Boundaries of Jurisdiction: Chengo and Kenya Courts

Kenya has three superior courts at the same hierarchical level that do not exercise the same jurisdiction. Republic v Chengo is the case that makes this distinction easiest to understand. The High Court, the Environment and Land Court, and the Employment and Labour Relations Court are equal in status, but equality of rank does not make their judges interchangeable.

The practical question is important because filing in the wrong court can waste years. A dispute may contain constitutional language, land questions, employment questions and ordinary civil claims at the same time. Chengo does not solve every mixed case automatically, but it gives the starting rule: identify the court's constitutional and statutory field before asking whether the case is important, urgent or convenient to hear there.

The unusual mixed bench that created the case

Republic v Chengo & 2 others, Petition 5 of 2015 [2017] KESC 15 (KLR), arose from an effort to reduce a backlog of criminal appeals. During a Judicial Service Week in 2013, judges from specialised courts were assigned to sit with High Court judges. At Malindi, a High Court judge and a judge appointed to the Environment and Land Court jointly heard criminal appeals.

The Court of Appeal held that the Environment and Land Court judge lacked authority to determine criminal appeals reserved to the High Court. The Director of Public Prosecutions appealed to the Supreme Court.

The constitutional question was deceptively simple. Article 162(2) describes the specialised courts as having the status of the High Court. Did that equal status allow a judge appointed to one of those courts to exercise the High Court's criminal appellate jurisdiction? The Supreme Court answered no.

Status and jurisdiction are different legal ideas

The Supreme Court held that status concerns hierarchical standing, while jurisdiction concerns the sphere of legal authority. The three courts occupy equal rank, but the Constitution deliberately assigned different subject matter to them.

Article 165 establishes the High Court and gives it broad original civil and criminal jurisdiction, subject to the exclusions in Article 165(5). Article 162(2) requires specialised courts for employment and labour relations and for environment, land use, occupation and title. Parliament then defined those specialised jurisdictions through the Employment and Labour Relations Court Act and the Environment and Land Court Act.

Section 13 of the Environment and Land Court Act gives that court original and appellate jurisdiction over disputes concerning environment and land, including title, tenure, land administration, public and private land and related instruments. Section 12 of the Employment and Labour Relations Court Act gives the labour court exclusive original and appellate jurisdiction over the employment and labour disputes assigned to it. Neither statute gives those judges a general criminal appellate jurisdiction.

Why the judge's appointment matters

Chengo also treated judicial appointment as legally significant. Judges are not appointed to an undifferentiated pool of superior-court power. A judge is appointed and sworn to a particular court, and the jurisdiction exercised follows that constitutional office.

That is why administrative assignment could not solve the problem in Chengo. The Chief Justice had a legitimate objective in reducing backlog, but administrative convenience cannot expand jurisdiction fixed by the Constitution and legislation. Nor can the parties' consent cure the defect.

The principle protects litigants from well-intentioned but unauthorised adjudication. A judgment from a bench that lacks jurisdiction may be a nullity even where the hearing was fair, the judges acted in good faith and the outcome appears substantively reasonable.

The rule remains active in current cases

Chengo is not a dormant structural decision. Kenyan courts continued to rely on it in 2025 when deciding whether disputes belonged in the High Court, Environment and Land Court or Employment and Labour Relations Court.

In Republic v Attorney General; Chege, decided in June 2025, the High Court relied on Chengo while examining whether an employment-related judicial review dispute belonged in the specialised labour court. In Republic v Nairobi City County Government; Amiha Investments, decided in April 2025, the High Court similarly treated the subject matter as falling within the Environment and Land Court and transferred the case after concluding that the High Court lacked jurisdiction.

These cases show the modern practical effect of Chengo. Constitutional remedies such as judicial review do not automatically belong to the High Court if the underlying subject matter is one that the Constitution and statute assign to a specialised court.

Constitutional questions can still be decided by specialised courts

One common misunderstanding is that only the High Court may interpret the Constitution. Chengo does not support that proposition. The specialised courts may determine constitutional questions that arise within disputes properly falling inside their subject-matter jurisdiction.

An employment case does not become an ordinary High Court case merely because the employee alleges violation of constitutional rights. A land dispute likewise does not leave the Environment and Land Court merely because the claimant asks for declarations or judicial review-type relief. The decisive inquiry is the real nature of the controversy.

This prevents strategic pleading from defeating specialisation. At the same time, it requires careful classification where claims genuinely overlap. Lawyers should identify the dominant or essential dispute and the statutory jurisdiction connected to the relief requested rather than selecting a court solely from the constitutional provisions cited in the pleadings.

International standards support legality, but do not allocate Kenyan jurisdiction

The United Nations Basic Principles on the Independence of the Judiciary state, among other things, that everyone has the right to be tried by ordinary courts or tribunals using established legal procedures. The Principles are not the source of the jurisdiction of Kenya's High Court, Environment and Land Court or labour court.

Their relevance is broader. They reinforce the rule-of-law idea that adjudicative power should be exercised through legally established courts and procedures. In Kenya, however, the precise allocation of power is determined by Articles 162 and 165 of the Constitution and the statutes enacted under them.

A practical court-selection method

Before filing, counsel should identify the source of jurisdiction and then classify the essential subject matter. If the case is fundamentally about title, occupation, use or administration of land, section 13 of the Environment and Land Court Act should be considered. If it arises from an employment or labour relationship, section 12 of the Employment and Labour Relations Court Act is central. If the matter falls outside the specialised fields and within Article 165, the High Court may be the proper superior court.

The same analysis should be repeated for each major remedy. A pleading that combines claims should explain why one court can lawfully determine the complete controversy, or whether claims must be separated or otherwise handled through a lawful procedural mechanism.

Judicial administrators must apply the same discipline when assigning judges. Backlog, workload and convenience are serious practical concerns, but Chengo requires solutions that respect the judicial office and jurisdiction to which each judge was appointed.

Why Chengo still matters

Chengo gives substance to the constitutional idea of specialisation. The specialised courts were not created as departments of the High Court. They were given equal standing so that employment and land disputes could be handled by courts of full superior-court status while remaining within defined fields.

Its lesson is therefore not only "file in the correct court." It is that lawful adjudication depends on both the correct institution and a properly constituted bench. Equal rank does not erase the legal boundaries between judicial offices.

For an ordinary litigant, that distinction can determine whether years of litigation produce an enforceable judgment or a jurisdictional nullity. The safest starting point is to ask what the dispute is really about and which constitutional and statutory provisions give a particular court power to decide it.
