The practical rule when choosing a court

What original jurisdiction means in practical terms

Original jurisdiction is the power of a court to receive a case at the beginning and determine it on the evidence and law. A court exercising original jurisdiction may hear witnesses, examine documents, rule on objections, decide facts and deliver the first judgment. This is what people ordinarily mean when they say that a court conducts a trial.

Appellate jurisdiction is different. An appellate court normally reviews a decision already made by another court. It asks whether the lower court applied the law correctly, followed a fair procedure and reached a conclusion supported by the record. An appellate court may sometimes receive limited additional evidence or remit a case for a new hearing, but an appeal is not simply a second opportunity to start the same case from zero.

The important point for an ordinary court user is that a court's position in the hierarchy does not by itself answer whether it can try a case. A Supreme Court may have narrow original jurisdiction in a constitutional or electoral dispute. A High Court may try a serious criminal case directly and also hear appeals from a magistrate. A primary or county court may be the usual first court for everyday disputes, even with smaller limits. The correct starting point depends on the Constitution, statute, subject, value or seriousness, place and sometimes the parties.

The comparison covers the eight Partner States listed by the official East African Community as at 19 September 2026. The EAC is a regional organisation, not a replacement for national judiciaries. The East African Court of Justice is a separate regional court under the EAC Treaty, not a national trial court.

Burundi's ordinary courts and specialised jurisdictions

Burundi's court system reflects a civil-law structure and uses French names in many official legal materials. The 2018 Constitution places the Supreme Court at the top of the ordinary judicial order and recognises a separate Constitutional Court. The Constitution's provisions on the judiciary, read with the organic legislation on the organisation, functioning and jurisdiction of courts, provide the framework for the ordinary courts, courts of appeal and lower local courts.

Court structure: Constitutional Court and Supreme Court at the top; Courts of Appeal below them in their respective jurisdictions; Tribunaux de Grande Instance for more substantial first-instance civil and criminal work; and Tribunaux de Résidence for local first-instance disputes. Commercial, administrative, labour and military matters may be assigned to specialised jurisdictions under legislation.

For an ordinary dispute, the Tribunal de Résidence is often the entry point for matters within its statutory limits. The Tribunal de Grande Instance is a more substantial trial court and may hear matters too serious or valuable for a residence court. A Court of Appeal generally reviews a first-instance judgment. The Supreme Court mainly controls legality and hears matters assigned by law; it is not the ordinary place to file a new contract, land or criminal case.

Burundi also illustrates why “highest court” and “court of first instance” are not opposites. The Constitutional Court has original constitutional work, including review of legislation in constitutional circumstances. The High Court of Justice, composed of the Supreme Court and Constitutional Court sitting together, has the exceptional jurisdiction described in Articles 239 to 242 over specified senior officials. That is original jurisdiction, but not the normal public trial route.

Burundian decisions may be identified by the names of the parties, the court or chamber, the case number and the date. French expressions such as Cour Suprême, Cour Constitutionnelle, Tribunal de Grande Instance and Tribunal de Résidence identify the institution; a file number identifies the particular proceeding. Because publicly accessible reporting is less uniform than Kenya's or Tanzania's, a researcher should preserve the full caption and date rather than reducing the reference to an unexplained abbreviation.

The Democratic Republic of the Congo's three judicial orders

The Democratic Republic of the Congo has a more visibly divided constitutional design. The 2006 Constitution separates the judicial order, the administrative order and the Constitutional Court. Article 153 places civil and military courts and tribunals under the Court of Cassation. Articles 154 and 155 provide for the administrative order headed by the Conseil d'Etat, while the Constitutional Court has its own constitutional mandate. Organic Law Number 13/011 B of 11 April 2013 supplies the principal framework for the organisation, functioning and competence of courts in the judicial order.

Court structure: Constitutional Court for constitutional questions; Conseil d'Etat for the administrative order; Cour de Cassation for the judicial order; Courts of Appeal beneath the Cour de Cassation; Tribunaux de Grande Instance and Tribunaux de Paix as ordinary first-instance courts; and military jurisdictions for military offences and persons covered by law.

