Notwithstanding Article X, § 12(d) of this constitution, no new State tax or fee shall be imposed on or after November 8, 1994 by any amendment to this constitution unless the proposed amendment is approved by not fewer than two-thirds of the voters voting in the election in which such proposed amendment is considered. For purposes of this section, the phrase “new State tax or fee” shall mean any tax or fee which would produce revenue subject to lump sum or other appropriation by the Legislature, either for the State general revenue fund or any trust fund, which tax or fee is not in effect on November 7, 1994 including without limitation such taxes and fees as are the subject of proposed constitutional amendments appearing on the ballot on November 8, 1994. This section shall apply to proposed constitutional amendments relating to State taxes or fees which appear on the November 8, 1994 ballot, or later ballots, and any such proposed amendment which fails to gain the two-thirds vote required hereby shall be null, void and without effect.
