Courts
What is the difference between a trial court and an appellate court, and how far does an appeal actually go?
Trial courts generally establish facts; appellate courts generally review decisions. Both halves need qualifying: appeal is neither a fresh trial nor a review of law alone as a universal rule, and how far it goes is set by each system.
In short
The working distinction is that a trial court decides what happened and what follows from it, while an appellate court examines a decision that has already been made. That is a useful starting point and it is not a rule — the second half in particular varies more than almost any other feature of court systems.
- Trial courts generally
- Hear evidence, resolve disputed facts, apply law to the facts found, and decide the case at first instance. This is where witnesses appear and where the record is made. Ireland’s District and Circuit Courts, Japan’s district and summary courts and the Netherlands’ eleven rechtbanken all sit here.
- Appellate courts generally
- Examine whether the decision below was reached correctly, on the record made there. They typically do not hear witnesses afresh. Ireland’s Court of Appeal, Japan’s high courts and the Netherlands’ four gerechtshoven sit here.
Why it exists
The division exists because two different tasks need different conditions. Establishing what happened requires being in the room: seeing witnesses, handling exhibits, managing a live process. Deciding whether a decision was properly reached requires distance from all of that, and a court that sees many cases and can say what the law means across them.
AnalysisA court doing both at once would have to re-run every case to check it, which no system could sustain. So appellate courts almost everywhere work from the record rather than from the events.
How it works
The clearest evidence that scope varies is the existence of a distinct mode of review at the top. The Cour de cassation is the highest court of the judicial order in France, and describing it as "the French supreme court" invites a false equivalence with courts that re-decide cases: cassation review is directed at whether the law was correctly applied. A court can sit at the apex of a hierarchy and still not be a court that hears the case again.
Tiers also do more than one job at once. Ireland’s Circuit Court handles higher-value civil claims and more serious criminal trials, and hears appeals from the District Court — so the same court is a trial court in some cases and an appellate court in others. The categories describe functions, not buildings.
And a first-instance court may hold powers usually associated with the top of a system. Ireland’s High Court has full original jurisdiction in all matters, civil or criminal, and jurisdiction to determine the validity of any law having regard to the Constitution. Constitutional review does not necessarily belong to the apex.
Common misconceptions
Widely held beliefs that do not match how the system actually operates.
Common belief: An appeal is a new trial.
In practice: Appellate courts typically work from the record made below rather than hearing witnesses again. Where a system does provide a rehearing, that is a feature of that system’s procedure and not a general property of appeals.
Common belief: An appeal can only raise points of law.
In practice: Equally not universal. Several systems allow a broader review at the first appeal and a narrower one above it, so the scope depends on which appeal is being taken, in which system.
Common belief: Everyone has a right to appeal any decision.
In practice: Appeal rights are created by law and are bounded. Some routes require permission, some are limited to defined categories, and some decisions are final at the tier that made them.
Common belief: A court is either a trial court or an appellate court.
In practice: Ireland’s Circuit Court tries cases and hears appeals from the District Court. The distinction is between functions, and one court can perform both.
Common belief: Losing an appeal means the original decision was correct.
In practice: An appellate court decides whether the decision below can stand on the grounds argued, within its own scope of review. That is a narrower question than whether the outcome was right.
How this varies between jurisdictions
A required section on every guide. Arrangements differ between countries, and we say how.
Three questions establish what an appeal is in an unfamiliar system, and none of them can be answered from the word itself.
- Is the appellate court reviewing the record, or hearing the case again?
- May it revisit findings of fact, or only the application of law?
- Does the route require permission, and does the scope narrow at higher tiers?
Systems also differ on where the review function sits structurally. Japan’s high courts hear appeals as their principal work; Ireland created a dedicated Court of Appeal only in 2014; the Netherlands routes administrative appeals away from its ordinary appellate courts entirely.
Rights and accountability
AnalysisAppeal is the mechanism by which a court system corrects itself, and that is why it belongs in any account of why courts matter. A first-instance decision is made once, by one court, often quickly. Review is the acknowledgement built into the system that this is not always enough.
AnalysisIt is also bounded on purpose. Proceedings have to end, evidence decays, and a dispute that can be reopened indefinitely has not been resolved. Every system therefore balances correction against finality, and the appeal rules are where that balance is struck.
What we could not establish
- The scope of appeal in each system is set by that system’s procedural law, and this corpus records appeal routes as unresearched for several countries. Nothing here states what may be appealed in any particular country.
