On March 24, 2025, South Korea’s Constitutional Court overturned the impeachment of Prime Minister Han Duck-soo, reinstating him as acting president.

The court ruled in a 5-1 decision, with two justices declaring the impeachment motion invalid from the start. This ruling temporarily stabilizes the government after months of political turmoil.
Yoon Suk Yeol’s Controversial Martial Law and Impeachment
President Yoon Suk Yeol was impeached by the National Assembly on December 14, 2024, after declaring martial law on December 3.

His decree sent armed soldiers to the National Assembly, but lawmakers managed to convene and overturn it within six hours. Yoon’s impeachment led to Han Duck-soo taking over as acting president. However, Han was also impeached on December 27, accused of aiding Yoon’s actions and obstructing judicial appointments.
Court’s Reasoning for Overturning Han’s Impeachment
The Constitutional Court ruled that Han’s impeachment lacked legal grounds. Two justices further argued that the impeachment motion did not meet the required two-thirds majority in parliament.
Han denied any role in Yoon’s martial law decision, claiming he was informed only hours before it was enacted. His reinstatement has given hope to Yoon’s supporters but has also fueled political tensions.
What’s Next for Yoon Suk Yeol?
The court has yet to decide on Yoon’s impeachment. If upheld, a new presidential election must take place within 60 days. If overturned, Yoon will regain his presidential powers.
The court’s delay in ruling on Yoon’s case despite concluding hearings in February has raised speculation about internal divisions among the justices.
Some believe they are trying to reach a unanimous verdict to avoid worsening national divisions, similar to the impeachment of former President Park Geun-hye in 2017.
Political Reactions and Public Response
The opposition Democratic Party criticized the court’s handling of Han’s case, arguing that he failed to fulfill his constitutional duty by not appointing judges.
Party leader Lee Jae-myung called for a swift verdict on Yoon to prevent further instability.
On the other hand, Yoon’s ruling People Power Party argued that Han’s reinstatement proves that Yoon’s impeachment was politically motivated.

Yoon’s office called the impeachment efforts “reckless” and accused the opposition of misusing the process.
Public protests have continued for over three months, with rival groups either demanding Yoon’s removal or his reinstatement.
The delay in the court’s ruling has deepened public distrust in institutions and increased political uncertainty.
Possible Outcomes and Future Implications
If Yoon is reinstated, it could further polarize the country, as his supporters may see the court’s delay as a sign favoring his return.
However, if Yoon is removed, a presidential election will be required, potentially easing some tensions but also creating further political instability.
The Constitutional Court is expected to announce its verdict on Yoon’s case by June. This decision will determine whether South Korea moves toward stability or faces deeper political and social divisions.
