Section 11
SEC. 11. With the approval of the President of the Philippines, the Board may suspend or withdraw the pension or any part thereof whenever, in its opinion, the reasons entitling a person to receive a pension under this Act have ceased to exist. However, before suspending or withdrawing a pension or any part thereof, the Board shall inform the pensioner, by the most efficient means and as many times as may be necessary, of the actual reasons, charges or allegations by which the suspension, withdrawal, or deduction of his pension is desired, and give him full opportunity to be heard and to defend himself after thirty days, at least, following the receipt of the first notice.
