate circumstances" (citations omitted), held that nothing in the AUMF language expanded or altered the Uniform Code of Military Justice (which governs military commissions.) Stevens distinguished Hamdan from Hamdi (in which AUMF language was found to override the explicit language regarding detention in 18 U.S.C. § 4001(a)) in that Hamdan would require a "Repeal by implication" of the UCMJ.

Authorizing statute

The Bush administration held that AUMF enables warrantless surveillance because it is an authorizing statute.

An Obama Department of Justice whitepaper interpreted FISA's "except as authorized by statute" clause to mean that Congress allowed for future legislative statute(s) to provide exceptions to the FISA warrant requirements^[133] and that the AUMF was such a statute. They further claimed that AUMF implicitly provided executive authority to authorize warrantless surveillance.

This argument is based on AUMF language, specifically, the acknowledgment of the President's Constitutional authority contained in the preamble:

Whereas, the President has authority under the Constitution to take action to deter and prevent acts of international terrorism against the United States ...

and the language in the resolution;

[Be it resolved] [t]hat the President is authorized to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons.

The Obama administration further claimed that Title II of the USA PATRIOT Act entitled Enhanced Surveillance Procedures also allowed the program,^[134] Obama stated that Americans' civil liberties were protected and that purely domestic wiretapping was conducted only pursuant to warrants.^[135]

Because FISA authorizes the President to bypass the FISC only during the first 15 days of a war declared by Congress, the argument claimed the AUMF implicitly gave the President the necessary power (as would any Congressional declaration of war). However, as a declaration of war encompasses all military actions so declared, including any otherwise constrained by Congress, the administration held that FISA set a presumptive minimum, which might be extended (explicitly or implicitly) by a declaration.

Corporate confidentiality analysis

Corporate secrecy is also an issue. In a letter to the EFF, AT&T objected to the filing of the documents in any manner, saying that they contain sensitive trade secrets and could be "used to 'hack' into the AT&T network, compromising its integrity".^[136] However, Chief Judge Walker stated, during the September 12, 2008 hearing in the EFF class-action lawsuit, that the Klein evidence could be presented in court, effectively ruling that AT&T's trade secret and security claims were unfounded.

Duty to notify Congress

The Bush administration contended that with regard to the NSA program, it had fulfilled its notification obligations by briefing key members of Congress (thirteen individuals between the 107th and 109th Congressional sessions) more than a dozen times,^[137] but they were forbidden from sharing that information with other members or staff.

The CRS report asserted that the specific statutory notification procedure for covert action did not apply to the NSA program. It is not clear whether a restricted notification procedure intended to protect sources and methods was expressly prohibited. Additionally, the sources and methods exception requires a factual determination as to whether it should apply to disclosure of the program itself or only to specific aspects.

Peter J. Wallison, former White House Counsel to President Ronald Reagan stated, "It is true, of course, that a president's failure to report to Congress when he is required to do so by law is a serious matter, but in reality the reporting requirement was a technicality that a President could not be expected to know about."^[138]

War Powers Resolution

The majority of legal arguments supporting the program were based on the War Powers Resolution. The War Powers Resolution has been questioned since its creation, and its application to the NSA program was questioned.

Other arguments

Philip Heymann claimed Bush had misstated the In re: Sealed Case No. 02-001 ruling that supported Congressional regulation of surveillance. Heymann said, "The bottom line is, I know of no electronic surveillance for intelligence purposes since the Foreign Intelligence Surveillance Act was passed that was not done under the ... statute."^[139]

Cole, Epstein, Heynmann, Beth Nolan, Curtis Bradley, Geoffrey Stone, Harold Koh, Kathleen Sullivan, Laurence Tribe, Martin Lederman, Ronald Dworkin, Walter Dellinger, William Sessions and William Van Alstyne wrote, "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."^[140] They summarized:

If the administration felt that FISA was insufficient, the proper course was to seek legislative amendment, as it did with other aspects of FISA in the Patriot Act, and as Congress expressly contemplated when it enacted the wartime wiretap provision in FISA. One of the crucial features of a constitutional democracy is that it is always open to the President—or anyone else—to seek to change the law. But it is also beyond dispute that, in such a democracy, the President cannot simply violate criminal laws behind closed doors because he deems them obsolete or impracticable.