The Tribunal de Paix is the familiar lower trial court for many ordinary civil and criminal matters. The Tribunal de Grande Instance handles more serious matters and matters allocated to it by law. A Court of Appeal can have appellate jurisdiction and, in particular classes of proceedings, an original role. The Cour de Cassation is not a general third trial court. Its ordinary task is to review legal error, jurisdiction and procedure rather than rehear every witness. Nevertheless, the Constitution gives it original and final jurisdiction over specified offences involving senior public officials. That exceptional jurisdiction is a reminder that the word “original” describes the way a case begins, not the court's rank alone.

The administrative route should be kept separate from a private civil claim. A challenge to an administrative act may belong in the administrative order, not before a Tribunal de Paix simply because it is nearby. The Constitution and 2013 organic legislation must be read together as institutions develop.

Congolese case references commonly retain the French vocabulary of the court and identify the type of proceeding, the file number and the date. A reference such as “R. Const.” may indicate a constitutional matter in a research database, while “RP” or another docket prefix may be used for a criminal file. These prefixes are not safe to guess in isolation. The full case caption, court, chamber, number and date should always accompany the shortened reference.

Kenya's superior and subordinate trial courts

Kenya provides one of the clearest constitutional examples of several courts exercising original jurisdiction at the same time. Chapter Ten of the Constitution of Kenya, 2010 distinguishes superior courts from subordinate courts. Article 163 establishes the Supreme Court, Article 164 the Court of Appeal, Article 165 the High Court, Article 162 the Employment and Labour Relations Court and the Environment and Land Court, and Article 169 the subordinate courts.

Court structure: Supreme Court; Court of Appeal; High Court, including its subject-matter divisions; Environment and Land Court and Employment and Labour Relations Court; then Magistrates' Courts, Kadhis' Courts, Courts Martial and other courts or tribunals authorised by the Constitution or legislation.

The High Court has unlimited original jurisdiction in criminal and civil matters under Article 165, subject to the specialised jurisdiction assigned to the Environment and Land Court and Employment and Labour Relations Court. It also supervises subordinate courts and quasi-judicial bodies. The specialised superior courts conduct first-instance hearings in their fields. Magistrates' Courts remain usual trial courts for many criminal cases and civil claims within statutory limits. Kadhis' Courts have narrower original jurisdiction in Muslim-law questions of personal status, marriage, divorce and inheritance where constitutional conditions are met.

The Supreme Court is mostly appellate. Its important original jurisdiction is exclusive jurisdiction over a dispute concerning the election of the President under Article 163(3)(a). It is therefore inaccurate to tell a member of the public that every case should begin in the Supreme Court because it is the highest court. In most disputes, filing there would be a jurisdictional error.

Kenyan neutral citations make the structure visible. In Saisi and 7 others v Director of Public Prosecutions and 2 others, Petition 39 and 40 of 2019 (Consolidated), [2023] KESC 6 (KLR), “KESC” means Kenya Supreme Court and “KLR” means Kenya Law Reports. “KECA” identifies the Kenya Court of Appeal and “KEHC” the High Court of Kenya. The year and number normally identify the electronic decision in that court's series, while the case number tells the reader how the matter was filed. A report citation and a file number are related but not interchangeable.

Rwanda's ordinary and specialised courts

Rwanda's current structure is set out clearly by Article 153 of the Constitution of Rwanda of 2003 revised in 2023 and by legislation determining the organisation, functioning and competence of courts. The Rwanda Judiciary describes two categories: ordinary courts and specialised courts.

Court structure: Supreme Court; Court of Appeal; High Court and its chambers; Intermediate Courts; Primary Courts; then specialised Commercial Courts and Military Courts, consisting of the Military Tribunal and Military High Court.

Primary Courts rule on original civil and criminal matters within legal limits. The twelve Intermediate Courts have both original and appellate jurisdiction in civil, criminal and administrative matters. The High Court, based in Kigali with chambers elsewhere, also has original, appellate and supervisory work. The Commercial Court begins commercial cases, while the Commercial High Court hears appeals. The Military Tribunal is first instance and the Military High Court is appellate.

The Court of Appeal is not a general first-instance court: its ordinary function is to hear appeals from the High Court, Commercial High Court and Military High Court. The Supreme Court is the highest national court and primarily ensures uniform interpretation and finality. A person should therefore identify the dispute first, then ask whether the law directs it to a Primary Court, Intermediate Court, High Court or specialised court.

