Which document or standard regulates the conduct of the investigated persons mentioned?

The EGP Act is crucial in regulating the conduct of investigated individuals as it provides a legal framework under which professional conduct and responsibilities are outlined. This act establishes the legal standards and obligations that professionals must adhere to, especially in circumstances surrounding investigations. It lays down the principles that guide ethical practice and may include provisions for compliance, accountability, and legal repercussions for breaches of conduct.

While other options, such as The Charter of Professional Duties or The Discipline Committee Guidelines, may also address professional expectations and conduct, they are typically more specific to the procedural aspects of enforcement rather than the overarching legal guidelines. The ASET Ethics Code focuses on ethical principles and moral standards but does not hold the same legal authority as the act itself. In contrast, the EGP Act serves as a foundational legal document that governs professional conduct in a broader and more regulated manner, making it the correct choice for the question regarding the regulation of conduct of investigated persons.