Law school dean Robert Reinstein asserted that the warrantless domestic spying program is^[141][142]

a pretty straightforward case where the president is acting illegally. ... When Congress speaks on questions that are domestic in nature, I really can't think of a situation where the president has successfully asserted a constitutional power to supersede that. ... This is domestic surveillance over American citizens for whom there is no evidence or proof that they are involved in any illegal activity, and it is in contravention of a statute of Congress specifically designed to prevent this.

Law professor Robert M. Bloom and William J. Dunn, a former Defense Department intelligence analyst, claimed:^[143]

President Bush argues that the surveillance program passes constitutional inquiry based upon his constitutionally delegated war and foreign policy powers, as well as from the congressional joint resolution passed following the September 11, 2001 terrorist attacks. These arguments fail to supersede the explicit and exhaustive statutory framework provided by Congress and amended repeatedly since 2001 for judicial approval and authorization of electronic surveillance. The specific regulation by Congress based upon war powers shared concurrently with the President provides a constitutional requirement that cannot be bypassed or ignored by the President.

Law professor Jordan Paust argued:^[144]

any so-called inherent presidential authority to spy on Americans at home (perhaps of the kind denounced in Youngstown (1952) and which no strict constructionist should pretend to recognize), has been clearly limited in the FISA in 18 U.S.C. § 2511(2)(f) and 50 U.S.C. § 1809(a)(1), as supplemented by the criminal provisions in 18 U.S.C. § 2511(1).

Law Dean Harold Koh, Suzanne Spaulding and John Dean contended that FISA was controlling,^[145] (in seeming disagreement with the FISC of Review finding) and that the President's admissions constituted sufficient evidence of a violation of the Fourth Amendment, without requiring further factual evidence.

Law professor John C. Eastman compared the CRS and DOJ reports and concluded instead that under the Constitution and ratified by both historical and Supreme Court precedent, "the President clearly has the authority to conduct surveillance of enemy communications in time of war and of the communications to and from those he reasonably believes are affiliated with our enemies. Moreover, it should go without saying that such activities are a fundamental incident of war."^[146]

Law professor Orin Kerr argued that the part of In re: Sealed Case No. 02-001 that dealt with FISA (rather than the Fourth Amendment) was nonbinding obiter dicta and that the argument did not restrict Congress's power to regulate the executive in general.^[147] Separately Kerr argued for wireless surveillance based on the fact that the border search exception permits searches at the border "or its functional equivalent." (United States v. Montoya De Hernandez, 473 U.S. 531, 538 (1985)). As a sovereign nation the US can inspect goods crossing the border. The ruling interpreted the Fourth Amendment to permit such searches. Courts have applied the border search exception to computers and hard drives, e.g., United States v. Ickes, 393 F.3d 501 (4th Cir. 2005) Case law does not treat data differently than physical objects. Case law applies the exception to international airports and international mail (United States v. Ramsey). Case law is phrased broadly. The exception could analogously apply to monitoring an ISP or telephony provider.^[148][149]

U.S. District Judge Dee Benson, who served on the FISC, stated that he was unclear on why the FISC's emergency authority would not meet the administration's stated "need to move quickly".^[150][151] The court was also concerned about "whether the administration had misled their court about its sources of information on possible terrorism suspects ... [as this] could taint the integrity of the court's work."^[152]

Judge Richard Posner opined that FISA "retains value as a framework for monitoring the communications of known terrorists, but it is hopeless as a framework for detecting terrorists. [FISA] requires that surveillance be conducted pursuant to warrants based on probable cause to believe that the target of surveillance is a terrorist, when the desperate need is to find out who is a terrorist."^[153]

Earlier warrantless surveillance

The Bush administration compared the NSA warrantless surveillance program with historical wartime warrantless searches in the US, going back to the time of the nation's founding.^[5]

Critics pointed out that the first warrantless surveillance occurred before the adoption of the U.S. Constitution, and the other historical precedents cited by the administration were before FISA's passage and therefore did not directly contravene federal law.^[129] Earlier electronic surveillance by the federal government such as Project SHAMROCK, led to reform legislation in the 1970s.^[154] Advancing technology presented novel questions as early as 1985.^[155]

Executive orders by previous administrations including Presidents Clinton and Carter authorized their Attorneys General to exercise authority with respect to both options under FISA.^[156][157] Clinton's executive order authorized his Attorney General "[pursuant] to section 302(a)(1)" to conduct physical searches without court order "if the Attorney General makes the certifications required by that section".

