Acceleration principle

The acceleration principle is a core guarantee in Swiss criminal procedure. Authorities must investigate, decide, and review cases within a reasonable time and avoid inactivity or unnecessary procedural steps. The duty is particularly strict when the accused is detained, because prolonged uncertainty or detention burdens fundamental rights. Breaches may lead to release from detention, mitigation of sentence, findings of delay, or procedural consequences, depending on severity. The principle protects the accused, victims, and public confidence in effective justice.
