South Korea began enforcing a law Tuesday that allows steep punitive damages against news outlets and social media influencers for spreading false information. Journalist groups and civil liberties advocates have warned that the legislation could chill public discourse and invite censorship.

The law, which was backed by President Lee Jae Myung’s liberal Democratic Party and passed in December, allows courts to award damages up to five times the proven losses against news organizations and large social media channels, including YouTube creators, that circulate illegal, false, or manipulated information with the intent to cause harm or generate profit.

Individuals who distribute information more than twice after a court has confirmed it to be false or manipulated could face fines up to 1 billion South Korean won ($656,000) from the country’s media regulator. Internet companies operating large social media platforms with more than 1 million daily users are also required to implement measures such as content removal or account suspension when they receive reports of false or fabricated information.

Proponents of the law, including the Democratic Party, argue it is necessary to combat fake news and disinformation, which they contend pose a growing threat to democracy by fueling division and hate speech. The party unsuccessfully sought similar legislation under previous governments.

However, critics, including the Journalists Association of Korea and the Seoul Foreign Correspondents’ Club, have raised concerns about the law's vague wording and lack of adequate safeguards for the media. They argue that the mere prospect of facing massive damage claims or legal disputes could have an "unavoidable chilling effect," potentially discouraging critical reporting about government officials, politicians, and large businesses.

"Even if a law’s objective is legitimate, it could erode the foundations of democracy if it’s enforced in a way that discourages the media and ordinary citizens from freely criticizing and scrutinizing those in power," the Journalists Association of Korea stated.

The push for the law gained momentum following then-President Yoon Suk Yeol's brief imposition of martial law in 2024. Yoon, who was later impeached, removed from office, and convicted of rebellion, promoted unsubstantiated election fraud claims. Critics contend that Yoon’s campaign further polarized the country by injecting falsehoods into political disputes.

The Korea Media and Communications Commission has downplayed fears of state censorship, stating that private platform operators, not the government, will determine if content is false or manipulated. The commission also noted that the law exempts reporting conducted in the public interest from damages claims.

Despite these assurances, some experts, like Kim Hong-yeol, a professor at Seoul’s Duksung Women’s University, expressed concern that the law could encourage widespread self-censorship and discourage discussions on sensitive issues. Kim suggested that internet companies might adopt overly aggressive moderation policies to avoid liability, potentially leading to the removal of legitimate content.

While major South Korean internet companies like Naver and Kakao are reportedly updating their systems to comply with the new regulations, it remains unclear how major foreign platforms, such as Google’s YouTube, will adapt. Google did not immediately respond to a request for comment.

Following the law's passage in December, U.S. Under Secretary of State Sarah B. Rogers criticized it, posting on X that the revised law endangers tech cooperation and that "it’s better to give victims civil remedies than give regulators invasive license for viewpoint-based censorship."
