Douglas Michael Mallillin

Prior to his appointment as COA Commissioner, Mallillin served as:

• Director IV under the Office of the Chairperson.
• Deputy Commissioner at the National Telecommunications Commission.
• Associate Prosecutor at the Department of Justice.
• Private legal practitioner at the Edgar M. Avila Law Office.

He has also been a professor in taxation, business law, accounting, and criminal law at St. Louis University and Tarlac State University.^[5]

Mallillin was appointed ad interim Commissioner of COA on February 10, 2025, by President Ferdinand R. Marcos Jr., following the end of Roland Café Pondoc’s term on February 2, 2025. His experience in auditing, finance, law, and information and communications technology (ICT) is expected to strengthen COA’s mandate of accountability, transparency, and integrity in government financial management.^[6]

Mallillin was flagged with bias for defending the Department of Finance (DOF) on its order to government owned and controlled corporations including the Philippine Health Insurance Corporation (PhilHealth) to remit money back to the National Treasury.^[7]