Unitary Executive theory

The Unitary Executive theory as interpreted by John Yoo et al., supported the Bush administration's Constitutional argument. He argued that the President had the "inherent authority to conduct warrantless searches to obtain foreign intelligence".^[158][159]

The United States Court of Appeals for the District of Columbia ruled that the President's authority as commander-in-chief extends to the "independent authority to repel aggressive acts ... without specific congressional authorization" and without court review of the "level of force selected".^[160] Whether such declarations applying to foreign intelligence are or must be in compliance with FISA has been examined by few courts.

Classified information

Administration response to press coverage

On December 17, 2005, President Bush addressed the growing controversy in his weekly radio broadcast.^[167] He stated that he was using his authority as President, as Commander in Chief and such authority as the Congress had given him, to intercept international communications of "people with known links to al Qaeda and related terrorist organizations". He added that before intercepting any communications, "the government must have information that establishes a clear link to these terrorist networks." He speculated that had the right communications been intercepted, perhaps the 9/11 attacks could have been prevented. He said the NSA program was re-authorized every 45 days, having at that time been reauthorized "more than 30 times"; it was reviewed by DOJ and NSA lawyers "including NSA's general counsel and inspector general", and Congress leaders had been briefed "more than a dozen times".^[168]

In a speech in Buffalo, New York on April 20, 2004, he said that:

Secondly, there are such things as roving wiretaps. Now, by the way, any time you hear the United States government talking about wiretap, it requires – a wiretap requires a court order. Nothing has changed, by the way. When we're talking about chasing down terrorists, we're talking about getting a court order before we do so. It's important for our fellow citizens to understand, when you think Patriot Act, constitutional guarantees are in place when it comes to doing what is necessary to protect our homeland, because we value the Constitution.^[169]

And again, during a speech at Kansas State University on January 23, 2006, President Bush mentioned the program, and added that it was "what I would call a terrorist surveillance program", intended to "best ... use information to protect the American people",^[170] and that:

What I'm talking about is the intercept of certain communications emanating between somebody inside the United States and outside the United States; and one of the numbers would be reasonably suspected to be an al Qaeda link or affiliate. In other words, we have ways to determine whether or not someone can be an al Qaeda affiliate or al Qaeda. And if they're making a phone call in the United States, it seems like to me we want to know why. This is a – I repeat to you, even though you hear words, "domestic spying," these are not phone calls within the United States. It's a phone call of an al Qaeda, known al Qaeda suspect, making a phone call into the United States ... I told you it's a different kind of war with a different kind of enemy. If they're making phone calls into the United States, we need to know why – to protect you.

During a speech^[171] in New York on January 19, 2006 Vice President Cheney commented on the controversy, stating that a "vital requirement in the war on terror is that we use whatever means are appropriate to try to find out the intentions of the enemy," that complacency towards further attack was dangerous, and that the lack of another major attack since 2001 was due to "round the clock efforts" and "decisive policies", and "more than luck." He stated:

[B]ecause you frequently hear this called a 'domestic surveillance program.' It is not. We are talking about international communications, one end of which we have reason to believe is related to al Qaeda or to terrorist networks affiliated with al Qaeda.. a wartime measure, limited in scope to surveillance associated with terrorists, and conducted in a way that safeguards the civil liberties of our people.

General Michael Hayden

In a press conference on December 19 held by both Attorney General Gonzales and General Michael Hayden, the Principal Deputy Director for National Intelligence, General Hayden claimed, "This program has been successful in detecting and preventing attacks inside the United States." He stated that even an emergency authorization under FISA required marshaling arguments and "looping paperwork around". Hayden implied that decisions on whom to intercept under the wiretapping program were being made on the spot by a shift supervisor and another person, but refused to discuss details of the specific requirements for speed.^[19]

Beginning in mid-January 2006 public discussion increased on the legality of the terrorist surveillance program.^[172]

DOJ sent a 42-page white paper to Congress on January 19, 2006 stating the grounds upon which it was felt the NSA program was legal, which restated and elaborated on reasoning Gonzales used at the December press conference.^[173] Gonzales spoke again on January 24, claiming that Congress had given the President the authority to order surveillance without going through the courts, and that normal procedures to order surveillance were too slow and cumbersome.^[174]

General Hayden stressed the NSA's respect for the Fourth Amendment, stating at the National Press Club on January 23, 2006, "Had this program been in effect prior to 9/11, it is my professional judgment that we would have detected some of the 9/11 al Qaeda operatives in the United States, and we would have identified them as such."^[175]

