Criminal Procedure In Finland

Criminal Procedure in Finland with Case Law

Criminal procedure in Finland is governed mainly by the Criminal Procedure Act (Rikoslaki 39/1889) and related statutes. The system emphasizes fair trial, legality, and proportionality, with an inquisitorial-adversarial hybrid model.

1. Investigation Stage

Authority: Police conduct investigations under supervision of the prosecutor.

Objective: Gather evidence, question suspects, secure witnesses, and determine whether charges are justified.

Key Principle: Suspects have the right to counsel; coercive measures require justification (e.g., remand in custody).

Facts: A man suspected of murdering his partner. Police collected forensic evidence, digital communications, and witness statements.

Process: The suspect was detained for 10 days, during which his communications were monitored.

Outcome: Prosecutor filed charges based on strong forensic evidence. The suspect later admitted the crime.

Significance: This case illustrates police powers in serious crimes, procedural safeguards, and prosecutor’s role in advancing charges.

2. Pre-Trial Detention and Rights of the Suspect

Legal Basis: Pre-trial detention is allowed only if necessary to secure the investigation, prevent flight, or protect the public.

Rights: Suspects can request bail; the court reviews detention periodically.

Significance: Demonstrates Finnish courts balancing state interest and individual liberty in pre-trial detention.

3. Prosecution Decision

Principle: Finland follows prosecutorial discretion, but the principle of legality generally requires prosecution for offenses with sufficient evidence.

Diversion: For minor crimes or young offenders, prosecutors can issue warnings or conditional fines instead of formal charges.

Case 3: Conditional Prosecution (KKO 2015:41)

Facts: A 19-year-old committed petty theft for the first time. Prosecutor considered whether formal charges were necessary.

Process: Prosecutor offered a conditional fine and apology to the victim instead of court proceedings.

Outcome: The young adult paid the fine and avoided a criminal record.

Significance: Shows Finnish prosecutors’ use of discretion and diversion to reduce court load and avoid unnecessary criminalization.

4. Trial Proceedings

Court: Trials are conducted in District Courts (Käräjäoikeus).

Participants: Judge(s), prosecutor, defense counsel, witnesses, and parties.

Procedure: Evidence presented, witnesses examined, cross-examination occurs, and the court decides guilt and sentence.

Special Feature: Finland uses lay judges in some cases, especially serious crimes like assault or homicide.

Facts: A man assaulted a neighbor, causing serious injury. Case heard in district court with 1 professional judge and 2 lay judges.

Process: Witnesses, medical reports, and CCTV evidence were presented. Lay judges participated in questioning.

Outcome: Defendant found guilty of aggravated assault; sentenced to 18 months imprisonment.

Significance: Demonstrates role of lay judges and evidence-based proceedings in Finnish courts.

Fines (day-fines system)

Conditional sentences

Significance: Highlights Finnish day-fine system, linking punishment to offender’s financial capacity.

6. Appeals Process

Supreme Court: Only cases of significant legal precedent go to KKO (Supreme Court).

Case 6: Appeal on Evidence Admissibility (KKO 2019:73)

Facts: Defendant challenged use of mobile phone location data as evidence.

Court Analysis: Supreme Court ruled evidence admissible, emphasizing lawful police procedures and proportionality.

Significance: Reinforces Finnish courts’ focus on procedural safeguards in evidence collection.
