The Supreme Court is set to issue its ruling this week on the case of former President Yoon Suk-yeol obstructing the Corruption Investigation Office for High-ranking Officials (CIO) from executing an arrest warrant. As controversy over the legality of the CIO's investigative authority was persistently raised during the lower court proceedings, this Supreme Court ruling is expected to set a benchmark for similar cases going forward.
According to legal circles Sunday, the Supreme Court's Third Division (presiding Justice Lee Sook-yeon) will hold the sentencing hearing for the final appeal on Tuesday for Yoon, who was indicted on charges including obstruction of special official duties. This marks the first Supreme Court judgment among a total of eight criminal trials Yoon faces, including charges of masterminding an insurrection.
Yoon was indicted on charges including obstructing the execution of the arrest warrant through the Presidential Security Service and others during the CIO's warrant execution following the Dec. 3 emergency martial law. Yoon was sentenced to five years in prison in the first trial and seven years in the second trial. The first and second trial courts ruled most of the charges guilty, including infringing on cabinet members' right to deliberate at the State Council, drafting and destroying a martial law declaration after the fact, and blocking the CIO's execution of the arrest warrant.
One of the biggest points of contention during the trial was the legality of the CIO's investigation. The controversy over the CIO's direct authority to investigate insurrection charges continued from the early stages of the case and was also raised as an indirect issue during the decision to cancel Yoon's detention in March last year. Yoon's side argued for dismissal of the charges in the insurrection leadership case and others, citing that the CIO Act does not specify authority to investigate insurrection charges. However, the first and second trial courts recognized the CIO's investigative authority, stating that "in the course of investigating abuse of authority and obstruction of the exercise of rights by high-ranking officials, related crimes such as insurrection charges can also be investigated." Accordingly, the CIO's execution of the arrest warrant was recognized as a legitimate performance of official duties, and Yoon's act of obstructing it was found to constitute the crime of obstruction of special official duties.
Legal circles analyze that this Supreme Court judgment could effectively put an end to the controversy over the CIO's investigative authority. A lawyer who is a former senior judge said, "If the Supreme Court dismisses the appeal, the legal principle that the CIO can investigate insurrection charges as a related crime in the course of an abuse-of-authority investigation will effectively be established," adding, "It will also carry the significance of presenting a standard for judging similar cases in the future."
