What principle underlies the independence of government auditors?

The principle that underlies the independence of government auditors is rooted in the necessity to remain free from conflicts of interest. This independence is critical for ensuring the objectivity and impartiality of the audit process. When government auditors are free from conflicts of interest, they can conduct their evaluations and assessments without being unduly influenced by personal or external pressures. This ensures that their findings and recommendations are credible and trustworthy, which is essential for maintaining public confidence in the integrity of government operations.

The other options do not capture the essence of auditor independence as effectively. Reporting to the agency being audited can create a potential bias, undermining the auditor's ability to remain impartial. Following mandates from the legislative body is indeed part of the auditors’ responsibilities but does not specifically pertain to independence. Prioritizing government employees' rights does not directly relate to the principles of independence required for conducting unbiased audits.
