Who approves the Implementing Rules and Regulations (IRR) of RA 9297?

• A. President
• B. PRC
• C. Board of Chemical Engineering
• D. Senators and Congressmen

Answer: (B)

The main idea here is who has the authority to finalize how a professional law is put into operation. The Implementing Rules and Regulations translate a law into concrete, working requirements, and the body that approves those rules is the Professional Regulation Commission (PRC). The PRC, often after input from the relevant Professional Regulatory Board for the profession, signs off on the IRR so the statute can be applied consistently. The President signs the law but does not approve the IRR, and Senators or Congressmen draft the law, not the IRR. The Board helps draft and advise, but the official approval power rests with the PRC.
