What is a "legal organ" in the context of court proceedings?

In the context of court proceedings, a "legal organ" refers to a newspaper that publishes legal notices, including information about court cases and individuals who have been served with legal documents. This transparency allows the public to be informed about legal actions that may affect them or their interests. Such publications are mandated by law to ensure that there is a broad dissemination of information regarding legal matters, thereby fulfilling the principle of public notice. The choice highlighting a newspaper detailing individuals served to court captures this function and the role that these publications play in the legal system, making it the correct answer.
