One-tenth of the interest and income derived from the trust fund on or after January 1, 2001, shall be deposited in the trust fund. The principal of the trust fund and one-tenth of the interest and income deposited in the trust fund shall remain forever inviolate unless appropriated by a vote of two-thirds of the members of each house of the legislature.
