/ɔːˈθɒrɪti baɪ ɪˈstɒpəl/ – Phrase
Definition: quyền hạn của người đại diện được suy đoán một cách xác đáng căn cứ vào hành vi của người ủy quyền.
A more thorough explanation: Authority by estoppel is a legal doctrine that prevents a person from denying the authority of another person to act on their behalf when the person claiming authority reasonably relied on the representations or conduct of the alleged principal. This doctrine is based on the principle of fairness and prevents individuals from denying the authority of someone who they have allowed to act as their agent or representative.
Example: The company’s actions led the customer to believe that the salesperson had the authority to offer a discount, creating authority by estoppel.
