Lay judge
A person without professional legal training who sits on the bench together with professional judges and takes part in the decision as a member of the court.
Also called: Schöffe, Schöffin, saiban-in, Laienrichter.
Why the concept exists
The same instinct that produces juries — that professional judges should not decide alone — arranged the other way. Instead of a separate body answering separate questions, the lay members join the bench, hear what the judges hear, and vote with them. Austria treats this as part of the democratic basic principle of its constitution: lay adjudication brings about participation of the people in the administration of justice.
Where it operates
Because lay judges sit with the professionals, their influence is a matter of arithmetic as much as of office: the ratio on the bench is fixed by law, and in the mixed systems researched here the lay members outnumber the professionals. What they may decide is set by law too, and it is often more than a juror decides — fact, law and sentence together with the judges rather than the question of guilt alone.
Worth knowing
A lay judge is not a juror sitting somewhere else in the room. The seat is on the bench, and in some systems it carries the judge’s office and vote for as long as the hearing lasts.
How far it travels
The office exists under different names and with materially different powers. Germany seats Schöffen on the Schöffengericht under the Courts Constitution Act; Japan’s saiban-in sit with professional judges and take part in sentencing; Austria seats Schöffen with one professional judge where the offence carries more than five years. Lay judges are selected differently too — in Austria at random from the electoral register. None of this generalises to systems not researched here.

Worked examples
Systems this platform has researched. Each example shows how one country actually arranges this — including where it departs from the general pattern.
- Austria
- In a Schöffengericht a professional judge decides on the verdict together with two Schöffen, and the Landesgericht sits in that formation where the offence carries more than five years’ imprisonment. Lay judges are drawn at random from the electoral register.
- Germany
- The Courts Constitution Act seats Schöffen on the Schöffengericht, where they sit with the professional judge as members of the court rather than as a separate body.

SCOPE: Austria, read directly on the justice ministry’s own explanatory page. Supports, verbatim: that the constitution provides for lay participation in Artikel 91 — "Dies sieht die österreichische Bundesverfassung (Bundes-Verfassungsgesetz) in Artikel 91 vor"; that lay adjudication is part of the democratic basic principle — "Laiengerichtsbarkeit ist daher ein Teil des demokratischen Grundprinzips der österreichischen Bundesverfassung und bewirkt eine Teilnahme der Rechtsprechung durch das Volk"; that a Geschworenengericht is composed of three professional judges (Schwurgerichtshof) and eight Geschworene (Geschworenenbank) — "Ein Geschworenengericht setzt sich aus drei Berufsrichter:innen („Schwurgerichtshof“) sowie acht Geschworenen („Geschworenenbank“) zusammen"; that in a Schöffengericht a professional judge decides on the verdict together with two Schöffen; that the Landesgericht sits as a Schöffengericht where the offence carries more than five years; that Geschworenengerichte decide particularly serious offences (life imprisonment, or a lower limit above five years and an upper limit above ten, e.g. murder); and that the Geschworenen decide guilt ALONE while the sentence is fixed together with the professional judges — "Die Geschworenen entscheiden allein über die Schuld des:der Angeklagten, über das Strafausmaß jedoch gemeinsam mit den Berufsrichter:innen". DOES NOT SUPPORT: the text of Art. 91 itself, which RIS did not serve; any claim that Geschworenengerichte try POLITICAL offences, which this page does not mention; and nothing outside Austria.

SCOPE: Austria, selection of lay judges only. Supports, verbatim: "Laienrichter werden nach dem Zufallsprinzip aus der Wählerevidenz ausgewählt" — lay judges are chosen at random from the electoral register. DOES NOT SUPPORT: court composition or decision-making powers. A search result attributed both to this page; reading the page showed it carries neither, which is why the composition facts are cited to at-justiz-rechtsprechungsgrundsaetze instead.

SCOPE: Germany, the three sections read directly at their own pages on the official consolidated text; the record’s url is § 30, the section carrying the load-bearing provision. Supports § 28: "Für die Verhandlung und Entscheidung der zur Zuständigkeit der Amtsgerichte gehörenden Strafsachen werden, soweit nicht der Strafrichter entscheidet, bei den Amtsgerichten Schöffengerichte gebildet." Supports § 29(1): "Das Schöffengericht besteht aus dem Richter beim Amtsgericht als Vorsitzenden und zwei Schöffen.", and that a second professional judge may be added on the prosecution’s application when the main proceedings are opened. Supports § 30(1), the provision that matters most: Schöffen exercise during the Hauptverhandlung "das Richteramt in vollem Umfang und mit gleichem Stimmrecht wie die Richter". Supports § 30(2), the limit on that: decisions required OUTSIDE the main hearing are taken by the professional judge alone. Establishes nothing about how Schöffen are selected, nothing about courts above the Amtsgericht, and nothing about any other country.
