Section 16
SEC. 16. Act No. 3513 as amended and Republic Act No. 4630 are hereby repealed; and all laws inconsistent with this Act are accordingly modified or repealed, insofar as the Grantee herein is concerned. If any part of this Act shall, for any reason, be adjudged by any court of competent jurisdiction to be invalid, such judgment shall not affect the remainder thereof, but shall be confined in its operation to such part directly involved in the controversy in which such judgment shall have been rendered.
