Section 46. Certification of Availability of Funds. —

No funds shall be disbursed, and no expenditures or obligations chargeable against any authorized allotment shall be incurred or authorized in any department, office or agency without first securing the certification of its Chief Accountant or head of accounting unit as to the availability of funds and the allotment to which the expenditure or obligation may be properly charged.

No obligation shall be certified to accounts payable unless the obligation is founded on a valid claim that is properly supported by sufficient evidence and unless there is proper authority for its incurrence. Any certification for a non-existent or fictitious obligation and/or creditor shall be considered void. The certifying official shall be dismissed from the service, without prejudice to criminal prosecution under the provisions of the Revised Penal Code. Any payment made under such certification shall be illegal and every official authorizing or making such payment, or taking part therein or receiving such payment, shall be jointly and severally liable to the government for the full amount so paid or received.
