"By the authority of” refers to a phrase that establishes the legitimacy or authorization of an action, decision, or statement. It implies that the action has been officially sanctioned, approved, or granted permission through a specified authority figure or entity. When something is done or said "by the authority of" a particular person, organization, government, or law, it suggests that this individual or body holds the power and right to enforce rules, make judgments, or give orders in a formal capacity.
The phrase is commonly used in legal, administrative, or governmental contexts to emphasize the source of power and assert that an action is being taken in accordance with established regulations. It indicates that an action is being carried out with the full endorsement and backing of the responsible authority, enhancing its legitimacy and preventing challenges or objections based on unauthorized actions.
For instance, a document may declare that an individual is granted certain privileges "by the authority of" a specific law or the person holding a particular position. Similarly, a military order could be issued "by the authority of" a commanding officer, signalling that it must be obeyed and is binding on personnel under their command. In summary, “by the authority of” is a phrase that establishes the official endorsement, permission, or power behind an action, conveying the notion that it has been sanctioned by an authorized entity.
