Appeal Procedures in Finnish Criminal Cases with Case Law
In Finland, appeal procedures are governed primarily by the Criminal Procedure Act (Rikoslaki 39/1889). Appeals ensure fair trial, correction of errors, and uniform application of the law. Finnish criminal appeals are hierarchical, moving from District Courts → Courts of Appeal → Supreme Court (KKO).
1. General Structure of Appeals
Appeal to the Court of Appeal (Hovioikeus)
Convicted persons, prosecutors, and sometimes victims can appeal.
Appeals can be on facts, evidence, or legal interpretation.
The Court of Appeal can reassess evidence and change verdict or sentence.
Appeal to the Supreme Court (KKO)
Only cases with significant legal questions or precedent value can go to the Supreme Court.
Supreme Court mostly reviews points of law, not the factual assessment.
Time Limits:
Appeal to Court of Appeal: within 30 days of the District Court decision.
Appeal to Supreme Court: requires a leave to appeal, typically filed within 30 days of Court of Appeal decision.
