What type of authority is granted through a written document in public purchasing?

The correct choice, which pertains to the type of authority granted through a written document in public purchasing, is express authority. Express authority arises from specific written instructions or agreements that clearly define the powers and responsibilities of an individual or entity. In the context of public purchasing, when a purchasing agent is given express authority, it means they have the explicit permission to act in certain ways as outlined in a contract, policy, or other formalized documentation.

This clarity and formality ensure that the purchasing agent can legally bind the organization in transactions, as the authority combines not just the power to act, but a clear mandate from a higher authority. The written document acts as a reference that delineates the scope of the agent's authority and can safeguard both the agent and the organization they represent.

In public purchasing, express authority is necessary to maintain transparency, ensure accountability, and build trust in procurement processes, thus supporting robust governance of public resources.
