Appellate Procedure in South Korea

Introduction

South Korea maintains a three-tier appellate system for civil, criminal, and administrative cases: District Court → High Court → Supreme Court. Each level serves a distinct function, with the scope of review narrowing at each successive tier. The system ensures thorough review while respecting the finality of lower court fact-finding.

First Instance Courts

Cases originate in:

• District Courts: General jurisdiction civil and criminal cases
• Family Court: Family law matters
• Administrative Court: Administrative litigation
• Patent Court: Patent and intellectual property cases
• Bankruptcy Court: Insolvency proceedings
• Branch Courts: Small claims and minor cases within district court territories

Intermediate Appeal — High Court

Scope of Review

The High Court conducts a de novo review (전면적 심리) of both fact and law. Unlike common law appellate courts, the High Court may:

• Re-evaluate evidence presented at trial
• Consider new evidence not presented below
• Make independent factual findings

Procedure

• Notice of appeal: Filed within two weeks of judgment (civil) or three weeks (criminal)
• Appeal brief: Required within 30 days; failure may result in dismissal
• Oral argument: The High Court holds hearings
• Decision: Affirm, reverse, or remand to the lower court

Grounds for Appeal

Civil appeals may challenge errors of fact or law. Criminal appeals may also challenge:

• Jurisdictional defects
• Procedural violations
• Improper application of the statute of limitations

Final Appeal — Supreme Court

Scope of Review

The Supreme Court of Korea reviews only questions of law (법률심). The Court does not review factual findings. Grounds for Supreme Court review include:

• Error in interpretation of the Constitution or law
• Violation of Supreme Court precedent
• Procedural defect affecting the judgment

Procedure

• Petition for final appeal (상고장) : Filed within two weeks of High Court judgment
• Leave to appeal: Since 2015, the Supreme Court may deny leave where no significant legal issue is presented
• En banc review: The full bench (14 justices) hears cases involving:
  • Constitutional interpretation
  • Overruling of Supreme Court precedent
  • Significant legal controversy

Disposition

The Supreme Court may:

• Affirm the High Court judgment
• Reverse and enter judgment (where facts are undisputed)
• Reverse and remand to the High Court for further proceedings

Criminal Appeals

Special Rules

• Prohibition of reformatio in peius: The appellate court may not impose a harsher sentence than the lower court if only the defendant appeals
• Mandatory defense counsel: In criminal appeals, indigent defendants are entitled to court-appointed counsel
• Speedy appeal: Criminal appeals are prioritized

Administrative Appeals

Exhaustion Requirement

Before filing an administrative action, the claimant must generally exhaust administrative remedies (Administrative Appeals Commission). Appeals from the Administrative Court go to the High Court and Supreme Court.

Constitutional Appeals

The Constitutional Court may review lower court decisions through:

• Statutory referral: When a court deems a statute unconstitutional
• Constitutional complaint: After exhaustion of ordinary remedies

Conclusion

South Korea’s three-tier appellate system provides thorough review at the intermediate level (fact and law) while concentrating the Supreme Court’s resources on legal questions and precedent-setting decisions. This structure balances litigant access to justice with efficient use of judicial resources and finality of judgments.
