A Comparative Legal Analysis of Self-Defense in Nigeria and the United States

Abstract

Self-defence remains one of the most fundamental doctrines in criminal

law, grounded in the principle of necessity and the instinct of self-
preservation. This article undertakes a comparative legal analysis of the

doctrine of self-defence as it operates within the legal systems of Nigeria
and the United States. The study examines the statutory frameworks,
judicial interpretations, and doctrinal principles governing the use of
force in both jurisdictions. Doctrinal methodology is adopted, relying on
the analysis of statutes, case law, and relevant academic literature. The
article identifies key elements of self-defence, including imminence,
necessity, proportionality, and the duty to retreat, and evaluates how
these elements are applied within each system. Particular attention is
given to the codified structure of Nigerian law under the Criminal Code
and Penal Code, as well as the diverse and state-based approach of the
United States, including doctrines such as the “Stand Your Ground” rule
and the “Castle Doctrine.” The study finds that while both jurisdictions
recognize self-defence as a complete legal justification, Nigeria adopts a
more restrictive and cautious approach, whereas the United States,
depending on the state, often provides broader protections for the use of
defensive force. The article concludes that clearer statutory guidance,
improved judicial consistency, and increased public awareness are
necessary to ensure that the doctrine effectively balances the protection
of human life with the right to personal security.
