The New Jersey Constitution of 1947 (Annotated) Art. V, § I, ¶ 15

15. If any bill presented to the Governor shall contain one or more items of appropriation of money, he may object in whole or in part to any such item or items while approving the other portions of the bill.  In such case he shall append to the bill, at the time of signing it, a statement of each item or part thereof to which he objects, and each item or part so objected to shall not take effect.  A copy of such statement shall be transmitted by him to the house in which the bill originated, and each item or part thereof objected to shall be separately reconsidered.  If upon reconsideration, on or after the third day following said transmittal, one or more of such items or parts thereof be approved by two-thirds of all the members of each house, the same shall become a part of the law, notwithstanding the objections of the Governor.  All the provisions of the preceding paragraph in relation to bills not approved by the Governor shall apply to cases in which he shall withhold his approval from any item or items or parts thereof contained in a bill appropriating money.
