TOPIC 1: HISTORICAL DEVELOPMENT AND SOURCES OF CRIMINAL LAW
1. Summary of Kenya Criminal law
Kenya criminal law is the body of national law relating to crime in Kenya. Broadly speaking, it
defines as criminal such human conduct as threatens, harms or endangers the safety and welfare
of people. It also sets out the punishment to be imposed on persons who engage in such conduct,
provided they have criminal capacity and act unlawfully and with a guilty mind.
In the definition of Van der Walt et al, a crime is "conduct which common or statute law
prohibits and expressly or impliedly subjects to punishment remissible by the state alone and
which the offender cannot avoid by his own act once he has been convicted." Crime involves the
infliction of harm against society. The function or object of criminal law is to provide a social
mechanism with which to coerce members of society to abstain from conduct that is harmful to
the interests of society.
Classification of Law is usually in three/: Criminal, Public and Civil.
Criminal law (which is to be distinguished from its civil counterpart) forms part of the public law
of Kenya, as well as of the substantive law (as opposed to the procedural). In Kenya, as in most
adversarial legal systems, the standard of evidence required to validate a criminal conviction is
proof beyond a reasonable doubt. The sources of Kenya criminal law are to be found in the
common law, in case law and in legislation.
