/ɛks əˈfɪʃiˌoʊ/ – adj
Definition: theo chức trách, theo chức vụ, mặc nhiên, đương nhiên.
A more thorough explanation: “Ex officio” is a Latin term that means “by virtue of one’s office or position.” In legal terms, it refers to the authority or right that a person has because of the position they hold, rather than because of any specific action or decision they have made. For example, a board member may have the ex officio right to attend certain meetings by virtue of their position on the board, even if they were not specifically invited.
Example: The attorney general, ex officio, serves as the chief legal advisor to the government.
