Balancing National Security and Privacy in Surveillance Laws: A Critical Examination of Contemporary Legal Frameworks

One of the most important legal and political issues of the 21st century is the conflict between national security and privacy. Democratic governments are expanding their surveillance capabilities to combat terrorism, cyberattacks, and foreign espionage. But they run the risk of going against the constitutional freedoms that give democracy its meaning. The United States Foreign Intelligence Surveillance Act (FISA) Section 702, which was reauthorized in 2024 by the Reforming Intelligence and Securing America Act (RISAA) and is set to expire in April 2026, is the focus of this study, which looks at how contemporary surveillance law navigates and frequently struggles with this fundamental conflict. This paper argues, based on statutory analysis, judicial oversight mechanisms, comparative legal perspectives, and recent legislative history, that neither absolute privacy nor security can be achieved. What is achievable is a principled framework built on proportionality, judicial accountability, and transparent governance—one that refuses to treat security and liberty as mutually exclusive. In the paper's conclusion, a set of reform recommendations are made that have the potential to balance the effectiveness of intelligence with the protection of civil rights in a world that is being watched more and more.
