/ˈviːtəʊ ruːl/ – Phrase
Definition: quy tắc quyền phủ quyết.
A more thorough explanation: A veto rule is a provision in a decision-making process that allows a single participant or entity to block a decision or proposal from being adopted, even if it has majority support. This veto power gives the individual or entity the authority to prevent the decision from being implemented.
