The Constitutional Court of Korea found that Section 47 0f the Electronic Communications Act violated the rule of clarity through its use of the term "public interest." The Court reasoned that laws restricting freedom of expression must be clear and explicit and that a provision punishing those who communicate false information with an intent to harm the public interest was unclear because it failed to define what harm to the public interest would constitute a crime. Further, the term "public interest" in the provision was fluid and would vary depending on each individual's background so that it was not sufficiently clear to survive the strict scrutiny review applicable to laws  restricting freedom of expression.
