/klɪr ənd ˈprɛzənt ˈdeɪndʒər ruːl/ – Phrase
Definition: (Mỹ) quy tắc về “mối nguy hiểm rõ ràng và hiện thực” (cho phép hạn chế quyền tự do ngôn luận, nêu như những lời lẽ được sử dụng có tính chất và trong hoàn cảnh cụ thể nào đó tạo ra mối nguy hiểm rõ ràng và trực tiếp).
A more thorough explanation: The “clear and present danger” rule is a legal doctrine used in the United States to determine when limitations can be placed on First Amendment freedoms of speech, press, or assembly. Under this rule, restrictions on these freedoms are permissible if the speech or expression poses a clear and present danger of bringing about harmful or illegal actions that the government has a right to prevent. This standard was established by the U.S. Supreme Court in the case of Schenck v. United States (1919).
Example: Under the clear and present danger rule, the government may restrict freedom of speech when there is a clear and present danger that speech will lead to imminent lawless action.
