THE JUSTIFICATION OF PUNISHMENT IN CRIMINAL LAW: RETRIBUTION VS REHABILITATION

Abstract

Punishment remains one of the central instruments through which criminal law responds to wrongdoing, protects social order, and expresses the authority of the state. Its justification, however, has remained deeply contested. Two of the most influential approaches are retribution and rehabilitation. The paper explains both concepts. This article examines the justification of punishment in criminal law by analysing the theoretical foundations, strengths, and limitations of retributive and rehabilitative punishment, with particular attention to Nigerian criminal justice. The article adopts a doctrinal research method, drawing on statutes, case law, textbooks, journal articles, and policy materials. It argues that neither retribution nor rehabilitation, standing alone, is sufficient to meet the complex objectives of punishment in a modern society. Retribution is necessary because it sustains moral accountability, proportionality, public confidence, and respect for victims. Rehabilitation is equally necessary because it addresses criminogenic needs, reduces recidivism, and promotes the offender’s return as a productive member of society. The article concludes that Nigerian criminal justice should adopt a balanced penal philosophy that combines proportionate punishment with credible rehabilitation. It recommends stronger implementation of the Administration of Criminal Justice Act 2015, among others.
