A retired judge of the Federal Capital Territory of Nigeria examines the most common aspects of criminal law used in Nigerian courtrooms. They are: offences against public order; breaches of peace; corruption and abuse of office; offences relating to the administration of justice; offences against morality; idle and disorderly persons; rogues and vagabonds; assaults; homicides; stealing and like offences; forgery and false accounting; and offences against liberty. The final chapter deals entirely with the Corrupt Practices and Other Related Offences Act, 2000.