In a speech on January 25, 2006, President Bush said, "I have the authority, both from the Constitution and the Congress, to undertake this vital program,"^[176] telling the House Republican Caucus at their February 10 conference in Maryland that "I wake up every morning thinking about a future attack, and therefore, a lot of my thinking, and a lot of the decisions I make are based upon the attack that hurt us."^[177]

President Bush reacted to a May 10 domestic call records article by restating his position, that it is "not mining or trolling through the personal lives of millions of innocent Americans".^[178]

Congressional response

Three days after news broke about the NSA program, a bipartisan group of Senators—Democrats Dianne Feinstein, Carl Levin, Ron Wyden and Republicans Chuck Hagel and Olympia Snowe, wrote to the Judiciary and Intelligence Committee chairs and ranking members requesting the two committees to "seek to answer the factual and legal questions" about the program.

On January 20, 2006, in response to the administration's asserted claim to base the NSA program in part on the AUMF, Senators Leahy and Kennedy introduced Senate Resolution 350 that purported to express a "sense of the Senate" that the AUMF "does not authorize warrantless domestic surveillance of United States citizens".^[38][39] It was not reported out of committee.^[40]

In introducing their resolution to committee,^[179] they quoted Supreme Court Justice Sandra Day O'Connor's opinion that even war "is not a blank check for the President when it comes to the rights of the Nation's citizens".

Additionally, they asserted that the DOJ legal justification was a "manipulation of the law" similar to other "overreaching" and "twisted interpretations" in recent times. Leahy and Kennedy also asserted that Gonzales had "admitted" at a press conference on December 19, 2005, that the Administration did not seek to amend FISA to authorize the NSA spying program because it was advised that "it was not something we could likely get." (However, as noted below under "Proposed Amendments to FISA", Gonzales made clear that what he actually said was that such an amendment was "not something [they] could likely get" without disclosing the nature of the program and operational limitations and that it was believed that such disclosure would be damaging to national security.)

Leahy and Kennedy asserted that the procedures adopted for the NSA program, specifically the 45-day reapproval cycle was "not good enough" because the review group were executive branch appointees. Finally, they concluded that Congressional and Judicial oversight were fundamental and should not be unilaterally discarded.

In February 2008, the Bush administration backed a new version of FISA that would grant telecom companies retroactive immunity from lawsuits stemming from surveillance. On March 14, the House passed a bill that did not grant such immunity.

Anonymity networks

Edward Snowden copied and leaked thousands of classified NSA documents to journalists. The information revealed the access of some federal agencies to the public's online identity and led to wider use anonymizing technologies. In late 2013, soon after Snowden's leaks, it was loosely calculated that encrypted browsing software, such as Tor, I2P and Freenet had "combined to more than double in size ... and approximately 1,050,000 total machines 'legitimately' use the networks on a daily basis, amounting to an anonymous population that is about 0.011 percent of all machines currently connected to the Internet."^[180] Given that these tools are designed to protect the identity and privacy of their users, an exact calculation of the growth of the anonymous population cannot be accurately rendered, but all estimates predict rapid growth.

These networks were accused of supporting illegal activity. They can be used for the illicit trade of drugs, guns and pornography. However, Tor executive director Roger Dingledine claimed that the "hidden services" represent only 2 percent of total traffic on Tor's network.^[181] This fact suggests that the large majority of those who use it do so in order to protect their normal browsing activity, an effort to protect their personal values of privacy rather than to participate in illegal activity.

Trade-off between security and liberty

Polls analyzed the trade-off between security and liberty. A June 2015 poll conducted by Gallup asked participants if the US should take all the necessary steps to prevent terrorist attacks even if civil liberties are violated. 30% of respondents agreed: 65% instead said take steps, but do not violate civil liberties.^[182]

In a 2004 Pew poll, 60% of respondents rejected the idea of sacrificing privacy and freedom in the name of security.^[183] By 2014 a similar Pew poll found that 74% of respondents preferred privacy, while 22% said the opposite. Pew noted that post 9/11 surveys revealed that in the periods during which prominent incidents that related to privacy and security first came up, the majority of respondents favored an ideology of "security first", while maintaining that a dramatic reduction in civil liberties should be avoided. Events often caused Americans to back allow government to investigate suspected terrorists more effectively, even if those steps might infringe on the privacy of ordinary citizens. The majority of respondents reject steps that translate into extreme intrusion into their lives.^[184]

Various administrations claimed that reducing privacy protections reduces obstacles that anti-terrorism agencies face attempting to foil terrorist attacks and that fewer privacy protections makes it more difficult for terrorist groups to operate.^[185]