Rwanda's judgments are commonly located through the official portal of Rwandan laws and case law. Case references usually preserve the court's abbreviation, the case or appeal number and the year. “CA” commonly signals the Court of Appeal in a case number or caption, while “Commercial” or “Military” identifies the relevant specialised order. The safest practice is to copy the complete official reference from the Judiciary or Amategeko portal because the number may carry more information than a short English abbreviation.

South Sudan's constitutional court structure

The Transitional Constitution of the Republic of South Sudan, 2011, establishes an independent Judiciary and gives the constitutional structure in Articles 123 to 132. Article 124 lists the Supreme Court, Courts of Appeal, High Courts, County Courts and other courts or tribunals established by law.

Court structure: Supreme Court; Courts of Appeal; High Courts; County Courts; and other national, state or customary courts created under the Constitution and legislation.

County Courts are the most immediate ordinary trial forum in the constitutional hierarchy, although their exact competence is set by law. High Courts hear matters assigned to them at first instance and appeals from County Courts. Courts of Appeal review High Court decisions. The Supreme Court is the final judicial instance but also has important original jurisdiction. Under Article 128 it may decide constitutional disputes, disputes between states and disputes between the National Government and a state, and exercise constitutional and criminal jurisdiction in specified circumstances.

South Sudan's structure requires care because national, state and customary jurisdictions may overlap. A case involving customary law, land, family relations or a state institution should not be filed merely because a court building is nearby. The Constitution, Judiciary Act, customary-court legislation and applicable state law must be checked together.

Published South Sudanese decisions are often identified by the parties, the court, the case number, the type of proceeding and the date rather than by one consistently used national neutral-citation series. “SC” may mean Supreme Court and “HC” High Court in a local reference, but those letters should be read with the full caption. A complete citation is more reliable than an unexplained short form.

Somalia's federal and member state courts

Somalia is constitutionally different from the unitary systems described above. The Provisional Constitution of the Federal Republic of Somalia, 2012, organises judicial authority through the Constitutional Court, Federal Government level courts and Federal Member State level courts. Articles 105 to 109 also connect the appointment and administration of federal judges with the Judicial Service Commission.

Court structure: Constitutional Court; federal courts established by federal law, including first-instance and appellate levels; and courts of each Federal Member State established under the federal constitutional settlement and applicable state law.

The federal arrangement means that “the Somali court of first instance” is not one institution for every dispute. An ordinary case may begin in a federal trial court or Member State court, depending on the parties, subject, territory and legislation. The Constitutional Court is an original forum for constitutional questions, not an ordinary commercial, land or criminal trial court. Federal and Member State relations remain under legal and institutional reform, so current enabling laws and territorial competence must be checked before filing.

Somali case citations are most safely written with the full name of the court, case number, parties and date. Where a decision is reported in Somali or Arabic, the language and translated title should be kept together. A docket number is not a neutral citation by itself. Researchers should avoid importing Kenyan or Ugandan abbreviations into Somali judgments unless the issuing court or database has used them.

Tanzania's Union, Mainland and Zanzibar arrangement

Tanzania needs a separate explanation because it is a Union with distinct Mainland and Zanzibar judicial arrangements. The Constitution of the United Republic of Tanzania, 1977, establishes the Court of Appeal of the United Republic and the High Court of Tanzania for the Mainland jurisdiction. The Magistrates' Courts Act and related laws organise Resident Magistrates' Courts, District Courts and Primary Courts. The Judiciary's current court information describes Primary Courts as the lowest level in the hierarchy.

Court structure on the Mainland: Court of Appeal of the United Republic; High Court of Tanzania, including its specialist divisions; Courts of Resident Magistrates; District Courts; and Primary Courts. Zanzibar maintains the High Court of Zanzibar and its own subordinate and Kadhi court arrangements under the Constitution of Zanzibar and Zanzibar legislation. The Union Constitution also provides for a Special Constitutional Court for disputes between the Union Government and the Revolutionary Government of Zanzibar.

Primary Courts and District Courts are common first-instance forums for local civil and criminal matters within statutory jurisdiction. Resident Magistrates' Courts hear matters assigned by law. The High Court has original jurisdiction outside subordinate-court jurisdiction and operates Commercial, Land and Labour divisions. It can therefore be a trial court while also hearing appeals and revisions. The Court of Appeal is mainly appellate.

