South Korea’s Judicial Overhaul: Expansion, Appeals and Concerns Over ‘Law Distortion’

South Korea’s judiciary underwent a significant transformation on March 12, 2026, with the implementation of a series of judicial reform laws. These changes, which include expanding the Supreme Court, introducing a new constitutional appeals channel, and criminalizing the “distortion” of law by judges and prosecutors, have sparked both support and controversy.

Expansion of the Supreme Court

A key component of the reform is a revision to the Court Organization Act, increasing the number of Supreme Court justices from 14 to 26 by 2030. This expansion will grant President Lee Jae Myung considerable influence over the court’s composition, with the expectation that he will appoint 22 of the 26 justices by the complete of his term in June 2030. The court will add four new justices annually from 2028 to 2030.

The government and the ruling Democratic Party (DP) argue that the expansion is necessary to address a growing caseload, with each justice currently handling an average of 3,478 cases per year. However, critics express concerns about potential court-packing and the concentration of power in the executive branch.

Introduction of Constitutional Appeals

The reforms also introduce a new constitutional appeals channel, allowing for the review of Supreme Court rulings by the Constitutional Court. This has raised concerns that the Constitutional Court could become a de facto “fourth instance” of appeal, potentially prolonging legal proceedings and increasing dissatisfaction with the judicial process.

Criminalization of ‘Law Distortion’

Perhaps the most controversial aspect of the reforms is the creation of a new offense – “distortion of law.” This law criminalizes actions by judges and prosecutors deemed to be a misapplication of the law during trials or investigations. The application criteria for this offense are considered ambiguous, leading to fears of misuse and potential repercussions for judicial officials.

Concerns Over Increased Complaints and Accusations

Experts warn that the “law distortion” provision may lead to a surge in complaints and accusations against judicial personnel. As of 2024, the number of complaints filed with the police was close to 700,000, with an additional 90,000 filed directly with the prosecution. The ease with which complaints can be filed, coupled with a lack of penalties for false accusations, contributes to this high volume. There is a concern that the new law will exacerbate this trend, potentially overwhelming investigative agencies and hindering their ability to function effectively.

Political Context

These judicial reforms were approved by President Lee Jae Myung despite calls for a veto. The Democratic Party initiated these bills in May of the previous year following the Supreme Court’s ruling against President Lee in an election law violation case. The speed with which the ruling party pushed these bills through the National Assembly has also drawn criticism, with concerns raised about a lack of sufficient social consensus.

Looking Ahead

The long-term impact of these judicial reforms remains to be seen. While proponents argue they are necessary to improve the efficiency and fairness of the legal system, critics fear they could undermine judicial independence and concentrate power in the executive branch. The coming years will be crucial in assessing whether these changes strengthen or weaken the foundations of South Korea’s legal system.
