Hawaii Organic Act § 26

The members of the legislature shall receive for their services, in addition to mileage to and from general sessions at the rate of 20 cents a mile each way, the sum of $1,000 for each general session, payable in three equal installments, on and after the first, thirtieth, and fiftieth days of such session, to be appropriated by Congress from any moneys in the Treasury not otherwise appropriated, based upon regular estimates submitted through the Secretary of the Interior. The sums authorized to be appropriated from the Federal Treasury for mileage and salary of members for general sessions shall constitute the only sums to be appropriated by the Congress for legislative expenses. Members shall receive from the Treasury of the Territory $500 as compensation for any special session held under the provisions of existing law. The Territory of Hawaii is hereby authorized to enact such laws as it may deem appropriate for the payment from the Treasury of the Territory for compensation and mileage to such members for budget sessions and for the payment of additional compensation to such members for general sessions and special sessions.