Tanzanian electronic citations show the court and the year clearly. In Ezekiel Joseph at Helman v Republic, Criminal Case 8 of 2022, [2022] TZHC 9918, “TZHC” means Tanzania High Court. “TZCA” is commonly used for Tanzania Court of Appeal decisions. “TLR” may refer to the Tanzania Law Reports. The number in brackets after the year is usually the electronic decision number, while “Criminal Case” or “Civil Case” identifies the trial file.

Uganda's High Court and lower trial courts

Article 129 of the Constitution of the Republic of Uganda, 1995, lists the Supreme Court, Court of Appeal, High Court and subordinate courts established by Parliament. Article 139 gives the High Court unlimited original jurisdiction in all matters, together with appellate and other jurisdiction conferred by the Constitution or law. The Judicature Act and the Magistrates Courts Act provide the working framework for the courts below and alongside the High Court.

Court structure: Supreme Court; Court of Appeal, which also sits as the Constitutional Court; High Court and its divisions; Chief Magistrates' and Magistrates' Courts; Qadhis' Courts; Local Council Courts; and specialised tribunals or courts created by legislation.

The High Court may conduct a first trial in a serious criminal case, a constitutional or administrative matter, a commercial dispute, a land dispute or another matter within its jurisdiction. Its divisions help organise this work but do not necessarily create separate constitutional courts. Magistrates' Courts conduct a very large share of ordinary criminal and civil trials within statutory limits. Their decisions generally move to the High Court on appeal. Local Council Courts and Qadhis' Courts have narrower original jurisdiction defined by law.

Ugandan citations show the value of reading every part of a reference. Male H. Mabirizi and others v Attorney General and others, Constitutional Appeals 2, 3 and 4 of 2018, [2019] UGSC 102, uses “UGSC” for Uganda Supreme Court. “UGCC” identifies a Constitutional Court decision, while “UGCommC” identifies the High Court Commercial Division. “ULR” means Uganda Law Reports. Older regional authorities may use “EACA”, meaning East African Court of Appeal, as in Bukenya v Regina, [1952] EACA 235. That case is an historical appellate authority, not a current Ugandan trial-court citation.

How East African case citations are read

A case citation usually answers four questions: who were the parties, what was the case or appeal number, which court decided it and where can the decision be found. A modern citation may contain the case name, year in square brackets, court code, sequential decision number, law-report abbreviation and date. For example, “[2023] KESC 6 (KLR)” identifies Kenya's Supreme Court, decision 6 in the 2023 electronic sequence and the Kenya Law Reports.

The case number is not the same as the report citation. “Petition 39 and 40 of 2019 (Consolidated)” tells us how the dispute was filed and that proceedings were combined. “KESC 6” locates the later judgment in a reporting sequence. A court-file number can remain the same even where a matter is appealed and receives a new appellate number. The appeal court's reference should therefore be added to, not substituted blindly for, the trial record.

Abbreviations should also be read in context. “SC” may mean Supreme Court, “CA” Court of Appeal, “HC” High Court, “CC” Constitutional Court and “C” Court. But the first letters may be national rather than universal: KEHC and UGSC identify Kenya and Uganda, while TZHC identifies Tanzania. “KLR”, “ULR” and “TLR” describe report series, not courts. “EACA” identifies the former regional appellate court and is not proof that a current national case was heard by an East African institution.

The practical rule when choosing a court

The safest starting question is not “Which is the highest court?” It is “Which law gives this court power to hear this type of case first?” That directs attention to subject, territory, value, seriousness, parties and any specialised forum. A land claim may go to a land court, employment claim to a labour court, Muslim personal-law dispute to a Kadhi court, constitutional challenge to a constitutional court or referring lower court, and ordinary criminal charge to a magistrate or county court.

Original jurisdiction is the doorway through which evidence first enters the judicial system. Appellate jurisdiction is the route by which a higher court reviews what happened at that doorway. Understanding the difference makes court structures less intimidating, helps a reader read a case citation without guessing and reduces the practical risk of filing a legitimate claim in the wrong forum.
