ABSTRACT: Background: Since the September 11, 2001 attacks, liberal democracies have expanded counter-terrorism powers to address evolving security threats. These developments have generated persistent concerns regarding their impact on civil liberties and the effectiveness of existing mechanisms for constraining executive authority. Objective: This study examined how counter-terrorism frameworks in the United States, Canada, the United Kingdom, and France balance national security and civil liberties, and identified the legal and institutional arrangements most effective in limiting governmental overreach. Methods: An interpretivist research philosophy guided a qualitative comparative design based on systematic documentary analysis. Data were drawn from legislation, judicial decisions, oversight reports, and peer-reviewed scholarship published between 2001 and 2025, with pre-2001 material retrieved separately to establish a baseline. A corpus of 142 sources was retained from a systematic four-stage search, and a hybrid deductive-inductive thematic analysis was conducted across four domains: surveillance and privacy, detention and due process, expression and association, and oversight and review. Results: Three principal findings emerged. First, exceptional counter-terrorism powers were normalised in all four jurisdictions, but to differing degrees once the continued legal availability of a power is distinguished from its reauthorization and its documented operational use. Normalisation was most complete in France, where emergency powers were transferred directly into ordinary law by the SILT Law 2017, and least complete in Canada, where the National Security Act 2017 partially reversed the earlier expansion. Second, formal constitutional protections were not reliable predictors of rights outcomes. The United States, despite possessing a strongly entrenched constitutional rights framework, recorded the most significant deficits in surveillance, detention, and due process, whereas the United Kingdom developed the most effective oversight architecture despite lacking a codified constitution. Third, stronger rights protection was consistently associated with oversight systems characterised by operational independence, transparency, broad mandates, and the capacity to influence policy and legal reform. Conclusion: Effective protection of civil liberties depends less on constitutional text than on the strength of accountability institutions. Oversight mechanisms that are independent, transparent, and capable of generating meaningful reform provide the most credible safeguard against executive overreach in contemporary counter-terrorism governance.
