What restricts an agency's demands during an investigation?

The correctness of this answer stems from the established legal standards that govern the demands made by an agency during an investigation. Agencies are required to adhere to principles of reasonableness, which means that their demands must serve a legitimate purpose, be relevant to the investigation at hand, and must not impose an undue burden on the parties being investigated.

This requirement ensures that while agencies have the authority to gather information and conduct investigations, they do so within a framework that balances their needs with the rights and interests of those being investigated. Ensuring that demands are proportionate and justified is crucial for maintaining fairness and legality in administrative procedures.

This principle protects individuals and businesses from arbitrary or excessive demands that could infringe upon their rights. It serves as a guideline for agencies to follow, confirming that their investigative powers are not limitless and must be exercised judiciously.
