Free evaluation of evidence in Sweden
Swedish procedure is generally described through free production and free evaluation of evidence. Parties may ordinarily offer relevant material, and the court assesses its evidentiary value rather than applying a broad exclusionary rule based on how it was obtained.
In NJA 2021 p. 286, the Supreme Court emphasized that exclusion is exceptional. That procedural rule does not make collection lawful. A recording may be admitted or considered while its creation still raises criminal, employment, privacy, or data-protection issues.
The distinction matters in Covert recording and evidence in Sweden: lawfulness of collection, admissibility, weight, and disclosure are separate questions. Evidence should therefore be preserved without editing, with provenance and context sufficient to test authenticity.
The freedom to assign weight also creates a methodological risk. Felaktigt dömda found courts relying on speculative trauma theories, unsourced general experience, and the supposedly self-experienced quality of a narrative. The report warned that free evaluation can become too free when the reasons do not expose a testable path from evidence to the proof threshold.
Rättssäkerhet in Swedish criminal cases develops that critique without arguing for automatic exclusion of disputed evidence.
