Risk of Flight

Risk of Flight

Overview

The risk of flight is one of the grounds for detention prescribed under Article 70 of the Criminal Procedure Act. It refers to a state in which there is a substantial concern that a suspect or defendant will not appear in trial or investigative proceedings. The risk of flight serves as a core standard in deciding whether to issue a detention warrant, renew detention, or grant bail, and is an important factor in assessing the necessity of detention. The courts and prosecutors in the Republic of Korea evaluate the risk of flight by comprehensively considering objective circumstances and individual factors. In recent years, a stricter interpretation has been adopted in light of the presumption of innocence and the protection of human rights.

Legal Basis

Article 70 (Grounds for Detention) of the Republic of Korea Criminal Procedure Act provides that a court may issue a detention warrant for a suspect or defendant when: (1) the person has no fixed residence; (2) there is a concern that evidence will be destroyed; or (3) the person has fled or is likely to flee. In particular, Article 70(1)(iii) expressly states "when the person has fled or there is a concern that the person may flee," and paragraph (2) provides that, in determining the necessity of detention, the court shall consider the defendant's age, conduct, intelligence, environment, family relations, occupation, the seriousness of the crime, and whether there is circumstantial evidence. Article 71 further provides that the court may, when necessary in detaining a defendant, impose conditions such as restricting the defendant's residence or requiring the defendant to stay at a place designated by the court, and may revoke the detention ex officio where the risk of flight has been resolved.

Standards for Assessing the Risk of Flight

The specific standards for assessing the risk of flight are not enumerated in statutory law, but Supreme Court precedents and practice consider the following factors comprehensively.

1. Seriousness of the crime: The more serious the crime, the heavier the potential sentence and thus the greater the motive to flee. The risk of flight is more likely to be recognized in serious crimes punishable by death, life imprisonment, or long-term imprisonment of three years or more.

2. Escape history or attempts: Whether the person has a previous history of fleeing, attempted to flee during investigation or trial, gone into hiding, or attempted to escape abroad.

3. Stability of residence and employment: The risk of flight decreases where social ties are strong, such as having a fixed residence, a job, or family dependents. Conversely, unemployment, lack of a fixed residence, or a wandering lifestyle is more likely to be assessed as a high flight risk.

4. Stage of investigation or trial: The same standards apply during the trial stage as in the early investigative stage before indictment; in particular, the risk of flight may increase when the likelihood of a guilty verdict becomes higher.

5. Criminal record and recidivism: A prior history of similar crimes or recidivism may reflect a tendency to flee along with the risk of reoffending.

6. Relationship with victims and risk of retaliation: Threats against victims or accomplices, or the possibility of retaliation, may also be assessed in connection with the risk of flight.

The courts do not simply list these factors; they examine their interrelations and make a comprehensive judgment centered on social ties and whether there is a motive to flee. The Supreme Court has held that "to find a concern of flight, a substantial probability of flight must be recognized; mere possibility of flight is insufficient," maintaining that detention cannot be justified by abstract possibility alone.

Risk of Flight in Warrant Practice

When the prosecution applies for a detention warrant, the materials submitted to prove the risk of flight mainly include suspect interrogation reports, records of failure to comply with attendance summons, overseas departure history, and materials confirming the suspect's home and workplace. Even at the police investigation stage, if a suspect fails to respond to a summons or has no fixed residence, the police may make an emergency arrest and apply for a detention warrant on the ground of flight risk.

During the substantive warrant review (suspect examination), the judge in charge directly examines whether the suspect poses a flight risk and hears arguments from both the prosecution and the defense. At this stage, defense counsel may rebut the risk of flight by pointing to a fixed residence, continued employment, family dependents, no history of flight, and cooperation with the investigation. Under the principle that the burden of proving the necessity of detention lies with the prosecution, the warrant judge strictly examines both the risk of evidence destruction and the risk of flight.

Risk of Flight in Bail Review

The bail system is designed to guarantee the defendant's physical freedom while ensuring attendance at trial. Article 96 of the Criminal Procedure Act provides that, upon a request for bail, the court shall grant bail if it finds that the defendant has no risk of flight. However, the proviso to Article 96(1) and Article 97 allow the court to deny bail where there is a risk of flight, the crime is serious, there is a concern of evidence destruction, or there is a risk of harm to victims or witnesses.

Since the 2020s, courts have tended to relax the requirements for granting bail. They are actively using conditional bail, which requires the defendant to pay a certain deposit and imposes conditions such as residence restrictions, travel bans, electronic monitoring (ankle bracelets), and orders to appear in court. This shows that practice has shifted toward protecting human rights through conditional release rather than detention in cases where no concrete risk of flight is recognized. In particular, in 2023 the Supreme Court ordered that, when assessing the risk of flight in bail review, courts should more carefully evaluate the defendant's health condition, social ties, and degree of cooperation with the investigation.

Related Issues and Criticism

The concept of the risk of flight has been continuously debated in the legal community and academia because of its abstractness and the possibility of arbitrary application.

• Conflict with the presumption of innocence: Detention occurs before trial and may therefore conflict with the presumption of innocence. There is criticism that using the risk of flight as a ground for detention presupposes potential guilt.
• Economic inequality: Because social ties and employment stability are major factors in assessing the risk of flight, economically vulnerable groups may be assessed unfavorably, and a risk of flight may be too easily recognized.
• Burden of proving the risk of flight: The prosecution has the burden of proving the risk of flight, but objective evidence is often difficult to secure, leading to reliance on speculative judgment.
• Abuse of detention: Human rights organizations criticize that the risk of flight may be excessively invoked for investigative convenience, resulting in abuse of detention.

Recent Trends

From 2024 to 2025, the standards for assessing the risk of flight in detention warrant and bail review in South Korean courts have become stricter. According to the Court Administration Service and the Supreme Court's Judicial Yearbook, the nationwide district court detention warrant rejection rate in 2024 approached approximately 30 percent, the highest level ever recorded. This means that courts found the prosecution's stated grounds for flight risk insufficient in an increasing number of cases.

In particular, in cases that are not serious crimes, rulings recognizing a risk of flight merely because the person was unemployed or had temporary housing have declined. Meanwhile, conditional bail has increased significantly for defendants with recognized social ties. The Rules of Criminal Procedure, amended in 2024, newly required that specific facts concerning the risk of flight be stated during the pre-detention examination of the suspect, reflecting an effort to reduce detention based only on formal grounds.

In 2025, bail with protective supervision conditions, such as attachment of electronic monitoring devices, has been further expanded. In property crimes or fraud cases where the defendant has a low probability of fleeing, prompt bail decisions have become the trend. In addition, the Supreme Court has clarified the "burden of proof regarding the risk of flight," issuing successive rulings that deny detention grounds where the evidence submitted by the prosecution does not establish a probability of flight.

Furthermore, following recommendations from international human rights bodies and academia, South Korea has been discussing ways to activate alternatives to detention. A practical practice is taking root in which, for suspects with a fixed residence and occupation, attendance orders or payment of a deposit are considered first rather than detention.
