Mistake Of Law And Mistake Of Fact In Finland
1. Case: KKO 2005:45 – Mistake of Fact in Assault Case
Incident: The defendant hit a person whom he believed was attacking him, but in reality, the person was not a threat.
Legal Principle: Mistake of fact (faktavirhe) occurs when a person is mistaken about factual circumstances relevant to the act.
Court Reasoning: The Supreme Court of Finland held that because the defendant’s perception of imminent danger was reasonable, he lacked the mens rea for assault. The mistake of fact negated criminal intent.
Outcome: Defendant acquitted.
Significance: Mistake of fact can absolve criminal liability if it negates intent or makes the act non-criminal.
2. Case: KKO 2010:62 – Mistake of Law Regarding Traffic Regulations
Incident: A driver claimed he did not know a particular road section was restricted to certain vehicles.
Legal Principle: Mistake of law (lakivirhe) occurs when a person is unaware of the law or misinterprets it. Generally, Finnish law holds that ignorance of the law is not an excuse (nullum crimen sine lege).
Court Reasoning: The Supreme Court emphasized that everyone is presumed to know the law. Unawareness or misunderstanding of traffic rules does not exempt the driver from liability.
Outcome: Convicted; fine imposed.
Significance: Confirms the principle that mistake of law is rarely a defense in Finland.
3. Case: KKO 2014:12 – Mistake of Fact in Theft Case
Incident: Defendant took property he believed was abandoned, but it actually belonged to someone else.
Legal Principle: Mistake of fact regarding ownership can negate intent (tarkoitustarkkaava virhe) in theft cases.
Court Reasoning: Finnish courts examined whether the defendant reasonably believed the property was ownerless. Because the belief was sincere and reasonable, the act lacked criminal intent.
Outcome: Acquitted.
Significance: Shows that honest factual mistakes about property ownership can prevent theft liability.
4. Case: KKO 2011:87 – Mistake of Law in Tax Evasion
Incident: A businessman argued that he misunderstood tax filing obligations and did not know he was required to declare certain income.
Legal Principle: Mistake of law is generally not a defense, except in cases where the law was ambiguous or incorrectly communicated by authorities.
Court Reasoning: Court acknowledged that while the law was complex, ignorance alone does not exempt liability. Only if the defendant relied in good faith on official guidance that turned out to be incorrect could liability be mitigated.
Outcome: Convicted; penalty reduced slightly due to partial reliance on official guidance.
Significance: Clarifies the narrow scope where mistake of law may influence sentencing, but not absolve criminal responsibility.
5. Case: KKO 2017:44 – Mistake of Fact in Self-Defense Claim
Incident: Defendant injured a person, believing them to be threatening with a knife; in reality, the person was unarmed.
Legal Principle: Mistake of fact can justify use of force if the belief of threat was reasonable.
Court Reasoning: Supreme Court examined whether the defendant’s perception of danger was reasonable under the circumstances. Since it was, the act was justifiable self-defense under Finnish Penal Code.
Outcome: Acquitted.
Significance: Reinforces that reasonable factual mistakes regarding threat can provide full legal justification.
6. Case: KKO 2009:52 – Mistake of Law Regarding Alcohol Licensing
Incident: Restaurant owner sold alcohol believing a special permit covered a particular date; it did not.
Legal Principle: Mistake of law generally does not excuse violation of licensing law.
Court Reasoning: Court noted the owner should have confirmed legal requirements. Even a sincere misunderstanding of regulations cannot prevent liability.
Outcome: Convicted; minor fine imposed.
Significance: Mistake of law is rarely a full defense but can sometimes reduce penalties if the misunderstanding was reasonable and good faith.
