V. Section 8 of P.D. No. 910, entitled "Creating an Energy Development Board, defining its powers and functions, providing funds therefor and for other purposes," provides that: "All fees, revenues and receipts of the Board from any and all sources x x x shall form part of a Special Fund to be used to finance energy resource development and exploitation programs and projects of the government and for such other purposes as may be hereafter directed by the President." The Malampaya NGO contends that the provision constitutes an undue delegation of legislative power since the phrase "and for such other purposes as may be hereafter directed by the President" gives the President unbridled discretion to determine the purpose for which the funds will be used. On the other hand, the government urges the application of ejusdem generis.
