Slack Investigation
Overview
A slack investigation refers to the act of investigative agencies (such as the police and prosecution) intentionally reducing, delaying, distorting, or covering up investigations into specific individuals or groups, particularly those in power, those with connections, or politicians, rather than conducting a strict investigation in accordance with the law and principles. This is a direct violation of the principle of equality and due process under the Criminal Procedure Act, and it is a major cause of significantly damaging the public's legal sentiment and leading to judicial distrust. A slack investigation is considered not a mere investigative mistake or error, but a deliberate and systematic distortion of law enforcement.

Concept and Types
Slack investigations generally manifest in the following types. First, delay in initiating an investigation, where, despite a complaint or accusation being filed, the investigation is not promptly initiated, allowing time to be wasted or evidence to be easily destroyed. Second, reduction of the investigation scope, where, despite multiple related charges, only some are investigated, or key suspects are intentionally excluded. Third, concealment or manipulation of evidence, where unfavorable evidence is omitted or ignored, and only favorable evidence is adopted. Fourth, weakening of punishment, where arrest warrants are avoided, or the case ends with a slap-on-the-wrist punishment such as summary indictment or suspension of indictment.
Causes
The structural causes of slack investigations are diverse. Collusion with power is the most representative. This occurs when investigative agencies like the prosecution and police collude with political power or economic power such as chaebols to provide preferential treatment. Internal cronyism within the organization is also an important cause, where investigations are distorted due to personal connections such as colleagues, seniors-juniors, or alumni. Organizational protectionism cannot be ignored either, where internal investigations are reduced to cover up the investigative agency's own corruption or wrongdoing. Additionally, excessive workload and fear of personnel disadvantages are factors that make investigators avoid active investigations.
Social Impact
Slack investigations have severe adverse effects on society as a whole. First, they shake the foundation of the rule of law. If the principle that all are equal before the law collapses, public trust in the law plummets. Second, the deterrent effect on crime weakens, encouraging similar crimes. If slack investigations become widespread, criminals perceive that they can avoid punishment. Third, the suffering of victims intensifies. Victims expect proper investigation and punishment but face double suffering when these expectations are frustrated. Fourth, social inequality deepens. The perception spreads that wealthy or powerful individuals can evade legal judgment.
Precedents and Cases
In South Korea, suspicions of slack investigations have arisen multiple times. Notable examples include cases where investigations into incidents involving politicians were reduced or covered up, and cases involving chaebol chairpersons where arrests were not made and trials were delayed for long periods. The Constitutional Court and the Supreme Court have emphasized the fairness of investigations and the principle of equality, issuing rulings that caution against arbitrary decisions by investigative agencies. For example, there is a precedent that a suspension of indictment against a specific individual can be subject to a constitutional complaint if it is significantly unreasonable.
Recent Trends
As of 2024-2025, the issue of slack investigations is emerging as an even more acute social issue. Following the debate over the complete removal of prosecution investigative powers, the reorganization of investigative authority between the prosecution and police is progressing, strengthening checks and balances between investigative agencies. In particular, with the full-fledged activities of the Corruption Investigation Office for High-ranking Officials (CIO), a check function against slack investigations by existing investigative agencies is partially operating. Additionally, monitoring by civic groups and the media has strengthened, leading to immediate public opinion surveys and National Assembly hearings when suspicions are raised. The development of digital forensics technology has also made it difficult to conceal or manipulate evidence, which is a positive change. However, cases of undermining political neutrality are still being reported, and continuous demands are being made to improve the personnel system of investigative agencies and enhance transparency.
