Age Thresholds For Criminal Responsibility
I. Overview of Age Thresholds for Criminal Responsibility in Finland
In Finland, criminal responsibility is defined under the Finnish Criminal Code (39/1889, as amended). Age is a critical factor in determining whether a person can be held criminally liable.
Key Age Thresholds:
Under 15 years old
Children under 15 cannot be held criminally responsible (Chapter 5, Section 1).
Measures: Reprimands, educational interventions, social welfare involvement.
15–17 years old (Juvenile offenders)
Can be held responsible for crimes but courts emphasize rehabilitation over punishment.
Sentences may include probation, juvenile detention, or community service rather than standard imprisonment.
18 years and older (Adults)
Full criminal responsibility applies.
Standard adult sentencing and penalties are imposed.
Special Cases
Courts may adjust sentencing for 18–20-year-olds if maturity is considered limited.

III. Key Principles from Case Law
Absolute protection for under-15s – no criminal liability, focus on social and educational measures.
Rehabilitation for 15–17-year-olds – probation, counseling, and juvenile detention prioritized over standard imprisonment.
Graduated responsibility for 18–20-year-olds – can be fully accountable, but courts may consider maturity.
Serious crimes by juveniles – may justify custodial sentences, but tailored to developmental needs.
Consistency for all residents – foreign minors are subject to Finnish juvenile law.
IV. Conclusion
Finland’s age thresholds for criminal responsibility reflect a human-rights-oriented and rehabilitative approach, balancing societal protection with offender development. Case law shows courts consistently:
Protect children under 15
Emphasize rehabilitation for 15–17-year-olds
Exercise some discretion for young adults (18–20)
Apply proportionality even for serious offenses
