Sweden Introduces Indeterminate Sentence to Enhance Public Safety

On April 15, 2026, Sweden implemented a new indeterminate custodial sentence called 'security detention' to strengthen societal protection against individuals with a high risk of reoffending in serious crimes. This measure targets offenders who have committed severe crimes and are deemed likely to commit similar offenses again but do not qualify for life imprisonment or psychiatric care. Under the new system, courts will set a minimum period equivalent to the prison term that would have been imposed and a framework period extending four to six years beyond the minimum. The framework period can be extended by up to three years at a time if necessary to prevent reoffending. There is no conditional release from security detention; instead, courts may decide on conditional release under supervision, which can be revoked if the individual misbehaves or commits new crimes. This legislation is part of the government's broader shift in criminal policy, focusing on victim rights and public safety.
