Which of the following terms refers to the legal right to make decisions on behalf of someone else?

The term that refers to the legal right to make decisions on behalf of someone else is "Agency." In legal contexts, agency is a relationship where one party, known as the agent, is authorized to act on behalf of another party, the principal. This arrangement allows the agent to enter into contracts, make decisions, and perform various acts as if they were the principal themselves.

Agency is fundamental in various legal scenarios, including business dealings, where an agent may represent a company in contracts or negotiations. The concept is embedded in many legal doctrines and principles, such as the duty of loyalty and the duty to act in the best interest of the principal. When establishing an agency relationship, the principal must grant the authority willingly, and the agent must act within the scope of that authority.

Authority generally refers to the power or right to give orders, make decisions, or enforce obedience, but it does not imply representation on behalf of someone else. Mandate often refers to a formal order or commission, which can include elements of agency but lacks the broad transactional implication of representing another party. Consent is about permission or agreement, which is essential
