A South Korean court has sentenced former Prime Minister Han Duck-soo to 23 years in prison for his involvement in the insurrection linked to ex-President Yoon Suk-yeol's attempt to impose martial law in December 2024. The court ruling characterized the martial law declaration as an act of insurrection, marking the first time such an occurrence has been formally identified as insurrection by judicial standards. Han's convictions included charges of perjury and being instrumental in the insurrection, as he allegedly helped create a facade of legality for the emergency cabinet meeting that facilitated the martial law declaration, according to SCMP and Channel News Asia.

According to the Seoul Central District Court judge, Han had a constitutional obligation to uphold democratic principles, yet he failed to fulfill this duty and enabled the insurrection efforts. The court emphasized that his actions posed a severe threat to the nation's democratic framework. The sentencing comes after an unusual legal precedent where the judge opted for a sentence longer than the prosecution's recommendation, indicating significant disapproval of Han's conduct during this tumultuous period, as reported by AA and SCMP.

The implications of Han's sentencing extend to former President Yoon, who awaits his own verdict following serious charges including obstructing justice and being labeled as the insurrection's ringleader. As analysts point out, the case against Han effectively dismantles the legal narrative that Yoon's martial law decree was a legitimate exercise of presidential authority. This judicial definition will likely shape the outcome of Yoon's trial scheduled for February 19, as both cases are handled by the same court, according to SCMP, AA, and Channel News Asia.

The court's ruling also ignited discussions regarding the future of South Korean governance and the implications of a court that shows willingness to impose severe penalties for undermining democracy. The judge articulated that actions akin to the December 3 martial law attempt could introduce significant risks to democratic institutions and civil order, a sentiment echoed by legal analysts. The case represents a pivotal moment in South Korea's political landscape, reflecting ongoing repercussions for those involved, as indicated by SCMP and AA.
