Concern of Evidence Destruction
Overview
Concern of evidence destruction is one of the grounds for detention stipulated in Article 70, Paragraph 1 of the Criminal Procedure Act, referring to cases where there is a risk that a suspect or defendant may destroy, conceal, forge, or alter evidence related to criminal charges. Along with the risk of flight, it serves as a key criterion for courts to issue or maintain arrest warrants, acting as an institutional mechanism to ensure the securing of evidence by investigative agencies and the conduct of a fair trial. Concern of evidence destruction must be recognized based on objective and reasonable circumstances, not mere speculation, and requires strict scrutiny as it involves limiting the constitutional principle of presumption of innocence and personal liberty.

Legal Basis and Requirements
Article 70 of the Criminal Procedure Act specifies as a ground for detention "when there is a concern that the defendant may destroy evidence." For concern of evidence destruction to be recognized, the following requirements must be met:
- Specific Circumstances: There must be concrete actions by the suspect to destroy evidence already taken, or circumstances suggesting collusion with related parties to eliminate evidence.
- Importance of Evidence: The evidence at risk of destruction must be essential for proving core facts of the case.
- Principle of Proportionality: There must be a balance between the necessity of detention and the restriction of the suspect's fundamental rights; if evidence destruction can be prevented by means other than detention, detention should be avoided.
Criteria for Judgment
Courts and investigative agencies comprehensively consider the following factors when assessing concern of evidence destruction:
- Severity of the Crime: More serious crimes are considered more likely to involve attempts at evidence destruction.
- Type of Evidence: Both physical evidence (documents, electronic records, DNA, etc.) and human evidence (witnesses, accomplices, etc.) are relevant.
- Suspect's Attitude: Uncooperative behavior during investigation or retraction of statements raises suspicion of evidence destruction attempts.
- Criminal Record and Similar Offenses: A history of evidence destruction or repeated similar crimes increases concern.
- Social Relationships: The possibility of the suspect using power or financial resources to manipulate evidence is also considered.
Procedure and Specific Examples
Concern of evidence destruction is primarily used as a reason presented by prosecutors to courts during the request for an arrest warrant. For example, cases where a suspect destroys a mobile phone under investigation, burns related documents, or is found to have contacted accomplices to conceal evidence are typical. It also includes instances where a suspect obstructs investigative agencies' search and seizure or intimidates witnesses to change their statements. Courts issue arrest warrants when such circumstances are supported by objective evidence.
Alternatives to Detention
Even if there is concern of evidence destruction, detention is not automatic. Courts may impose bail conditions (e.g., residence restrictions, attendance obligations, electronic monitoring, orders prohibiting evidence destruction) as alternatives to detention. In particular, if the suspect has strong social ties and there is confidence that no evidence destruction will occur, non-custodial investigation is possible. This relates to the bail system under Article 97 of the Criminal Procedure Act.
Recent Trends
As of 2024-2025, legal discussions surrounding concern of evidence destruction are becoming more complex with the prevalence of digital evidence. First, advances in digital forensics technology have made attempts at evidence destruction more sophisticated, leading investigative agencies to strengthen legal grounds for responding to cloud data deletion, encryption, and remote wiping. Second, in a 2024 ruling, the Supreme Court reaffirmed that recognizing concern of evidence destruction requires "specific and clear danger," not mere speculation, taking a cautious stance against abuse of detention. Third, following the adjustment of investigative powers between the prosecution and police, the number of arrest warrant requests citing concern of evidence destruction has somewhat decreased, but they are still granted at a high rate in serious crimes (e.g., drugs, organized crime, economic crimes). Fourth, in 2025, the introduction of AI-based risk assessment tools for evaluating concern of evidence destruction is being discussed, but a cautious approach is required due to concerns over human rights violations. Finally, socially, cases involving high-ranking public officials or business figures where concern of evidence destruction is linked to political and economic influence are increasingly controversial.
