🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

Kenyan law is a hybrid system rooted in the British common law tradition, codified in the Judicature Act (Cap 8) and reaffirmed under Article 2 of the 2010 Constitution. The seven recognised sources of law, ranked from supreme to subordinate, are: the Constitution of Kenya 2010, Acts of Parliament, delegated legislation, judicial precedent, customary law, Islamic law, and English law as it stood on 12 August 1897.

The doctrine of binding precedent (stare decisis) requires lower courts to follow the ratio decidendi of higher courts within Kenya’s hierarchy. Obiter dicta are persuasive, never binding. Kenya’s court hierarchy runs: Supreme Court → Court of Appeal → High Court → Employment and Labour Relations Court / Environment and Land Court → Magistrates’ Courts and Kadhis’ Courts.

High-yield pointers:

The Supreme Court (not the Court of Appeal) is Kenya’s apex court post-2010.
Only English law as at 12 August 1897 is adopted, not subsequent English statutes.
Substantive law defines rights; procedural law governs how they are enforced.

Classification of Law

Kenyan jurisprudence divides law along two principal axes. Substantive law creates, defines, or regulates rights and duties (for example, the Law of Contract Act, the Penal Code). Procedural law prescribes the machinery through which those rights are enforced (for example, the Civil Procedure Act, the Criminal Procedure Code).

A second axis separates public law from private law. Public law governs relations between the state and individuals — encompassing constitutional law, criminal law, and administrative law. Private law governs relations among individuals — including contract, tort, property, succession, and family law. The Kenya Law Aptitude paper regularly frames scenarios requiring the candidate to identify which branch governs a fact pattern.

Sources of Kenyan Law

The Constitution of Kenya 2010

Under Article 2(1) and 2(2), the Constitution is the supreme law of the Republic. Any other law inconsistent with it is void to the extent of that inconsistency. This constitutional supremacy overrides every other source in the hierarchy.

Legislation

Acts of Parliament are primary legislation enacted by the National Assembly (with Senate involvement in specified matters) and assented to by the President. Delegated legislation — statutory instruments, regulations, by-laws — is made by ministers, local authorities, or statutory bodies under powers conferred by a parent Act. It has the force of law but is subordinate to, and can be challenged for ultra vires against, the enabling Act.

Judicial Precedent

The Judicature Act (Cap 8, section 3) makes judicial precedent a formal source of law. Under stare decisis, the ratio decidendi — the legal principle upon which a case was decided — binds lower courts and (generally) courts of coordinate jurisdiction. Decisions of the Supreme Court bind all lower courts; the Court of Appeal binds the High Court and subordinate courts unless sitting en banc to overrule itself.

Customary and Islamic Law

Customary law applies only where the parties are subject to it, and must conform to the Constitution and any written law (Article 2(4) read with section 2(7) of the Judicature Act regarding repugnancy). Islamic law is applied by Kadhis’ Courts in matters of Muslim personal status, marriage, divorce, and inheritance, where the parties are Muslims.

Source	Binding Force	Constitutional Limit
Constitution 2010	Supreme	N/A
Acts of Parliament	Binding	Must conform to Constitution
Delegated legislation	Binding if intra vires	Ultra vires struck down
Judicial precedent	Binding on lower courts	Subject to Constitution
Customary / Islamic	Applicable to subject parties	Repugnancy / constitutional test

Common Exam Patterns

Questions test: (i) ranking the sources, (ii) identifying which court binds which, (iii) distinguishing ratio from obiter, and (iv) stating the 12 August 1897 cutoff for adopted English law.

Persuasive authority versus binding precedent. Decisions of the High Court bind magistrates but are persuasive on other High Court judges. The High Court has unlimited original jurisdiction in civil and criminal matters under Article 165(3) of the Constitution, but its decisions do not bind another High Court judge — only the Court of Appeal and Supreme Court do. Decisions of foreign courts (English Court of Appeal post-1897, Indian, South African, Nigerian) are persuasive only.

Per incuriam and overruling. A precedent reached per incuriam (without regard to a binding authority) may be disregarded by a court that would otherwise be bound. The Supreme Court and Court of Appeal may overrule their own earlier decisions in defined circumstances; the Supreme Court’s 2019 practice direction formalised the criteria for revisiting precedent.

Customary law repugnancy test. Under the Judicature Act, customary law is inapplicable where it is “repugnant to justice and morality” or inconsistent with any written law. Post-2010, the constitutional equality and non-discrimination clauses have tightened this test considerably — customary rules on succession and gender have been struck down for inconsistency with Article 27.

Connection to Adjacent Topics

Mastery of Topic 4 is the gateway to constitutional law (supremacy clauses, Article 259 interpretation), administrative law (judicial review grounds), criminal procedure (jurisdiction of subordinate courts), and customary and personal law. Nearly every fact-pattern question in the aptitude paper assumes the candidate can correctly attribute a dispute to the right source and the right court.

Common Mistakes Examiners Exploit

Citing the Court of Appeal as the apex court — pre-2010 confusion that costs marks immediately.
Asserting that all English common law binds Kenya — only the 12 August 1897 snapshot, subject to statutory modification.
Treating delegated legislation as primary law — it is challengeable, amendable, and subordinate.
Confusing ratio decidendi with obiter dicta when summarising a case.

Practice Prompts

Mini fact-pattern: “A 1965 English House of Lords decision conflicts with a 2015 Kenyan Court of Appeal ruling on the same point of contract law. Which prevails in a Kenyan magistrates’ court, and why?”
Target skill: hierarchy of precedent; the 1897 cutoff rule.
Short argument: “A customary rule of a community denies daughters the right to inherit clan land. May the rule be applied by a Kenyan court today? Construct a two-paragraph reasoning, citing Article 2 of the Constitution and the Judicature Act.”
Target skill: repugnancy doctrine and constitutional supremacy over customary law.