- The general descriptions below are patterns drawn from the systems in this corpus. They are not rules, and a system may allocate the work differently.

Related topics
- How are court systems structured — and is every system one pyramid?
Most descriptions show a single pyramid rising to one supreme court. Six of the twelve systems examined here have more than one hierarchy, and what usually decides the route is the nature of the dispute rather than its seriousness.
- What does a supreme court actually do — and does the name mean the same thing everywhere?
It does not. “Supreme court” covers a final appellate court, a constitutional court, both at once, and one apex among several. Some apex courts review whether the law was correctly applied rather than deciding the case again.
- Which court is legally competent to hear a particular case?
Court jurisdiction runs on several dimensions at once — territory, subject matter, tier and constitutional competence. It is a different question from where police may act, and from which institution may investigate.

Supports Art. 94(1) no. 4b and 4c (municipal complaints and complaints by associations about non-recognition as political parties), and Art. 94(4), that decisions of the Court bind the constitutional organs. Supports Art. 100(1), CONCRETE review: "If a court concludes that a law on whose validity its decision depends is unconstitutional, the proceedings shall be stayed, and a decision shall be obtained from the Land court with jurisdiction over constitutional disputes where the constitution of a Land is held to be violated or from the Federal Constitutional Court where this Basic Law is held to be violated" — that is, the ordinary court must refer and may not itself disapply the statute.

The Grundgesetz carries THREE distinct emergency regimes, and conflating them is the commonest error about it. Supports Grundgesetz Art. 35(1), (2) sentence 2: “(1) Alle Behörden des Bundes und der Länder leisten sich gegenseitig Rechts- und Amtshilfe. (2) [...] Zur Hilfe bei einer Naturkatastrophe oder bei einem besonders schweren Unglücksfall kann ein Land Polizeikräfte anderer Länder, Kräfte und Einrichtungen anderer Verwaltungen sowie des Bundesgrenzschutzes und der Streitkräfte anfordern.”. Supports Grundgesetz Art. 35(3): “(3) Gefährdet die Naturkatastrophe oder der Unglücksfall das Gebiet mehr als eines Landes, so kann die Bundesregierung, soweit es zur wirksamen Bekämpfung erforderlich ist, den Landesregierungen die Weisung erteilen, Polizeikräfte anderen Ländern zur Verfügung zu stellen, sowie Einheiten des Bundesgrenzschutzes und der Streitkräfte zur Unterstützung der Polizeikräfte einsetzen. Maßnahmen der Bundesregierung nach Satz 1 sind jederzeit auf Verlangen des Bundesrates, im übrigen unverzüglich nach Beseitigung der Gefahr aufzuheben.”. Supports Grundgesetz Art. 91(2): “(2) Ist das Land, in dem die Gefahr droht, nicht selbst zur Bekämpfung der Gefahr bereit oder in der Lage, so kann die Bundesregierung die Polizei in diesem Lande und die Polizeikräfte anderer Länder ihren Weisungen unterstellen sowie Einheiten des Bundesgrenzschutzes einsetzen. Die Anordnung ist nach Beseitigung der Gefahr, im übrigen jederzeit auf Verlangen des Bundesrates aufzuheben.”. Supports Grundgesetz Art. 87a(2), (4): “(2) Außer zur Verteidigung dürfen die Streitkräfte nur eingesetzt werden, soweit dieses Grundgesetz es ausdrücklich zuläßt. [...] (4) Zur Abwehr einer drohenden Gefahr für den Bestand oder die freiheitliche demokratische Grundordnung des Bundes oder eines Landes kann die Bundesregierung, wenn die Voraussetzungen des Artikels 91 Abs. 2 vorliegen und die Polizeikräfte sowie der Bundesgrenzschutz nicht ausreichen, Streitkräfte zur Unterstützung der Polizei und des Bundesgrenzschutzes beim Schutze von zivilen Objekten und bei der Bekämpfung organisierter und militärisch bewaffneter Aufständischer einsetzen. Der Einsatz von Streitkräften ist einzustellen, wenn der Bundestag oder der Bundesrat es verlangen.”. Supports Grundgesetz Art. 115a(1): “(1) Die Feststellung, daß das Bundesgebiet mit Waffengewalt angegriffen wird oder ein solcher Angriff unmittelbar droht (Verteidigungsfall), trifft der Bundestag mit Zustimmung des Bundesrates. Die Feststellung erfolgt auf Antrag der Bundesregierung und bedarf einer Mehrheit von zwei Dritteln der abgegebenen Stimmen, mindestens der Mehrheit der Mitglieder des Bundestages.”