Sources of Kenyan Law

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

Law in the Kenyan context is a body of rules enforced by the state to regulate conduct and resolve disputes. The Constitution of Kenya 2010 is the supreme law; any inconsistent rule is void (Article 2). Recognised sources of Kenyan law include the Constitution, Acts of Parliament, subsidiary legislation, Kenyan case law, received English law (under the Judicature Act, Laws of Kenya Act, and Magistrate’s Courts Act, capped at 12 August 1897), customary law, Islamic law, and equity doctrines. Precedent (stare decisis) binds lower courts to the ratio decidendi of higher-court decisions, while obiter dicta are merely persuasive. A valid contract needs offer, acceptance, consideration, intention, capacity, and free consent. Bilateral mistake on a fundamental fact voids a contract; a unilateral mistake generally does not unless the other party knew or ought to have known.

Sources of Kenyan Law

The hierarchy begins with the Constitution of Kenya 2010, which under Article 2 binds all persons and state organs. Below it sit Acts of Parliament enacted by the National Assembly and Senate, and subsidiary legislation (regulations, rules, by-laws) made under enabling statutes. Kenyan case law from superior courts — the Supreme Court, Court of Appeal, High Court, and Employment and Environment & Land Court — supplies binding precedent. Received English law is part of Kenyan law only to the extent it applies on 12 August 1897, subject to local modification. African customary law applies where the parties are subject to it, provided it is not repugnant to justice or morality (Judicature Act, s. 3). Islamic law governs family and inheritance matters for Muslims under the Kadhis’ Courts Act. Equity doctrines (trusts, estoppel, specific performance) supplement common law where the common law remedy is inadequate.

Classification of Law

Public law concerns the state and individuals (constitutional, criminal, administrative); private law governs relations among persons (contract, tort, property, family). Substantive law creates rights and duties; procedural law prescribes how they are enforced. Municipal law operates within Kenya; international law governs state relations. Common law, statute, and customary law are the three principal origins.

Contract Formation

Under the Law of Contract Act (Cap 23, Laws of Kenya) and judicial precedent, a contract requires (1) offer, (2) acceptance mirroring the offer, (3) consideration of value, (4) intention to create legal relations, (5) capacity (age of majority, sound mind), and (6) free consent free from misrepresentation, duress, undue influence, mistake, or illegality.

Mistake Doctrine

A unilateral mistake renders a contract void only if it relates to a fundamental term and the non-mistaken party knew or ought reasonably to have known of the error (Hartog v Colin & Shields). A bilateral mistake — both parties mistaken on a basic fact or the nature of the contract (e.g., Smith v Hughes, 1871) — voids the agreement because there is no consensus ad idem.

Legal Reasoning Techniques

Deductive reasoning moves from a stated rule (major premise) to a fact pattern (minor premise) to a conclusion. Inductive reasoning derives a general principle from multiple authorities. Analogical reasoning applies binding precedent to a new fact pattern; distinguishing identifies a material factual or legal difference that removes the binding force. The ratio decidendi is the rule of law on which the decision turns; everything else is obiter dictum.

Edge Cases and Doctrinal Subtleties

The received English law doctrine does not automatically import later English statutes or decisions; post-1897 English common law applies only when Kenyan courts have adopted it. Customary law must be proved as a fact unless judicially noticed, and a court may refuse to apply any rule that is “repugnant to justice and morality” or incompatible with the Constitution. Equity’s priority over common law (Judicature Act, s. 14) means equitable remedies like injunctions and specific performance override conflicting common-law outcomes where they concur.

Mistake in Practice

In Great Peace Shipping Ltd v Tsavliris Salvage (International) Ltd (2002), the English Court of Appeal refused rectification for an inadvertent mistake on subject-matter identity, emphasising that a contract void for mutual mistake requires both parties to have materially misunderstood the same essential term at the time of contracting — not merely a unilateral error. Kenyan courts have applied similar reasoning in commercial disputes heard by the Commercial Division of the High Court.

Adjacent Connections

Precedent interacts with statutory interpretation through the literal rule, golden rule, and mischief rule (Heydon’s Case, 1584). Hypothetical reasoning — testing a rule against assumed facts — is the backbone of problem-question analysis in the Kenya Law Aptitude paper and is examined through scenario-style MCQs that present a client situation followed by four legal propositions.

Common Mistakes

Confusing ratio decidendi with obiter dictum leads to mis-identifying whether a case binds; binding force attaches only to the former. Treating English case law after 1897 as automatically binding is incorrect — Kenyan courts are free to depart. Assuming consideration can be inadequate to invalidate a contract is also wrong; inadequacy alone does not void consent (except in unconscionability cases).

Practice Prompts

A Kenyan farmer and a buyer agree on the sale of “the cattle in the field,” but on delivery the buyer discovers the farmer owned no cattle. Discuss the validity of the contract, applying the doctrine of bilateral mistake.
The High Court remarks in passing that a custom is unconstitutional. In a later case, a lower court relies on that remark. Identify which part of the earlier decision is binding and which is persuasive, and explain the rule of precedent that applies.
