A South Korean court acquitted former President Yoon Suk Yeol of perjury charges in a first-instance ruling regarding a martial law declaration [1, 2].

The ruling marks a significant legal victory for the former leader, while his former staff member faces immediate imprisonment for fabricating official records. This divergence in sentencing highlights the court's distinction between the interpretation of constitutional procedures, and the intentional falsification of evidence.

Prosecutors had charged Yoon with perjury, alleging he gave false testimony regarding the necessity of a Cabinet meeting to declare emergency martial law [1, 2]. The court rejected these claims, stating it was difficult to conclude that the testimony differed from the actual memories of the events [1, 2].

"When declaring martial law, the requirement to go through a Cabinet meeting is stipulated in the Constitution, and I believe it is something everyone knows," Yoon said [1].

While Yoon was cleared, the court took a harsher stance toward Kang Ui-gu, the former chief of the presidential office's attachment office [1, 2]. Kang received a prison sentence and was detained after being found guilty of creating a cover for a post-dated proclamation [1, 2].

The legal proceedings stem from testimony provided by Yoon in 2023, with the first-instance verdict delivered in early 2024 [1, 2]. The court determined that while the administrative handling of the proclamation by Kang was criminal, the former president's statements regarding the legal process of martial law did not constitute perjury [1, 2].

Former President Yoon avoids conviction while former aide Kang Ui-gu receives prison sentence.

This ruling separates the political and constitutional arguments surrounding the martial law attempt from the administrative crimes of its executors. By acquitting Yoon but imprisoning Kang, the court suggests that while the former president's recollection of constitutional requirements was acceptable, the physical fabrication of official documents remains a clear criminal offense.