. Supports Grundgesetz Art. 115a(2), (3), (4): “(2) Erfordert die Lage unabweisbar ein sofortiges Handeln und stehen einem rechtzeitigen Zusammentritt des Bundestages unüberwindliche Hindernisse entgegen oder ist er nicht beschlußfähig, so trifft der Gemeinsame Ausschuß diese Feststellung mit einer Mehrheit von zwei Dritteln der abgegebenen Stimmen, mindestens der Mehrheit seiner Mitglieder. [...] (4) Wird das Bundesgebiet mit Waffengewalt angegriffen und sind die zuständigen Bundesorgane außerstande, sofort die Feststellung nach Absatz 1 Satz 1 zu treffen, so gilt diese Feststellung als getroffen und als zu dem Zeitpunkt verkündet, in dem der Angriff begonnen hat.”. Supports Grundgesetz Art. 115g: “Die verfassungsmäßige Stellung und die Erfüllung der verfassungsmäßigen Aufgaben des Bundesverfassungsgerichtes und seiner Richter dürfen nicht beeinträchtigt werden. Das Gesetz über das Bundesverfassungsgericht darf durch ein Gesetz des Gemeinsamen Ausschusses nur insoweit geändert werden, als dies auch nach Auffassung des Bundesverfassungsgerichtes zur Aufrechterhaltung der Funktionsfähigkeit des Gerichtes erforderlich ist. Bis zum Erlaß eines solchen Gesetzes kann das Bundesverfassungsgericht die zur Erhaltung der Arbeitsfähigkeit des Gerichtes erforderlichen Maßnahmen treffen.”. Supports Grundgesetz Art. 115l(1), (2): “(1) Der Bundestag kann jederzeit mit Zustimmung des Bundesrates Gesetze des Gemeinsamen Ausschusses aufheben. [...] (2) Der Bundestag kann mit Zustimmung des Bundesrates jederzeit durch einen vom Bundespräsidenten zu verkündenden Beschluß den Verteidigungsfall für beendet erklären. Der Bundesrat kann verlangen, daß der Bundestag hierüber beschließt. Der Verteidigungsfall ist unverzüglich für beendet zu erklären, wenn die Voraussetzungen für seine Feststellung nicht mehr gegeben sind.”. Supports Grundgesetz Art. 101: “(1) Ausnahmegerichte sind unzulässig. Niemand darf seinem gesetzlichen Richter entzogen werden. (2) Gerichte für besondere Sachgebiete können nur durch Gesetz errichtet werden.”. Supports Grundgesetz Art. 19(2) and Art. 79(3): “In keinem Falle darf ein Grundrecht in seinem Wesensgehalt angetastet werden. [Art. 19(2)] — Eine Änderung dieses Grundgesetzes, durch welche die Gliederung des Bundes in Länder, die grundsätzliche Mitwirkung der Länder bei der Gesetzgebung oder die in den Artikeln 1 und 20 niedergelegten Grundsätze berührt werden, ist unzulässig. [Art. 79(3)]”. Supports Grundgesetz Art. 115c(1), (3): “(1) Der Bund hat für den Verteidigungsfall das Recht der konkurrierenden Gesetzgebung auch auf den Sachgebieten, die zur Gesetzgebungszuständigkeit der Länder gehören. Diese Gesetze bedürfen der Zustimmung des Bundesrates. [...] (3) Soweit es zur Abwehr eines gegenwärtigen oder unmittelbar drohenden Angriffs erforderlich ist, kann für den Verteidigungsfall durch Bundesgesetz mit Zustimmung des Bundesrates die Verwaltung und das Finanzwesen des Bundes und der Länder abweichend von den Abschnitten VIII, VIIIa und X geregelt werden, wobei die Lebensfähigkeit der Länder, Gemeinden und Gemeindeverbände, insbesondere auch in finanzieller Hinsicht, zu wahren ist.”. These provisions support the STRUCTURE of German emergency law and nothing about its application. They record no instance of any regime being invoked, state no measure taken under one, and support no claim about any Land's own disaster-protection law or about any other country.WAVE 21 ADDITION. Read again from the same official English translation page and checked article by article against the authoritative German original at gesetze-im-internet.de/gg. Supports the LIMITATION architecture: Art. 19(1)-(2), “(1) Soweit nach diesem Grundgesetz ein Grundrecht durch Gesetz oder auf Grund eines Gesetzes eingeschränkt werden kann, muß das Gesetz allgemein und nicht nur für den Einzelfall gelten. Außerdem muß das Gesetz das Grundrecht unter Angabe des Artikels nennen. (2) In keinem Falle darf ein Grundrecht in seinem Wesensgehalt angetastet werden.”, and Art. 19(3)-(4) (basic rights apply to domestic legal persons so far as their nature permits; recourse to the courts where rights are violated by public authority, with the second sentence of Art. 10(2) expressly unaffected). Supports