Cybercrime Law and Digital Rights: An Analysis of the Cybercrimes Prohibition Act 2015 and Its Application to Online Speech in Nigeria

The Cybercrimes (Prohibition, Prevention, etc.) Act 2015 and its 2024 amendment represent Nigeria's primary legislative response to the growing challenge of online criminal activity, encompassing offences ranging from computer fraud to online harassment. However, certain provisions of the Act, particularly those concerning offensive online communications, have been criticised for criminalising constitutionally protected speech and suppressing online political dissent. This study examines the application of the Cybercrimes Act to online speech in Nigeria from 2015 to 2023, evaluating the tension between cybercrime regulation and freedom of expression under Section 39 of the 1999 Constitution. A doctrinal methodology is applied, reviewing the Cybercrimes Act 2015, the 2024 amendment provisions, judicial decisions involving online speech prosecutions, and reports from civil society organisations including Paradigm Initiative Nigeria and Article 19. The study analyses selected cases in which journalists, activists, and social media users were prosecuted under the Act. Available digital rights literature identifies Section 24 of the Act on offensive electronic communications as the provision most frequently deployed against political speech. The Proportionality Test in Human Rights Law and the International Covenant on Civil and Political Rights Article 19 framework provide the normative reference. Findings support recommendations for legislative reform to insert necessity and proportionality standards into the Act's speech offence provisions.
