This book examined legal causation in homicide cases in Nigeria with particular focus on the "year and a day rule", "omission as actus reus" and the "last seen doctrine". The book observed that the year and a day rule had been abolished in England from where it originated and accordingly recommended for its abolition in Nigeria. It was also observed that though a crime could be committed by omission, such a rule or principle should be sparingly applied in homicide cases. The rigid and sacrosanct manner in which the Nigerian courts apply the last seen doctrine was frowned at for placing a "reverse burden" on persons accused of the offence of murder in violation of their constitutional rights of presumption of innocence and silence in the face of criminal allegations.
