Modernisation Of Finnish Criminal Law In The 20Th Century
I. Background: Modernisation of Finnish Criminal Law
Historical Context
Finland’s criminal law underwent major reform in the 20th century, moving from a 19th-century Penal Code (inherited from Russian law and earlier Swedish laws) to a modern, codified, and human-rights-oriented system.
Major influences included:
European continental legal tradition
International human rights developments
Social reforms and welfare state principles
Key Legislative Milestones
Rikoslaki (Criminal Code 1889–1880s) – Early codification with strong punitive focus.
Rikoslaki 1889 Revision (post-independence) – Adaptation to Finnish sovereignty.
Modern Criminal Code 1889–1930s amendments – Focus on proportionality, classification of offences, and procedural protections.
Post-WWII Modernisation (1940s–1970s) – Incorporation of juvenile justice, probation, conditional imprisonment, and social rehabilitation.
Late 20th Century (1980s–1990s) – Harmonisation with EU standards and human rights law, modern definitions of violent crimes, sexual offences, and white-collar crime.
II. Key Modernisation Themes in Finnish Criminal Law
Proportionality and Individualisation of Sentences
Move away from harsh, uniform punishment to flexible sentencing based on circumstances.
Introduction of probation, conditional sentences, and community service.

Special treatment for under-18 offenders.
Focus on rehabilitation rather than punishment.
