Surveillance and International Terrorism Intelligence Exchange: Balancing the Interests of National Security and Individual Liberty

Abstract

ABSTRACTUsing the revelations Edward Snowden passed over to the press regarding the actions of the U.S.’s National Security Agency and the UK’s Government Communications Headquarters and their use of the Prism project, this article examines the law surrounding intelligence gathering in the U.S. and UK. Underpinning the analysis is the legal principle of proportionality as applied to balancing the interests of national security and individual liberties. After examining intelligence exchange procedures, which for the UK is through negotiated agreements between national security agencies and through the European Union’s policing agency, Europol, the main part of the article discusses legal challenges that have been made regarding surveillance and the use of anti-terror laws on citizens and the rationale behind the judicial decisions made in both the U.S. and UK jurisdictions. The argument forwarded is that there is a requirement for wide preventative powers being granted to counter-terrorism agencies and that the interests of national security and individual liberty are inclusive and, as shown by the cases covered in this article, we should rely on the judiciary to perform their function in applying proportionality to each case on its own merits.
