Swedish lay judges and political influence
Sweden does not use a peer jury in ordinary criminal trials. It uses politically nominated lay judges, or nämndemän, who deliberate with the professional judge and have an equal vote on guilt and sentence. The professional judge chairs the hearing and writes the judgment, but the lay majority can determine the outcome.
Political parties nominate candidates, and municipal or regional assemblies elect them for four-year terms. The design does not mean that lay judges act as party delegates. It does mean that access to the fact-finding body is institutionally routed through political organizations rather than random civic selection.
Politics in the courtroom provides causal evidence that this design can affect verdicts. Using random assignment at Gothenburg District Court, the researchers found substantial party-linked changes for defendants with Arabic-sounding names and cases with female victims, as well as peer effects on centrist lay judges.
The 2026 Riksrevision audit of Swedish lay judges was opened because of indications involving composition, suitability, training, bias, removal, and retrials. Its final report is due in October 2026.
The open questions are whether current selection and training reduce those effects, whether party-linked differences persist across courts and offence types, and whether written reasons reveal disagreement well enough for meaningful appellate review.