the RIGHTS-HOLDER finding, verified in the German text rather than the translation because the finding is about a word: Art. 8(1) “Alle Deutschen haben das Recht, sich ohne Anmeldung oder Erlaubnis friedlich und ohne Waffen zu versammeln”; Art. 9(1) “Alle Deutschen haben das Recht, Vereine und Gesellschaften zu bilden”; Art. 11(1) “Alle Deutschen genießen Freizügigkeit im ganzen Bundesgebiet”; Art. 12(1) “Alle Deutschen haben das Recht, Beruf, Arbeitsplatz und Ausbildungsstätte frei zu wählen” — against Art. 2(1) “Jeder hat das Recht auf die freie Entfaltung seiner Persönlichkeit”, Art. 3(1) “Alle Menschen sind vor dem Gesetz gleich”, and the two provisions that name no holder at all: Art. 10(1) “Das Briefgeheimnis sowie das Post- und Fernmeldegeheimnis sind unverletzlich” and Art. 13(1) “Die Wohnung ist unverletzlich”. Supports Art. 1(3), that the basic rights bind the legislature, the executive and the judiciary as directly applicable law. Supports Art. 2(2), that everyone has the right to life and physical integrity, that freedom of the person is inviolable, and that these rights may be interfered with only pursuant to a law. Supports the HOME provision in full: Art. 13(2) “Durchsuchungen dürfen nur durch den Richter, bei Gefahr im Verzuge auch durch die in den Gesetzen vorgesehenen anderen Organe angeordnet und nur in der dort vorgeschriebenen Form durchgeführt werden”; Art. 13(3), acoustic surveillance of a home on judicial order where particular facts justify suspicion of an especially serious crime specifically defined by law and alternative methods would be disproportionately difficult or unproductive, for a limited time, ordered by a panel of three judges (a single judge where time is of the essence); Art. 13(4), technical surveillance to avert acute dangers only on judicial order, with a subsequent judicial decision without delay where time was of the essence; Art. 13(5); Art. 13(6), annual reporting to the Bundestag and parliamentary oversight by an elected panel, with comparable oversight in the Länder; and Art. 13(7). Supports the COMMUNICATIONS provision: Art. 10(2), that restrictions may be ordered only pursuant to a law and that where the restriction serves to protect the free democratic basic order or the existence or security of the Federation or of a Land, the law may provide that the person affected shall not be informed and that recourse to the courts shall be replaced by review by agencies and auxiliary agencies appointed by the legislature. Supports Art. 103(1) (“Vor Gericht hat jedermann Anspruch auf rechtliches Gehör”) and Art. 104(1)-(4), including Art. 104(2) “Die Polizei darf aus eigener Machtvollkommenheit niemanden länger als bis zum Ende des Tages nach dem Ergreifen in eigenem Gewahrsam halten” and Art. 104(3), that a person provisionally detained on suspicion of an offence is brought before a judge no later than the day following arrest, who informs, examines, and either issues a written reasoned arrest warrant or orders release. VERIFIED NEGATIVE, and it is stated as a fact about the text and not about German law: the Grundgesetz contains no privilege against self-incrimination and no right to silence. An exhaustive search of the authoritative German text for “Selbstbelastung”, “schweigen”, “Aussage zu verweigern” and “Geständnis” returns zero occurrences, as does a search of the English translation for “incriminat”, “silent”, “silence”, “confession” and “witness against”. This record therefore does NOT support any claim that the principle is absent from German law — it supports only that it is absent from this constitutional text. The German text remains authoritative and the translation may lag later amendments.

The Court of Cassation's own official site, read directly. Supports the institution's name (Hof van Cassatie / Cour de cassation), that "there is one Court of Cassation for the whole Belgian territory" (giving effect to Constitution Art. 147), that it "is not a third degree jurisdiction" and "does not judge the dispute for a third time", and that it "analyses the legality of the rulings and does not know of the facts of the case". Resolves the translation point: the official English rendering of Art. 147 says "Supreme Court", but the institution is the Court of Cassation, which reviews legality, not facts.
