In this situation, the appropriate action for the internal auditor is to remain independent and avoid roles that could impair this independence, such as making managerial decisions. By advising and then directing the management to submit the proposal to senior management and the board, the auditor maintains an advisory role without crossing into decision-making territory, thus preserving the independence necessary for an assurance role.References: Institute of Internal Auditors (IIA) - International Standards for the Professional Practice of Internal Auditing

For the internal audit activity to achieve conformance with the Standards, it is crucial that the internal audit charter has been approved by the board within the past year. Regular approval and review of the charter by the board ensure that it remains relevant and aligned with the organization's objectives and governance frameworks. This approval process is part of maintaining the necessary authority and scope as prescribed by The IIA standards.References: The IIA's International Standards for the Professional Practice of Internal Auditing on charter review and approval.
